Half a degree matters to curb disaster risk

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.

New research reveals that an intense decrease in greenhouse gas emissions is needed if farmers are to have time to protect their crops from excess or declining rainfall. If emissions continue at the current rate or increase, some regions will see changes as early as 2020, a striking development given that rain fed-agriculture produces most of the world's crops.

Climate extremes are widely projected to become more severe as the global climate continues to warm due to anthropogenic greenhouse gas emissions. These extremes often cause the most severe impacts on society. Therefore, the extent to which the extremes

New research suggests that the subtropical Southern Hemisphere drying trend may reverse if global temperatures stabilise in a future world with zero net greenhouse gas emissions. The reversal will occur even if emissions and temperatures do not level off until 2250 instead of 2100, though the climate will be much warmer.

This report describes an assessment of the projected future impacts of climate change, land use change and changes in water consumption on water resources for the European continent, as obtained using JRC’s LISFLOOD water resources model. For this study

A new study shows that heatwaves will worsen as the climate changes in the future, and less developed countries will likely be more affected in a 1.5°C warmer world than developed counterparts in a 2°C world. Curbing emissions can limit future warming, while providing access to water, shelter, and efficient healthcare can increase community resilience.

This study projects indicators of global heatwave risk associated with global warming of 1.5 and 2 °C, specified by the Paris agreement, for two future pathways of societal development representing low and high vulnerability conditions.

This guide aims to make the findings of the Intergovernmental Panel on Climate Change's special report on the ‘impacts of global warming of 1.5°C global greenhouse gas emission pathways' accessible to humanitarian and development practitioners and policy

As nations meet in Poland for the 24th UNFCCC Conference of the Parties, this report synthesizes recent key insights from science with focus on those published in 2017-2018. 

From fires in North America to floods across Asia, many societies have in the
