EarthTalk: Climate Change and Extreme Weather

In a poll conducted by Yale University, four out of five Americans reported personally experiencing one or more types of extreme weather in 2011, while more than a third said they were personally harmed by one or more of these events. A large majority of Americans believe that global warming made several high profile extreme weather events worseEarthTalk® is a weekly environmental column made available to our readers from the editors of E/The Environmental Magazine

Dear EarthTalk: What is the scientific consensus on all the extreme weather we’ve been having—from monster tornadoes to massive floods and wildfires? Is there a clear connection to climate change? And if so what are we doing to be prepared?   - Jason Devine, Summit, PA

Extreme weather does not prove the existence of global warming, but climate change is likely to exaggerate it—by messing with ocean currents, providing extra heat to forming tornadoes, bolstering heat waves, lengthening droughts and causing more precipitation and flooding.

“A changing climate leads to changes in the frequency, intensity, spatial extent, duration and timing of extreme weather and climate events, and can result in unprecedented extreme weather and climate events,” reports the Intergovernmental Panel on Climate Change (IPCC), an independent group of leading climate scientists convened by the United Nations to provide the world with a clear scientific view on the current state of knowledge in climate change and its potential environmental and socio-economic impacts.

New CDP Report Points to the Growth of Corporate Sustainability

Companies begin to see sustainability efforts as key to their bottom lineThe CDP Global 500 Climate Change Report 2012 indicates that there has been an increase in corporate sustainability around the world. The CDP assesses corporate risks and opportunities on behalf of 655 institutional investors with $78 trillion in assets. The CDP harnesses the power of market forces to collect information from companies about their GHG emissions, water usage and other environmental impacts. The CDP has assembled the world’s largest collection of primary data on climate change and water. They use this data to help businesses develop strategies, make investments and craft policy.

The CDP are powerful advocates of transparency in environmental reporting and they champion corporate strategies designed to reduce CO2 and conserve water. The CDP is an international, not-for-profit organization providing the only global system for companies and cities to measure, disclose, manage and share vital environmental information. The 2012 CDP Global 500 Climate Change report was co-written with professional services firm PwC.

EarthTalk: Atmospheric CO2 – Is it Too Late Anyway?

The amount of carbon dioxide (CO2) in the atmosphere today is roughly 390 parts per million (ppm), well above the 275 ppm it was before we started pumping pollution skyward during the Industrial Revolution. Climate scientists and green leaders today agree that 350 ppm would be a tolerable upper limit.EarthTalk® is a weekly environmental column made available to our readers from the editors of E/The Environmental Magazine

Dear EarthTalk: I read that CO2 in our atmosphere is now more than 300 parts per million. Doesn’t this mean that we’re too late to avoid the worst impacts of climate change?  – Karl Bren, Richmond, VA

Actually the amount of carbon dioxide (CO2) in the atmosphere today is roughly 390 parts per million (ppm). And that’s not good news. “Experts agree that this level cannot be sustained for many decades without potentially catastrophic consequences,” reports the Geos Institute, an Oregon-based non-profit and consulting firm that uses science to help people predict, reduce and prepare for climate change.

While we’re unlikely to get atmospheric CO2 concentrations down as low as they were (275 ppm) before we started pumping pollution skyward during the Industrial Revolution, climate scientists and green leaders agree that 350 ppm would be a tolerable upper limit. Prior to 2007 scientists weren’t sure what emissions reduction goal to shoot for, but new evidence led researchers to reach consensus on 350 ppm if we wished to have a planet, in the words of NASA climatologist James Hansen, “similar to the one on which civilization developed and to which life on earth is adapted.”

Recommended Video Series: Don’t Just Sit There – Do Something! (about climate change)

Five Common Myths Skeptics Use About Climate Change

I recently discovered a YouTube video series called Don’t Just Sit There Do Something!  The series is produced by Joylette Portlock, a Stanford and MIT-educated scientist, in conjunction with her website DoSomethingAboutClimate.com. Her videos combine information and action tips to help her audience learn about climate change while offering simple action steps individuals can take to do something about it. All with a dash of humor. Good work Joylette!

In the episode below she discusses the top five most common myths from skeptics about climate change.
