Climate 411

This post is by Sheryl Canter, an Online Writer and Editorial Manager at Environmental Defense.

Americans have a love affair with coastal living. Waterfront property is highly coveted and highly priced. And now may be nearly impossible to insure due to skyrocketing damage costs from hurricanes.

These are some of the findings in a new report from Environmental Defense titled Blown Away: How Global Warming is Eroding the Availability of Insurance Coverage in America’s Coastal States [PDF]. "Across the board, the nation’s largest carriers have declared their intentions to reduce exposure in high-risk areas by raising rates, hiking deductibles, limiting coverage and in many cases, pulling out of risky markets altogether."

Here are some more highlights from the report.

Climate Vote 2007

Part of a series on the work of the Environmental Defense Action Fund to enact an effective climate law. You can help by writing to Congress.

November 1, 2007, may go down as America’s D-Day in the fight to avert the global warming crisis. A key Senate subcommittee just passed the Lieberman-Warner America’s Climate Security Act (S.2191) – a bipartisan bill to cap and reduce America’s global warming pollution.

The full Environment & Public Works Committee is expected to take up the legislation the week of November 12, so it could come to a vote by the end of the month. With this bill we have a real chance of passing a mandatory cap on emissions in this Congress!

The award of the 2007 Nobel Peace Prize to Al Gore and the Intergovernmental Panel on Climate Change (IPCC) is an important milestone in the journey toward a global warming solution, and it got me thinking about how the IPCC came to be. To some extent, it was thanks to a miscalculation by the Reagan Administration!

A study by Weaver et al., published this month in the journal Geophysical Research Letters, reports that "All emission targets considered with less than 60% global reduction by 2050 break the 2.0°C threshold warming this century…." (They mean 2.0°C above the pre-industrial temperature, equivalent to 2.3°F above today’s temperature. For more on threshold temperatures, see “How Warm is Too Warm?“) Even more disturbing, they say, "Even when emissions are stabilized at 90% below present levels at 2050, this threshold is eventually broken."

That makes all our efforts seem hopeless. But are they right? In a word, no. Here’s why.

Yesterday’s New York Times Magazine had an article aptly titled "The Future is Drying Up", about the threats that climate change and booming populations pose to precious water resources in western states. Usually when we think of water and climate change we think of rising sea levels, but climate change is also causing drops in drinking water supplies.

We’re already seeing environmental changes from global warming, and some key ones are occurring more quickly than scientists expected. Consequently, many experts from diverse disciplines are uncomfortable with the slow pace of governments in addressing this issue. The growing sense of urgency arises from two concerns:

• Earth’s climate system may be rapidly approaching a point of no return where large, irreversible and destructive changes, like the gradual disintegration of an ice sheet, become inevitable.
• To achieve any given temperature goal, the longer we delay action, the steeper emissions reductions will need to be. It’s easier to cut emissions gradually than it is to slash them drastically.
