- Summary:
- A novel approach to geochemical measurements helps scientists reconstruct the past intensity of the methane seeps in the Arctic Ocean. Recent studies show that methane emissions fluctuated, strongly, in response to known periods of abrupt climate change at the end of the last glacial cycle.

FULL STORY
Past records of methane release are crucial for understanding future climate changes. Methane is a potent greenhouse gas, that has had significant impact on climate changes in the geological past.
“Previously, when dating the natural release of methane, we used to measure mostly carbon isotopes. But now we know that carbon isotopes alone can’t tell us the full story of past emissions of this greenhouse gas.” says professor Giuliana Panieri, from CAGE Centre for Arctic Gas Hydrate, Environment and Climate at UiT The Arctic University of…
