2° C or Not 2° C: Insights from the Latest IPCC Climate Report

In his “To Be or Not to Be” soliloquy, Shakespeare’s Hamlet eloquently presents each of us with an opportunity to wrestle with the timeless question of how to respond to the slings and arrows of life’s outrageous fortunes.

With today’s release of the Summary for Policymakers of Working Group I:  The Physical Science Basis, the Intergovernmental Panel on Climate Change’s (IPCC) Fifth Assessment Report (AR5) presents us with a very different opportunity to wrestle with our collective response to the slings and arrows of unabated carbon emissions on our warming planet. To be sure, the formal language of the IPCC is far less eloquent than Shakespeare’s, but the authoritative and cautiously-written climate science synthesis provokes us to confront profoundly important questions – questions that are hugely time-sensitive, not timeless.

Managing Risk in Ohio: Clean Energy’s Role in a Reliable, Diverse Power Supply

“Don’t put all your eggs in one basket” is a mantra often used by investors who diversify their portfolios to protect against volatility in financial markets. It’s also appropriate for the electricity sector in Ohio, a state that has historically been overdependent on coal and is fast becoming over reliant on both coal and natural gas, leaving consumers vulnerable to volatility in energy markets and many other risks. Renewable energy and energy efficiency can help diversify Ohio’s power mix, and bring safe, clean, reliable, and affordable power to consumers, according to a new UCS report. Why then is the central policy that is successfully supporting these clean energy industries in Ohio under attack? Read More

Five Reasons Why Sea Ice Decline Should be Front Page News

In the next few days the Arctic sea ice will reach its minimum extent for 2013. At the end of this year’s summer melt season, the areal extent covered by sea ice was more than a million square kilometers below the 30-year average. That’s a lot of ice missing compared to an average year. An area of frozen ocean—ten times the size of Indiana, or four times the size of Colorado, or a third bigger than Texas—is just not there this summer. Read More

The Intergovernmental Panel on Climate Change (IPCC) has established a strong track record for projecting the future consequences of climate change. Though the process for producing the report can seem opaque from the outside, we can put great confidence in the body’s findings. Read More

Wacky Weather, a Warmer Arctic, and a Slower Jet Stream – Is There a Link?

The flow of the jet stream is somewhat like a river – at times, a straight rushing ravine and at other times, a slow twisting meander. It’s almost like the atmosphere is alternately dancing the quickstep or doing a slow waltz. Why does the jet stream change its behavior and how might a warming climate be affecting this central influence on our weather in the U.S.? Let’s take a close look at what’s going on in the atmosphere up above us every day. Read More

Koch-Funded Group Misleads Georgia on Solar

UPDATE, July 11: GA Regulators vote 4- 1 for more solar. We describe how to keep rates low in our update at the bottom of the page.

The Georgia Public Service Commission (PSC) will vote this week on a new proposal requiring Georgia Power, the state’s largest utility, to use more solar energy.

It’s a nonpartisan plan supported by the Atlanta Tea Party Patriots as a way to diversify the state’s energy portfolio and save consumers money.  Read More

The President Touts Natural Gas as an Important Climate Solution: How Far Can it Take Us?

The President’s climate plan is an important start for reducing carbon and other heat-trapping emissions from human activities that are driving climate change. One of the key components of his plan is directing the EPA to complete carbon standards for new and existing power plants, which could help transition the power sector away from coal to natural gas and other cleaner sources like renewable energy and energy efficiency.

Today’s “King Tides” Preview the Future of Sea Level Rise

If you’ve been wondering what sea level will look like with ongoing climate change, head to the coast during a “king tide,” the highest tide of the year. This weekend extreme high tides are happening in a number of places along the U.S. East Coast, including Florida, New Jersey, and Maryland. Grab your camera and join the fray! Read More

Scientists Agree Human-Caused Climate Change is Real: But Wait, We’ve Known That for Decades!

An important peer-reviewed study was published today by John Cook et al. in the journal Environmental Research Letters. John Cook runs the well-known Skeptical Science website that rebuts global warming misinformation. His new research once again confirms there is overwhelming agreement amongst climate scientists – over 97 percent agree – and in the scientific literature – over 97 percent of papers confirm – that global warming is real and largely caused by humans. However, current surveys of the U.S. public, such as those done by the Pew Center and Yale, show that less than half the population believe scientists are in agreement on the issue of human-caused climate change.
