The vast stands of thick rain forecast suck up carbon dioxide and store some of the extra carbon we humans have been belching into the atmosphere for a century. This uptake of atmospheric CO2 is an offset more rapid climate change. But massive deforestation and changes in regional climate are making the Amazon a less effective carbon sink. Read more →
Just two months after data confirmed 2014 was the warmest year on record globally we know that 2015 is off to an even warmer start than 2014 was one year ago. In fact, the first two months of 2015 are significantly warmer than January and February 2014 globally. Read more →
To some climate change seems a far off distant future concept. Not to US military and intelligence agencies.
A growing body of evidence suggests climate change and prolonged drought helped sew the seeds of conflict in Syria and western Iraq. Even small shifts in climate in marginal climate zones can have disproportionate impacts. Read more →
Minnesota rides the edge of winter this year. Occasional brief stabs of arctic air fight to hang on. Pacific winds lie in wait, ready to deliver the next thaw as temperatures run toward the 30s. Above zero.
The first two thirds of meteorological winter ran about 4 degrees warmer than average. February’s attempted winter is off to a brisk start with temps running a good -7 degrees vs. average so far. Read more →
We know the longer term trends show Minnesota is warming fastest in winter. But what you may not realize is much smaller shifts in winter climate have a huge impact in ice coverage on lake like Superior. Read more →
As I wrote last week, NOAA and NASA officially announced Friday that 2014 was the warmest year on record globally since modern temperature records began in 1880. Read more →
The case that 2014 was the warmest year on record globally may be about to get confirmation from two separate major US science groups.
An inside source tells me NOAA and NASA will likely schedule a joint news conference late next week to confirm 2014 as the warmest year on record globally.
Both NOAA and NASA keep separate data sets on global surface temperatures, and are expected to declare the final December data puts 2014 in the top spot as the warmest year on record since 1880. The two organizations usually announce global temperature results separately online, so a joint news conference would be unusu Read more →
Deliberation and debate resound in the halls of Washington, D.C. these days. Among the hot topics? The proposed Keystone XL pipeline. Keystone would move massive amounts of Canadian “tar sands” oil south to facilities in the southern US. There’s a lot of debate about the politics of Keystone. But what about the science of pumping the Read more →
I’ve been talking with MPR Climate Cast contributor University of St. Thomas Professor John Abraham this week about what it will take for 2014 to “officially” be declared the warmest year on record globally. John is at the American Geophysical Union conference in San Francisco this week. John and I traded data including the National Oceanic and Read more →
Winters are warming faster in Minnesota than any other region of the country, according to a recent study. Read more →
