The UN’s Intergovernmental Panel on Climate Change (IPCC) will this week to release a major report that is expected to warn of catastrophic consequences to food supplies, livelihoods, health and security across the world if climate change is allowed to continue unchecked.
Leaked versions of the report, published in Japan on Monday, warn that changing temperatures, droughts and heatwaves will threaten food supplies and human health, while hundreds of millions of people will be affected by coastal flooding.
Climate change will cause economic losses, make poverty worse and increase migration and risks of violent conflict. It will also harm wildlife and habitats, the study by experts from around the world is expected to say.
In Europe, heatwaves, droughts and heavy rainstorms will increase and there will be a greater risk of coastal and river flooding, it is expected to say, while heat-related deaths will also increase.
The report, which collates work by thousands of scientists from across the world, is likely to state that climate change has already left its mark on all continents and oceans, and is expected to warn that even a small rise in temperatures could lead to irreversible changes.
Williams, who stepped down as leader of the Anglican church just over a year ago, said Monday’s report put “our local problems into a deeply disturbing global context”.
