Greece, Italy, Spain, Portugal, France and Morocco experienced extreme heat in July 2024, causing at least 23 fatalities, widespread wildfires and bringing public life to a hold.

Crippling heat is everywhere. Billions of people around the world are wilting under increasingly severe heatwaves driven largely by a fossil-fuel charged, human-induced climate crisis. More than 70 per cent of the global workforce – 2.4 billion people – are now at high risk of extreme heat. The most vulnerable communities are hit hardest.

Temperatures reach 45C in parts of the country and 225 people seek treatment for heatstroke

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.

Research shows climate change carries greater risks for unborn babies than previously thought. Some of the alarming effects of global warming may include worsening health and wellbeing in later life.

Sudden cut in pollution in 2020 meant less shade from sun and was ‘substantial’ factor in record surface temperatures in 2023, study finds

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.

Human-caused climate crisis brought soaring temperatures across Asia, from Gaza to Delhi to Manila

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

Exclusive: Planet is headed for at least 2.5C of heating with disastrous results for humanity, poll of hundreds of scientists finds

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.

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.

Evidence shows a continuing increase in the frequency and severity of global heatwaves1,2, raising concerns about the future impacts of climate change and the associated socioeconomic costs3,4. Here we develop a disaster footprint analytical framework by integrating climate, epidemiological and hybrid input–output and computable general equilibrium global trade models to estimate the midcentury socioeconomic impacts of heat stress. We consider health costs related to heat exposure, the value of heat-induced labour productivity loss and indirect losses due to economic disruptions cascading through supply chains. Here we show that the global annual incremental gross domestic product loss increases exponentially from 0.03 ± 0.01 (SSP 245)–0.05 ± 0.03 (SSP 585) percentage points during 2030–2040 to 0.05 ± 0.01–0.15 ± 0.04 percentage points during 2050–2060. By 2060, the expected global economic losses reach a total of 0.6–4.6% with losses attributed to health loss (37–45%), labour productivity loss (18–37%) and i

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

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.

James Hansen says limit will be passed ‘for all practical purposes’ by May though other experts predict that will happen in 2030s

The effect of increasing the concentration of atmospheric carbon dioxide (CO2) on global average surface air temperature might be expected to be constant, but this is not the case. A study published in the journal Science shows that carbon dioxide becomes a more potent greenhouse gas as more is released into the atmosphere.
