What can Hurricane Isaac teach us about climate vulnerability?


As with any single event, Hurricane Isaac doesn’t tell us anything about whether hurricanes are getting worse due to climate change. But Isaac’s impacts should be examined to teach us about our vulnerabilities to the types of extreme events scientists tell us climate change will make more common.

Two More Lows for Arctic Sea Ice

The loss of Arctic sea ice is progressing more rapidly and clearly than just about any other indicator of global climate change. As I’ve discussed previously, the minimum summer sea ice extent (i.e. the two-dimensional area of the floating ice cap) set new record lows in 2002, 2005 and 2007. Similarly, the total volume of sea ice set record lows in 2007, 2010 and 2011. For the first time since 2007, both the sea ice extent and volume have set new record lows in the same year (see figures). And what’s more, they did it with weeks remaining in the melt season, which usually ends in mid-September. So the records have been broken this year, but we don’t know yet just how low the extent and volume will go.

C2ES Releases New Extreme Weather Map on Eve of Senate Climate Hearing

C2ES Releases New Extreme Weather Map on Eve of Senate Climate Hearing

The Center for Climate and Energy Solutions (C2ES) has created a new online map providing an overview of extreme U.S. weather events since 1990. The map highlights examples of extreme heat, heavy precipitation, drought, and wildfire -- four types of events with clear trends connected to climate change.

In a blog post announcing the new map, C2ES science and policy fellow Dan Huber summarizes the recent run of extreme weather:

“Climate change is elevating the risk of extreme weather,” writes Huber. “It’s crucial that we take stock of what each disaster teaches us so that we understand the rising risks and are better prepared for what’s to come.”

The science behind climate change will be the focus of a hearing tomorrow (Wednesday, Aug. 1) before the Senate Environment and Public Works Committee titled “Update on the Latest Climate Change Science and Local Adaptation Measures.” The hearing, set for 10 a.m. in 406 Dirksen, is the Senate’s first in this Congress focusing directly on climate change science.

About C2ES: The Center for Climate and Energy Solutions (C2ES) is an independent non-profit, non-partisan organization promoting strong policy and action to address the twin challenges of energy and climate change. Launched in November 2011, C2ES is the successor to the Pew Center on Global Climate Change.

Agreeing on the problem, if not the solution

Despite the very different views of the majority and minority parties in the Senate, there was in fact a fair degree of agreement among the witnesses at today’s hearing on climate science and local adaptation.

During the climate science portion of the Senate Environment and Public Works Committee hearing, both the majority and minority witnesses agreed that the Earth has warmed over the past 120 years. With the recent publication of the Berkeley Earth Surface Temperature project by former skeptic Richard Muller, there are now four (NOAA, NASA and Hadley are the others) major global temperature records that are in agreement that the Earth has warmed 1.5 degrees Fahrenheit over the past 50 years.

Business and government start preparing for climate impacts

Today’s Senate hearing isn’t just about the science of climate change. It’s also about the actions that need to be taken now to adapt to the reality of a changing climate. Businesses and governments each have a critical role to play in building resilient communities and economies.

Business-as-usual is already being interrupted by extreme heat, historic drought, record-setting wildfires, and flooding. Events from water shortages to floods are disrupting the supply chains for such companies as Honda, Toyota, Kraft, Nestle and MillerCoors. By the end of 2011, the United States had recorded more billion-dollar disasters than it did during all of the 1980s, totaling about $55 billion in losses.

Senate gets back to climate science

The Senate Environment and Public Works Committee holds a hearing tomorrow called “Update on the Latest Climate Change Science and Local Adaptation Measures.” This is the first Senate hearing focused directly on climate science in the 112th Congress, and we hope it won’t be the last. Climate change is happening, the news from peer-reviewed science is increasingly daunting, and the public needs to hear what credible scientists are learning about the risks and potential solutions.

Mapping extreme weather across the U.S.

Today we’re updating our online map providing an overview of extreme weather events in the United States since 1990.  The map highlights memorable examples of extreme heat, heavy precipitation, drought, and wildfire, four types of events with clear trends connected to climate change.

Is Global Warming Causing Wild Weather?

I recently responded to a question on the National Journal blog, "Does climate change cause extreme weather like the heat waves much of the country has been enduring for the past few weeks?"

Congress Finally Reforms Flood Insurance

Late last week, in a heartening display of bicameral and bipartisan harmony, Congress passed a bill reauthorizing the National Flood Insurance Program (NFIP) and taking steps to steer it toward solvency. Among those steps is ensuring that climate impact projections are factored into future calculations of flood risk.
