CityCyclingEdinburgh was launched on the 27th of October 2009 as "an experiment".
IT’S TRUE!

Well done to ALL posters
It soon became useful and entertaining. There are regular posters, people who add useful info occasionally and plenty more who drop by to watch. That's fine. If you want to add news/comments it's easy to register and become a member.
RULES No personal insults. No swearing.

“On climate, the hour for collective action has already arrived. The science is here. What we need now is courage – courage scaled to the enormity of the task – so we may gift the next generation not only carbon capture, but a planet worthy of their hopes,” he said.

Can anyone understand/explain the science here?

I've only spent less than 5 minutes reading about this, but the gist seems to be that the new materials are particularly effective dehumidifiers because they can be made with a very high porosity/surface area.
A dehumidifier works by pulling air through a cooled material. Water in the air then condenses onto the surface of the material, and can then be collected as a liquid. If you have a material with a higher surface area for a given volume (think of a sponge - lots of internal surface area compared to a solid block of the same size), then you will be able to collect more water, more quickly.
I don't know what it is about the new chemistry that allows the particularly high surface area materials.
Thanks
My initial thoughts are - ‘whatever it is, you’ll need a lot, so won’t be cheap’(?)

Many of the same cost increases apply to bananas. Anna Pierides from the Fairtrade Foundation says costs for producers have been going up, and they have faced pressures from the climate crisis. There have been floods in Peru and droughts in the Dominican Republic, countries that produce the most bananas. She says it’s “not a pretty picture in banana production globally” and 30% of farmers in the Dominican Republic have left the sector.
Smith says bananas are “undervalued, underpriced” and that, in the UK, where they are now about £1 a kilo typically, if they were priced to make sure everyone in the production chain got what they should, they would be £1.50. Fairtrade has helped tens of thousands of workers to get a living wage, but producers and workers outside that system are still losing out as the price we pay is not enough.
