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.
@nguarracino My family was in the post office for 101 years. My grandfather, father, and brother were all postmasters back home in Roblin. This stamp was issued in 1929, the year my dad was born and the tattoo is meant to honour him.
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
Climate normals and the Arctic is this week's topic for the Alaska and Arctic Climate Newsletter. What does "normal" even mean in a rapidly warming environment? Well, that probably depends on your perspective. #Arctic#ClimateChange @Climatologist49

A sure sign that contemporary 30-year climate normals are not keeping up with the rate of Arctic change: only one year (2021) since the early 1990s has less than half of land area in the Arctic (north of 60ºN) had annual average temperature above “normal", and eight years more than 90 percent of Arctic Lands were warmer than “normal". In an unchanging climate, this would bounce around 50% each year. #Arctic#ClimateChange
