Just checking the title of the thread.... We need one 'Argument Clinic' maybe? "I'm sorry, is this the 5 minute argument or the full half hour"
Climate change... regardless of your belief into climate change and the causes I think we all accept that it is changing... even Trump seams to accept that, accusing windmills of causing cancer rather than trying to debunk climate changes.
If you are considering areas drying out, the Sahara desert has got about 10% bigger since 1920.... which also kind of coincides with the exponential increase in world CO2 levels at that time... global warming? and well before the Aral sea. No one knows quite all the causes... and I think it is one system and each change will change everything also... divert water to cotton fields, sea empties, has an effect, CO2 levels rise from human activity, has an effect, but the world wide scientific consensus is CO2 is more to blame than anything (other gasses are more potent - cow farts - but there is less of them).
I am happy to throw my hat into that idea... yes sea has an effect, but CO2 more of an effect.
Going back up a step though, renewable energy - adding it here since it is all tied together (Trump bashing later if I get bored). The world has enough oil for 30 to 35 years (at the current rate of use) plus some that is not economic to extract just now (Wikkipedia)... it will run out but in that time Africa will want to electrify itself, come onto the WWW, rural China will want the same, Rural India... and all increasing demand.. oil is going to run out, coal is going to run out, we can cut down the Amazon for wood chip or we can become world leaders of extracting energy from outside the plant (ie the sun).... wind and solar mainly, maybe tidal or wave plus perhaps stored hydro, small nuclear reactors but the days of oil and gas is limited... and now is the time to change before everyone is and demand exceeds supply.. and then your poor granny will be freezing!
Second comment is a repeat of one I made before, the UK is at the mercy of the worlds 'stable' nations for oil supplies - Russia, North Africa / Middle East, Central Africa potentially... not sure I want to be held hostage by any of them over my electricity prices. Well known for their current mentally stable leaders. Back to Trump anyone?
Yes back to the topic, I'd be more inclined to believe that Harris is more sympathetic than Trump-in-the-Texas-Oil-Barons-Pocket to renewable energy, and has a more global outlook on the world that perhaps they can also become world leaders in renewable energy rather than following the Chinese (who incidentally also installed the most renewable energy last year). Be happier buying European or US windmills than Chinese ones... but that means we need to take a lead and do it ahead of everyone else
