#IPCC's 2022 #ClimateReport shows heatwaves in Europe will become more frequent, more intense & will last longer.

By 2050, about half of the European population may be exposed to high or very high risk of heat stress during summer.

Part of the reason this sort of baffles people is that we still don't widely understand just how intensely silly it is to get energy from old dead compressed plants

Made this a few years ago but it's the same today: ~2/3rds of climate impacts relate to energy that was never 'used'

a chart showing most emissions relate to energy that was never really used, because it was emitted as wasted heat

Earlier this year, Chen et al. @science.org showed that droughts are intensifying globally, with warming. www.science.org/doi/full/10.1126/science.ado4245,
Now, Gebrechorkos et al. @nature.com confirms the same findings. Very important work, but not wholly novel doi.org/10.1038/s415...

"These techniques are all however considered more expensive or energy-intensive than cutting emissions in the first place by burning fewer fossil fuels"

I do not understand how credits from complex forms of CO2 removal like enhanced rock weathering are priced (averages at $352 per tonne of CO2 here) when scientists are still in the process of figuring out MRV. No idea about actual sequestration but let's price and trade it

Cropping season over in Zimbabwe 🇿🇼 ! After cowpea a few weeks ago, maize 🌽 has now been harvested at our rainfall exclusion site at the University of Zimbabwe @cirad.bsky.social. Yields will for sure be much higher than during the once-in-century El Nino drought last year.

Great work by PPS colleagues: Intensifying legumes with phosphorus fertiliser and inoculants in smallholder fields increases yields and reduces weed pressure, enabling greater resilience to weeding delays and more flexible farm management

Low yielding and low data in smallholder farming systems is not a question of fate.

Because it is less easily derailed by quoting one dissenting opinion.

Seems like a good idea!

Could drought and poor soil undermine the performance of intercropping ?

Our study in semi-arid Zimbabwe found that the benefits of intercropping are maintained even with water and N stress.
