4 Dire Warnings From Bipartisan Report 

on Climate Change's Economic Impact

Risks include flooding, disruption to farming, and dangerous heat.

A Tuesday report warning of dire economic consequences from climate change, from lost property to ruined crops, is the latest in a string of bipartisan efforts aimed at garnering public support to tackle the problem.
Tuesday's report is from a coalition of top U.S. political and economic leaders from the left, right, and center—including three former Treasury Department secretaries going back to the Nixon White House—and was reviewed by leading climate scientists.
"What we ultimately need is not just investment in resiliency to adapt to the outcomes we know are coming ... We need strong policy action to prevent the very worst outcomes, and I think that takes action by national government," said report co-chair Henry Paulson, who was Treasury secretary under George W. Bush.
Called "Risky Business," the 56-page report says risks posed by climate change over the next century include extensive property damage from catastrophic flooding and sea-level rise and severe disruption of agriculture in the American corn belt and Southeast. But it also said there is still time to act.
"If we continue on our current path, many regions of the U.S. face the prospect of serious economic effects from climate change," the report says. "However, if we choose a different path—if we act aggressively to both adapt to the changing climate and to mitigate future impacts by reducing carbon emissions—we can significantly reduce our exposure to the worst economic risks from climate change, and also demonstrate global leadership on climate."
As an example of how businesses might address climate-related risks, report co-chair and former New York Mayor Michael Bloomberg says he's moving one of his media company's key computer centers from lower Manhattan, which is at increased flooding risk, to upstate New York.
"I want to sleep at night," he said at a Tuesday press conference.
Report co-chair Tom Steyer, the retired founder of Farallon Capital Management, said that investors need to "get to a place where the calculation of a value of a company includes how they are handling this problem."
The report's GOP contributors were moderates, including Bloomberg and former Reagan Secretary of State George Shultz, and follows a series of recent warnings from groups that included middle-of-the-road Republicans.
Last month, 16 retired three- and four-star generals and admiralsreleased a report calling climate change "a catalyst for conflict" that may lead to instability and disrupt global networks of trade and resources.
But global warming remains a politically polarized issue. Gallup's March 2014 poll found that just 42 percent of Republicans think most scientists believe global warming is occurring, compared with 82 percent of Democrats.
report released in late May by the conservative-leaning U.S. Chamber of Commerce argued that the administration's new rule would cost $51 billion annually by 2030 and lead to a loss of 224,000 jobs.
Here are four of the report's most dire warnings:
1. A lot of coastal property and infrastructure is at risk.
The report warns that within the next 15 years, higher sea levels and storm surges will likely increase the average annual cost of coastal storms along the eastern seaboard and the Gulf of Mexico by somewhere between $2 billion to $3.5 billion. Adding in potential changes in hurricane rates and severity, the likely increase in average annual losses grows to up to $7.3 billion, bringing the total annual price tag for all coastal storms to $35 billion.
2. Farms face a significant decrease in crop yields.
Because of climate change, some midwestern and southern counties could see a decline in agricultural yields of more than 10 percent over the next 5 to 25 years, with a 1-in-20 chance of yield losses of more than 20 percent.
3. Energy costs are set to rise.
Rising temperatures will likely require construction of up to 95 gigawatts of new power generation capacity over the next 5 to 25 years—roughly 200 coal or natural gas-fired power plants—thanks to increased cooling loads. That expansion will cost ratepayers up to $12 billion per year.
4. Expect more extreme heat.
Heat waves will become more likely in the next decades, especially in the Southwest, Southeast, and upper Midwest. This will threaten human health, labor productivity, and energy systems.
"By the middle of this century, the average American will likely see 27 to 50 days over 95°F each year—two to more than three times the average annual number of 95°F days we've seen over the past 30 years," the report warns. "By the end of this century, this number will likely reach 45 to 96 days over 95°F each year on average."
