Climate sceptics are lessening public concern about global warming

In a briefing at the Royal Society in London on October 10th, Dr Hansen, who heads NASA's Goddard Institute of Space Studies, and is widely thought of as "the father of global warming" – his dramatic alert about climate change in US Senate hearings in July 1988 put the issue on the world agenda, was frank about the success with public opinion of the climate sceptics ,whom he termed "the climate contrarians", in effectively lessening public concern about global warming.
I think that the actual economic crisis is helping the sceptics in their battle.In spite that the greenhouse gases (GHG) emissions have increased 45% since Kyoto protocol in 1990 and the extreme climatic phenomenos that we have seen in this period.The target agreed upon was an average reduction of 5.2% from 1990 levels by the year 2012.Unfortunately,for economic reasons,carbon is everyday widely more used increasing GHG emissions and so global warming,especially in China, who became the first responsable for GHG emissions in the world followed by USA.
Part of the problem, Hansen said, was that the climate sceptic lobby employed communications professionals, whereas "scientists are just barely competent at communicating with the public and don't have the wherewithal to do it."
When he was asked if anything might re-alert the public to the dangers of climate change, Dr Hansen said: "Mother Nature."
Significant climatic "extreme events" were now occurring over 10 to 15 per cent of the planet annually, whereas between 1950 to 1980 they occurred over less than 1 per cent. He added: "So in places like Texas this year, Moscow last year, and Europe in 2003, the climate change is so big that they are undeniable. Within 10 to 15 years they're going to occur over 15 to 20 per cent of the planet, so people have to notice that the climate is changing."
Hansen's evidence that the world is warming

Texas, summer 2011
The US state this year has had its driest summer since record-keeping began in 1895, with 75 per cent of the state classified as "exceptional drought", the worst level. Shortages of grass, hay and water have forced ranchers to thin their herds – where this cow died, in the San Angelo area, there has been less than three inches of rain.
Moscow, August 2010
Russia experienced its hottest-ever summer last year – for weeks, a large portion of European Russia was more than 7 °C (12.6 °F) warmer than normal, and a new national record was set of 44 °C (111 °F). Raging forest fires filled Moscow with smoke, forcing the cancellation of air services and obliging people to don face masks.
Northern Europe, 2003
Shrivelled French grapes at the end of Europe's hottest summer on record, in 2003. The heatwave led to health crises in several countries and more than 40,000 people are thought to have died. Britain experienced its first (and so far only) 100+ F air temperature – 101.3°F (38.5°C) recorded at Brogdale, Kent, on 10 August.
