Half a degree matters to curb disaster risk

The difference between 1.5°C and 2°C of global warming may not seem significant. But research shows that failing to limit global warming at 1.5°C above pre-industrial levels will significantly increase disaster risk.

The annual mean global temperature is likely to be at least 1° Celsius above pre-industrial levels (1850-1900) in each of the coming five years (2020-2024).

New research finds that reducing climate change is expected to cost much less than the damage that climate impacts will inflict on people, infrastructure and ecosystems.

New research is the first to show that the persistence of warm, dry and rainy periods would increase in Europe, North America and Asia under 1.5°C and 2°C of warming.

Human-induced climate change poses a major threat to the reliable water supply in many highly populated regions. Here, the authors of this report combine hydrological and climate model simulations to evaluate risks to the water supply under projected

The increase in surface air temperature in China has been faster than the global rate, and more high temperature spells are expected to occur in future. Here, the authors assess the annual heat-related mortality in densely populated cities of China at 1.5

Unless global warming can be limited to below 2°C, more than half the world could see new heat records every year until the end of the century.
