CO2 makes the planet greener.
Plant transpiration is vital to plant growth and terrestrial ecosystems.
The rising CO2 trend over the last 30 years (1990-2020) has been the primary driver of planetary greening, or increases in Leaf Area Index (LAI).
The greening, in turn, is predominantly responsible for the widespread increase in plant transpiration over this period.
These elevated trends in greening and plant transpiration are expected to continue unabated to 2100, accelerating with the increases in emissions.
“The trend attribution analysis results show that the change in leaf area index (LAI) can explain 66.2% of the global PT trend, indicating that elevated LAI due to global greening is the dominant factor contributing to the upward trend in global PT. The elevated LAI can be largely attributed to the CO2 fertilization effect induced by elevated atmospheric CO2 concentration.”
That's a lot of science-speak for "rising CO2 levels result in increased plant growth."
Increased plant growth means plants, which are, in effect, carbon sinks, increase their takeup of CO2 and their output of O2 — oxygen. That's good for plants, good for animals, and good for the planet — all without wrecking our economy with drastic carbon-emissions measures.
Who are we to determine what the Earth’s “correct” temperature range is? This little blue-green sphere is a tad over four and a half billion years old. Through most of that time, it’s been a lot warmer than it is now. As recently as the Eocene, maybe the Oligocene, there were no polar ice caps. In the more recent interglacials, global temps were higher than now. During the Roman occupation of Britain, there were vineyards that would not survive today’s British climate.
