Government backs temperature report
A UN report which said scientists are 95 per cent sure that mankind is causing rising global temperatures has been welcomed by the Welsh Government and academics.
The latest assessment by the Intergovernmental Panel on Climate Change, published yesterday, said global temperatures were likely to rise by 0.3C to 4.8C by 2100 depending on how much Government controlled carbon emissions. It also said levels of greenhouse gases carbon dioxide, methane and nitrous oxide were at levels "unprecedented in at least the last 800,000 years", and that sea levels were expected to rise a further 26cm to 82cm by 2100. It said an observed pause in warming over the past 15 years was too short to reflect long-term trends.
Alun Davies, Minister for Food and Natural Resources, said: "The warming of the climate system since the 19th Century is indisputable and the report shows that much of the recent warming has been caused by human activity."
Professor James Scourse, director of Climate Change Consortium of Wales, said the science was uncertain in some areas but added: "The picture is still one of a climate system heading for profound changes that will affect health, resources and potentially migration on a global level."
