The Accelerating Climate Crisis Future

A new study by climate scientists published today affirms that the rate of global heating will increase dramatically in the very near future, and keep on increasing.  Scientific American summarizes:

"By 2020, warming rates should eclipse historical bounds of the past 1,000 years — and likely at least 2,000 years — and keep rising. If greenhouse gas emissions continue on their current trend, the rate of warming will reach 0.7°F per decade and stay that high until at least 2100.

The northern hemisphere will be the first region to experience historically unprecedented warming. The Arctic, which is already the fastest warming part of the planet, will see temperatures rise 1.1°F per decade by 2040. North America and Europe will see slightly lower, though equally unprecedented, warming.

“With those high rates of change, there’s not going to be anything close to equilibrium,” Smith said, underscoring the profound potential impacts on both the natural world and society."

  This study is independent of those that looked specifically at ocean capture of heat that probably accounts for the slow (but steady) rate increase in recent years, below what was predicted.  Those studies also conclude that there will be a compensating temperature spike in the same time frame--beginning around 2020, or before.

As these conclusions reach policymakers and the public, the pressure to deal with the consequences of the climate crisis will probably increase, but the refusal to deal with causes--to even recognize them--continues to be a barrier to addressing both consequences and causes.

Live Science chronicles some extreme instances in the US, such as Florida where an unofficial ban directed by its governor forbids even using the words "climate change," "global warming" or even "sea level rise."  There and in other coastal southern states, the fear of fall real estate prices and rising insurance costs outweighs the fear of rising waters.

 "Sea level rise" is re-branded as "nuisance flooding."  If the seas do rise to the worst case levels anticipated, Miami will be underwater by the end of the century and eventually pretty much the entire state of Florida will follow.   Quite a nuisance, at least if you live in Florida.  Some of this rise is still dependent on current and near future greenhouse gases pollution.  But if we just close our eyes real tight, it will all go away.  Though not for the grandchildren.
