"The real story is much, much more urgent". I'm ready to watch @dwallacewells speaking on "A story of the future of earth" at #RSAclimate. Starting urgently! thersa.org/events/2019/02…

"Thanks for giving up your lunchtime to attend this event", says @fionaharvey as she introduces #RSAclimate. "Quite how many more lunchtimes we'll have is something we might ask @dwallacewells later", she added, deadpan

Far more important than steps to minimise our personal carbon footprint (e.g taking fewer flights), if we care about preventing adverse climate change, is to vote for political leaders deeply committed to effective policy change - @dwallacewells at #RSAclimate

We could stop spending $5 trillion on subsidies to the fossil fuel industry each year, and spend $3 trillion of that fund to use presently available technology to remove greenhouse gases from the atmosphere - one encouraging message from @dwallacewells at #RSAclimate

.@dwallacewells went on to say that most of this $5 trillion could be spent on more effective (less roundabout) solutions to greenhouse gas accumulation, e.g changing practices in various industries, and accelerating next generation renewable energy systems #RSAclimate

Here's one source for that #RSAclimate @dwallacewells figure of $5 trillion annual subsidies for the fossil fuel industry. Unsurprisingly, it turns out that it's not coming out of a single pot which could be easily redeployed for other uses google.com/amp/s/amp.theg…

More energy has been consumed by Bitcoin processing than has been generated by solar panels - @dwallacewells gives a surprising example of #UnintendedConsequences at #RSAclimate

On investigation, I may have misheard something at the tail end of #RSAclimate. The highest rate of energy consumption by Bitcoin has been around 73TWh/year, according to digiconomist.net/bitcoin-energy…, whereas in 2017 alone, 443 TWh of solar energy was generated en.wikipedia.org/wiki/Solar_pow…
