July 27, 2016--The Colorado River’s unexpected carbon footprint (High Country News)

When water rushed over the dry riverbed of the Colorado River Delta for the first time in two decades, thousands of bubbles popped up in the sand. Alongside the bank, a group of scientists stood in awe, theorizing that oxygen and nitrogentrapped in the sediment were the cause.


February 16, 2015--Scientists look at role of wetlands in battle against climate change (Phys.org)

The role rainforests play through storing carbon in the battle against climate change is well understood, but Deakin University scientists now believe the humble swamp, or freshwater wetland, could be up to 50 times more effective.


February 16, 2015--NASA climate study warns of unprecedented North American drought (Guardian)

California is in the midst of its worst drought in over 1,200 years, exacerbated by record hot temperatures. A new study led by Benjamin Cook at NASA GISS examines how drought intensity in North America will change in a hotter world, and finds that things will only get worse. Global warming intensifies drought in several ways. In increases evaporation from soil and reservoirs.


January 14, 2015--The tides are changing: Sea levels rising at faster rate than predicted, study finds (Independent)

Global sea levels have risen faster than previously thought over the past century, suggesting that climate change is having a greater-than-expected impact on the rising oceans, a study has found. A new way of estimating global sea levels since the start of the 20th Century found that the period 1900-1990 experienced a 30 per cent smaller rise than researchers had previously calculated.


December 5, 2014--Adapting to a warmer climate could cost almost three times as much as thought, says UN report (Guardian)

Adapting to a warmer world will cost hundreds of billions of dollars and up to three times as much as previous estimates, even if global climate talks manage to keep temperature rises below dangerous levels, warns a report by the UN.


December 5, 2014--The critical role crops play in the Earth's CO2 cycle (Environmental News Network)

Each year, the planet balances its budget. The carbon dioxide absorbed by plants in the spring and summer as they convert solar energy into food is released back to the atmosphere in autumn and winter. Levels of the greenhouse gas fall, only to rise again. But the budget has gotten bigger.


September 10, 2014--Carbon dioxide concentration surges: Record greenhouse gas levels impact atmosphere and oceans, WMO report finds (Science Daily)

The amount of greenhouse gases in the atmosphere reached a new record high in 2013, propelled by a surge in levels of carbon dioxide. This is according to the World Meteorological Organization's annual Greenhouse Gas Bulletin, which injected even greater urgency into the need for concerted international action against accelerating and potentially devastating climate change.


July 15, 2014--Drought conditions linked to human activity (Environmental News Network)

US Government scientists have developed a new high-resolution climate model that shows southwestern Australia's long-term decline in fall and winter rainfall is caused by increases in manmade greenhouse gas emissions and ozone depletion.


June 17, 2014--Climate change threatens tourism as ski slopes thaw, seas rise (NPS Colorado)

Climate change is a growing threat to tourism, from thawing ski resorts to coral reefs hit by warmer seas, and the industry itself should do more to curb its soaring greenhouse gas emissions, a study showed on Tuesday.


May 23, 2014--Dust bowl days: Will we cut carbon pollution fast enough to prevent permanent droughts? (Climate Progress)

Large parts of the Southwest are drier than they were during the 1930s Dust Bowl. And the latest science says unrestricted carbon pollution will make this a near-permanent situation post-2050 in a growing portion of this country and around the world — for a thousand years or more! Earlier this month, the U.S.
