Summary:  Much of the world is slowly improving.  Except for India.

The BBC showed a graphic which should be alarming to most.  These are the expected temperature increases for those cities from now (article written in 2019) to 2050:

You need to multiply by 1.8 to convert to Fahrenheit degrees.  Thus, in 2050 Seattle will be 11 F higher in the month of August.  However, the average high today is only 75 F, so 86 F might still be tolerable with air conditioning.  While Phoenix today ranges from a low or 81 F to a high of 105 F in August, the increase won't be as high as 11 F, but still, a lot worse than today, which is already oppressive.  And it's worse in July in Las Vegas.  Their all time high of 113 will surely be exceeded.  Another way to look at this is how Dallas-Fort Worth will suffer into the future.

Mecca, Saudi Arabia already has the highest average annual city temperature of 33 C, or 91 F.  Bangkok averages 35 C (95 F) from March to May with humidity in the 90's.  I've been there many times, and frankly don't remember being uncomfortable.  But I pretty much stayed in air conditioned comfort.  

Death Valley averages 117 F in the summer.  At one time there was contention as to whether the 1913 temperature there of 56.7 F or in Libya that same year was the highest.  They have both been decertified, so Furnace Creek in Death Valley's 55.4 C (129.9 F), taken on 16 August 2020, is now the official all time high for the world.   I too have visited that site, and the temperature was not quite that, but certainly intolerable.

1913 was not a particularly warm year:

The ten warmest years were all from 2005, at #10.  The three hottest were #1 2016, #2 2020 and #3 2019.

Some final data:

• The current estimate is that the planet will warm by 2 C (3.6 F) by 2050.
• Current discussions are about having the world pledging to limit rising by 1.5 C (2.7 F) by 2050.
• Current commitments are not sufficient to prevent a 2 C rise by 2050.
• Further, Planet Earth would then further increase in temperature from 2.9 C (5.2 F)  to 3.4 C (6.1 F) by 2100.
• To keep below an increase of 1.5 C, carbon emissions need to be cut 45% by 2030, and reach net zero by 2050.

You can begin by what you eat.  Perhaps I am a glutton.

More important than just showing temperature is the effect this will have on Humanity.  But that will come in a future posting.  Just one more though, sea level rise:

The New York Times has a link where you type in your city, then the year you were born.  You then can see how much the temperature has increased since your birth.  Click on that now, for they could cut-off this service in the future.  Their data only goes to 1960, but that is far back enough to compare with 2020.
