Earth's energy imbalance keeps rising, due to high (and rising) concentrations of greenhouse gases, other gases and warming aerosols and loss of Earth's albedo. Rising temperatures also come with feedbacks that can speed up the temperature rise acceleration. arctic-news.blogspot.com/2025/09/focu...

Polar amplification causes the temperature difference between Poles and Equator to narrow, so at times the Jet Stream can reach high latitudes and accelerate warming due to albedo loss and loss of sea ice and oceans in their capacity to act as heat buffers. arctic-news.blogspot.com/2025/10/reco...

The image shows monthly Arctic sea ice volume in the past 25 years. Markers show Apr (blue) and Sep (red) volume, corresponding with the year's maximum and minimum. In 2025, Arctic sea ice reached a record low maximum volume and a record low minimum volume. arctic-news.blogspot.com/2025/10/reco...

Methane concentrations as high as 2622 parts per billion (ppb) were recorded by the NOAA 20 satellite on September 30, 2025 am, at 399.1 mb. Note the high methane concentrations over the Arctic, over Antarctica and over the Antarctic sea ice. arctic-news.blogspot.com/2025/09/focu...

On September 27, 2025, the temperature reached an anomaly in the Niño 3.4 area of -0.67°C versus 1991-2020. The inset on the image shows the Niño 3.4 area and the sea surface temperature anomaly versus 1991-2020 that day. arctic-news.blogspot.com/2025/09/focu...

On Sep 26, 2025, temperatures reached an anomaly in the Niño 3.4 area of -0.65°C versus 1991-2020. The low temperatures in this area over the past few months indicate La Niña conditions will likely dominate in the remainder of 2025 and suppress temperatures. arctic-news.blogspot.com/2025/09/focu...

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...

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...
