Global sea ice area is currently very low, resulting in less sunlight getting reflected back into space and more heat getting absorbed at the surface instead. arctic-news.blogspot.com/2025/02/mech...

Antarctic sea ice area was 1.22 million km² on Feb 28, 2025, almost as low as the 1.05 million km² recorded on Feb 22, 2023, raising alarms that a Double Blue Ocean Event could occur in 2025, i.e. both for the Antarctic sea ice and for the Arctic sea ice. arctic-news.blogspot.com/2025/02/mech...

La Niña conditions are present. Temperatures are typically suppressed during La Niña. Nonetheless, the global surface air temperature reached 13.31°C on Feb 10, 2025, or 0.67°C above 1991-2020, according to ERA5 data. Temperatures keep rising, despite La Niña arctic-news.blogspot.com/2025/02/shou...

A temperature rise of 3°C or more in 2050 is projected in China for three scenarios. China has a well-educated population. Of global emissions, much is released in China. Some countries face even more dire prospects. Do people know? Shouldn't people be told? arctic-news.blogspot.com/2025/02/shou...

Monthly temperature anomalies have been above 1.5°C vs 1903-1924 for 19 consecutive months (July 2023 through January 2025). The anomaly is rising, red line (2-year Lowess Smoothing trend) points at a 2°C rise in 2026 (vs 1903-1924, i.e. not pre-industrial). arctic-news.blogspot.com/2025/02/shou...
