The weather service ranks heat as the deadliest weather hazard. US death certificates for 1999–2024 list cold in 45,301 deaths and heat in 23,951. The gap has narrowed: in 2023 heat reached 95% of cold.

Since November 2022, ADP payroll data shows US software developers aged 22 to 25 down almost a fifth and those aged 26 to 30 down 4%, while every group over 30 grew. Developer job ads are 18% below pre-pandemic levels. Data to October 2026.

The IEA counts more than 20 million electric cars sold in 2025, up 20%. Tesla delivered 1.64 million, its second yearly fall. Its 2026 deliveries to September are 8.8% up, level with 2023, but third-quarter deliveries fell 2.1%.

Arctic sea ice shrank to 4.60 million km² on 12 September 2026, tied for 10th lowest in 48 years of satellite records, according to NSIDC. All 20 of the lowest minimums came in 2007–2026; the winter maximum, 14.29 million km² in 2026, tied with 2025's for the lowest.

The Global Carbon Budget 2026 projects that China's fossil CO2 emissions will fall 0.9% this year, after two years of almost no growth. Its range runs from a 2.6% fall to a 0.8% rise, and twice since 2015 a fall it projected for China turned out to be a rise, so one projected fall does not establish a peak.

Energy accounted for almost all (99.8%) of the rise. It made up 6.4% of the CPI basket in September 2025 but 36.2% of September 2026's 3.7% inflation rate; everything else added 2.38 percentage points, as in February, down from 2.84 a year earlier.

The US had 5,182 confirmed measles cases in 2026 by 5 November, according to CDC data, the most in a year since 1991 and more than twice 2025's 2,289. A PAHO commission is meeting on 10–13 November to review whether the US has lost its measles elimination status.

In 2025 solar generated more electricity than wind for the first time in this 1985–2025 series, and solar and wind together accounted for 99.7% of the net increase in world generation while fossil generation was roughly flat.

2026 would need an October–December anomaly 0.17–0.18°C above the warmest previous final quarter to overtake 2024 in this monthly ERA5 calculation.

If no French household could keep more than €10 million, the fortunes above that line would be worth almost half of GDP. Two-thirds of it belongs to just 153 families.

If no American could keep more than $10 million, the fortunes above that line would be worth about 60% of GDP. The money matters less than you'd think, and the power matters more.
