The article you cited also says:
"There are three things on which almost all climate scientists are
now agreed. The first is that man-made climate change is real. The
second is that we need to take action. The third is that, to avert
catastrophic effects on both humans and ecosystems, we should seek to
prevent global temperatures from rising by more than 2C above pre-
industrial levels.

Two degrees is the point at which some of the most dangerous
processes catalysed by climate change could become irreversible. This
includes the melting of the west Antarctic and Greenland ice sheets,
which between them could raise global sea levels by seven metres. It
includes the drying out of many parts of Africa, and the inundation
by salt water of the aquifers used by cities such as Shanghai,
Manila, Jakarta, Bangkok, Kolkata, Mumbai, Karachi, Lagos, Buenos
Aires and Lima. It also means runaway positive feedback, as the
Arctic tundras begin to release the methane they contain, and the
Amazon rainforest dies off, turning trees back into carbon dioxide.
In other words, if the planet warms by 2C, 3C or 4C becomes almost
inevitable."

and

"But to use this as an excuse for inaction is like remaining on a
railway track while the train is hurtling towards you. We might not
have time to jump out of the way, but if we don't attempt it, the
disaster is bound to happen. If we in the United Kingdom are to bear
our fair share of dealing with climate change, we must cut our
emissions by 87% in 24 years."

So Dan, do we do nothing and hope beyond hope that our scientists are
wrong?  What is the cost of doing nothing?
