Places becoming more livable
« on: July 06, 2017, 10:23:00 PM »
Article about very interesting redistribution of humidity due to global warming. From dry to wet: Rainfall might abruptly increase in Africa’s Sahel . It's a region that historically has been more humid, and 'green' than todays very arid/desert.

"Climate change could turn one of Africa's driest regions into a very wet one by suddenly switching on a Monsoon circulation. For the first time, scientists find evidence in computer simulations for a possible abrupt change to heavy seasonal rainfall in the Sahel, a region that so far has been characterized by extreme dryness. They detect a self-amplifying mechanism which might kick-in beyond 1.5-2 degrees Celsius of global warming."

Maybe you wanted to put that in the less liveable thread?

Well, Siberia will get more livable:

Only while the Arctic holds and after the NH hemisphere stabilizes after an Arctic collapse ( decades?). In the time in between collapse and climate stabilization Siberia will be uninhabitable.

Global heating: London to have climate similar to Barcelona by 2050
"London will have a similar climate in three decades’ time to that of Barcelona today, according to research – but if that seems enticing, a warning: the change could be accompanied by severe drought."
Severe drought in London?!

OTOH, more places will become less livable: Nearly 80% of cities to undergo dramatic and potentially disastrous changes, study finds. "Among the most concerning findings is that the residents of about a fifth of cities globally – including Jakarta, Singapore, Yangon and Kuala Lumpur – will experience conditions currently not seen in any major cities in the world."

I believe the Waterloo Region in Ontario's "livability" has increased over my lifetime.


Improvements:
The river no longer freezes over each year so the Spring Floods, once the fear of everyone up and down the river no longer occur.
The river no longer suffers from pollution and won an international competition for the remediation.
The roadways suffer far less from flooding and frost heaves.
Universities have replaced factories and mills as the major regional employers.
Education has improved;
Healthcare has improved in quality and availability since it was nationalized.
Spring, Summer and Fall have extended. Winters are shorter and warmer.
The available social safety-nets have improved.
Median income & wealth have improved.


Neutral:
Skating has moved indoors.
Swimming is replacing skiing and snowshoeing.
Violent crime is still very much a rarity.
Infrastructure has kept up - Mills became townhouses or restaurants. Factories were bulldozed and replaced with medium rise apartments.
The cops are and were friendly & helpful.


Worse:
Tornados have moved northward and are now seen as threatening.
AC is required in the summer.
Watering lawns in "droughts" is sometimes needed.
Fewer songbirds.
Fewer butterflies, insects.

In all this region has so far weathered global warming well.
I'd say that life here presently is better than it was before the weather began changing.

This research is complete BS. They took the maximum summer temperatures and compared those to current ones hence London to become Barcelona. They did not compare the entire climate, average temps. etc.

Besides, our climate models falsely model, and cannot replicate even the Green Sahara (cca 10k-k yr ago) or the Holocene Optimum (7k yr ago). So I have very serious doubts about the models which do not seem to get changes in atmospheric circulation right. Anyway, FWIW the European Environmental Agency has projections for 2071-2100. They see +3-4C for London with RCP8.5 by 2071-2100. Pretty far from Barcelona.

Anyway: more on topic

Central Europe has seen about 1,5-2 C temp rises since the 1950-80 period, with longer (cca 2 weeks) spring, a much warmer November, less extreme winter lows. Somuchso, that in my country figs are now not exotic anymore (they used to be), and people started to grow kiwi and oriental persimmon (I also have figs and they grow pretty well). There has been a slight increase in rains since the 80s. Summers have warmed the most, making the country more Mediterranean

It's good to see that in the Netherland we have a relative low temperature change in those scenario's;

At least we drown in 'normal' conditions...

Better than boil.... although A/C s will become more prevalent up north that they used to be
