A new study concludes that our planet is dimming, a response likely due to rising temperatures. Warmer oceans seem to be generating fewer bright clouds, in turn less sunlight is reflected back into space – a feedback. Measurements of data spanning two decades, of the reflectance or albedo of Earth based on the earthshine that illuminates the Moon…
Discovery: Process of ice mélange thinning suggests Antarctica’s ice-shelves could retreat Decades Earlier
Ice shelves buttress glaciers – a new mechanism involving rift dynamics suggests ice shelfs could retreat faster than previously modeled. SciTechDaily: “The thinning of the ice melange that glues together large segments of floating ice shelves is another way climate change can cause rapid retreat of Antarctica’s ice shelves,” said co-author Eric Rignot, UCI professor…
Poland announced in 2020 a long term plan for phasing out coal by 2049. Coal has become increasingly expensive to mine in Poland, the industry now relies on government subsidies, taking nearly all of the annual €1.6 billion government energy sector support. Poland accounts for 30% of the European Union’s annual consumption of coal As…
Keynote speech at gridXdays – the conference on energy, sustainability and technology presented by gridX – from climate scientist and communicator, Stefan Rahmstorf. At the current rate we will pass 1.5 °C warming before 2040, but with decisive action we can still prevent this.
These results indicate that climate tipping is an imminent risk in the Earth System. Even the safe operating space of 1.5 or 2.0 degrees above present generally assumed by the IPCC might not be all that safe. According to the precautionary principle, we must consider abrupt and irreversible changes to the climate system as a real risk – at least until we understand these phenomena better.
In recent months scientists noticed that many climate models were not prepared for the real world developments manifesting now as the climate changes.
Like other countries, we feel the risks and threats in this area… We need to put aside political and other differences and not turn the transition to carbon neutrality into an instrument of unfair competition.
This heat has rapidly melted any snow remaining on the ground and has caused the thawing of the top layer of the permanently frozen soil. The water from the thaw is unable to percolate down through the frozen layers below. That causes even more thawing.
