  1. Indeed, but if you go much further back CO2 has been higher as have temperatures. So there's no doubt that life can survive but it had plenty of time to adapt as those maxima happened over millions and tens of millions of years. What's coming is (on a geological scale) going to be near instant and it's going to play havoc with life. A plant that can move its range and evolve over millennia to suit previous warm periods is not going to manage that if the predicted speed of change proves to be accurate and is decades or centuries. We need urgent action. Urgent. Burying your head in the sand will solve nothing.
  2. Yes, it has indeed been higher in the past. So life can survive and thrive at higher temperatures. Those higher temperatures took a long time to arrive (millions of years) and life had time to migrate, adapt and evolve. The important question is can life as we know it survive at those higher temperatures if we jump to them over a few decades or centuries, as seems to be likely to happen?
  3. And in other news, scientists have revealed the way they calculate how much weight bridges can take. What they do is drive heavier and heavier lorries over them until they collapse. Then they know the maximum weight and they rebuild them. Simple. Your evidence? What's the carbon footprint of a diesel engine?
  4. If you want to feel better informed about electricity generation and how much UK electricity comes from zero emission sources you could do worse than look at http://www.gridwatch.templar.co.uk/
  5. At 7 minutes he makes it crystal clear it wasn't charged there. It was presumably plugged in long enough to show on the car's screen how long a recharge would take. How does that undermine his case? Only if you're desperate for him to be wrong about the car being OK for the journey. Amazes me how people don't want this to be a technology that works. I can't understand why but this site seems to be full of people keen for things never to improve if it means change.
  6. No he didn't. Jesus. It's almost as if you don't want cars to have a genuine 250 mile range so you can bang on about how bad change is. I genuinely despair for the country when so many people apparently hate change.
  7. Here's Quentin Willson driving a Tesla model 3 on a journey from London to Stratford-upon-Avon and back on a charge. At 70-75 mph.
  8. What about it? I'm interested how that proves that when there's no wind... the existing power stations won't be able to cope with demand.
  9. I've made no claim. I'm just doubtful of yours. That's the basis of scepticism. You're the one making a claim (that "When there's no wind... the existing power stations won't be able to cope with demand). It's your job to provide the evidence.
  10. You're comparing the measured energy density of a particular graphene-based battery with the theoretical maximum of aluminium-air.
  11. Graphene power storage anyone? Not all technologies are based on current battery types.
  12. I'd love to see the evidence you have for that. Luddites of the world unite! You have nothing to lose but your diesel It'll take the EU to legislate a type approval for charging points. Which they will do but the technology is new. They'll do it soon (as the EU fights restrictive practices like this by businesses) then you'll be able to cross Europe and use any charger anywhere and it'll fit your vehicle.
  13. Genuinely interested why that's relevant to the debate? How about "How many fuel refineries will shut down when charging stations become the norm"?
  14. And the fact that only around 1% of cars are electric at the moment seems to have escaped others. That's a bold forecast. Would you have said the same about mobile phones in the 1980's when a brick-sized battery gave half an hour of talk time?
  15. It would be utter madness to fit charging points around the canal system until technology exists that can utilise it. And it's possibly not going even going to be necessary. Given the right energy storage solution I see it being run privately in the same way diesel is sold at present. If you can stop once a week for diesel you can stop once a week for energy in another form. When cars that needed unleaded fuel were coming in, people said exactly the same about unleaded fuelling stations. They'll come. There are already more than you might expect. Get up Google maps and look for ev charging stations:
