New World Bank climate report: the world Is locked into ~1.5°C warming and risks are rising

new report exploring the impact of climate change in Latin America and the Caribbean, the Middle East and North Africa, and Eastern Europe and Central Asia and finds that warming of close to 1.5°C above pre-industrial times is already locked into the Earth’s atmospheric system by past and predicted greenhouse gas emissions. Without concerted action to reduce emissions, the planet is on pace for 2°C warming by mid-century and 4°C or more by the time today’s teenagers are in their 80s.

The report warns that as temperatures rise, heat extremes on par with the heat waves in the United States in 2012 and Russia in 2010 will become more common. Melting permafrost will release methane, a powerful greenhouse gas that will drive more warming in a dangerous feedback loop. Forests, including the Amazon, are also at risk. A world even 1.5°C will mean more severe droughts and global sea level rise, increasing the risk of damage from storm surges and crop loss and raising the cost of adaptation for millions of people.

Turn Down the Heat: Confronting the New Climate Normal is the third in a series of reports commissioned by the World Bank Group from the Potsdam Institute for Climate Impact Research and Climate Analytics. The first report looked at risks globally if the world were to warm by 4°C. The second report focused on three regions – Africa, South Asia, and South East Asia – and the risks to food security, water security, and low-lying cities exposed to dangerous sea level rise and vulnerability to storms.
