Top takeaways from the latest IPCC report

By Ilissa Ocko / Published: April 16, 2014

Yesterday, the United Nations’ Intergovernmental Panel on Climate Change (IPCC) released its last report in a three-part series that makes up the fifth assessment report (AR5) on the latest data and research on climate change. The reports have been issued approximately every five years since 1990.

This latest round of reports began in September 2013 with anupdate on the latest science behind climate change (known as Working Group I). Last month, the second report was released and discussed climate change impacts, adaptation, and vulnerability already observed and projected in the future (known as Working Group II).

The new report released yesterday (known as Working Group III) discusses actions to limit the magnitude and rate of climate change, termed mitigation. Over 400 experts from over 50 countries were involved in the development of the report, which was accepted by representatives from 195 nations.

Here are 5 key findings from the new lPCC report:

1. Global emissions of heat-trapping gases from human activities have continued to rise. Emissions are dominated by carbon dioxide (mainly from fossil fuel combustion and industrial processes), which account for 78% of total greenhouse gas emissions from 1970 to 2010 (when other gas emissions are weighted to incorporate warming capability relative to CO2). Greenhouse gas emissions have grown more rapidly between 2000 and 2010 than in previous decades despite a recent push to limit emissions; economic and population growth are driving these increases and continue to outgrow emission savings from energy improvements.

2. Action to limit the magnitude and rate of climate change is needed immediately. Climate conditions are changing rapidly as shown in Working Group I, and the impacts to society and ecosystems are unequivocal, consequential, and increasing as shown in Working Group II. Scenarios to limit warming to 2ºC (3.6ºF) relative to preindustrial levels require drastic cuts in greenhouse gas emissions by mid-century through large-scale changes in energy systems and land-use practices. The longer we delay action, the more expensive it will be.

3. It is key to reduce energy demand, deploy low-carbon technologies, and better conserve and manage forestry and agriculture. There is a range of technological and behavioral options for sustainable climate actions; nearly one thousand scenarios were analyzed in the report.

  • Near-term reductions in energy demand through efficiency enhancements in transport, buildings, and industry sectors are cost-effective, provide flexibility for decarbonizing in the energy supply sector, reduce risks in energy supply, and prevent future lock-in to carbon-intensive infrastructures.
  • Behavioral and lifestyle changes—such as lower energy use in households, buying longer-lasting products, changing dietary habits, and reducing food waste—can considerably lower greenhouse gas emissions alongside technological and structural changes. Further development and implementation of low-carbon energy and/or carbon removal technologies is important.
  • Renewable energy technologies—such as wind, hydro, and solar power—have finally achieved a level of maturity to enable large-scale deployment. However, steep challenges exist, including varying costs, regional circumstances, and the existing background energy system.
  • The best climate actions for forestry include afforestation, sustainable forest management, and reducing deforestation. For agriculture, best practices include cropland and grazing land management, and restoration of organic soil. Sustainable agriculture practices can also promote resilience to climate change impacts.

4. Effective actions will only be achieved by international cooperation. Climate change is a global problem because most heat-trapping gases accumulate over time and mix globally. Therefore, emissions by an individual, community, company, or country, affect the globe. The number of institutions for international cooperation is increasing, and sharing knowledge and technologies with other nations speeds up finding solutions. The issue is complicated by the fact that different countries’ past and future contributions to atmospheric greenhouse gas levels are different, as is their capacities to implement actions to limit climate change and build resilience.

5. Co-benefits strengthen the basis for undertaking climate action. Measures to limit energy demand (efficiency, conservation, and behavioral changes) and renewable alternatives can reduce the risk of energy supply, improve public health and the environment by limiting pollution, induce local and sectoral employment gains, support good business practices, improve security of energy supply at the national level, and eradicate poverty. Adverse side effects, such as reduced revenue from coal and oil exporters, can be to a certain extent avoided by the development of carbon capture and storage technologies.

The IPCC will conclude the AR5 in October 2014 with a final report that summarizes the three-part series, recapping the major findings of the physical science of climate change, its effects on society and ecosystems, and actions to avert catastrophic climate change.

There are many ways YOU can help promote climate actions, such as supporting the U.S. to continue its emission-reducing efforts like the EPA’s power plant standards.

What the growing Latino community can do for climate politics

By Lucía Oliva Hennelly / Published: April 9, 2014

(This post originally appeared on EDF Voices. Para leer in Espanol haga clic aquí)

In 2012 Latinos made up 1 in 10 voters and helped decide the Presidential election with record-setting voter margins. Last month in California, the most populous state in the nation, the Hispanic population surpassed that of non-Hispanic whites. The only other state to reach this benchmark is New Mexico, where the Latino population is almost 10% larger than that of non-Hispanic whites.

As the Latino population continues to grow across the country, so does its influence in key political arenas. In battleground states like Florida, Colorado, and Nevada, Latinos accounted for 17, 14, and 18 percent of voters in 2012, respectively, an increase from previous elections. The trend has reignited a lively discussion about the influence of the American Latino community, the “sleeping giant” of American politics.

There’s also a lesser-known political trend that is emerging among the country’s youngest and fastest-growing demographic: the demand among Latinos for action to address climate change. In a new national poll released last month by the Natural Resources Defense Council and Latino Decisions:

  • 9 out of 10 Latino voters “want the government to take action against the dangers of global warming and climate change”
  • 8 in 10 Latinos want the President to curb the carbon pollution that causes climate change
  • 86% of Latinos support limits on carbon pollution from power plants

How is this demographic shift significant to environmental advocacy?

The implications of this demographic moving so clearly in favor of pro-environmental policies is significant. For one, environmental policy issues are likely to fast become determining issues for Latino voters on both sides of the aisle. According to Latino Decisions, a leader in Latino political opinion research, the only other policy issue that has received such high levels of support is immigration reform, an issue in the lead among the most significant deciding issues for Latino voters across the political spectrum.

This demographic shift is also significant as the impacts of climate change become more severe. In recent months, key electoral states with large Latino populations have felt the devastating effects of climate change, from the unprecedented flooding in Colorado to California’s historic drought. With 50,000 Latinos turning 18 every month, a solid stance on environmental policy may fast become a make or break issue for elected officials in these states and at the national level.

Combined, these trends paint a clear picture, one of a Latino population that disproportionately supports action on climate change and that is increasingly influential in key political states.

Environmentalists, take note: this is a major opportunityfor the environmental movement to move forward policy that has stalled in the past. Equally as urgent, it is a tremendous opportunity to elevate the voices of Latinos, among other communities of color, disproportionately affected by environmental issues. A few examples:

  • It’s a chance to build support for green jobs initiatives, many of which will be undertaken by Latinos and Latinas
  • It’s a call to arms to better address the environmental health impacts that disproportionately affect Latino communities

Perhaps most important, it’s an open door to create more space for diversity in a movement that needs broader support to succeed, and one that will be more effective by better engaging underrepresented communities. How well we do this will be a measure of how quickly and how equitably we hope to meaningfully address climate change, the defining issue of our time.

Lo que la creciente comunidad latina podría lograr para las políticas del cambio climático

By Lucía Oliva Hennelly / Published: April 6, 2014

En el 2012, los latinos fueron 1 de cada 10 votantes y ayudaron a decidir las elecciones presidenciales, estableciendo un margen récord de votantes.  El mes pasado en California, el estado más populoso de Estados Unidos, la población hispana sobrepasó la de blancos no hispanos.   El único otro estado a llegar a este punto es Nuevo México, cuya población hispana-latina es casi un diez por ciento mayor que la de blancos no hispanos.

Así como la población latina continúa a crecer en todo el país, así crece su influencia en áreas de política claves.  En aquellos estados que son campos de batalla de las elecciones, como Florida, Colorado y Nevada, los latinos representaron el 17, 14 y 18 por ciento de votantes en el 2012, respectivamente, lo que refleja un aumento con relación a elecciones anteriores.  La tendencia ha reavivado una animada discusión sobre la influencia de la comunidad latina estadounidense, el “gigante dormido” en la política del país.

También hay una tendencia política menos reconocida que está surgiendo entre los grupos más jóvenes y de más rápido crecimiento: la demanda entre latinos para actuar con el fin de hacerle frente al cambio climático.  Según una nueva encuesta nacional publicada el mes pasado por Natural Resources Defense Council y Latino Decisions: Read More »

IPCC: Cutting pollution isn’t enough – we need smart adaptation, too

By Rebecca Shaw / Published: April 2, 2014

(This post originally appeared on EDF Voices)

Rebecca Shaw is a member of the Intergovernmental Panel on Climate Change (IPCC) and a lead author on Chapter 16, “Adaptation, Opportunities, Constraints and Limits,” of Working Group 2, Fifth Assessment Report. She is also a contributing author for the chapter, “Terrestrial Ecosystems and Inland Waters Systems,” and an author on the technical summary.

Today, the Intergovernmental Panel on Climate Change released its 2014 report on impacts, vulnerability and adaptation.

There are three top take-a-ways from the report:

  1. The documented impacts of climate change are widespread, unequivocal and consequential across the planet for both people and nature
  2. Confronting climate change is now an issue of managing risks, and those risks are greater if we continue to pollute the atmosphere.
  3. To protect ourselves from the impacts of climate change that can’t be avoided, we must make smart adaptation investments in our cities, working lands and ecosystems now. These investments will increase resilience in the face of climate change and lead to a more vibrant and secure world.

The report contains extensive documentation on the impacts the warming atmosphere is already having on agriculture, coastal communities, terrestrial and marine plants and animals, and fresh water availability. Impacts from recent extreme climatic events such as heat waves, droughts, floods and wildfires demonstrate the significant vulnerability of some ecosystems and humans systems. Poor and impoverished communities will be most vulnerable, as will species lacking the robust ability to adapt to climate change.

And the science clearly shows that rates of annual crop yield increases are slowing. Climate change acts as an anchor on production – a heavy weight that will grow heavier each year climate change proceeds unchecked and unmitigated.

As climate change impacts increase, so does the need for getting smart about cutting carbon pollution. It is equally urgent that we super charge efforts to manage the risks associated with the impacts we cannot avoid. It’s not a choice between mitigation and adaptation anymore – we need both, fast. Without action, the magnitude and rates of climate change will lead to high risk of abrupt and irreversible change in terrestrial and freshwater ecosystems. And it will pose major challenges to cities, farms and infrastructure.

Yet, there is some hope. And this is where the new report departs from the 2007 IPCC report. We found that individuals, communities, businesses and governments around the world are innovating adaptation actions, plans and policies.

Here at EDF, we’re investing in transformational adaptation projects that will ensure that people and nature will be more resilient in the face of climate change:

  • In the Mississippi River Delta we are harnessing the river’s natural processes to rebuild coastal wetlands to protect coastal communities from sea level rise and extreme weather.
  • In the drought-stricken Colorado River Basin, we’ve helped to develop water-sharing agreements that can be replicated in other water-stressed regions.
  • Across the Western U.S., we are implementing habitat-exchange programs that will dynamically protect threatened wildlife populations for the long-term, even as their ranges shift.
  • And in the Midwest, we’re working with farmers to decrease greenhouse gas pollution caused by overuse of fertilizer on crops.

These examples are demonstrating that as long as smart investments in adaptation measures are taken in concert with substantial cuts in carbon pollution, we have an opportunity to decrease our vulnerability to climate change and to build a more vibrant and secure world for all.

6 key insights from the latest IPCC climate report

By Ilissa Ocko / Published: April 1, 2014

(This post originally appeared on EDF Voices)

Since 1990, the United Nations’ Intergovernmental Panel on Climate Change (IPCC) has released a series of reports that assess the latest data and research on climate change.

The reports are issued approximately every five years. In September 2013, the IPCC issued its newest round of reports by sharing the latest science, concluding with more confidence than ever that humans are responsible and that weather will likely get even more extreme, along with many other key findings.

The newest report, released today, looks at impacts, adaptation and vulnerability. Next month comes the thirdreport in the 3-part series that makes up the IPCC’s 5thAssessment Report (IPCC AR5); it focuses on mitigation—that is, actions to limit the magnitude and rate of climate change.

Over 600 scientists and experts from at least 70 countries were involved in writing this latest installment of the IPCC AR5, which is referred to as Working Group II. Representatives from 195 nations had to approve of the Summary for Policymakers document line-by-line.

The report’s content focuses on three topics:

  • Impacts: effects of climate change on people, society, and ecosystems
  • Adaptation: actions to limit our risks to climate change
  • Vulnerability: the susceptibility of the human and natural worlds to climate change

Here are six key findings from the new IPCC report:

1.       Climate change is now everywhere. Impacts have been found on every continent and across all oceans. Both human and natural systems are experiencing the far-reaching and ever-growing effects: water resources are shrinking; terrestrial, freshwater, and marine species have changed their ways of life; major crop yields have decreased; and heat-related deaths have risen.

2.       Humans and ecosystems are both vulnerable. Climate events such as heat waves, droughts, floods, and wildfires alter ecosystems; disrupt food production and water supply; damage infrastructure and settlements; cause sickness and mortality; and adversely affect mental health and human livelihood. However, people who are socially, economically, culturally, politically, institutionally, or otherwise marginalized are especially vulnerable.

3.       Food security, water resources, human health, ecosystems, and the economy are all at stake. While the degree of risks varies based on climatic and non-climatic factors, scientists are confident that human and natural systems are threatened with continued warming. ‘Runaway’ warming (a global temperature increase of 4˚C (7.2˚F) above preindustrial levels—we are currently at 0.86˚C (1.5˚F)) could make normal activities like growing food or working outdoors impossible in many regions.

4.       Many global risks of climate change are concentrated in urban areas. Heat stress, extreme precipitation, inland and coastal flooding, landslides, air pollution, drought, and water scarcity pose risks in urban areas for people, assets, economies, and ecosystems.

5.       Building resilience is critical to limiting risks… Even the most rigorous mitigation tactics still won’t eliminate some additional warming. The upshot: there are countless opportunities for local, state, and national governments to plan and implement adaptation efforts, and also opportunities for public and private engagements. The down side: several barriers to adaptation still exist (such as legal and financial constraints), and if heat-trapping gas emissions remain unabated and the Earth warms by 4˚C (7.2˚F), the impacts may grow larger than our capacity to adapt.

6.       …but cutting heat-trapping gas emissions is essential. Delaying mitigation actions will likely reduce options for climate-resilient pathways, and make them much less affordable. Fortunately, we can solve two problems at once; examples of actions that build resilience and cut gas emissions include: improved energy efficiency and cleaner energy sources; reduced energy and water consumption in urban areas through greening cities and recycling water; sustainable agriculture and forestry; and protection of ecosystems for carbon storage and other ecosystem services.

The Supreme Court and Climate Pollution: What is – and is not — at stake

By Vickie Patton / Published: February 24, 2014

(This post originally appeared on EDF Voices)

Today, the Supreme Court will hear oral argument in a case challenging EPA’s interpretation that the Clean Air Act permit program requiring new and rebuilt industrial sources to deploy leading pollution control technology for each pollutant subject to regulation under the Act applies to greenhouse gases, just as these requirements have limited other airborne contaminants for over three decades.

The case is Utility Air Regulatory Group v. EPA (No. 12-1146). 

What’s at stake: Innovation in Addressing Climate Pollution and Clearing the Air about Climate Obstructionism

This case is remarkable for what is not at stake, as well as for what is.

While the Supreme Court is considering only a single legal question of the numerous issues that were raised, this case has important implications.

Exempting climate pollution from these specific provisions of the Clean Air Act would harm innovation, because they were carefully designed by Congress to spur the development of new pollution prevention and control techniques for industrial sources. Putting a stop to these legislatively-crafted incentives to innovation in precisely the area where we so urgently need innovation – in addressing climate-destabilizing pollution — would be a damaging loss and risks “locking in” new high emitting and long lived industrial infrastructure. Such an exemption for climate pollution is patently contrary to Congress’s specific command, in the statutory provisions at issue here, that these innovation-spurring requirements apply to “each pollutant subject to regulation under the Act”.

Climate obstructionists will undoubtedly twist the meaning of the case to suggest broader implications, despite the court’s decision to review only one narrow question. While the Administration is judiciously carrying out its responsibilities under the Clean Air Act to address climate pollution – in accordance with the authority that was twice affirmed by the United States Supreme Court — climate obstructionists will use this case to sow havoc and attack the U.S. Environmental Protection Agency. Indeed, these forces have already attacked EPA by unsuccessfully litigating virtually every aspect of EPA’s first generation climate protections in court over a span of many years. Unfortunately, they will continue to attack EPA in the public square invoking the polarizing rhetoric that most Americans associate with divisive Beltway politics – not real world solutions.

What is not at stake in this case is the EPA’s determination that six greenhouse gases –carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride –endanger the health and welfare of current and future generations. This is the bedrock for EPA’s manifest authority to adopt climate protections for cleaner cars and cleaner freight trucks, for reducing the potent methane leaked and vented from oil and gas development activities in the same way that Colorado has adopted methane emissions standards, and for cutting the massive carbon pollution from power plants — the nation’s single largest source of carbon pollution and one of the largest in the world.

The history behind the case

For the past four years, big polluters and litigants such as the Attorney General of Texas have been suing the U.S. Environmental Protection Agency over all aspects of EPA’s climate protections for America – including the science-based endangerment finding, and the historic Clean Cars Standards that are saving Americans money at the gas pump while strengthening our nation’s energy security and reducing pollution. By contrast, the U.S. Automakers have consistently supported the clean car standards.

These dozens of lawsuits were considered together by the U.S. Court of Appeals for the D.C. Circuit – which upheld EPA’s climate protections and rejected the legal challenges. In 2012, a three Judge panel of that court held that EPA’s interpretation of the Clean Air Act was “unambiguously correct.” Then-Chief Judge David Sentelle, appointed to the Court by President Ronald Regan, was a member of the three Judge panel that unanimously affirmed EPA’s action.

Opponents filed numerous petitions seeking review by the Supreme Court, which refused to entertain most of their challenges.

Instead, the Court granted review of a single question – whether, under the terms of the Clean Air Act, EPA’s regulation of climate pollution from cars triggered the requirement for pre-construction permits limiting the climate pollution discharged by large, new and rebuilt industrial sources of that pollution in the same way these requirements have applied to other air pollutants from these sources for over 35 years.

Bottom line

We need all available safeguards under the Clean Air Act to address the urgent challenge of climate change – including the advanced pollution control measures required as an essential protection in construction permits for large industrial sources. These measures are vital if we hope to minimize industrial climate pollution.

Further, one of the principal legal theories being advanced by petitioners would have adverse consequences for EPA’s long-standing interpretation of the law – spanning the Presidencies of Ronald Regan, George H.W. Bush and George W. Bush – that has expansively applied the protections of the Clean Air Act’s pre-construction review permit program to all regulated air pollutants. This line of attack, designed to narrow the air pollutants subject to these limits, would call into question the application of the program to pollutants such as hydrogen sulfide, fluorides and sulfuric acid mist.

Finally, we need to tell the truth to the public, to policymakers and to the highest Court in the land that EPA is judiciously carrying out its responsibilities under the nation’s clean air laws to protect human health and the environment from climate pollution. We must take a stand against the sharply polarizing rhetorical excess leveled at EPA. For the real world solutions that have won far reaching support, look no further than the cleaner cars on the road today that are strengthening our energy security, saving families hard earned money at the gas pump, and cutting carbon pollution.

This is why EDF will be at the Supreme Court today.

Editor’s Note: Environmental Defense Fund is a party to the case before the Supreme Court and participated in the presentation of oral arguments when the case was before the U.S. Court of Appeals for the D.C. Circuit.  A coalition of states and NGO allies are also vigorously defending these clean air protections against legal attack — including California, Connecticut, Delaware, Illinois, Iowa, Maine, Maryland, Massachusetts, New Hampshire, New Mexico, New York, Oregon, Rhode Island, Vermont, Washington, and the city of New York.
