A Better Answer to Climate Change Is Hidden in the Clouds

Clouds

Climate scientists are studying a bewildering array of changes taking place in the air, on land and in the sea. But where should they concentrate their efforts? First and foremost, it seems, are clouds. Better understanding of how clouds affect global warming, and how airborne particles affect cloud formation, is one of three gaps in [...]

The New Climate Data: So What?

3 sea level

After much anticipation, the Intergovernmental Panel on Climate Change on Friday revealed it’s new assessment of climate change, after two years of deliberation. The bottom line: global temperatures and sea levels will rise even faster than everyone thought. At a long press conference held after IPCC released its report, Climate Change 2013: The Physical Science [...]

Spot the Differences in the New IPCC Report

Changes have been made. No, I’m not talking about the difference between the 2007 climate change report from the Intergovernmental on Climate Change versus this latest iteration. I’m talking about the summary for policymakers released today versus the leaked drafts. Climate scientist Thomas Stocker of the Universty of Bern, co-chair of the working group responsible [...]

Talk about management by committee: one group of more than 800 scientist authors to cope with more than 9,000 scientific publications on climate change and more than 20,000 comments from “expert reviewers” (plus another 30,000 or so from various other interested parties.) Now the Intergovernmental Panel on Climate Change is into four days of wrangling [...]

The Climate May Be Changing, but the IPCC Remains the Same

ipcc-first-session-in-1988

By 2021, climate scientists should be 99 percent certain that climate change is our fault—up from 95 percent certain presently and a mere 90 percent certain all the way back in 2007. This conclusion of the leaked draft of the forthcoming assessment of the Intergovernmental Panel on Climate Change (IPCC) begs the question: Is any of [...]

Are There “Serious Flaws” in the EPA’s Bid to Regulate Greenhouse Gases?

epa-headquarters

Did the U.S. Environmental Protection Agency err when it found in 2009 that greenhouse gases, like carbon dioxide, endanger public health? Based on a new report from the agency’s Inspector General, climate change denier and U.S. Sen. James Inhofe, R-Okla., would like you to think so, trumpeting in a press release headline that the “EPA [...]

U.K. Government: “Climategate” No Reason to Doubt Climate Change

Smokestacks at a power plant

Yet another scientific body has jumped in to the so-called climategate fray to dispute that the leaked documents offer any reason to doubt that human activity is warming the planet. Back in 2009, as you may recall, a number of e-mails and documents related to climate research were leaked following a server breach at the [...]

The Importance of Debating Energy Policies—Not Technologies

The U.S. Energy Information Administration (EIA) documents the source of all U.S. primary energy use, and then approximates to which sector energy from each source flows. (Source: EIA)

As a researcher working in the area of energy technology and policy, I often find myself drawn into debates surrounding certain energy technologies, and what role they should play in the future energy system. People are quick to list the specific benefits or drawbacks of one technology over another: “Wind energy is fine at the [...]
