We all saw Frodo arguing that Global waming was a con by the so-called leftie greenies, and that ALL the supporting evidence was a con aswell. That means the following article is proof that this con go's all the way to the US government, and that the US government is also wrong, and Frodo is right.
No doubt global warming is real: US experts
There can be no doubt that global warming is real and is being caused by people, two top US Government climate experts said.
They say industrial emissions are a leading cause, contradicting critics who argue that climate change could be caused by mostly natural forces.
"There is no doubt that the composition of the atmosphere is changing because of human activities, and today greenhouse gases are the largest human influence on global climate," Thomas Karl said, director of the US National Oceanic and Atmospheric Administration's National Climatic Data Centre, and Kevin Trenberth, head of the Climate Analysis Section at the National Centre for Atmospheric Research.
"The likely result is more frequent heat waves, droughts, extreme precipitation events, and related impacts, eg, bushfires, heat stress, vegetation changes, and sea-level rise," they added in a commentary to be published in Friday's issue of the journal Science.
They estimate that between 1990 and 2100, there is a 90 per cent probability that average global temperatures will rise by between 1.7 and 4.9 degrees Celsius because of human influences on climate.
Such dramatic warming will further melt already crumbling glaciers, inundating coastal areas.
Many other groups have already shown that ice in Greenland, the Arctic and Antarctica is melting quickly.
They noted that carbon dioxide levels in the atmosphere have risen by 31 per cent since pre-industrial times.
Carbon dioxide is the number one greenhouse gas, causing warming temperatures by trapping the Sun's energy in the atmosphere.
Emissions of sulfate and soot particles have significant effects too, but more localised, they said.
"Given what has happened to date and is projected in the future, significant further climate change is guaranteed," they wrote.
The United States has balked at signing international treaties to reduce climate-changing emissions, but the two experts said global cooperation is key.
"Climate change is truly a global issue, one that may prove to be humanity's greatest challenge," they wrote.
"It is very unlikely to be adequately addressed without greatly improved international cooperation and action."
