Here's an estimate that shows one third of all species going extinct by 2070 https://www.cnn.com/2020/02/21/weather/species-extinction-climate-trnd/index.html https://www.cnn.com/2020/02/21/weather/species-extinction-cl... And "In a worst-case scenario, that number could rise to over 55%."
- ckastner 6y agoThis protected death of millions of species, 50 years out from now, is based on an analysis of 538 of them. That sounds woefully inadequate information for something as complex as what this model is trying predict. That's like predicting the weather from only a handful of temperature sensors, or doing patient studies with N=4.
- hanniabu 6y agoIf you select the proper species then you can make fairly accurate deductions due to cascading effects of the food chain.
- diveanon 6y agoKey indicators and foundational species like coral are effective metrics. A mass die offs of coral, which is currently happening, will decimate ocean ecosystems and have a cascading effect on the rest of the world. People have been saying this for decades, its not new news. Its just inconvenient and impacts shareholders.
- giardini 6y agoLuckily no one is able to predict most anything beyond 4 years in the future. Ask any economist or epidemiologist.
- diveanon 6y agoThis is false. We have been accurately modeling climate change for over 50 years now. Also, epidemiologist have been predicting a coronavirus outbreak specifically for about 10 years, and a larger global pandemic for about 100. You can choose to ignore science if you want, but that doesn't mean people havent been warning us.
- the-dude 6y agoSo they have been wrong for about 100 years. Great record. I predict the sun will run out of steam and we are all gonna die. Furthermore, some volcanos will erupt too. And we have not been 'accurately predicting the climate for 50 years' : about 50 years ago, there were worries about a new ice age.
