The Intergovernmental Panel on Climate Change released its
Climate Change 2013: The Physical Science Basis
Friday. The 2,000-page report of Working Group I's fifth assessment
(AR5) since 1990 makes it clear that those who have denied and continue
to deny that human-caused global warming is happening have accomplished
just one thing in their lying attacks on science: slowed attempts to do
something about the climate crisis. Scientists who reviewed a boat-load
of peer-reviewed journal articles for the IPCC assessment
raised their level of certainty that humans are causing global warming from the 90 percent of the fourth assessment published in 2007 to 95 percent now:
In their starkest warning yet, following nearly seven years
of new research on the climate, the Intergovernmental Panel on Climate
Change (IPCC) said it was "unequivocal" and that even if the world
begins to moderate greenhouse gas emissions, warming is likely to cross
the critical threshold of 2C by the end of this century. That would have
serious consequences, including sea level rises, heatwaves and changes
to rainfall meaning dry regions get less and already wet areas receive
more.
In response to the report, the US secretary of state, John Kerry,
said in a statement: "This is yet another wakeup call: those who deny
the science or choose excuses over action are playing with fire."
