First, the industrial polluters pushed the line that global warming isn’t happening. Then, when science clearly established that global warming is real, the polluters said that global warming isn’t caused by human activity. Then, when a huge body of scientific research established that anthropogenic hypotheses of global warming best fit the available facts, the polluters retreated to the argument that global warming should be welcomed, making life better for humankind. Finally, since it’s become clear that the effects of global warming are causing far more human and financial harm than benefit, the polluters are saying that the rate of global warming is slowing down, so we don’t have to worry about it any more.
In response to the arguments that global warming is slowing down, we now have the following facts from the new global climate report from the World Meteorological Organization:
“The first decade of the 21st century was the warmest decade recorded since modern measurements began around 1850.”
The last decade “saw above-average precipitation, including one year – 2010 – that broke all previous records.”
In the first decade of this century, the greenhouse gases carbon dioxide, methane and nitrous oxide rose to historically record-breaking levels.
“Nine of the decade’s years were among the 10 warmest on record.”
The hottest year on record was just three years ago.
“The decade 2001– 2010 continued the upward trend in global temperatures, despite the cooling effects of multiple La Niña episodes and other natural year-to-year variability”
The five years with the lowest Arctic ice extent to date were in the first decade of this century (and the record lowest ice extent has come since, last year)
The per-decade rate of global temperature increase from the last decade of the 20th century to the first decade of the 21st century was the fastest on record, far above the average decadal rate of temperature change since 1880.
