Methane from plants increased by climate change

The debate about climate change has focused on one polarizing gas: carbon dioxide. CO2 and its portrayal to the general public is controversial because on one hand, it’s essential for all life, since plants need to breathe too.  But on the other hand it’s a greenhouse gas that traps heat in our atmosphere, and in some instances –such as new interpretations of the Clean Air Act–is regulated as a pollutant. But...

EPA biofuels rule: calculating the payback

The EPA released a report yesterday that proposes to change the rules of the biofuels game.  The report, titled “Regulation of Fuels and Fuel Additives: Changes to Renewable Fuel Standard Program,” examines the lifecycle of corn-for-ethanol practices and sets the “payback” period of carbon emissions for corn-for-ethanol fuel as 33 years. The payback period means that at first, corn-for-ethanol practices will be...

Forests might flip from carbon sink to source

Ecologists point to forests as important sinks for atmospheric carbon. But a new report suggests that climate change could induce environmental stresses that would chnge the role of forests into a net carbon source. The report, titled “Adaptation of Forests and People to Climate Change – A Global Assessment,” was coordinated by the International Union of Forest Research Organizations (IUFRO) and the Collaborative...

While the Obama administration is weighing whether to use the Clean Air Act to regulate emissions, House...
