The global temperature anomaly versus 1991-2020 has risen strongly recently, from +0.21°C on July 4, 2025, to +0.83°C on September 19, 2025, raising fears that a temperature rise could be triggered that could drive humans into extinction soon. arctic-news.blogspot.com/2025/09/el-n...

The global surface air temperature anomaly has risen strongly, from +0.21°C to +0.73°C (Jul 4 to Sep 18, 2025), raising fears that feedbacks and a 2026 El Niño could trigger a temperature rise of more than 3°C with the potential to cause humans to go extinct. arctic-news.blogspot.com/2025/09/el-n...

Antarctic sea ice area anomaly during a period when very little sunlight reaches the Southern Hemisphere. Yet, Antarctic sea ice area has been very low recently. Note also that this very low anomaly has been reached in the absence of an El Niño. arctic-news.blogspot.com/2025/09/doub...

The temperature anomaly (vs 1991-2020) has risen from +0.21°C on July 4, 2025, to +0.73°C on September 17, 2025, which could indicate that acceleration of the temperature rise is overwhelming the temperature suppression that comes with a move into La Niña. arctic-news.blogspot.com/2025/09/el-n...

The sea surface temperature anomaly keeps rising, in particular from the latitudes of 30° and higher north. arctic-news.blogspot.com/2025/09/el-n...

As temperatures rise, Sudden Stratospheric Warming events can move water vapor into the stratosphere, while more water vapor gets into the air and more precipitable water can reach the Arctic and Antarctica, as illustrated by this forecast for Sept. 23, 2025. arctic-news.blogspot.com/p/sudden-str...

This image shows that relative humidity as high as 35% is forecast over Antarctica at 70 hPa, which is in the lower stratosphere corresponding with an altitude of approximately 20 km. arctic-news.blogspot.com/p/sudden-str...

The temperature anomaly (vs 1991-2020) has risen from +0.21°C on July 4, 2025, to +0.72°C on Sept. 15, 2025, which could indicate that acceleration of the temperature rise is overwhelming the temperature suppression that comes with a move into La Niña. arctic-news.blogspot.com/2025/09/el-n...

Arctic sea ice volume was at a record low for the day on September 15, 2025, as it has been for more than a year. arctic-news.blogspot.com/2025/09/arct...

The temperature anomaly on land fell from 2.93°C in Jan 2025 to 1.45°C in Jul 2025, in line with the suppression that comes with a La Niña, but the anomaly rose to 1.82°C in Aug 2025. Could a 2026 El Niño trigger a rise of 3°C and cause humans to go extinct? arctic-news.blogspot.com/2025/09/el-n...

On September 12, 2025, the temperature reached an anomaly of -0.52°C versus 1991-2020 in Niño 3.4, an area in the Pacific (inset) that is critical to the development of El Niño, indicating that La Niña conditions are likely to dominate late 2025/early 2026. arctic-news.blogspot.com/2025/09/el-n...

Arctic sea ice thickness on September 11, 2025. Sea ice thickness can be hard to measure, due to rain and meltwater forming pools on top of the ice, while clouds can also obscure satellite imaging. arctic-news.blogspot.com/2025/09/arct...
