The Biloxi-Chitimacha-Choctaw Indians are not strangers to the idea of forced migration. As a consequence of the Indian Removal Act of the 1830s, the tribe’s ancestors moved to the Isle de Jean Charles.  Almost two hundred years after, they are being forced to move again as a result of climate change.

To address this issue, the federal government has provided 48 million dollars in order to move a majority of the island’s population of 85 people. Although the federal government has provided grants totaling one billion dollars for thirteen states, funding for “climate change refugees” is unprecedented.

The results of this program are fundamental in providing a potential blueprint for future resettlements resulting from climate change.  It is estimated that 13.1 million Americans living seaside might face flooding as a result of rising sea levels. The issue of resettlement is complicated in itself. The issue in Isle de Jean Charles, however, is particularly complex because of the need to preserve what remains of the Biloxi-Chitimacha-Choctaw Indian community.

The story of the Isle de Jean Charles is particularly intriguing because of just how severe the ramifications of climate change combined with the increased rate of natural land loss due to the construction of dams and oil drilling. Isle de Jean Charles has lost 98% of its territory. Furthermore, frequent flooding and hurricanes have made farming impossible, contributing to the outward migration that has been occurring since 1955. The ones that have stayed behind despite worsening conditions, however, are strongly attached to their land, raising the broader question of how resettlement be carried out if the population in peril, refuses to move.

The Biloxi-Chitimacha-Choctaw Indians have voted twice before against resettlement. The issue of resettlement came up in 2002 when the Army Corps of Engineers (ACE), which had originally planned to include the Isle de Jean Charles in Gulf Hurricane Protection System, decided the cost and benefit did not add up. Because of the Isle’s remote location and relatively low economic value, ACE did not see the benefit. Instead, they offered the locals a plan of resettlement which, lacking unanimous support from the locals, were not implemented.

The Biloxi-Chitimacha-Choctaw Indians certainly won’t be the last U.S. climate refugees. In Alaska, more than 180 villages are currently directly affected by melting ice glaciers. A village called Newtok, according to Army Corps of Engineers is expected to be under water by next year. The locals, Eskimos, have been noticing the sinking for twenty years now and have been slowly rebuilding their community further inland. However, just as can be seen with the Biloxi-Chitimacha-Choctaw Indians, the effect displacement will have on a community so intimately connected to its land, given that they live off of it, is yet to be seen. Newtok, Alaska is one of many locations under the danger of going underwater. Tangier Island in the Chesapeake Bay and Quinault Indian Nation on Washington’s Olympic Peninsula are undergoing a similar catastrophe.

As part of the legacy he wants to leave on the issue of climate change, President Obama should ask Congress to set aside special funding for the next wave of climate refugees.

West fertilizer facility explosion 2Friday, May 13 Marks Deadline for comments to the proposed EPA Rules for Chemical Facilities such as the fertilizer plant involved in the West, Texas explosion.

The draft EPA Rule Fails in Protecting the Public as 87% of such Facilities Are Exempted by Federal Agency

Friday the 13th marks the deadline for the EPA’s proposed new rules on unique high risk chemical plants which are to urge the use and access to safer technologies to protect public health and welfare.

Public Citizen maintains that the new rules fall short of any real teeth to require industry to do what is needed, instead opting for too many voluntary measures of compliance to be protective of communities where these hazardous chemical facilities are sited.

“Though we commend the EPA’s attempt at new rules to rein in careless plant owners and operators,” commented Rita Beving, Public Citizen North Texas organizer,  “These rules are simply weak, falling woefully short in the effort to protect the communities where these plants are located.”

“More than 87% of the facilities of the 12,543 facllities that should be regulated are exempt including water treatment facilities,” added Beving. “The way this rule is currently written still places cities such as DFW along with smaller communities which have such hazardous facilities at risk.”

The proposed rules entitled “Modernization of the Accidental Release Prevention Regulations under the Clean Air Act” were devised as a result of the deadly fertilizer plant explosion in West, Texas and other chemical plant disasters.  Since West’s disaster in 2013, 82 people have been killed and 1,600 have been injured in more than 400 chemical plant incidents.

“There is still time to comment today and tomorrow on these proposed rules,” commented Tom “Smitty” Smith, Public Citizens Texas director.  “We need to tell the EPA that too much of these new rules are voluntary. The rule fails to have the needed mandates that require industry to comply or improve the safety aspect of their operations.

“Instead of a patchwork of locations where these hazardous industries will be allowed to disclose their chemical information, there needs to be one singular database for emergency responders and officials to get the information they need in regards to these facilities,” added Smith.  “This is just common sense safety for all our communities.”

According to facility reports to the EPA, over 100 million Americans still live in chemical hazard zones. In addition to putting facility employees at risk, communities closest to hazardous facilities are disproportionately African American and Hispanic.

Public Citizen asks that the EPA rule be strengthened by adopting the following measures within the new rules to protect public health and the communities in which they live:

  • Require these unique hazardous facilities to use safer technologies and alternatives where they are feasible to prevent future disasters.
  • Require all hazardous chemical facilities to conduct Safer Technology and Alternatives Analysis (STAA) –  including water treatment facilities.
  • The proposed rule now exempts 87% of the 12,543 (RMP) chemical facilities from requirements to conduct Safer Technology and Alternatives Analysis (STAA) including water treatment facilities, some of which put major cities at risk of a catastrophic release of chlorine gas. An Safer Technology and Alternatives Analysis shouldbe required of all facilities.  An STAA involves reducing risks through a tiered approach of minimizing risk by reducing the amount of hazardous chemicals stored, employing physical barriers to mitigate hazard, utilizing emergency controls/sensors, and having safety and evacuation procedures in place.  These plants’  STAA plans should also be accessible to the public.
  • The proposed rule now exempts 87% of the 12,543 (RMP) chemical facilities from requirements to conduct Safer Technology and Alternatives Analysis (STAA) including water treatment facilities, putting major cities and other      communities at risk of a catastrophic release of chlorine gas.
  • The rule should require chemical facilities to report their Safer Technology and Alternatives Analysis to the EPA.  These analyses should be accessible to the public.
  • The EPA should establish an online clearinghouse of safer technology and available alternatives for these unique chemical facilities that would encourage and support plants’ adoption of safe technology alternatives.
  • The EPA should devise a one stop, 24/7 accessible database of information via web requiring information about  a chemical facility’s hazards that is accessible to public officials and emergency responders.

Currently, the proposed rule suggests using a patchwork of company web sites, libraries or government offices to disclose information on facility hazards to emergency planners and community residents. By not having these facilities utilize one accessible database of disclosure, companies can conceal the results of their assessments from local residents, schools, and hospitals near these facilities.

  • Require buffer zones around existing facilities or restrictions on the location of new facilities in populated areas.

Below are examples of chemical incidents that led to the EPA rulemaking:

  • April 17, 2013 – an explosion at the West Fertilizer facility in West, Texas killed 15 people.
  • March 23, 2005 – explosions at the BP Refinery in Texas City, Texas, killed 15 people and injured more than 170 people.
  • April 2, 2010 – an explosion and fire at the Tesoro Refinery in Anacortes, Washington, killed 7 people.
  • August 6, 2012 – a fire at the Chevron Refinery in Richmond, California, involving flammable fluids endangered 19 Chevron employees and created a large plume of highly hazardous chemicals that traveled across the Richmond, California, area.       Nearly 15,000 residents sought medical treatment due to the release.
  • June 13, 2013 – a fire and explosion at Williams Olefins in Geismar, Louisiana, killed 2 people and injured more.

Today, the U.S. Environmental Protection Agency (EPA) released a final rule to reduce methane emissions from the oil and gas sector.

Today’s announcement of a regulation designed to monitor and capture methane emissions from not-yet-built oil and gas operations is an important step for the U.S. to combat climate change in the decades to come. But under this rule, methane emissions from existing oil and gas operations will remain unmonitored and uncontrolled.

The EPA’s March announcement of an Information Collection Request to poll the industry as to the feasibility of monitoring and controlling emissions from existing operations will take years, and it could be years before a final rule that applies to existing operations is developed. The climate simply can’t wait that long. The EPA can and should start working on a rule to cover existing methane emissions now.

Research into one of America’s two major oil fracking sites found that the Bakken Shale is leaking 275,000 tons of methane annually. As a greenhouse gas, methane is 87 times more harmful than carbon dioxide. The oil and gas industry has a responsibility to begin monitoring and reducing emissions from existing sources immediately – and the public has the right to expect the EPA to do as much.

As we’re all aware, weather is never static. Weather conditions and patterns are always changing and are difficult to predict. One very recent example of this is the El Niño Southern Oscillation (ENSO). ENSO is a cycle of warming and cooling events in the equatorial Pacific Ocean and the atmosphere above it. These periodic events take place over roughly 2-7 year intervals. The resulting variability in oceanic and atmospheric temperatures has a range of effects on seasonal precipitation and temperature patterns across the world.

With ENSO, the cycle can shift form its neutral or normal state, to a warm phase – El Niño, or a cool phase – La Niña. We’ve been in one of the strongest El Niño phases on record for the last 2 years. During El Niño, the typical East-to-West winds weaken in the equatorial Pacific, which drives warm waters from the western Pacific to the eastern Pacific. This causes warm ocean surface temperatures and heavy precipitation in northern South America, and dry conditions in Australia and Indonesia.

El Nino

With the El Niño phase we’re currently in, there have been a lot of extreme weather phenomena. The monsoon rains weakened in India, resulting in food shortages, West Africa has been in a drought, Australia experienced record heat, Brazil experienced excessive rains, and the northern hemisphere winters were warmer than usual. For Texas specifically, there’s been increased precipitation events, making 2015 Texas’ wettest year on record.

Winter Comparison - NOAA Climate.govThis month though, scientists from the National Oceanic and Atmospheric Administration (NOAA) have issued an official “La Niña Watch.” They predict that El Niño will phase out in late spring or early summer, and will shift to La Niña for the fall and winter. So we can soon expect to see generally opposite conditions than we have been experiencing with El Niño.

La Niña results when cool ocean water intensifies the East-to-West winds across the equatorial Pacific Ocean. This causes warm oceanic temperatures in the western Pacific, which means heavy rainfall for Australia and Indonesia. Conversely, it causes cool oceanic temperatures in the eastern Pacific, resulting in dry conditions in South America.

Nina Winter - Weather NetworkDuring La Niña winters, the U.S. experiences dry and warm conditions in the southern states, but wet and cool conditions in the Pacific Northwest and northern plains. We can expect there to be a lot of snow in the Pacific Northwest while there’s drought in California and Texas. In previous La Niña periods, the lack of rainfall negatively impacted Texas water supplies and crops. With La Niña, there’s also an increased chance of Atlantic hurricanes since the temperature and moisture flow associated with it creates ideal conditions for hurricane formation.

Even worse, research indicates that because of global climate change, El Niño and La Niña may hit twice as often as they did before. Climate models indicate that an extreme La Niña may hit every 13 years now instead of every 23 years, and an extreme El Niño may hit every 10 years now instead of every 20 years. Since a warmer atmosphere can hold more water and moisture, rainstorms can increase in intensity. For example, during a future El Niño, the West Coast may experience heavier downpours than usual. During a future La Niña, the added moisture in the air may make northeast snowstorms much stronger.

If the weather is always undergoing different cycles and is constantly changing, then why does an upcoming La Niña matter? Shifts in precipitation and temperature patterns alter crop production abilities, which will impact the prices of goods all over the world. Various commodities will be affected by the upcoming La Niña:

ntulogoTexas is a beautiful state – full of unique landscapes from the rocky desert of Big Bend to the colorful, rolling Hill Country. With that said, it is essential we remember that before settlers staked claim to this region of America, it was already sacred land to the Native Nations. It can be seen that modern industry has exploited this bountiful and revered land for its natural resources to build the current civilization. Few are guiltier of this than the coal industry whose mines completely decimate the land they are built upon.

For this reason and more, members of the Native People of the Americas and community allies have united in opposition against the Dos Republicas coal mine in the area near Eagle Pass, Texas. Since being proposed in 2012, the Dos Republicas coal mine has faced continuous criticism by concerned citizens of Eagle Pass and outcry in on the southern side of the border in Mexico.  Despite united and continued opposition from local residents and local governments, the Texas Commission on Environmental Quality (TCEQ) and the Railroad Commission (RRC) granted Dos Republicas the permits needed to move forward with the mine.

Not only will this mine bring tremendous environmental damage on this sacred land, but it will also be used as the supplier of coal to be burned at plants in Mexico instead of the local energy grid. This is because the coal in this area is of such low quality that it can’t be burned in the United States. So this dirtiest of dirty coal will be shipped across the border and burned in plants with little or no air pollution controls. The subsequent pollution will harm local communities and blow across the border to impact Texans as well.

Projects such as these are last ditch efforts by the coal industry to remain profitable in an adapting energy market, and these attempts corner rural and native communities who will bear the burden of their desperation. Profit and energy aside, the extraction and production of coal puts neighboring communities at risk. The silt, pollution, and waste of such a mine all present toxic impacts to the region, which are especially relevant considering the rise of flooding in recent years.

With the climate crisis looming over us, as well as our right to live in a healthy and safe environment, it is entirely necessary to confront new coal mines head on.

A Native led rally and march to the Dos Republicas Coal Mine will be taking place this Saturday, April 16, 2016. For updates, go to the event page. Public Citizen stands in solidarity with their action and will continue to work towards a cleaner, more just Texas.

DA general 6If you pay any attention to politics, you might often wonder if the decisions being made are really what people want.  The answer is often no.

Wealthy donors, including corporations and individuals, are able to contribute unlimited money to super PACs (political action committees) to support or oppose candidates for elected office.  Although this money is technically separate from donations directly to candidates, super PACs are clearly working in lock-step with candidates’ campaigns.  On top of that, the Supreme Court ruling in Citizens United v. Federal Election Commission opened the door for unlimited spending on campaigns by political nonprofit organizations, which don’t have to disclose their donors.  So, wealthy individuals and powerful business interests can secretly spend unlimited money on elections.  And they are.  This results in elected officials who are beholden to those wealthy donors, not the people.  Does that sound like democracy?

In addition to the corrupting influence of money on politics, the basic right to vote is under constant attack.  In 2013, the Supreme Court struck down a key provision of the Voting Rights Act, which required certain states, including Texas, to receive authorization from the federal government before changing how elections are conducted. That provision caused hundreds of proposed changes to be withdrawn or altered because the Justice Department was concerned that they may be discriminatory.  Now, those states can enact potentially discriminatory elections laws and they much be challenged through the court system by those who are harmed.  This adds expense and, much more importantly, results in the denying citizens their right to vote.  Another major blow to democracy.

Enter Democracy Awakening.  Over 200 organizations representing a broad array of interests – civil rights, the environment, labor, peace, students – are working together to bring national attention to the problems caused by the influence of money on politics and voter disenfranchisement.  There will be a large rally and other events in Washington D.C. and supporting events in cities across the country on Sunday, April 17.

Austin Rally: Sunday, April 17 at 1 p.m. in the southwest corner of the Capitol grounds in Austin.  There will be short speeches, music, tables with information and a march down Congress Ave.

Dallas Rally: Sunday, April 17 at 1 p.m. at the Reverchon Park Recreation Center (3505 Maple Ave).  The event will include speeches, activities, tables with information and a march to Lee Park.

Regardless of what issue you care about most, the degradation of our democracy by denying voters their rights and allowing unlimited sums of money to determine political outcomes is a serious threat.  I need look no further than my top priority, climate change, to see many examples of how money, not voters are determining policy decisions.  A large majority of Americans want action to stop climate change, and yet Congress has failed to place limits or a tax on greenhouse gas emissions.

Please join us to rise up and defend our democracy by demanding reforms.

Dylan Petrohilos - Gov Census

2014 and 2015 were back-to-back years that both earned the title for hottest year on record. and February 2016 was the warmest month, globally, ever recorded. And yet U.S. lawmakers continue to deny the facts.  Earlier this month, the Center for American Progress Action Fund (CAPAF) released an analysis of climate change denial in U.S. Congress called “The 2016 Anti-Science Climate Denier Caucus.” Their research found that more than 63% of Americans are represented by someone in Congress who denies that climate change exists.

Dylan Petrohilos - CAP182 members of Congress don’t believe the science behind climate change: 144 members in the House of Representatives and 38 members in the Senate. 67% of Americans want the U.S. to take action on climate change, but 202 million citizens are represented in Congress by a climate change denier. Since the Republican Party’s platform on environmental policy never mentions climate change, it’s no surprise that every single denier is a member of the Republican Party.

A recent poll revealed that 76% of Americans believe global climate change is occurring, including 59% of Republicans. According to a poll by NBC News and the Wall Street Journal, 67% of Americans support President Obama’s Clean Power Plan. The results of these polls don’t correlate with the fact that that the number of Congressional climate deniers has increased from previous years. From severe weather, wildfires, drought, and flooding, climate change is impacting Americans every day, and it’s evident that human activity is the dominant cause. Despite this evidence, 70% of the Senate GOP still denies climate change.

Dylan Petrohilos - Open SecretsIn the analysis, CAPAF also looked into dirty energy money’s influence over Congress members. They found that climate deniers in Congress received more than $73 million in contributions from coal, oil, and gas companies. This is an increase of nearly $10 million from last year. When asked about their views on climate change, many deniers dodge the question by saying “they aren’t scientists”.

According to Sondre Båtstrand, a Norwegian researcher, the U.S. Republican Party is the only conservative party in the world which denies the reality of climate change. Båtstrand believes the GOP’s denial is due to three factors: the fossil fuel industry’s political spending, a commitment to free-market ideology, and the intense political polarization that punishes moderate-minded party members.

In February 2016, over 200 lawmakers in U.S. Congress signed onto a court brief opposing the president’s Clean Power Plan. At the end of 2015, the House of Representatives passed two resolutions to kill the Clean Power Plan. The Plan would regulate power plants’ carbon emissions and 67% of Americans support it. So it’s clear that Congress isn’t working the way it’s intended to. Members of the House and Senate are elected to represent the interests of American citizens, not their own fat wallets and the interests of dirty energy companies.

Regarding the state of Texas specifically, the 2016 Anti-Science Climate Denier Caucus found that 17 out of 38 Texas Congressional members are climate change deniers. In 2016, this is not only unacceptable, but is dangerous for Texas families who depend on their elected leaders to protect their futures. When the impacts of climate change become more and more apparent each year – more severe storms, deadly wildfires, crippling drought, and rising sea level – it’s clear there’s no time to waste. Climate change deniers in Congress, like Ted Cruz, stand in the way of these common sense safeguards. Texans and Americans across the country deserve leaders who will stand up to face this threat head on – not those following the playbook of their largest campaign donors.

wind and solarWind knocked out nuclear to take third place as one of the major sources of energy in the Electric Reliability Council of Texas (ERCOT)’s system this year. ERCOT is the grid manager for the bulk of the state of Texas and stays on top of which power source is feeding into the grid at any given moment.  Nuclear power met 15.1% of demand last month, coming in fourth behind natural gas, wind and coal.

In February 2015, wind supplied only 11.8% of ERCOT’s demand, behind natural gas at 47.6%, coal at 26.5%, and nuclear energy at 13.7%.

Led by Texas, the U.S. wind industry is booming and is expected to continue record expansion into the early 2020s due to the recent 5 year extension and phase out of its $0.023/kWh production tax credit.

Texas added 3,615 MW of new capacity in 2015, more than twice of Oklahoma’s total of 1,402 MW, according to the American Wind Energy Association. Texas now has an installed capacity of more than 17,713 MW, more than twice of Iowa’s 6,212 MW. Texas also had 53% of all U.S. wind capacity under construction at the end of 2015.

Due to a mild winter in Texas, demand declined in February.  ERCOT’s system demand peaked on February 4 at 47,397 MW, down from the previous month’s demand peak of 49,250 MW on January 11 and  the demand peak around same time last year at 54,539 MW.

A quick recap of the above:

  • Electricity demand in the Electric Reliability Council of Texas (ERCOT) fell February, but wind energy increased to supply nearly one out of every 5 MW of energy.
  • Compared to February 2015, the ERCOT system used nearly 4.7 TWh of wind energy February, 14.3% more than the amount of wind energy generated at the same period last year, according to according to ERCOT’s monthly Demand and Energy report.
  • Wind composed 19.9% of total energy on ERCOT’s grid in February, behind natural gas, which led with 43.2% of February demand, and coal, which supplied 21.2%.

Solar is making some inroads into the state’s power portfolio, but has not had the policy boost that wind got in 2005 with the passage of the Renewable Portfolio Standard (RPS).  Nevertheless, with costs coming down and with investments nationwide in utility scale solar “farms”, yet another renewable source is becoming a viable option for replacing fossil fuel sources of electricity.  In another 10 years, Texas’ energy portfolio could look very different from that of 2015.

As a global industry, aviation produces 2% of the planet’s total carbon dioxide emissions. Its outlook isn’t good either, because it’s projected to grow by 3-4% each year as the industry expands. While air travel has become 70% more efficient per seat-mile than when jets first began operating in the 1960s, the industry’s growth has resulted in higher overall CO2 emissions.NASA Armstrong

NASA’s project LeapTech is in the process of testing a new approach to powering flight. The concept is called distributed propulsion, and it’s the future of low-carbon aviation. Paul J Willett - We Love The Stars Too Fondly (with truck)The project features a 30-foot airplane wing – the kind found on a small plane. The new wing design has 18 electric motors with small propellers along its leading edge.

Engineers attached the wing to steel supports on a Peterbilt truck, and have been simulating takeoff and landings at the Edwards Air Force Base in California. They have driven the wing-truck contraption down the runway at more than 70 miles-per-hour.

The idea behind distributed propulsion is to take the engines from their usual position hanging below the wings and put them elsewhere. Because jet engines are complex, heavy devices, distributed propulsion designs almost always involve simpler and smaller electric motors.

Paul J Willett - We Love The Stars Too Fondly (close-up)Distributing the motors around the plane (instead of in just one spot) has aerodynamic advantages. The position of the motors on the leading (front) edge of the LeapTech wing results in accelerated airflow over it, which increases lift at takeoff and landing. Because of this, the wing can be made narrower, which reduces drag and improves efficiency at cruising speeds.

In terms of reducing an airplane’s carbon footprint, the key is cutting down on the plane’s weight and drag, and reducing the engine’s excess fuel burn. Some planes have been partly redesigned. In the coming years, Boeing will introduce the 777x, a variant of their 777 model. However, the new design of the 777x features composite wings and more efficient engines than the traditional 777. But the basic design of airplanes still remains the same – a tube and wings.

Besides NASA’s LeapTech project, there have been other innovations in airplane technology. Engineers have made planes lighter by using composite materials, jet engines have become more efficient, and alternative biofuels are increasingly being used. Better management of airplane traffic at airports and in the air has also reduced emissions. Many of the aviation industry’s improvements involve changes to existing planes though – like replacing older engines with more efficient models, or adding winglets to wings to reduce drag and improve efficiency.

In the future, NASA thinks that planes could be powered by hybrid gas-electric systems or by batteries. Potential designs could have lighter wings that can quickly shape to handle turbulent air. Other concepts could eliminate the conventional tube and wing design for one that blends the two elements.

For NASA, the next step is modifying an actual aircraft to operate with batteries and wing motors. NASA’s LeapTech project uses batteries, but the modified aircraft will only be able to make short flights because of the current limitations of batteries. All-electric planes may never be a practical option, but a hybrid turbine-battery design could be a reality.

Despite these scientific advancements, emissions from the aviation industry are still growing at a rapid pace. The International Civil Aviation Organization, a United Nations agency, projects that the worldwide commercial fleet will double to 40,000 airliners in the next 15 years. A recent report from the European Parliament revealed that international aviation could be responsible for more than 20% of global CO2 emissions in the near future. Aviation emissions impact cloud formation, ozone generation, and methane reduction, so the report’s projection isn’t a good sign.

In order to deal with the rising growth of the aviation industry, we must make drastic changes to airplane design to protect the environment. NASA’s LeapTech project is a step in the right direction towards making airplanes more eco-friendly, and more airplane engineering companies should take note.

Today, Supreme Court Chief Justice John Roberts rejected a plea to stay or enjoin further operation of the Mercury and Air Toxics rule.  This is a big victory for the Obama administration, the EPA and environmentalists.

Roberts’s order came despite his court’s 5-4 decision last year ruling that the Environmental Protection Agency’s (EPA) regulation, known as the Mercury and Air Toxics Standards, is illegal, and he acted swiftly, waiting less than a day after the EPA’s response brief to side with the Obama administration. Furthermore, Roberts acted unilaterally, electing to reject the request himself rather than take it to the full court, which may have led to a 4-4 split following Justice Antonin Scalia’s death.

The mercury pollution standards, made final in 2012, are a separate regulation from the more controversial and costly carbon dioxide limits for power plants that are also being litigated in court.

The Supreme Court put an unprecedented halt to the carbon rule, known as the Clean Power Plan, last month by a 5-4 vote, when Roberts chose to let the full court vote on the matter. Thursday’s action by Roberts is completely separate from that case and the EPA says it plans to finalize a fix to the rule to retroactively apply its cost-benefit analysis in the way the Supreme Court said was necessary by next month which should move the rule forward toward protecting public health.

If you felt like 2015 was exceptionally warmer than usual, you weren’t alone. Last month, scientists declared 2015 the hottest year on record. Some of this heat can be attributed to the El Niño weather pattern releasing heat from the Pacific Ocean into the atmosphere, but most of the record-breaking heat is from climate changes caused by human-related greenhouse gas emissions.

NASA, the National Aeronautics Space Administration, and NOAA, the National Oceanic and Atmospheric Administration, both collected data that showed that 2015 was between 0.23-0.29 degrees Fahrenheit hotter than 2014. This number may seem small and insignificant, but in terms of global temperature, it’s a big deal.  Thomas Karl, director of NOAA’s National Centers for Environmental Information emphasized that point:

This record, we literally smashed. It was over a quarter of a degree Fahrenheit, and that’s a lot for the global temperature.

In comparison to average temperatures in the 20th century, and not just 2014, 2015 was 1.62 degrees Fahrenheit higher.

2015 Hottest Year

Heat StrokeThe severe heat last year was felt around the world. There were record-high temperatures in the triple digits across Europe in June and July in Spain, Portugal, France, the U.K., Germany, and Poland. In May, India experienced 120 degree days that melted the asphalt, killing 2,500 people. In June, 1,200 people died in Pakistan after temperatures reached 113 degrees. When the atmosphere is warmer, it can hold more water vapor, which can cause an increase in heavy rains. The recent catastrophic floods in the eastern U.S. are evidence of this. El Niño is also disturbing atmosphere circulation which is causing some worldwide weather extremes like the drought in southern Africa.

So how will Texas be affected by this global climate change? With its location and vast size, Texas has a wide range of vulnerabilities to the effects of climate change. A study done by the Risky Business Project found that Texas will be one of the states that is most negatively affected by climate change.

Texas by 2050:

  • Decrease in worker productivity and crop yields.
  • Sea level rise of 2 feet in Galveston.
  • The number of extremely hot days per year (temperatures exceeding 95 degrees) will more than double from 43 to 106 days per year.
  • About 4,500 additional heat-related deaths per year.
  • A $650 million per year increase in storm-related losses along the coast, bringing the state’s annual damages to more than $3.9 billion.

Texas Climate

The Risky Business Project’s mission is to convince business leaders in Texas that climate change is a true risk. This will not be easy since Texas lawmakers routinely dismiss climate change. Regarding the news that 2015 was the hottest year, NASA head Charles Bolden said, “This announcement is a key data point that should make policymakers stand up and take notice – now is the time to act.” That it is, Bolden.
