Poll Finds Half of Republicans Back Carbon Limits

A poll released in December 2014 from the Associated Press-NORC Center for Public Affairs Research and Yale University show that half of all Republicans said they support regulating carbon dioxide pollution. Read the article.


EPA's Clean Power Plan

The EPA in June 2014 proposed its plan to cut carbon pollution from power plants. The proposal takes into account how states, cities and businesses across the country are aleady addressing climate change risks by taking action. States will have an important role as full partners with the federal government in cutting pollution. EPA's proposal will maintain an affordable, reliable energy system while protecting health and the environment.

EPA is accepting comments until December 19, 2014. Make your voice heard!


Sierra Club Statement on U.S.-China Climate Announcement

On November 11, 2014, the U.S. and China released a groundbreaking announcement to set ambitious goals for climate action and carbon pollution reductions. President Obama has made a pledge for 2025 that keeps the United States on track to cut its carbon pollution by 80 percent by 2050, and setting a high bar for future administrations. And for the first time ever, China committed to peak its carbon emissions by 2030 at the latest.

Michael Brune, Sierra Club Executive Director, released the following statement in response:

“The Sierra Club applauds President Obama and President Xi for setting ambitious goals to reduce dangerous carbon pollution and tackle the climate crisis.

“China's new goal of producing 20 percent of its power from clean energy by 2030 is a huge step forward that signals a historic shift away from dirty fossil fuels, and could drive a new global competition for clean energy technology.

“By setting their sights high, the U.S. and China are showing that they are serious about taking action on the climate crisis and, that together, the international community can beat back climate disruption.”

Iowa Scientists Release 2014 Climate Statement

Iowans are experiencing real impacts from climate change, including heavier rains and increased flooding.  Human health effects from climate change are just as real and are already being felt in Iowa, according to a statement by statewide group of 180 Iowa scientists.

“Climate change is negatively impacting our water quality, increasing exposures to allergens and air pollutants, introducing new infectious diseases, and imposing increased stress on Iowa families,” said Peter Thorne, Professor and Head of the Department of Occupational & Environmental Health, College of Public Health, University of Iowa.

The fourth annual statement, “Iowa Climate Statement 2014: Impacts on the Health of Iowans,” released October 10, 2014, was signed by 180 science faculty and researchers from 38 Iowa colleges and universities.

The scientists say the health‐related effects of extreme weather events are the most obvious, immediate, and direct.  These events are increasing in frequency and severity as our atmosphere warms and holds more moisture.

“Repeated heavy rains increase human exposure to toxic chemicals and raw sewage that are spread by flood waters,” said David Osterberg, Associate Clinical Professor, Department of Occupational and Environmental Health, University of Iowa.

Degraded water quality is also directly associated with climate change.  “In farm states like Iowa, higher water temperatures combine with high nutrient levels to create large harmful algal blooms which make water unsuitable for human and animal consumption and for recreation,” stated Osterberg.

“The strong support for the statement reflects the consensus among Iowa science faculty and research staff that action is needed now to lower emissions and find new ways to adapt to climate changes in order to reduce the risks of new health problems,” stated Dave Courard‐Hauri, Associate Professor, Environmental Science and Policy Program, Drake University.

Climate change is also making it more difficult for many Iowans to breathe.  Plants produce more pollen, pollen that is increasingly potent in response to warmer temperatures and higher carbon dioxide levels in the air.

“The number of Iowans with respiratory problems such as childhood asthma has increased dramatically since the 1980s. In many cases, this is linked to increased exposures to flood molds and to higher indoor moisture, as well as to lung‐damaging ozone and fine particulate matter from burning fossil fuels,” said Thorne.

“New infectious diseases are becoming more common in the Midwest as the organisms that carry them move north due to rising temperatures. Disease carrying mosquitos and ticks are living longer and expanding their range due to increasing temperatures, more rainfall, and longer summers,” said Yogesh Shah, Associate Dean, Department of Global Health, Des Moines University.

“Our changing climate’s influence on mental health is less obvious, but it is well established that thousands of Iowans have been impacted by stress from the loss of homes and income due to climate‐ related flooding and drought,” Mary Mincer Hansen, Adjunct Professor, College of Health Sciences MPH Program, Des Moines University.

“As long as greenhouse gas emissions continue to increase, climate‐related health problems will continue to grow,” said Neil Bernstein, Chair, Department of Natural and Applied Sciences, Mount Mercy University. The scientists agree that adopting strong climate‐change policies will play a vital role in diminishing human suffering and illness now and for generations to come.

“It is clear that expanding energy efficiency and clean renewable energy efforts will have the co‐benefits of reducing air pollution and the creation of additional jobs and economic opportunities for Iowans,” stated Bernstein.

Climate Change Advisory Council Final Report – December 2008


April 2013: Global Temps 13th Highest on Record

Year-to-date eighth warmest period on record; North American snow cover extent third largest on record

The globally-averaged temperature for April 2013 was the 13th warmest April since record keeping began in 1880. April 2013 also marks the 37th consecutive April and 338th consecutive month with a global temperature above the 20th century average.

Many areas of the world experienced higher-than-average monthly temperatures, including southern Europe, central Asia, the Russian Far East, southwestern Australia, southern Argentina, and western Greenland. Meanwhile, most of North America, northern and western Europe, northeastern Asia, central South America, and much of equatorial Africa were notably below average.


65% of Americans support a revenue-neutral carbon tax (Yale/GMU)

Despite persistent concerns about the economy, Americans support a broad range of policies to address climate disruption and expand the nation’s clean energy economy. A Yale University and George Mason University survey finds that 70% of American adults say that “global warming” should be a priority for the President and Congress – including 44% of Republicans, 72% of independents, and 85% of Democrats. Looking ahead to 2012, 52% say that a presidential candidate’s views on “global warming” will be “one of several important issues” in determining their vote. Just 2% say that climate views will be the “single most important issue” in their decision. 66% say that the United States should make a "large-scale effort" (26%) or "medium-scale effort" (40%) to reduce global warming, even if it has large or moderate economic costs. 73% of Americans support regulating carbon dioxide as a pollutant, and 66% support signing an international treaty to cut emissions.

On a bipartisan basis, Americans support the concept of a revenue-neutral carbon tax that includes individual tax breaks. 65% would support "a shift in taxes that reduces the federal income tax that Americans pay each year, but increases taxes on coal, oil, and natural gas by an equal amount." Respondents were told that "this shift would be 'revenue neutral' (meaning the total amount of taxes collected by the government would stay the same), but would help create jobs and decrease pollution."

Whether or not Americans would support a $10/ton tax on fuels that "produce carbon dioxide (coal, oil, natural gas)" depends on what is done with the revenue. Researchers presented respondents with different carbon tax structures, each of which would slightly increase commodity prices. The most popular strategy is to reduce federal income taxes: If revenues are used to reduce federal income taxes, 60% support the carbon tax. If revenues are returned to Americans via an annual check, support drops to 49%. If revenues are used to reduce the national debt, just 44% support the tax. Without explanation of how revenue would be used, just 37% support the carbon tax.

Americans overwhelmingly (90%) believe that developing clean energy sources should be a priority for President Obama and Congress. Despite continued concern about the economy, 78% of Americans support funding renewable energy research, 78% support tax rebates for efficient cars and solar, and 63% support requiring utilities to produce at least 20% of their electricity from renewable sources (even if it costs the average household an extra $100 per year). On the other hand, 69% oppose federal subsidies to the fossil fuel industry, and 54% oppose ethanol subsidies. However, many Americans believe the expansion of offshore drilling is an effective strategy to address our energy needs (63% support expansion), but just 42% support building more nuclear plants.

Finally, this survey found that Americans don’t believe the environment and economy are at odds with one another. 54% of Americans say that protecting the environment "improves economic growth and provides new jobs," 31% say it has no effect, and just 15% believe it "reduces economic growth and costs jobs."

Protecting Americans from Global Warming Pollution
New EPA safeguards to limit global warming pollution will begin moving forward January 2 as planned now that legislative moves to stop the safeguards have been placed on hold. The decision by Sen. Jay Rockefeller (D-WV) to shelve the legislation follows a ruling by a federal appeals court which overturned industry arguments and cleared the way for EPA to protect Americans by taking action on climate change pollution.

Climate Disruption: Is Extreme Weather the New Normal?

In November 2011, the International Panel on Climate Change (IPCC) released a special report examining the link between extreme weather events and global climate change. The report – a culmination of a 2-year process involving 100 scientists and climate policy experts – concludes that climate change is indeed responsible for the rise in number of extreme weather events. IPPC says it is “likely” (a 66% to 100% probability) that the increased frequency of extreme weather events is a result of greenhouse gas emissions from human activity – including coal-fired power plants, fuels burned for transportation, and deforestation. Researchers note that “economic losses from weather- and climate-related disasters are increasing,” and they warn that more extreme weather events are coming our way this century. This year, Americans have endured a record-number of extreme weather events, such as intense summer heat waves, severe droughts in Texas and Oklahoma, and flooding in Mississippi. According to the National Climatic Data Center, extreme weather events in 2011 have already cost the United States over $50 billion in economic damages.

In response to the IPCC report, the Yale Project on Climate Change Communication released new data showing that a majority of Americans believe “global warming” made recent extreme weather events worse. Interestingly, people are most likely to believe that global warming intensified heat waves and droughts. They are less inclined to say that extreme snowfalls or hurricanes were made worse by global warming. I attribute this pattern to Yale’s use of “global warming” instead of “climate change” or (our favorite) “climate disruption.” The term “warming” inherently highlights rising global temperatures and ignores other climate changes (i.e. cold temperatures and more or less precipitation).

On behalf of Yale/GMU, Knowledge Networks interviewed 1,000 adults nationwide from Oct. 20 - Nov. 16; MoE ±3.0% points at 95% CI

This report re-confirms that climate disruption is already happening, and that human activity is playing a role. Scientific evidence is mounting, yet many in Congress continue to deny that climate disruption is happening at all. Talking about the connection between climate and extreme weather can be a pathway to greater public concern and support for climate policies. The scientific evidence is consistent with what people intuitively understand: the changing climate is impacting the weather in our backyards and taking a toll on our pocketbooks. We must demand that our leaders combat climate disruption by moving America beyond dirty fossil fuels and towards a clean energy economy. We simply can’t afford to ignore climate disruption any longer.

The Top Five Things You Need To Know About EPA’s New Carbon Pollution Rule

by David Roberts, ThinkProgress Climate Progress, March 27, 2012

After long anticipation and many delays, EPA is expected to issue its first limits on carbon pollution from power plants this week.

With Republicans increasingly desperate in the face of economic recovery, they are sure to treat this as a lifeline, a focus for renewed attacks. They will try to make the rule a stand-in for government overreach, job-killing regulations, and Obama’s secret plan to raise gas prices. Also probably Sharia.

Climate Regulations a Job Killer? Quit Crying Wolf

by Donald Cohen for YES! Magazine 

July 11, 2011

Over and over, the regulations that the Chamber of Commerce says will be catastrophic have become the basic safeguards we take for granted.

There’s an old adage that if you repeat a lie often enough, people will believe it. That seems to be the unofficial motto of the United States Chamber of Commerce, which has spent the last forty years repeating (and repeating and repeating) the mantra that government regulations on businesses “kill jobs” and economic growth. But their predictions have been repeatedly wrong. The laws they warned would bring economic ruin have become the basic health, safety, and environmental safeguards we now take for granted.
