Carbon dioxide levels hit 395 parts per million in 2012, the highest in four or five million years when sea levels were around 80 feet higher and temperatures up to 10° Fahrenheit hotter. If we sustain those CO₂ levels, or go higher as we are doing, a completely different world will emerge. 

Wyoming's only new coal mine, Kiewit's Haystack Mine in SW Wyoming, halted construction yesterday before shipping any coal. Why should we care about coal mining in Wyoming? Short answer: it is at the heart of the biggest coal mining region in the United States, and by some calculations the world. 

Urban green infrastructure is increasingly seen as an effective way to meet regulatory obligations for control of polluted runoff or high stormwater flows, while also generating an array of ecosystem service co-benefits.

Tidal wetlands provide great potential to sequester and store greenhouse gases. Restore Americas Estuaries and EarthCorps are investigating the carbon sequestration value of tidal wetlands.

Australia is launching one of the most ambitious ‘blue carbon’ mapping projects ever.  ‘Blue carbon’ is the capture and storage of carbon pollution from the atmosphere in ocean plants and sediments on the seabed.

How much carbon is stored in natural systems of the continental western US?  How much will be stored in future decades? A new US Geological Service survey provides some sobering answers.

Imagine a world where we invest billions of dollars in improving ecosystem resilience to help combat climate change, all because doing so sucks up vast amounts of carbon dioxide (CO2) and provides pure oxygen in return.
