At the Garrison Institute's 2011 Climate, Mind and Behavior Symposium, Renee Lertzman discussed the importance of emotional, affective, and unconscious dimensions in climate change communication and outreach strategy.

This discussion was part of the Institute's Climate, Mind & Behavior Initiative.

In a May 31, 2014 address, President Obama highlighted new Environmental Protection Agency (EPA) actions to reduce carbon pollution. This plan builds on existing efforts by states, cities, and companies. For details on Carbon Pollution Standards, see here.

These efforts align with his long-standing commitment to climate action. As President-elect, Obama pledged "a new chapter of American leadership on climate change" at the November 2008 Global Climate Summit. View his 2008 speech here.

He further addressed climate change during the 2009 Copenhagen Climate Talks and again in June 2013. See his 2009 remarks here and 2013 speech here.

Tom Steyer, co-founder of Advanced Energy Economy (AEE), discusses why advanced energy is a critical issue for the United States. Steyer, who founded Farallon Capital Management before resigning in 2012, has since focused on climate activism.

In 2013, Steyer established NextGen Climate to support climate change activism and completed his personal divestment from fossil fuels. For more information on the Advanced Energy Economy, visit the AEE website.

This discussion was published on August 26, 2013.

On May 6, 2014, President Obama's Science Advisor, Dr. John Holdren, discussed the immediate and future impacts of climate change on Earth's resources.

Kelly Matheson, representing WITNESS, delivers a talk on atmospheric trust litigation (ATL) and the fundamental right to a sustainable living environment. Her presentation highlights critical legal approaches to climate change.

Through compelling personal stories and illustrative videos, Matheson vividly demonstrates how climate change profoundly affects young people globally. This talk was originally published on August 2, 2012.

Eco Eye Series 12, Episode 3, hosted by Duncan Stewart, investigates climate change.

Published on January 21, 2014, this episode examines Ireland's recent extreme weather, including record freezing temperatures, heatwaves, and the worst flooding in 800 years, which left 50,000 homes uninsured. It questions if our climate is changing and discusses the potential impacts both domestically and internationally.

The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for climate change assessment. Established in 1988 by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO), its mission is to provide a clear scientific view on climate change and its potential environmental and socio-economic impacts. The UN General Assembly endorsed its formation.

The IPCC's Fifth Assessment Report, "Climate Change 2014: Impacts, Adaptation, and Vulnerability," was published on March 31, 2014.

In 2003, following "Earth From Above," Yann Arthus-Bertrand, with Sibylle d'Orgeval and Baptiste Rouget-Luchaire, launched the 7 Billion Others project. Twenty directors filmed 6,000 interviews in 84 countries, asking people—from a Brazilian fisherman to a Chinese shopkeeper, a German artist to an Afghan farmer—the same questions about their fears, dreams, trials, and hopes. Questions included: "What have you learned from your parents?", "What do you wish to pass on to your children?", "What trials have you faced?", and "What does love mean to you?"

This visualization illustrates the rise in global temperatures from 1880 through the end of 2013. NASA scientists report that 2013 tied for the seventh warmest year since 1880, continuing a significant long-term warming trend. Notably, with the exception of 1998, the ten warmest years on record have all occurred since 2000, with 2010 and 2005 ranking as the hottest.

The visualization displays a running five-year average global temperature, compared to a 1951-1980 baseline. A color-coded map shows surface temperature anomalies, with red indicating higher and blue indicating lower than normal temperatures. Credits include Animator Lori Perkins, Producer Leslie McCarthy, and Scientists James Hansen Ph.D. and Patrick Lynch.

Climate scientists Kevin Anderson and Alice Bows-Larkin propose a radical de-growth strategy to address climate change. They argue that current solutions by world leaders are insufficient to prevent "runaway global warming," necessitating a fundamental shift in the economic system.

Interviewed by Amy Goodman at the UN Climate Summit in Warsaw, Anderson and Bows-Larkin are from England's influential Tyndall Centre for Climate Change Research.

David Ritter, CEO of Greenpeace Australia Pacific, emphasizes the crucial role of online participation in addressing corporate power. He specifically highlights actions involving Coca-Cola and Nestle.

Ritter asserts, "We are not a pop drink democracy," underscoring the need for public engagement against corporate influence. This discussion was published on June 14, 2013.

Published November 19, 2013, this data visualization illustrates climate change effects. It was produced by the International Geosphere-Biosphere Programme and Globaia, with funding from the UN Foundation.

The visualization summarizes key findings from the Intergovernmental Panel on Climate Change's (IPCC) Fifth Assessment Report (Working Group I summary for policymakers, Physical Science Basis). All presented facts are directly derived from the IPCC summary.

Jeffrey Sachs delivered the keynote at the 2013 Global Grand Challenges Summit in London, focusing on sustainable development. He highlighted that countries are not adequately addressing energy and economic needs to achieve sustainability. This presentation was published on March 30, 2013.

In an October 15, 2013 Financial Times article, responding to Typhoon Haiyan, Sachs emphasized the urgent need for credible, long-term low-carbon energy plans. He outlined four key pillars for a sustainable pathway: increasing low-carbon electricity, electrifying sectors like transport and heating, improving energy efficiency, and ending deforestation.

Have burning questions about Earth's changing climate? Wonder how scientists differentiate human impact from natural causes? Now's your chance to ask a NASA climate scientist directly.

Submit your question by recording a 10-15 second video and uploading it to YouTube, or simply post it on Twitter. Ensure you tag your submission with #askclimate so we can find it.

NASA scientists will record video responses to selected questions, which will be posted on the NASAExplorer YouTube channel.

During NASA's #askclimate campaign, a Twitter user posed a question to Goddard Space Flight Center's Molly Brown: "Will climate change drastically reduce our food production, or will it change what we produce?"

For further details on climate variability and food production, explore NASA's article: Climate Forecasts Warn of Crop Failures.

Studies indicating historical CO2 levels lag behind temperature have merit, confirms Peter Hildebrand, Director of Earth Science at NASA's Goddard Space Flight Center. Responding to a question on Twitter, Hildebrand explained that in the pre-industrial age, temperature changes drove CO2 levels; a warmer climate caused the biosphere to emit more CO2.

However, in the post-industrial era, this dynamic has reversed. Now, increasing atmospheric CO2 is leading to higher temperatures, indicating a fundamental shift in the physical-biological processes. For more information, visit Ask A Climate Scientist.

JPL scientist Josh Willis, from NASA's Ask A Climate Scientist campaign, asserts that global warming is not pausing, despite some decades showing slower surface temperature increases.

Willis points to increased ocean heat trapping and continuously rising sea levels as clear evidence. See [global temperature trends](http://climate.nasa.gov/key_indicators#globalTemp) and [sea level records](http://climate.nasa.gov/key_indicators#seaLevel).

While natural fluctuations occur, human-caused climate change is undeniably progressing. Explore more NASA climate science answers [here](http://bit.ly/1b7rSdL).

In a preview of Moyers & Company, climate expert Anthony Leiserowitz draws an analogy between small shifts in global average temperature and slight changes in human body temperature. He explains that just as a few degrees can signal serious illness, similar small climate shifts can have profound implications.
