2016 Was Second Hottest Year For US In More Than 120 Years of Record Keeping (climatecentral.org)
Last year was the second hottest year for the United States in more than 120 years of record keeping, according to the National Climatic Data Center, marking 20 above-average years in a row. While Georgia and Alaska recorded their hottest year, every state had a temperature ranking at least in the top seven. Climate Central reports: The announcement comes a week before the National Oceanic and Atmospheric Administration, which released the U.S. data, and NASA are expected to announce that 2016 set the record for the hottest year globally. Both the global record and the U.S. near-record are largely attributable to greenhouse gas-driven warming of the planet. In addition to the pervasive warmth over the last year, the U.S. also had to deal with 15 weather and climate disasters that each caused more than $1 billion in damage. Together, they totaled more than $46 billion in losses and included several disastrous rain-driven flooding events. These events, along with continued drought, lay bare the challenge for the country to learn how to cope with and prepare for a changing climate, said Deke Arndt, the climate monitoring chief of NOAA's National Centers for Environmental Information. The temperature for the contiguous U.S. was 2.9 degrees Fahrenheit above the 20th century average for 2016, displacing 2015 and ranking only behind 2012, when searing heat waves hit the middle of the country. More notable than the back-to-back second place years, Arndt said, was that 2016 was the 20th consecutive warmer-than-normal year for the U.S. and that the five hottest years for the country have all happened since 1998. Those streaks mirror global trends, with 15 of the 16 hottest years on record occurring in the 21st century and no record cold year globally since 1911. -
Analyzing Climate Change On Carbon Rich Peat Bogs
eldavojohn writes "A new report (PDF) from Climate Central shows that climate change has been affecting some states more than others for the past 100 years. As you can see from a video released by NASA, things have become most problematic since the 70s. Among the states most affected is Minnesota, where moose populations are estimated to have dropped 50% in the past six years. Now the U.S. Department of Energy is spending $50 million on a massive project at the Marcell Experimental Forest to build controlled sections of 36 feet wide and 32 feet tall transparent chambers over peatland ecosystems. Although peat bogs only account for 3% of Earth's surface, they contain over 30% of carbon stored in soil. They aim to manipulate these enclosures to see the effects of warming up to 15 degrees, searching for a tipping point and also observing what new ecosystems might arise. The project hopes to draw attention and analysis from hundreds of scientists and researchers around the globe." -

Carbon Dioxide Emissions Fall Worldwide In 2009
Hugh Pickens writes "The Christian Science Monitor reports that the good news is that emissions from burning coal, oil, and natural gas fell 1.3 percent compared with emissions in 2008 primarily because of the global economic downturn and an increase in carbon-dioxide uptake by the oceans and by plants on land. One big factor was La Niña, a natural seesaw shift in climate that takes place across the tropical Pacific every three to seven years, where the climate is cooler and wetter over large regions of land in the tropics, encouraging plant growth in tropical forests. However the bad news is that even with the decrease in emissions the overall concentration of CO2 rose from 385 ppm in 2008 to 387 ppm in 2009, as concentrations continue to rise even as emissions slip because even at the reduced pace, humans are pumping CO2 into the atmosphere faster than natural processes can scrub the gas. Many countries have agreed in principle to try to stabilize emissions at 350 ppm by century's end, which would result in a 50 percent chance of holding the increase in global average temperatures to about 2 degrees C over pre-industrial levels."
