Feb 2025: High pressure over the S. Atlantic brought scorching heat to South America. Rio Grande do Sul delayed school starts, while Rio de Janeiro hit 44°C (111°F)—the hottest in a decade. Check this GEOS map from Feb 17 showing temps over 38°C!

Studies predict that the #AMOC might collapse by 2050, potentially earlier. This change could lead to a significant drop in temperatures in the #UK, decreasing by 10°C on average. Such a shift could herald a new ice age for the area. Mitigation is urgent.

The heat in the tropics is currently deadly, with possible wet bulb temperatures being observed in parts of Western Africa at certain times of the day. Climate cooling mitigation is urgently needed before these regions become uninhabitable for extended periods of the year.

Dangerous heat in Brazil once again. Last year, they faced 8 severe heatwaves. This year, they’ve already endured 3—and it’s only Feb. The escalating heat crisis will have profound consequences for this country, the Amazon rainforest and the wider region.

The heat in India and Pakistan is staggering already, with some regions experiencing temperature anomalies as high as 16°C above normal. Heat seasons arrive earlier in this warming climate. In passing 1.5°C globally, the threat of lethal wet-bulb temps looms large here.

On its current trajectory, the world will experience at least 3°C of warming by the end of the century—within the lifetime of most children today.

🔥 3°C = an intolerable world, potential human extinction.

We must take urgent action to mitigate this catastrophic scenario.

While most are concentrating on the LA fires, etc., a sweltering heatwave is hitting South America. Santiago was forecasting a scorching 39°C, with surrounding areas and regions nearing 40°C and some places even higher

“Our monitoring has shown a significant increase in the area of mangroves that have lost their natural recovery capacity following recent hurricanes, such as Irma in 2017 and Ian in 2022,” said Zhe Zhu.

Here is a fantastic model illustrating the protective role of mangroves

Mangroves in #Florida are losing their resilience, but they're vital for our coasts. These thick, natural buffers protect against coastal flooding, waves, storm surges, and tsunamis. The increasing frequency and intensity of storms are threatening their resilience.

It is remarkable to observe the substantial expenditure of fossil fuel energy and carbon in constructing infrastructures that, within this century, are predicted to be submerged due to rising sea levels. A huge waste of resources and a lack of strategic foresight. #ClimateChange
