Despite my scepticism of medis articals on many subjects I reprint and link this artical. It seems well sourced.
We're ruining Earth, scientists warn

DROUGHTS will be longer, flooding rains will be rarer but heavier. Cyclones will hit harder. Violent storms and extreme heatwaves will strike more frequently. Evaporation will suck up scarce inland water. Sea levels will creep up half a metre. Oceans will be so acidic that in some places shells and reefs will dissolve.
And humanity, not nature, will be to blame.
This is the assessment of the state of the planet according to what is possibly the most reviewed document in history.
Containing contributions from 2500 scientists, citing 6000 reports and reviewed by 750 experts operating under a United Nations banner, the first part of the report will be released on Friday after line-by-line consensus is reached on its conclusions.
WHAT THE DRAFT UN REPORT SAYS
■It is more than 90 per cent certain that human activities have caused global warming.
■Global temperatures will rise by 2 to 4.5 degrees.
■Earth will be increasingly unable to absorb rising carbon dioxide.
■Sea levels could rise by between 20cm and 60cm in the next 100 years, and will continue to rise for 1000 years.
■Snow will vanish from all but the highest peaks.
■More extreme, violent weather.
