At the poles, more heat radiates out into space than is absorbed from the sun.
Rocket Lab launches NASA cubesat to study heat lost from Earth's poles
"The PREFIRE duo "will criss-cross over the #Arctic and #Antarctica measuring thermal infrared radiation — the same type of energy emitted from a heat lamp — that will make #climate models more accurate and help predict changes caused by #GlobalWarming," Rocket Lab wrote in a mission description."
The warmest 12-months in millennia for the Earth as a whole is right now. For the Arctic though, the warmest 12-months was in 2016, with the post-2019 years notably less hot.
I explore the "where" and "why" in the latest Alaska and Arctic Climate newsletter. #akwx#Arctic#Climate#Alaska
Huge jellyfish invasion could disrupt Arctic ecosystems as waters warm.
New Scientist reports: "The Arctic could see a surge of jellyfish as climate change leads to warmer waters and less ice – a process known as 'jellification.'"
Given that the serious impacts of climate change are rapidly escalating, some scientists, backed up increasingly by governments, are looking into extreme measures such as geoengineering to slow the rate of change.
A new report examines 61 climate mitigation ideas for the Arctic, including geoengineering.
What's Normal in a Changing Arctic Climate?
Depends on your interest
"Is Updating Once a Decade Enough?
Part of the impetus for updated baseline every ten years is to keep up with the changing climate. The Arctic though is warming so fast that this once-a-decade update is not sufficient to keep up the pace of change." https://alaskaclimate.substack.com/p/whats-normal-in-a-changing-arctic From Rick Thoman @AlaskaWx
