An IGCC report warns Earth could cross the 1.5 degree Celsius warming threshold within four years as heat accumulation in the climate system reaches record levels

Earth's climate system is accumulating heat at an accelerating rate as human activity pushed global warming to 1.37 degrees Celsius last year, with the figure projected to surpass the Paris Agreement threshold of 1.5 degrees in about four years, strong and consistent evidence shows, researchers have said. Record-high greenhouse gas (GHG) levels, combined with a continued drop in sulphur aerosols -- thereby unmasking a part of the GHGs' warming effect -- are driving human-induced warming, which remains at an all-time high of around 0.27 degrees Celsius per decade, an international team of more than 70 scientists from 56 institutions across 17 countries, including the UK, the US, India and in Europe, said. There is evidence that carbon dioxide emission growth is slowing, but society needs to massively increase decarbonisation efforts during this critical decade, the researchers said. They added that the rate at which heat is accumulating in the Earth system suggests high levels of ...

Hot and humid conditions prevailing during India's monsoon season could extend the duration of uncompensable heat stress of the summer season under a global warming of 2 degrees Celsius, a study has found. Findings published in the journal American Geophysical Union (AGU) Advances highlight a "surge of UHS (uncompensable heat stress) during the monsoon season (July-October) as the climate warms". Researchers from the Indian Institute of Technology (IIT) Gandhinagar and the US' Stanford and Purdue universities said long-lasting uncompensable heat stress across both the seasons -- summer and monsoon -- could pose critical challenges to public health, labour productivity, and climate resilience in densely populated and vulnerable regions. Uncompensable heat stress occurs when one's body is unable to cool down through sweating or other mechanisms due to extreme heat and humidity. A sustained accumulation of heat can endanger human health, including causing heat-related illness, organ .

From climate change to concrete heat traps, rising night-time temperatures are reducing cooling hours and making heatwaves more dangerous across Indian cities

New research finds airborne microplastics trap heat and may amplify global warming, challenging earlier assumptions about their climate impact

As heat intensifies, dengue is spreading faster and reaching new regions, with climate change reshaping transmission patterns and increasing global health risks

The number of days when the weather gets hot, dry and windy - ideal to spark extreme wildfires - has nearly tripled in the past 45 years across the globe, with the trend increasing even higher in the Americas, a new study shows. And more than half of that increase is caused by human-caused climate change, researchers calculated. What this means is that as the world warms, more places across the globe are prone to go up in flames at the same time because of increasingly synchronous fire weather, which is when multiple places have the right conditions to go up in smoke. Countries may not have enough resources to put out all the fires popping up and help won't be as likely to come from neighbours busy with their own flames, according to the authors of a study in Wednesday's Science Advances. In 1979 and for the next 15 years, the world averaged 22 synchronous fire weather days a year for flames that stayed within large global regions, the study found. In 2023 and 2024, it was up to mor

Global warming is increasing water demands and makes the natural supply of water less predictable

Because worldwide emissions continue to rise, the past 11 years have all been among the 11 hottest, and the hottest 25 years have all occurred since 1998

India recorded its eighth warmest year in 2025 since 1901, with extreme weather events killing 2,760 people, while the IMD forecast below-normal rains and colder days ahead in early 2026

India is the world's third-largest emitter of methane but lacks clear policy direction and mechanisms to track and mitigate the gas, which is far more potent than carbon dioxide in global warming

Minister urges industry to invest in rare earth magnet manufacturing to boost green tech and EV value chains

Despite dramatic scenes in Belem, the summit delivered little on climate finance, fossil fuel transition or equity, leaving India and other developing nations disappointed

The UN has warned that the world has missed its target to keep global warming in line with 1.5 degrees Celsius above pre-industrial levels

India's average temperature rose by nearly 0.9 degrees Celsius in the last decade (2015-2024) with the number of warm days increasing across most of the country, a new study says, highlighting the urgent need for adaptation strategies. The hottest day of the year also registered a temperature rise of 1.5-2 degrees Celsius in western and northeast India since the 1950s, the study found. The research by climate scientists Chirag Dhara (Krea University, India), Aditi Deshpande (Savitribai Phule Pune University), Roxy Mathew Koll (Indian Institute of Tropical Meteorology), Padmini Dalpadado (Institute of Marine Research, Norway) and Mandira Singh Shrestha (International Center for Integrated Mountain Development, Nepal), states that this warming is driving a surge in extreme weather events. The new peer-reviewed study synthesises the latest observational data and climate model projections to paint a stark picture, the researchers said. "India's average temperature has risen by nearly 0

Due to lack of willingness on part of developed nations to open their purses, ambitions have turned to phasing out fossil fuels, in order to keep global warming below 1.5°C over pre-industrial levels

With climate impacts mounting, the summit's final days must deliver a credible finance plan, realistic transition pathways and stronger action-focused alliances

Recent studies have estimated climate finance requirements of EMDEs at $1-4 trillion per year up to 2030, which is seen as daunting, leading to even less action than might have been possible

The reluctance of developed nations like the UK to foot the climate bill and the US withdrawal among key challenges to mobilise $1.3 trillion by 2035

This much was evident when it became clear that only a third of countries, ahead of the summit, submitted updates detailing how they would cut the emission of greenhouse gases
