Scientists can study Earth’s climate as far back as 800,000 years by drilling core samples from deep underneath the ice sheets of Greenland and Antarctica.

Inc is exploring a technology first developed for the U. military to produce tasty prepared meals that do not need refrigeration, as it looks for new ways to muscle into the 0 billion U. The dishes would be easy to stockpile and ship because they do not require refrigeration and could be offered quite cheaply compared with take-out from a restaurant.

A public health researcher at Queen Mary University in London says that nuclear warfare could lead to environmental impacts such as fires, soot in the stratosphere, and declines in global food production.

However, other researchers soon pointed out that those measurements didn't correct for the fact that satellites slowly lose altitude as they orbit and that once these corrections are made, the satellite measurements were much more consistent with the warming trend observed at the surface.

Christy and Spencer immediately acknowledged the need for that correction.

Through the action of this community, science is self-correcting.

For example, in the 1990s, John Christy and Roy Spencer reported that temperature measurements taken by satellite, instead of from the Earth's surface, seemed to indicate that the Earth was cooling, not warming.
