Copenhagen prelude.
Wednesday, December 9th, 2009An indicative map of potential consequences of global warming, by the NYT. The provincially patriotic among us should pay attention to that yellow spot in the Mediterranean that will be affected from droughts. Surprise: it’s the south of Greece. And then in frame 3, it’s all about Cyprus.
Moreover:
From Cosmic Variance:
You can find scientists that believe the Universe is not expanding. They are wrong. You can find scientists that believe there is no evidence for evolution. They are wrong. And you can find scientists that believe there is no evidence for anthropogenic global warming. They are wrong.
and then
Since this issue has profound consequences for centuries to come, I would claim it is the responsibility of every citizen of the world to educate themselves on the topic. It seems to me that each of us has three straightforward choices:
1. go back to school, get a PhD in climate sciences, and form one’s own informed opinions about what’s going on.
2. trust the experts.
3. trust the fringe.Note that the fringe consists almost entirely of non-experts. And believing the fringe requires you to be convinced there’s a vast scientific conspiracy, with the willing collusion of thousands of experts around the world. With no obvious motive or agenda.
From Andrew Jaffe’s leaves on the line
The basic science behind climate change is well-understood:
1. The mean temperature is increasing, with significant variation superposed from place to place and year to year.
2. This is caused largely by the anthropogenic increase in carbon dioxide and other greenhouse gases in the atmosphere, due to the very well-understood and uncontroversial physics of the carbon-dioxide molecule.
3. Significant further increase would be societally bad for many people.
4. Lowering our greenhouse-gas emissions can slow or halt the increasing temperatures.At this coarse level, both the data and the theory underlying these conclusions are almost incontrovertible and ought to be uncontroversial, although each of these has been questioned by the
politically-motivated or ignorant denierssceptics.
