Read here. Map source. A major claim of climate alarmist scientists is that global warming will endanger or kill off species. Almost all these claims are made based on computer simulations/models, with no empirical evidence foundation. Fortunately for humanity, real scientists continue to do research that documents that climate warming is actually very good for almost all species.
In a peer-reviewed study by Nakamura et al., empirical evidence was gathered from a unique experiment that proved oak trees responded very favorably to warmer temperatures. And as a result, one could surmise that squirrels will be very fat and happy in the future of global warming.
"Working in Japan's Tomakomai Experimental Forest, the authors employed a construction crane to lift themselves some 18 to 20 meters above the ground, where they attached, via adhesive tape, 120-meter-long electric heating cables to some of the top canopy branches of three tall, mature Quercus crispula oak trees, by which means they continuously warmed their developing shoots approximately 5°C above local ambient temperature for the next full year.....five researchers report that time of leaf flush in the spring was unaffected by warming; but they found that the growing season of canopy leaves was extended by later leaf fall.....And, perhaps most impressive of all, they discovered that "when acorns were present, warmed branches had about double the number of acorns found on control branches."
