In advance of the United Nations Secretary General’s climate summit in September, many countries are vowing to ramp up their Paris agreement commitments to help limit the increase in global temperatures to 1.5 degrees Celsius. However, the growing emissions from two economic sectors – international shipping and international aviation – remain largely outside most of those commitments and could cause significant warming.

In a new study, researchers have found that, absent any climate action, the rising carbon dioxide emissions of international shipping and aviation could consume nearly one-third (15 to 30 percent) of our remaining “allowable warming” – the amount of additional warming that can occur before the world’s average temperature surpasses 1.5 to 2 degrees Celsius above preindustrial levels – by the end of the century.

The international shipping and aviation sectors need to implement policy solutions with integrity and extend them over time to reduce their future warming and align with the 1.5 °C global temperature threshold.

The Trump Administration’s Budget Would Make our Climate Crisis Even Worse

Scientists around the world are telling us, in no uncertain terms, that we – as in humankind — have little time left to avert the worst impacts of climate change. Those include: widespread coastal and riverine inundation, stronger storms and wildfires; new disease vectors; agricultural and other economic disruption. That is the reality and scope of the challenge we face.

There are, of course, things we can do — things we must do – to respond to the climate crisis, both to learn more about its causes and consequences and to activate solutions to prevent as much damage as possible.

Those solutions, for the most part, fit into four areas: investment, innovation and technology; science and research; mitigation, adaptation and relief; and policy. An intransigent and shortsighted White House has made the achievement of any significant policy gains difficult in the short term. Now, the latest federal budget proposed by the Trump Administration has sought to undercut those other three potential progress areas, exacerbating America’s susceptibility to climate disaster and running down the clock on desperately needed action.

Latest EPA climate pollution data shows disturbing lack of progress

Greenhouse gas emission trends since 1990. Click to expand

The Environmental Protection Agency yesterday reported that that the US made essentially no progress on climate pollution — an insignificant drop of 0.5% — even as scientists warn that without major reductions in emissions, global temperatures are on a dangerous track to increase well above 2 degrees Celsius.

Other data indicates that since 2017, the last year covered by this report, emissions have actually begun to rise. The Energy Information Agency and Rhodium Group estimate that in 2018 climate pollution from energy combustion rose 2.8 and 3.4%, respectively.

As climate pollution remains stubbornly high, the Trump administration has worked to undermine limits on carbon pollution, roll back rules on highly potent methane emissions and ducked international obligations to deal with climate change. This new report is another sign that without bold action, climate pollution will cause worsening impacts on our economy, health and future.

The dismal national climate pollution numbers contrast with pollution reductions underway in many states that have put in place aggressive policies to limit emissions and move towards clean energy even while the federal government sits on the sidelines. Read More »

Heatwaves to become more deadly and increase global inequality

A new study shows that heatwaves will worsen in the future and that the most vulnerable populations will be hit the hardest

Human-caused climate change has already increased the frequency and severity of heatwaves across the globe, and new research shows that heatwaves will get even worse as the planet warms further.

Scientists have found that climate change played a major role in recent heatwaves: the chance of extreme heat at the levels seen in northern Europe in 2018 has doubled; the “Lucifer” heatwave in Europe’s Mediterranean region during summer of 2017 is four times more likely to occur; and the scorching 2016-2017 summer in New South Wales, Australia, was made at least 50 times more likely.

The new study, published on January 11th, 2019 in Nature Communications, shows the growing threat of heatwaves in a warming world, especially for less developed nations. In fact, the researchers found that less developed countries will likely be more affected by heatwaves in a 1.5°C (2.7°F) warmer world than developed countries will be in a 2°C (3.6°F) warmer world.

Year in Review: 18 numbers that tell 2018’s story of the environment, health, and climate

2018 brought with it a torrent of stories that now shape the world we live in and will shape 2019 and years to come.

From a disgraced EPA Administrator, to urgent reports on climate change, the year showed how far we’ve come and how much work remains—especially as President Trump and his administration continue to assault safeguards and deny the reality of a warming world.

Here, we recap the 18 numbers that encapsulate the year that was, and what we’ll be keeping a close eye on in the year to come.

  1. Public Health Threat #1: Acting EPA Administrator Andrew Wheeler. Former coal lobbyist Wheeler took the reins after the end of Scott Pruitt’s destructive tenure, and picked up right where Pruitt left off. Since then, Wheeler has targeted several foundational health and environmental safeguards. It’s now expected that Wheeler will be nominated for the post permanently. Keep reading to see how dangerous that could be to the American people and our planet.
  2. Two mothers who lost their sons because of exposure to methylene chloride, a dangerous chemical in common paint strippers, met with Pruitt and members of Congress from both parties. These moms asked EPA to support a ban on consumer and most commercial uses of methylene chloride. Over 6 months ago, Pruitt said he’d do so, but no action has been taken since.
  3. As for other chemicals the Trump EPA is flouting 2016’s Toxic Substance Control Act amendments, allowing potentially dangerous chemicals into the marketplace and consumers’ homes. Here are three examples.
  4. Wheeler is proposing to gut the EPA methane rules, a move that could result in more than 400,000 tons of additional potent methane, even though some leading companies have asked EPA to regulate methane emissions from oil and gas.
  5. Check out this list of five states that took bold action on climate change this year, showing the kinds of common-sense, economic solutions that can be implemented at scale while protecting people, our economy and our environment.
  6. According to the World Health Organization air pollution kills an estimated 600,000 children every year under the age of 15 and accounts for almost 1 in 10 deaths in children under five. The report found links between air pollution and childhood cancers, asthma, pneumonia and other respiratory infections, making it one of the leading threats to child health.
  7. It’s not all doom and gloom. Prompted by the urgency to act on climate and the advancement of affordable, renewable energy technologies, we’ve seen seven signs that the global energy economy is in transition.
  8. Eight hurricanes formed in Atlantic waters this year, two of which—Hurricanes Florence and Michael—devastated states across the Mid-Atlantic and Southeast. These kinds of super storms are becoming more powerful—and more destructive—due to warmer water, higher seas, shifting weather patterns and increased moisture in the air.
  9. On the other side of the country, California saw wildfires ravage the state, destroying entire towns and killing scores. In total, the fires are expected to cost insurers more than $9 billion and signal the kind of climate dangers the world could face more regularly if greenhouse gases are allowed to pollute our air unchecked.
  10. Might that have something to do with the fact that fossil fuel industries outspent clean energy advocates on climate lobbying by a startling 10 to 1?
  11. By EPA’s own calculations, the Mercury and Air Toxic Standards prevent as many as 11,000 deaths per year, yet the Administration reportedly wants to undercut the rule anyway, with a proposal expected imminently.
  12. A concentrated effort by the oil industry to fight back against clean car standards resulted in more than a quarter of the 12,000 “public” comments submitted to the federal register reflecting the language written by a pro-industry group. Marathon Petroleum, the country’s largest refiner, lobbyists for Exxon Mobil, Chevron, and Phillips 66, joined a network funded by the Koch Brothers network in a massive effort to fight standards that would reduce pollution from vehicles and save Americans money at the gas pump.
  13. The National Climate Assessment, issued by 13 federal agencies, sounded the alarm on the impacts America stands to suffer from climate change, yet went largely ignored by the Trump Administration, which has chosen to side with special interests and industry allies.
  14. 414 investors across the globe—with $31 trillion under management—called for governments to take serious steps to curb climate pollution, citing the “ambition gap” between government commitments and what is needed to sufficiently prevent the world from reaching warming of 2 degrees Celsius above pre-industrial levels.
  15. 2015 saw the adoption of the landmark Paris Agreement, setting nations on a hopeful path toward emissions reduction. Since then, the leadership once shown by America in critical climate talks has been abdicated, left vacant by an administration that chooses to cover its ears and place the world’s children and grandchildren at risk. This year’s climate summit, COP24, saw the creation of a “rule book” to implement the Paris agreement, but also showed that much more needs to be done.
  16. A letter sent by coal baron Robert E. Murray to Vice President Mike Pence listed 16 wishes that the administration has largely taken up as policy. Several among them have led the administration to foolishly attempt to prop up the coal industry despite economic signals diminishing coal’s viability, not to mention its severe health and environmental effects.
  17. After 17 months of countless scandals and reckless attempts to assault bedrock environmental protections, Scott Pruitt resigned his post as EPA Administrator. This list could extend dozens of items longer if we were to count Pruitt’s many offenses. American families and children will not miss him.
  18. A cheery and hopeful note as we head toward the new year: 2018’s midterms saw a wave of pro-environment and climate candidates elected to office across the country. Those candidates-elect—ranging from governors and representatives, to mayors and councilwomen—are leading a charge toward ambitious climate action.

Seis aportes del nuevo informe sobre el clima

Co-escrito por Ilissa Ocko.

Los efectos tangibles del cambio climático provocado por el hombre son cada vez más visibles. Un estudio reciente, encontró por ejemplo, que la temporada de huracanes 2017 fue más intensa como resultado de nuestro clima cambiante. Limitar los niveles de calentamiento global es esencial para frenar los impactos futuros del cambio climático, pero ¿en qué medida un calentamiento adicional de 0,5 ° C cambia nuestro mundo

El informe especial emitido anoche por el Panel Intergubernamental sobre el Cambio Climático (IPCC), considera los impactos del calentamiento global de 1.5 ° C por encima de los niveles preindustriales, en contraste con los 2 ° C, y cómo puede alcanzarse este objetivo de calentamiento inferior. El informe fue escrito por cientos de científicos provenientes de 40 países diferentes y basado en investigaciones de miles de estudios científicos

Aquí hay 6 puntos clave del nuevo informe del IPCC:

  1. Cuando se trata de calentamiento, 1.5 ° C es mucho más seguro que 2 ° C … pero aún más riesgoso que el presente.
