Study: Effects of manmade climate change will be felt for 10,000 years

EXCERPT: At the rate that humans are stuffing carbon into the atmosphere, the planet may suffer irreversible damage that could be felt tens of thousands of years, a new study has warned. Discussions on climate should go beyond what happened in the past 150 years and their impact on the world’s warming and the resulting sea level rise by this century’s end – and instead consider the longer-term effects, urged the authors. Paleoclimatologist and study lead author Peter Clark warned that the effects of climate change on Earth will be felt for thousands of generations....
Prolonged southwest drought could kill all trees in region by 2100

EXCERPT: The American Southwest has started its predicted shift into a drier climate. A recent study concluded that nearly all needleleaf evergreen trees in the region will die by 2100 because of the combined effects of prolonged drought and climate change. The prediction covers the forests of Utah, Arizona, Colorado and New Mexico. The research team from the University of Delaware utilized various scenarios and models in the study, including the carbon emission limits set during the Paris climate change conference in late 2015....

There has been mention that the oceans could eventually boil off because of a runaway greenhouse effect. There is thought that earth will become a bit like venus. It is extremely unlikely that the oceans would ever boil off here by humans starting a positive (self-increasing) feedback loop from burning fossil fuels because there has never been a time since the earth had its full oceans when they boiled off from any cause. Those oceans probably never at any time reached an average temperature anywhere near the boiling point, not even after asteroid impacts which can send a heated shock wave around the globe.

The earth has oscillated back and forth from so many extremes over its billions of years history that I doubt it as well. The oceans got so hot during the era of the Siberian Traps that they were part of the mass extinction event circa 250 million years ago. The cold cycle experienced its maximum possibility with the snowball earth eras. The outbreaks of massive volcanic activity which brought an end to those must have been gigantic in their own right, in terms of releasing the necessary greenhouse gases to melt that planetary ice-cube. Since the later Permian-Triassic extinction had the extra help of anaerobic methanogens pouring unholy amounts of methane into the atmosphere.
