Below I am adding to the list including several newly documented mechanisms.

1. Heat stress reducing crop yields https://t.co/7SNN00rNox\xa0

2. Heat stress on farmers (sometimes fatal) https://t.co/jYKjwATe5S, https://t.co/wtcp0kT8Wk\xa0
3. Heat stress on livestock (often fatal) https://t.co/MxogLlksC2, https://t.co/RiJ0A7ezld, https://t.co/rGX2UTTUJM
Several primary impacts relate to altered soil & plant chemistry & biology:
1. Disruption of the phosphorous cycle - the second most vital element for plants after nitrogen
2. Decreased content of key nutrients in major
3. Reduced chill hours required for many plants to bloom normally in the
Other additional primary impacts include:
4. Fossil fuel pollution impacts on crops - this is not a result of climate change per se, but is included since it is due to the same root cause (fossil fuel use):
'future warming and unmitigated ozone pollution in the US, could cause a decline\xa0of 13% in wheat crops, 28% in soybean yield, and 43% in maize by 2050'

Watch along:
Just 15 mins until the launch event for our new advice to Government on the Sixth Carbon Budget. If you haven\u2019t registered, you can watch live on YouTube from 10am. Link: https://t.co/PjlcIDSYEC #UKCarbonBudget pic.twitter.com/1zOTfmxDVp

Will tweet along snippets. Pretty relevant to...............everything, really. #UKCarbonBudget
"Instead of being just a budget, it's a pathway we have to tread to reach net zero in 2050" @lorddeben
Just like quite a few other modelling exercises, CCC use a spectrum between behaviour change and between technological change. #UKCarbonBudget.
Both = best (just like @AEMO_Media's Step Change scenario in their ISP)

'Balanced' is what they use for their recs. "We're doing 60% of the emissions reductions in the first 15 years, and then 40% in the next".
The slinky kitty curve....good to see. No evidence of delaying action to Dec 29 2049, here. #UKCarbonBudget

"By front loading, we're minimising the UK's contribution to cumulative emissions" - really important point. A slow path to net zero - more climate harm than a fast one. #UKCarbonBudget
