Uncertainty Part One: Climate and Loaded Dice

Here’s a little different slant on the old subjects of climate change and coronal mass ejections.
Climate: the Known Unknowns

Will the Earth be hotter in 2050 than today?  What does the science say?

The simplest answer is, probably.  A more complicated answer is, we don’t know.

We do know it is almost certain, that absent a 50% drop in carbon emissions within the next ten years, and a still steeper drop afterwards, Earth’s temperature will continue to rise dangerously fast on account of the enormous quantities of carbon dioxide we have already pumped into the atmosphere. But a 50% drop in ten years would be ruinous to the global economy and is, if not technically impossible, then politically so—even more the case now that the leaders of the world’s second worst carbon polluter have turned their backs on mitigation, and even adaptation. Furthermore, even a 50% drop leaves 50% still going, with the promise of (net) zero emissions still decades away.
