"Dyson may be an Obama-loving, Bush-loathing liberal who has spent his life opposing American wars and fighting for the protection of natural resources, but he brooks no ideology and has a withering aversion to scientific consensus. The Nobel physics laureate Steven Weinberg ...[text shortened]... h of a conformist. Consensus is not a good way to judge science. Facts are the basis of science.
Facts are indeed the basis of science.
And the reason that 97% of scientists and science papers on the topic agree
that the world is warming, and that we are the cause via greenhouse gas
emissions is that the facts support this.
There are many many strands of evidence, but one that is frequently overlooked
and is to me one of the most compelling is this.
We have satellites in orbit that can and do measure the amount of energy that
the Earth is receiving from the Sun, and the amount of energy the Earth is radiating
back into space. For the Earth's climate to be stable, for temperatures to be stable
the amount of energy the Earth radiates should equal the amount it absorbs.
If the amount it receives is less than that it radiates then it is loosing energy
and cooling. If the amount it receives is greater than that it radiates then it is
gaining energy and warming.
And the measurements we get indicate that on average the Earth is absorbing a
few watts per square meter extra energy over what it is radiating back out.
Which totals up to something in the region of 12 Hiroshima bombs worth of energy gain
per second over the entire planet. The vast majority of which goes into warming the oceans.
This is consistent with our measurements of energy gain by measuring the temperature of
the oceans and atmosphere. As well as the energy required to melt the glaciers and
ice-sheets that are melting the world over. [And Antarctica is net loosing ice, not gaining it]
And what is more the satellites tell us WHAT is making the world warm up.
By measuring the spectrum of Earth's radiation at the surface and from space we can see
which molecules in the atmosphere are absorbing the energy and retaining the heat.
This coupled with the fact that observations match up with theoretical predictions and that
climate models and predictions that produce global warming are vastly more accurate than
the predictions and models of deniers, means that the consensus is overwhelmingly likely
to be right.
The world is warming, We are responsible, And the results of warming will be bad from both
an economic and humanitarian as well as environmental standpoint.
