2024 was the hottest year on record [1], with global temperatures exceeding 1.5 °C above preindustrial climate conditions for the first time and records broken across large parts of Earth’s surface. Among the widespread impacts of exceptional heat, rising food prices are beginning to play a prominent role in public perception, now the second most frequently cited impact of climate change experienced globally, following only extreme heat itself [2]. Recent econometric analysis confirms that abnormally high temperatures directly cause higher food prices, as impacts on agricultural production [3] translate into supply shortages and food price inflation [4, 5]. These analyses track changes in overall price aggregates which are typically slow-moving, but specific food goods can also experience much stronger short-term price spikes in response to extreme heat.

Global temperature for 2025 should decline little, if at all, from the record 2024 level. Absence of a large temperature decline after the huge El Nino-spurred temperature increase in 2023-24 will provide further confirmation that IPCC’s best estimates for climate sensitivity and aerosol climate forcing were both underestimates. Specifically, 2025 global temperature should remain near or above +1.5C relative to 1880-1920, and, if the tropics remain ENSO-neutral, there is good chance that 2025 may even exceed the 2024 record high global temperature.

2024 marks the first time since record keeping began that all of the 10 hottest years have fallen within the most recent decade.

The temperatures of the Mediterranean Sea in recent days have reached heat records set last summer, the main Spanish maritime research center told AFP Tuesday, with marine heat waves in some places exceeding 30 degrees Celsius.

Global temperature (12-month mean) is still rising at 1.56°C relative to 1880-1920 in the GISS analysis through April (Fig. 1). [Robert Rohde reports that it is 1.65°C relative to 1850-1900 in the BerkeleyEarth analysis.[3]] Global temperature is likely to continue to rise a bit for at least a month, peak this summer, and then decline as the El Nino fades toward La Nina. Acceleration of global warming is now hard to deny. The GISS 12-month temperature is now 0.36°C above the 0.18°C/decade trend line, which is 3.6 times the standard deviation (0.1°C). Confidence in global warming acceleration thus exceeds 99%, but we need to see how far temperature falls with the next La Nina before evaluating the post-2010 global warming rate.

If the anomaly does not stabilise by August, ‘the world will be in uncharted territory’, says climate expert

Taking into account all known factors, the planet warmed 0.2 °C more last year than climate scientists expected. More and better data are urgently needed.

Rapid ocean warming and unusually hot winter days recorded as human-made global heating combines with El Niño

Extreme weather is ‘smacking us in the face’ with worse to come, but a ‘tiny window’ of hope remains, say leading climate scientists

Winter temperatures have neared 40 degrees Celsius in parts of South America, which is up to 20C higher than normal for this time of year and the equivalent of Sydney hitting 35C in the first week of August.

It’s the middle of winter in South America, but that hasn’t kept the heat away in Chile, Argentina and surrounding locations. Multiple spells of oddly hot weather have roasted the region in recent weeks. The latest spell early this week has become the most intense, pushing the mercury above 100 degrees Fahrenheit, while setting an August record for Chile.

Following a record hot June, large areas of the US and Mexico, Southern Europe and China experienced extreme heat in July 2023, breaking many local high temperature records.

Energy firms have made record profits by increasing production of oil and gas, far from their promises of rolling back emissions

Mexico and the Caribbean are experiencing the most intense heatwave in their recorded history. The Mexican Plateau is being seared by harsh dry heat, while the Caribbean contends with deadly humid temperatures. On June 12, 2023, the mercury soared above 45 °C (113 °F) in several areas, including regions of high altitude. The city of Torreón, sitting at 1 123 m (3 684 feet) above sea level, saw temperatures rise to 43.3 °C (109.94 °F) on June 12, while Durango Airport, located at 1 872 m (6 142 feet) altitude, experienced 40.4 °C (104.72 °F) heat. La Bufa, perched even higher at 2 612 m (8 570 feet) above sea level, broke all-time records with a temperature of 33.4 °C (92.12 °F).

Extreme heatwave is challenging temperature records this week. Just a day after Italy tied with its all-time national record, the same weather station in the town of Siracusa, Sicily might shatter the European highest temperature record! This afternoon, Wednesday, Aug 11th, Siracusa has reported an astonishing peak temperature of +48.8 °C (119.8 °F). Heatwave now shifts to Spain and Portugal!
