Heat waves are getting more dangerous with climate change — and we may still be underestimating them

Months of scorching temperatures sometimes over 50 degrees Celsius (122 Fahrenheit) in parts of India this year left hundreds dead or ill. Official government records put the number of heat-related deaths this year as 110, but public health experts say that number is more likely in the thousands. Poor data collection methods and reporting are stopping the country from getting a more accurate picture of how deadly the heat is. Experts are concerned that it's hindering efforts to better prepare for future heat waves.

Europe is no exception when it comes to the consequences of climate change. It is the fastest warming continent, with temperatures rising at around twice the global average rate.

An intense heat wave gripping South and South-East Asia since late March comes as no surprise to leading meteorologists who have been warning of steadily rising temperatures in the Indian Ocean.

Climate scientists have told the Guardian they expect catastrophic levels of global heating. Here’s what that would mean for the planet

Marine heat waves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas emissions, according to a study just released by Dr. Armineh Barkhordarian from Universität Hamburg's Cluster of Excellence for climate research CLICCS. Since 2007, conditions in the Arctic have shifted, as confirmed by data recently published in the journal Communications Earth & Environment. Between 2007 and 2021, the marginal zones of the Arctic Ocean experienced 11 marine heat waves, producing an average temperature rise of 2.2 degrees Celsius above seasonal norm and lasting an average of 37 days. Since 2015, there have been Arctic marine heat waves every year.

Heatwaves, wildfires and floods are just the ‘tip of the iceberg’, leading climate scientists say

Antarctica’s sea ice levels are plummeting as extreme weather events happen faster than scientists predicted

After hottest day ever, researchers say global heating may mean future of crop failures on land and ‘silent dying’ in the oceans

Abstract. The summer of 2022 was memorable and record-breaking, ranking as the second hottest summer in France since 1900, with a seasonal surface air temperature average of 22.7 ∘C. In particular, France experienced multiple record-breaking heatwaves during the meteorological summer. As the main heat reservoir of the Earth system, the oceans are at the forefront of events of this magnitude which enhance oceanic disturbances such as marine heatwaves (MHWs). In this study, we investigate the sea surface temperature (SST) of French maritime basins using remotely sensed measurements to track the response of surface waters to the atmospheric heatwaves and determine the intensity of such feedback. Beyond the direct relationship between SSTs and surface air temperatures, we explore the leading atmospheric parameters affecting the upper-layer ocean heat budget. Despite some gaps in data availability, the SSTs measured during the meteorological summer of 2022 were record-breaking, the mean SST was between 1.3 and 2.6

Electrical blackouts like the ones in California are becoming more common. So are heat waves. A new study published in the journal of the National Institute of Health attempts to predict what will happen when both occur at the same time.

It’s not that our models can’t simulate small-scale weather – they’re basically the same models we use for weather forecasting – it’s just very computationally expensive to have them zoom in and run in “weather mode” to get a highly detailed simulation.

In March, the north and south poles had record temperatures. In May in Delhi, it hit 49C. Last week in Madrid, 40C. Experts say the worst effects of the climate emergency cannot be avoided if emissions continue to rise

Chief meteorologist says extreme temperatures ‘entirely consistent’ with human-induced climate crisis

the new study has uncovered five other events around the world which were even more severe but were never reported. “The recent heatwave in Canada and the United States shocked the world. Yet we show there have been some even greater extremes in the last few decades. Using climate models, we also find extreme heat events are likely to increase in magnitude over the coming century – at the same rate as the local average temperature,”

April temperatures at unprecedented levels have led to critical water and electricity shortages

A violent bomb cyclone affecting Iceland on February 7 and 8, 2022, produced hurricane-force winds and record-breaking waves at the southern coast of the country. One of the waves reached 40 m (131 feet) and blew off the scale, making it by far the highest measured wave off the coast of Iceland and among the highest ever measured in the world.

This paper analyses how recent trends in heat waves impact heat warning systems. We performed a retrospective analysis of the challenges faced by the French heat prevention plan since 2004. We described trends based on the environmental and health data collected each summer by the French heat warning system and prevention plan. Major evolutions of the system were tracked based on the evaluations organized each autumn with the stakeholders of the prevention plan.
