@Jeremy_Williams This is what mankind's CO2 emissions are doing to the planet (NASA video):

@Jeremy_Williams CO2 emissions are changing whole ecosystems:

@NatGeo : "Vast swaths of North Africa are getting noticeably lusher due to warming temperatures, new satellite images show, suggesting a possible boon for people living in the driest part of the continent."

@Jeremy_Williams @NatGeo @newscientist When I was a child, horrific famines were often in the news, in places like Bangladesh. But Bangladesh and India now have food surpluses, every year. Rising CO2 level is one of the reasons for that.

@Jeremy_Williams @NatGeo @newscientist Elevated CO2 helps warm the Earth, but there's no convincing evidence that's harmful. In fact, scientists call warm climate periods "climate optimums."

Elevated CO2 is also VERY beneficial for agriculture — a fact known to science for >100 years.

@Jeremy_Williams @NatGeo @newscientist Famine used to be a scourge comparable to war & disease.

@Jeremy_Williams @NatGeo @newscientist The scientific evidence is compelling that manmade climate change is modest and benign, and CO2 emissions are net-beneficial, rather than harmful.

Here are some relevant papers:

@Jeremy_Williams @NatGeo @newscientist The best evidence shows that manmade climate change is real, but modest & benign, and CO2 emissions are highly beneficial.

The major harms are all merely hypothetical (& mostly implausible). The benefits are real, measured & very large.
