Pre-industrial anthropogenic CO2 emissions: How large?

Guest article by William Ruddiman Fifteen years after publication of Ruddiman (2003), the early anthropogenic hypothesis is still debated, with relevant evidence from many disciplines continuing to emerge. Recent findings summarized here lend support to the claim that greenhouse-gas emissions from early agriculture (before 1850) were large enough to alter atmospheric composition and global climate substantially. Marine isotopic stage (MIS) 19 is the closest orbital analog to the current MIS 1 interglaciation (Tzedakis et al., 2012), with similarly small changes in precession (εsinω) and nearly

Dear God, is Oil a Blessing or a Curse?

David Suzuki: Climate Deniers Are Wrong … CO2 Emissions Are Wreaking Havoc on the Planet

Life evolved to live within limits. It’s a delicate balance. Humans need oxygen, but too much can kill us. Plants need nitrogen, but excess nitrogen harms them and pollutes rivers, lakes and oceans. Ecosystems are complex. Our health and survival depend on intricate interactions that ensure we get the right amounts of clean air, water, food from productive soils and energy from the sun. Water flowing to the ocean from the Greenland ice sheet. macaroni2552 / Imgur Climate change deniers either willfully ignore or fail to understand this complexity—as shown in their simplistic argument that carbon

A recent House Energy and Commerce Committee meeting was the latest venue for Republican ranting that climaxed in a condemnation of the Clean Power Plan as “un-American.” Janet McCabe, the EPA’s acting assistant administrator, was called as a witness to Is the Clean Power Plan Un-American?
