With an annual summit next month, the United Nations assessed progress on countries’ past emissions commitments. Severe disruption would be hard to avoid on the current trajectory.
SHORT NOTES FROM NASA
Human activities, such as the burning of fossil fuels, have made Earth’s “puffy coat” warmer. But Earth’s atmosphere can’t simply take off its jacket when it gets too hot. We can, however, stop adding insulation.
There were even disbelieving replies (or comments, whatever) to NASA’s concerns. And of course as I mentioned earlier, there’s a book out denying climate change, with boocoo agreeing responses. I won’t give him the publicity by mentioning his name, but the astrophysicist maintains that “masterful analysis decisively shows that the pessimistic, and often alarming, global warming scenarios depicted in the media have no scientific basis.”
I’m so thankful I didn’t become a teacher!
MAMA EARTH VS BITCOIN
Excerpt from Greenpeace: Bitcoin’s exponential electricity usage is making the climate crisis worse…
For those who don’t know, Bitcoin is a digital currency known as cryptocurrency. Since 2009, Bitcoin has grown to become the most popular cryptocurrency there is. With that growth has come an explosion in electricity usage — all because the code that makes Bitcoin run is outdated and extremely energy-intensive by design.
13 years since its release, Bitcoin uses as much electricity as entire countries. Bitcoin’s unsustainable growth has already led to the resurrection of multiple coal plants and hundreds of thousands of tons of carbon emissions….
The good news is that Bitcoin doesn’t actually have to use so much electricity. Other less-popular cryptocurrencies are proving that by adopting a more modern coding system, Bitcoin’s energy usage can be reduced by 99%.
