Deserts cool the planet by reflecting solar radiation to space; vegetated areas have an overall warming effect, so planting trees in deserts doesn’t necessarily cool the planet
Claim:
"Deserts are heat producers, reflecting around 60% to 70% of the solar energy that falls on them straight back into the atmosphere."; "If we want to do something about global warming, we have to do something about deserts."
Analysis of "What we’re doing to the Earth has no parallel in 66 million years, scientists say"
“It sadly implies that even the PETM, a massive warm climatic excursion, might not be harsh enough to represent an analogue for future climate change, as the Washington Post rightfully points out.”
Analysis of "Scientists say human greenhouse gas emissions have canceled the next ice age"
“The article presents an accurate account of recently published research which suggests that human-induced global warming will delay the onset of the next ice age by 50,000 years. The research supports the findings of several studies published over the past 15 years, and is consistent with the scientific consensus that human activity is changing the climate with very long-term consequences.”
