Hurricane Harvey is Already the Worst Rainstorm in U.S. History, and it’s Still Raining

by

Since Hurricane Harvey made landfall in Texas late Friday night, more than 40 inches of rain have fallen in parts of the Houston metro area, producing the worst flood in the city’s modern history. The latest forecasts show another 15-25 inches on the way before Harvey clears out of the area on Wednesday. Harvey is sure to rank as the worst rainstorm in U.S. history, according to an initial analysis from the Texas state climatologist.

Climate Science: Business As Usual

by

When we hear about the emissions scenarios used in the Intergovernmental Panel on Climate Change (IPCC) reports, do we really understand what they’re assuming about future fossil fuel combustion? And what do these emissions scenarios imply about the steps needed to achieve climate policy goals and decarbonize our energy system?

Record Heat in 2016 Broke Lake Temperature Records Too

by

An annual analysis of the planet’s climate reaffirms what researchers knew was the case: that 2016 was the hottest year since at least 1880, when reliable global measurements were first kept. Record concentrations of heat-trapping gases and a strong El Nino raised the global average temperature to a new high, breaking a mark set just a year earlier.

July 2017 Stormwatch: Climate Change

by

This month we’re going to talk about the current pace of anthropogenic climate change. That’s perhaps the most massive story of our time; it’s happening a good deal faster than I expected — though in all fairness, a great many climate scientists have been caught flatfooted by the pace of change as well.

Why Climate Change Belongs in the Health Care Debate

by

I’m digging through reports and punditry to make sense of health care reform when I realize that while we’ve been debating single-payer systems and high-risk pools, no one’s talking about the most serious health threat: climate change. I know what global warming is doing to our ecosystems. My Twitter feed is a stream of climate disaster revelations. Given the serious implications droughts, floods, and fires pose to our health, shouldn’t climate change be part of the health care discussions?

The Impacts Of An Ice Free Arctic: A Climate Paradigm Shift?

by

The paper “Mitigation implications of an ice-free summer in the Arctic Ocean”[4] provides estimates for the effect of an ice-free Arctic in the month of September in 2050 and 2040. As the paper comments, the possibility of an early loss in arctic sea ice has not been included in any of the Integrated Assessment Models used to assess the societal impacts of climate change.

Oroville Emergency a Warning for U.S. Dam Safety

by

The near-failure on Sunday evening of the auxiliary spillway at Oroville Dam and the ongoing emergency operations to contain flood waters in California’s second-largest reservoir and shore up its eroding outlet are a tale of caution for the nation’s aging dam fleet.
