Predict your climate averages for 100 years into the future (snow, warming, Chicago)

Using the same method (I was going to do the same but take the 1971-2000 and multiply the difference by 10 ).

°C
3,1 / 11,2
1,5 / 9,9
5,4 / 17,9

15,8 / 31,6
12,4 / 22,7
10,9 / 18,3
7,0 / 14,0

44,6 / 57,2
34,3 / 49,3



Hmm okay.

Here highs warmed up faster than lows in the last 20 years.

I think in my area months from December to March will have an average temperatures 1,5 c higher than now, months from June to August 1 c (or a bit less) higher averages than now, the rest of months will have the same average temps.
Amount of precipitation will be annually ca 20 % bigger than now, there will be less annual sunshine hours than now and there will be more days with thunderstorms than now.

Current averages for Hong Kong:

Jan 18.6 / 14.5
Feb 18.9 / 15.0
Mar 21.4 / 17.2
Apr 25.0 / 20.8
May 28.4 / 24.1

Sep 30.1 / 25.8
Oct 27.8 / 23.7
Nov 24.1 / 19.8

2081-2110 normals prediction:

Jan 22.1 / 19.9
Feb 22.3 / 20.3
Mar 24.7 / 22.4
Apr 28.2 / 25.9
May 32.5 / 29.1

Sep 33.2 / 30.8
Oct 31.0 / 28.8
Nov 27.4 / 25.0
Dec 23.6 / 21.4

It'll become far more 'tropical', with warm winters and very hot summers.

Our temperatures will probably stay roughly the same with a bump in lows and highs by a degree or two F, but the big change will be rainfall totals which may drop significantly wreaking havoc on the redwood ecosystem. Less fog is already affecting the health of the redwood forests and the problem may only get worse as time passes and the climate warms. Conversely, we may actually get MORE fog as inland areas heat more which could make up a bit for less rainfall, but one can never really tell and I'll be long dead before the effects are really starting to be felt.

For Malta, if they continue to increase at the same amount as from 1951-2010...

Might be something like this:



Bye bye, snow.

that's just horrible. i don't even want to imagine what gothenburg would look like in a scenario like that.

[brownbagg]

i say about a half degree colder

Interesting, in your case it seems January warmed up more than February (just like in Nice), leading to this quirk. Your summer increase looks over the top, like mine. 32°C average high? I doubt it.

Autumn looks realistic in your scenario. 12/23 in September and 11/18 in October are in no way excessive for Paris. That September low (12.4°C) is even lower than Montsouris' 1981-2010 value.

My forecast for central Paris, 2081-2110:

°C

Feb 5/10

Apr 10/17

Jun 16/23

Sep 15/23
Oct 12/18
Nov 8/12
Dec 6/10

The further inland and east you go, the more April-June will lead August-October.

Lappeenranta retains some possibility for snowy winters:
