Is there anyone on this forum that thinks there's no global warming? Anyone????Anyone who thinks there is no global warming is either blind or stupid.
You're kidding, right? You don't seriously mean that they're still trying to push that bit of fraud, come on! That was debunked years ago. 1000 years ago was much warmer than now, or have you forgotten the Medieval Climate Optimum?Over the last 100 years, the average temperature of the air near the Earth´s surface has risen a little less than 1° Celsius (0.74 ± 0.18°C, or 1.3 ± 0.32° Fahrenheit). Does not seem all that much? It is responsible for the conspicuous increase in storms, floods and raging forest fires we have seen in the last ten years, though, say scientists.
Their data show that an increase of one degree Celsius makes the Earth warmer now than it has been for at least a thousand years.
Out of the 20 warmest years on record, 19 have occurred since 1980. The three hottest years ever observed have all occurred in the last ten years.
Funny how the US is so much cooler than the rest of the world
Ten Hottest Years (U.S.):

Since most of the warming occured in the first half of the 20th century, before massive human emission, it's a good bet man isn't responsible. Since the climate has stopped warming for 10 years now when CO2 levels are much higher than the first half of the 20th century, it's a good bet that neither man nor CO2 is responsible. Since temperature increase does not track well with CO2 levels, but do track well with variations in solar activity, it's a good bet that neither man nor CO2 is responsible. Since mans emissions are only 3% of total global emissions it's not a good bet that man is responsible. And on and on....Since man has pumped seven or eight trillion of tons of greenhouse gasses into the atmosphere over the last couple hundred years, it is a good bet that man is responsible.
