 Ancient Methane Seeps Tell Tale of Sudden Warming

Researchers gather around and study an ancient Arctic methane seep mound discovered in the 1970s. In the summers of 2010 and 2011, the researchers discovered more than 100 defunct seeps on Ellef Ringnes Island in Canada’s High Arctic. Credit: Derrick Midwinter

Krista Williscroft and her colleagues trudged for days through mud, often up to their knees, cataloging large mounds of rock across a desolate landscape. Constant sunlight, a light breeze, and temperatures hovering around freezing on Ellef Ringnes Island made for a pleasant field campaign—at least, as pleasant as it could get for the Canadian High Arctic.

Interesting, but still infected with the global warming cult disease.

Although the researchers can’t say for certain how the seeps affected their ocean environment—much less Earth’s climate at the time—it’s clear they represent “sudden releases of methane related to warming,” Grasby said.

Clearly the fault of dinosaurs and their SUVs.
