Study: Ice mass loss sensitivity to the Antarctic ice sheet basal thermal state

Accurate predictions of ice mass loss from Antarctica are crucial for sea-level rise projections. This study investigates the impact of warmer basal temperatures on Antarctic ice sheet mass balance using numerical modeling. Results show that even a small increase in basal warming could lead to increased mass loss and the destabilization of previously frozen areas.

WMO: The State of the Global Climate 2022

The World Meteorological Organization has released its annual report on the global climate for 2022, revealing record-breaking heat, melting glaciers, and rising sea levels. The report also highlights the impact of extreme weather events on populations worldwide and the urgent need for improved early warning systems. Read on for more information.

The Climate State may Tip at 1.5 or 2 C of Global Temperature Rise

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.
