Global Warming Imperils U.S. Future If We Don't Stop 'Risky Business'

Published: June 24, 2014

If you don't like hot and humid weather, you're not going to like what the future feels like in much of the United States.

That's because in many parts of the country, the number of days that reach 95 degrees or higher each year will double or even triple as in Georgia, where the number of days over 95°F will jump from a few weeks today to as much as a third of the year by the end of the century.

What will that mean? Besides being unbearably hot for some people, it will change what crops can grow there as well as what people can and can't do outside (and when they can do it), which will have potentially massive impacts on industries like farming, transportation and construction.

But that possible future isn't inevitable. Americans can take action now to prevent it from coming to pass, a bipartisan group of the nation's top business and political leaders said in a new report on the economic risks of climate change that lays out those risks in unsparing detail, region by region and state by state.

Called "Risky Business," the report is the work of some of the biggest names in American politics and business, including former New York City Mayor Michael Bloomberg, former Treasury Secretaries Henry Paulson and Robert E. Rubin, former U.S. Senator Olympia Snowe and Tom Steyer, a former hedge fund manager turned philanthropist and environmentalist.

“With the oceans rising and the climate changing, the Risky Business report details the costs of inaction in ways that are easy-to-understand in dollars and cents -- and impossible to ignore," said Bloomberg in a press release announcing the report.

“Climate change is the existential issue of our age -- it is cumulative and irreversible, and its impacts are potentially catastrophic and pose enormous threats to our country’s economic and fiscal health,” added Rubin, who served as Treasury Secretary under President Bill Clinton.

The Risky Business co-chairs and contributors based their report on both the U.S. National Climate Assessment, released in May, and their own analysis of climate change in America by the Rhodium Group, an economic research firm that specializes in global trends for investors and companies, largely in the energy industry.

What they found is that the American economy is already starting to feel the first effects from human-caused global warming, due to the buildup of greenhouse gases in the atmosphere since the dawn of the Industrial Revolution.

How? The most obvious example is sea level rise, which already today swallows up roughly a football-field-sized patch of the Louisiana delta every hour. And by mid-century, sea level rise -- along with heightened storm surges -- could put tens of billions of dollars' worth of coastal property underwater.

That's not just beach houses on stilts, the report authors add. Also lost will be critically important infrastructure now located on or near the coasts, like airports, oil and gas refineries, shipping ports, and the drinking water and sewer systems for entire cities (most notably Miami).

Because so much of the nation lives along the highly vulnerable coast -- in the Northeast, the report points out, 88 percent of the population lives in coastal counties and 68 percent of the region's economic output is generated there -- taking action on climate change today isn't a cause; it's an emergency.

Donna Shalala, the president of the University of Miami and former U.S. Secretary of Health and Human Services under President Clinton, said in a press release that the time for that action is now:

“Will we sit by and watch as many of our coastal cities face an ever-rising sea, and as severe heat strains our electric grids and hobbles our workers? Or will we act now to help reduce the risk that these impacts will spiral out of control in the future? It’s time for us all to step up.”

March 2015: Another Warmest Month on Record for the Planet

By Dr. Jeff Masters
April 17, 2015

March 2015 was the warmest March since global record keeping began in 1880, said NOAA. March 2015's warmth makes the year to date period (January - March) the warmest such period on record, and the past twelve months the warmest twelve-month period in recorded history. Seven of the past eleven months (May, June, August, September, October, and December 2014, along with March 2015) have tied or set new record high monthly temperatures.

The Great California Storm of April 19-23, 1880

By Christopher C. Burt
April 11, 2015

Could a single big late–season storm have a significant impact on the California drought? A 'Hail Mary' storm event? Normally by this time of the year (April 10th) California would have already received at least 90% of its rainy-season precipitation total and any additional rain or snowfall would have little impact so far as the current drought is concerned. However, back in late April 1880, one of the most intense storms ever to pound the state occurred. Here are the details.

What the 5th IPCC Assessment Doesn't Include

By Angela Fritz
September 27, 2013

Melting permafrost has the potential to release an additional 1.5 trillion tons of carbon into the atmosphere, and could increase our global average temperature by 1.5°F in addition to our day-to-day human emissions. However, this effect is not included in the IPCC report issued Friday morning, which means the estimates of how Earth's climate will change are likely on the conservative side.
