Research reveals Earth’s core affects length of day Research at the University of Liverpool has found that variations in the length of day…

Claim: Faint Young Sun Paradox solved

From the University of Colorado at Boulder a claim that computer modeling has solved the problem, with an atmosphere that is 20,000 parts per million of  CO2 and 1,000 ppm of methane. CU study shows how early Earth kept warm enough to support life Scientists tackle faint young sun paradox with 3-D climate models Solving…
