Delayed slow ocean response to carbon dioxide removal causes asymmetric tropical rainfall change
Using fossil fuels causes large amounts of carbon dioxide (CO2) to be emitted, which is one of the major greenhouse gases responsible for global warming. The climate changes under increasing CO2 radiative forcing (called "CO2 ramp-up") have been widely projected using numerical experiments. For a carbon-neutral world, more studies have begun to focus on the regional climate responses under...
What caused the holes in SUE the T. rex's jaw? Probably not an infection
SUE the T. rex is one of the most complete, best-preserved Tyrannosaurus rex specimens ever found. That level of preservation helps reveal details about SUE's life. For instance, SUE lived to a ripe old age of about thirty-three, and in those years, suffered their fair share of injuries. SUE's most mysterious ailment might be the holes in their jawbone.
