The Earth is Melting and We Can’t Stop it Now

You can sign up for as many “clean air” initiatives as you want; it won’t help.

Sure it will help you asleep at night knowing you are “part of the solution not the problem” and I am in no way against trying to make the world a “greener” place to live for my kid.

However new studies show that no matter what we do, no matter how much pollution we stop pumping into the air…the damage has been done.

(Reuters) – Rising sea levels cannot be stopped over the next several hundred years, even if deep emissions cuts lower global average temperatures, but they can be slowed down, climate scientists said in a study on Sunday.

The Rise in sea level can’t be stopped

“Even with aggressive mitigation measures that limit global warming to less than 2 degrees above pre-industrial values by 2100, and with decreases of global temperature in the 22nd and 23rd centuries … sea level continues to rise after 2100,” they said in the journal Nature Climate Change.

This is because as warmer temperatures penetrate deep into the sea, the water warms and expands as the heat mixes through different ocean regions.

Even if global average temperatures fall and the surface layer of the sea cools, heat would still be mixed down into the deeper layers of the ocean, causing continued rises in sea levels.

If global average temperatures continue to rise, the melting of ice sheets and glaciers would only add to the problem.

The scientists calculated that if the deepest emissions cuts were made and global temperatures cooled to 0.83 degrees in 2100 – forecast based on the 1986-2005 average – and 0.55 degrees by 2300, the sea level rise due to thermal expansion would continue to increase – from 14.2cm in 2100 to 24.2cm in 2300.

So sleep easy tonight knowing that the sea levels are rising, there is nothing you can do about it except maybe buy a boat.
