Two new studies suggest that a hotter world would result in less and thinner cloud cover (Study 1) that traps more heat than previously thought (Study 2, video above). This has led the researchers to conclude that climate may be much more sensitive than current, already catastrophic, but apparently deficient, worst-case scenario temperature projections indicate.
One thing we at ecoSanity have found to be true about climate science: Most estimates are soon revealed to be (often considerable) underestimates.
Why does it matter?
At present, the world's atmosphere is on an accelerating course to reach a state of potentially unsurvivable, runaway global heating and climate breakdown extremes DURING THE LIVES OF TODAY'S CHILDREN and only EMERGENCY international action at EMERGENCY (world-war time) speed *may be* proportional enough to confront the scale, scope and urgency of this unprecedented threat.
