More global warming bad news…

Found this today. It seems, according to this report, that based on current emission trends, global warming effects are set to be irreversible – over the next 1000 years (yes, one thousand) – irrespective of what mankind does to reduce his environmental footprint.

That’s bad.

Quoting from the report:

Climate change is “largely irreversible” for the next 1,000 years even if carbon dioxide (CO2) emissions could be abruptly halted, according to a new study led by the US National Oceanic and Atmospheric Administration (NOAA).

The study’s authors said there was “no going back” after the report showed that changes in surface temperature, rainfall and sea level are “largely irreversible for more than 1,000 years after CO2 emissions are completely stopped.”

… The authors emphasized that increases in CO2 that occur from 2000 to 2100 are set to “lock in” a sea level rise over the next 1,000 years.

Bad, bad, bad. Can we at least try and minimize the damage over the next 100 years?

  1. Global Warming is a natural process – cyclical sequence in which earth becomes hot before the ice age comes and then it becomes warmer again. But humans are definately accelerating the process.
    Looks like Mars is the only option. Better buy some land next to Valles Marineris when real estate is still cheap.

  2. Yes, it is natural, as you say.

    But if we push it too far artificially, we will have a danger of having a runaway greenhouse process, and end up like Venus.

    Venus now has an atmosphere of primarily CO2, and a surface temperature of 480 deg C.

    That’s not pleasant.
