The risk of a hothouse Earth trajectory: massive, sometimes abrupt, and undoubtedly disruptive. A much less habitable state of the climate for us.

"The world is closer than thought to a “point of no return” after which runaway global heating cannot be stopped, scientists have said."

"The public and politicians were largely unaware of the risk of passing the point of no return, the researchers said. The group said they were issuing their warning because while rapid and immediate cuts to fossil fuel burning were challenging, reversing course was likely to be impossible once on the path to a hothouse Earth, even if emissions were eventually slashed."

“We know we are running profound risks on the current climate trajectory, which we can’t rule out could turn into a trajectory towards a much less habitable state of the climate for us. " >>

For this World Wetlands Day, protecting wetlands without protecting ice is only half the story. The fate of wetlands is written upstream.

I was at the Scarborough Bluffs beach today. The entire 1-km-long 100-meter-wide beach is covered with cabbage-sized frozen snowballs. Must have happened during the snowstorm. Does any one know the science behind how this happened? #meteorology #cryosphere #TorontoWeather #greatlakes #lakeontario #hydrology

Sentinel-1's decade of essential data over shifting ice sheets

Ice velocity is a key parameter in measuring the effects of #ClimateChange. The speed at which #glaciers and #IceSheets move tells us the rate at which they discharge ice and water into the sea, feeding into estimations on future #SeaLevelRise. Data on ice velocity also help to keep track of the break-up of ice sheets, such as calving events or damage to the ice sheets.
Since its first satellite was launched in 2014, the #Copernicus #Sentinel1 mission has provided a step change in the capabilities of polar satellite Earth observation. Its 12-m-long advanced #SAR instrument works in C-band. This makes it a reliable tool for acquiring high-resolution imagery for continuous monitoring and emergency response efforts. It is able to capture data through cloud cover, smoke and during lack of sunlight.

Ice flow velocity on the Antarctic ice sheet, 2014–2024. Credit: European Space Agency

The data visualization of Antarctica (see image below) shows details of ice flows moving at speeds between 1 m and 15 m per day. The Sentinel-1 data is averaged over the period 2014–2024. Regions shown on the map include the Antarctic Peninsula and Alexander Island, as well as large parts of the West Antarctic Ice Sheet and East Antarctic Ice Sheet. Most of the coastal areas were captured at either six or 12-day intervals.
On the West Antarctic Ice Sheet (on the left of the image), the Pine Island Glacier is clearly visible below the Antarctic Peninsula. Over the period of the study, the velocity of ice flow at the glacier's grounding line—the point where grounded ice detaches from the bedrock underneath it and becomes a floating ice shelf—increased continuously from approximately 10.6 m per day to 12.7 m per day. Other nearby glaciers also showed increased ice flow. These changes are caused by a range of factors including ocean-induced thinning of the floating ice shelves combined with a retreat of the grounding line.
