The World Out There-Global Warming or Global Warning ?

 If the world does not minimize pollution of heat-trapping greenhouse gases, the already noticeable effects of global warming could spiral "out of control" the head of a UN scientific panel warned on Monday.

   One of the research's authors,Maarten van Aalst, a top official at the International Federation of the Red Cross and Red Crescent Societies, said, ? If we don?t reduce greenhouse gases soon, risks will get out of hand. And the risks have already risen.?

   Twenty-first century calamities such as fatal heat waves in Europe, wildfires in the United States, famines and droughts in Australia and lethal flooding in Mozambique,Thailand and Pakistan accentuate how susceptible mankind is to severe weather, as per the report from the Nobel Prize-winning group of scientists.The hazards are going to aggravate as the climate crisis worsens even more, the report?s authors said. ?We?re now in an era where climate change isn?t some kind of future hypothetical,? said the overall lead author of the report, Chris Field of the Carnegie Institution for Science in California. ?We live in an area where impacts from climate change are already widespread and consequential.? Nobody is immune,the scientists reported.            

    Post several days of late-night wrangling, more than 100 governments unanimously approved the scientist-written 49-page summary — which is aimed at world political leaders. The summary mentions the word ?risk? an average of about 5 1/2 times per page. ?Changes are occurring rapidly and they are sort of building up that risk,? Field said. These dangers are both major and minor, as per the report. They are now and in the future. They strike humanity from peasants to huge metropolitans.

    Some areas will have excess water, some with scarcity of water, including drinking water. Other hazards mentioned in the report involve the price and availability of food, and to a lesser and more qualified extent some diseases, financial costs and even world peace. The report anticipates that the highest level of risk would first hit flora and fauna, both on land and the acidifying oceans. Climatic change will worsen complications that the community already has, such as poverty, sickness, violence and refugees, according to the report. And on the other hand, it will behave as a brake slowing down the advantages of a modernising society, such as regular economic growth and more effectual crop production, it says. ?In recent decades, changes in climate have caused impacts on natural and human systems on all continents and across the oceans,? the report says.
