“Scientists in Germany are studying a 1.2-million-year-old ice core retrieved from Antarctica after years of planning and months of drilling in temperatures of -35 degrees Celsius (-31 Fahrenheit).

[It’s] the oldest continuous ice core to have ever been drilled. The scientists are now hoping it will unlock vital information about the Earth's climate.”

Wherever you go, show me a political leader calling themselves a "conservative" & I'll show you a denier of #ClimateScience who now has to resort to increasingly sillier reasons for the world we all see burning around us.

And political stunts like letters to Canada

NBC News · Republicans across the country are pushing bills to stop government 'weather modification'By Allan Smith

Next week our ECR group are starting a #MachineLearning sprint to speed up the development of our new #IceSheet surface mass budget emulation models.

I'm looking for hints, ideas tips and inspiration to help smooth and accelerate the process.

If you're used to working in #Sprint mode, what in your opinion makes it work or otherwise hinders it?

What can I as supervisor do to make it run better?
And how should we celebrate it's conclusion?

Also, should me do an #AMA on the process?

Warming Arctic lakes may release more methane than expected

The findings are important because #methane is over 25 times more powerful than #CarbonDioxide as a #GreenhouseGas. #Arctic lakes are already major natural methane sources globally, but the processes that control how methane is produced and released from lake sediments have remained poorly understood—until now.

"We were surprised by how clearly the productivity of the ecosystem was linked to methane production," said Marie. "Our results show that warmer and wetter conditions increase biological productivity in Arctic lakes, which in turn drives methane #emissions from their sediments."

Most methane was produced within the top 10 cm of lake #sediment. In these shallow layers, the combination of fresh, organic-rich material and enhanced microbial activity creates ideal conditions for methane generation. The researchers calculated how much methane is likely to diffuse from the sediment into the overlying water and eventually into the atmosphere.

"The Arctic is changing rapidly, and we need to understand all the feedback involved," said Marie. "Our work suggests that increases in ecosystem productivity—something we could think of being positive—can also increase methane release and further accelerate warming."
