Comments by "" (@DanielSMatthews) on "'Every chance' Biden wins and US goes to net zero emissions" video.

  1. The technologies required to achieve net zero emissions before 2050 simply do not exist, yet. The president of the USA doesn't matter in this regard. Only viable commercialised fusion energy reactors rolled out across the globe, will allow for a genuine net zero emissions and the rate of that technology development is limited by the number of human minds that are skilled enough in the requisite knowledge, and that comes down to genetically determined intelligence levels. Furthermore that economist is clueless, steel is up to 2.1% carbon by weight and without it you just have iron which has very different physical properties. You would need to also switch to titanium in building and engineering to have a carbon free process, which is not a bad idea but the costs without massive amounts of cheap electrical energy are prohibitive. 2050 is an aspiration and anyone who claims that they have the power to make it happen faster than it will happen anyway is a deluded megalomaniac.

  2. Probably kill millions of people too as a lot of that carbon based energy goes into the inputs for the farming sector and global food transport to even out the impact of natural weather variations across the globe which impact on local productivity.
