Half a degree of warming doesn\u2019t sound like much. But there is fresh evidence that it could make a huge difference to rainfall and drought.<\/strong><\/p>\n\n\n\n

LONDON, 4 April, 2019 \u2212<\/em> Japanese scientists have found new evidence that a global average temperature rise as small as half a degree could have a drastic effect.<\/p>\n\n\n\n

They conclude that the world cannot afford to delay action to reduce greenhouse gas emissions and slow global warming to 1.5\u00b0C by 2100 \u2013 the \u201cideal target\u201d enshrined in the promise by 195 nations to limit warming to well below 2\u00b0C above the long-term average for most of human history.<\/p>\n\n\n\n

The evidence is this: a shift of even 0.5\u00b0C could make a dramatic difference<\/a> to the risks of devastating droughts and calamitous floods.<\/p>\n\n\n\n

If governments keep to the letter of the Paris Agreement of 2015 but not the spirit<\/a>, and let warming rise to the maximum of 2\u00b0, then there will be more intense rainfall across North America, Europe and Asia, and more intense droughts around the Mediterranean.<\/p>\n\n\n\n

And although the average intensity of each flood or drought would increase measurably, the intensity of the most extreme event could be even more intense: 10 times greater. That is: the worst imaginable floods 80 years from now would be ten times worse than the worst today.<\/p>\n\n\n\n

\u201cSuch drastic changes between flood and drought conditions pose a major challenge . . . risks could be substantially reduced by achieving a 1.5\u00b0C target\u201d<\/strong><\/p><\/blockquote>\n\n\n\n

At the heart of research like this is a new way of looking at future climate projections devised \u2013 by researchers all over the world \u2013 on a range of possible outcomes for a planet that has recognised climate change, vowed to respond, but failed to take sufficiently energetic steps.<\/p>\n\n\n\n
