Australian cities could soon see unprecedented temperatures of 50C, scientists say

Australian cities could soon experience “unprecedented” temperatures of 50C, even if international climate targets are met, scientists have said.

Summers in Sydney and Melbourne could regularly see sweltering temperatures by 2040, raising concerns for how the elderly will cope and the pressures the weather could pile on energy resources and infrastructure.

Restricting global warming to 1.5C – less than the 2C which was agreed by the international community under the Paris climate deal – could avoid the 50C days, scientists said.

1. And it won't stop there.

I'm not young, and I fear that even in my lifetime, huge swaths of the earth will be uninhabitable.

5. Technically they already are.

But huge swaths that are currently habitable, soon won't be.

3. 2C

Once the temp catches up to the CO2 content in the atmosphere the rise in mean temperatures across the planet are going to go well past 2C. None of the climate data taken from ice cores going back 800,000+ years shows a CO2 content anywhere close to what we are at today. The data does show a uniform tracking of Temp to CO2. The highest CO2 number seen during that time span is around 300-320ppm of CO2. Today we are over 400ppm. The temperature will catch up and it is going to get much, much warmer.
