Climate Update - what must happen & news links

The Limits of Clean Energy
If the world isn’t careful, renewable energy could become as destructive as fossil fuels.


People must use less transport, eat less red meat and buy fewer clothes if the UK is to virtually halt greenhouse gas emissions by 2050, the government's chief environment scientist has warned.

urgent changes needed include ending population growth, leaving fossil fuels in the ground, halting forest destruction and slashing meat eating.

Global emissions need to be halved by next decade and net-zero by mid century, says energy economist Nebojsa Nakicenovic

“Nearly two-thirds of the pledges under the Paris climate agreement are ‘totally insufficient’ to meet critical climate targets.” And almost no nation in the world is on track to meet those targets.

India, the U.S. and China saw some of the biggest rises in greenhouse gas emissions in 2018, a new report says. The EU’s output fell by 2.5%

Updates for October

Temperature world wide

We just had the warmest October on record (narrowly ahead of Oct 2015), according to #Copernicus #C3S. Monthly temperatures over the past 12 months have averaged close to 1.2°C above the pre-industrial level defined by IPCC.

Bank of England boss says global finance is funding 4C temperature rise

Ocean acidification

tweet here:

“If 0.25 was enough to precipitate a mass extinction, we should be worried.”

Researchers estimate that the pH of the ocean will drop by 0.4 pH units by 2100 if carbon emissions are not stopped, or by 0.15 units if global temperature rise is limited to 2C.
