Climate Change Already Hammering the US

No matter what George Will says—extreme weather, drought, heavy rainfall, and increasing temperatures are already fact of life in many parts of the US thanks to human-induced global warming. Changes like these will increase in intensity from here on.

That’s according to Global Climate Change Impacts in the United States, a 190-page report two years in the making, issued today, product of the US Global Change Research Program, including NOAA and 12 other US government science agencies, major universities, and research institutes. Some of the findings from the Midwest alone:

  • Average temperatures have risen in the Midwest in recent decades, especially in winter
  • The growing season is one week longer
  • Heavy downpours are twice as frequent as they were a century ago
  •  The Midwest has experienced two record-breaking floods in the past 15 years
  • Average annual temperatures are expected to increase two degrees Fahrenheit over the next few decades—and as much as 7 to 10 degrees by the end of the century, with more warming projected for summer than winter
  • Precipitation is expected to increase in the winter and spring
  • Summer precipitation will likely decline
  • More of the precipitation is likely to occur during heavier events
  • As temperatures and humidity increases, heat waves, reduced air quality, insect-borne diseases, pollen production, and growth of fungi are more likely to occur
  • Heavy downpours will overload drainage systems and water treatment facilities, increasing the risk of waterborne diseases
  • Average water levels in the Great Lakes—reservoirs for 20 percent of the planet’s fresh surface water—could drop as much as two feet this century, affecting beaches, coastal ecosystems, fish populations, dredging, and shipping

Some of the effects of the changing climate are already inevitable and will require human and animal populations to adapt. Other effects can be mitigated by limiting future emissions of C02 and other greenhouse gases… George Will won’t but we have to.
 

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
