Part 8 of the series that shows the evidence for our origins -- from the big bang to the human migration out of Africa.

PLEASE NOTE: My reference to "opposable thumbs" in this video is confusing and badly worded. All apes have opposable thumbs, but only in humans can the thumb swing across the palm and touch the small and ring fingers, giving us exceptional dexterity that apes don't have, and which can be seen in some hominid fossils. This is technically known as "ulnar opposition." Rather than spend time explaining this in the video, I've decided to take the words "opposable thumbs" out of the DVD being distributed for schools.

The "adult" version -- the original Made easy series -- can now be uploaded as a BitTorrent. Check my channel for details. Please download and seed!

7. Climate Change - Those e-mails and science censorship

How accurate are scientific predictions about climate?

Fact checking claims about lockdown (and Sweden)

This 4-minute video got climate skeptics very excited (and doesnt say what they think it says!)

$A clean energy solution embraced by both sides of politics The charity I endorse is called Health in Harmony (see my video https://www.youtube.com/watch?v=j9-GRugP9pU.) It funds hospitals and affordable health care to villages on the edge of a national parks, in return for a pledge not to cut down trees. The pledges are monitored, and the result has been a dramatic decrease in deforestation rates and an increase in the health of the local population. Thanks to your generous contributions so far, amounting to nearly $200,000, the founders are spreading the idea to other countries. See also https://psmag.com/social-justice/save-the-trees-well-save-your-life-46121 for an explanation of their work.

It was in the script, I simply misread it. Earlier, Elon Musk mentioned 100 MW for the Hornsdale battery. This is the output of the battery, not the storage capacity.

So, for example, I didnt forget to mention that South Australia has large unpopulated areas and a small population. Because if I had, I would then have had to mention that the amount of land taken up by wind and solar farms is just a tiny fraction of that. And I would have had to mention that sparsely populated areas often have bigger problems than densely populated ones, because grid infrastructure has to spread over a greater distance for less money. I also didnt forget to mention that South Australia is a desert state, because it isnt. Some of S.A. is desert, some is semi-arid, some gets plenty of rainfall. I also didnt forget to mention that not every country has the kind of sunshine and wind that South Australia does. If I had, then people would have told me I forgot to mention that countries that dont have a lot of sunshine often dont have a lot of wind, and vice-versa. Or that the two largest CO2 producers, China and the USA, have plenty of sunshine and wind. Or that even countries that have neither can still import energy from other countries. I didnt forget to mention that battery and lithium production creates CO2. So does power station and coal production. As more renewable energy is installed, the power needed to make these batteries will increasingly be clean, producing almost no CO2. I didnt forget to mention Scott Morrisons recent commitment to nett zero carbon by 2050. If I had mentioned it, then other posters would have told me I forgot to mention that there is no plan to go with it. And I would have been told that I forgot to mention that there is no change to the governments policy up to 2030. I didnt forget to mention that batteries can catch fire. If I had, someone would have told me I forgot to mention that oil wells also catch fire. So do coal mines. So do power stations and oil refineries. I cant write a list of everything that catches fire. One thing that has not caught fire is the Hornsdale battery. If it ever does, Im sure theyll put the fire out and rebuild it, just as they do with oil wells. I didnt forget to mention that the Business Council of Australia has also just reversed-course on renewable energy and called for a 50% reduction in carbon emissions by 2030 , after saying a few years ago that a 45% reduction would be economy wrecking. Lots of people and institutions are changing their minds, and I dont have time to mention them all. I chose News International because it was the most significant. I didnt forget to mention the fact that birds get killed by wind farms and turbines catch fire. If I had mentioned this, there would have been more posts telling me I forgot to mention that birds also get killed by oil spills. And if you think there are things I forgot to mention in this list, I havent forgotten to mention those either. I cant make this video description 6,000 words long any more than I can make the video 6 hours long. Sorry.$
