Research shows that fast-moving forest fires burn more severely, making it harder for forests to recover.

The devastating impacts of marine heatwaves extend far beyond dying coral reefs and declining fisheries, with new research warning these extreme ocean warming events are posing a growing threat to humans’ physical and mental health.

Researchers at IIED interviewed 175 households engaged in informal work in Dhaka, whose jobs included construction, rickshaw pulling and garment manufacturing. Exposure to extreme heat is costing Bangladeshi workers huge chunks of their pay every year.

” Compared to normal warm spells or heat waves, researchers have determined that "snow-eaters" happen when temperatures stay above freezing through both day and night for multiple days, typically three to five.

Coastal groundwater responds to sea level rise in different ways. Where the water table is free to rise with the sea, it does exactly that, rising toward the surface and increasing the risk of groundwater flooding.

Climateflation is expected to keep raising costs in the years ahead. Reducing emissions to net zero, limiting further warming and investing in climate-resilient infrastructure will be essential to ease long-term economic pressures.

As Mediterranean countries face another summer of extreme heat, research led by CMCC examines the economic costs of prolonged drought exposure.
