Shipping lanes could open over the North Pole

[Still Waters]

By around 2050 the Arctic ice sheet will be fragile enough for icebreakers to carve a straight path between the Atlantic and Pacific oceans, the University of California claimed.

Cargo ships will be able to skirt around the North Pole without even using icebreakers because the ice will have retreated so far back.

That the curent rate of the ice melting. But if the climate changes back the ice sheets will get thick and whole again. This this not the 1st time a melting like this has happened. Just remember the Sun's cycle is about to go into a dormant cycle. DEropping the temps world wide

When in the last 2000 years has the North west passage been open ?

This has not happened in recent history and not whilst the dominent natural climate trend has been a cooling one.

Straw grapsing.

amundson sailed a ship through the northwest passage in 1903

and others in the 1940s

I stand corrected, but look at what they are actually saying - the ability to sail straight across the North Pole which has not been possible for millennia and is a different kettle of fish entirely.

speculation and soothsaying based on "computer simulations".

why should we believe models that have failed so spectacularly in all their previous predictions. as i explained before the models amplify unjustifiably co2 re radiation which is why they diverge from actual temperature observations, garbage in-garbage out.

As a previous poster pointed out correctly, the sun is going into a cool phase for the next 20 years at least, and that is based on hard science.

I'm not sure it will have much effect on global warming.

"This research shows that the most likely change in the Sun's output will not have a big impact on global temperatures or do much to slow the warming we expect from greenhouse gases,” said Gareth Jones, a climate change detection scientist with the Met Office.

Indeed, brightness will play a larger role in temperature change anyway, said Mike Lockwood, an expert in solar studies at the University of Reading.

"The 11-year solar cycle of waxing and waning sunspot numbers is perhaps the best known way the Sun changes, but longer term changes in its brightness are more important for possible influences on climate.”

With sun's activity set to diminish, is global cooling coming?

The models have not failed, they have predicted exactly what has happened and been good at hindcasting within their range of predicted outcomes.

The planet has continued to warm under the influence of a cooling La Nina dominence and will continue to over the next 20years.
