The thermometers got it right. The Earth is warming, another study is reporting.

Climate scientists recognize that changes in weather observation stations' immediate surroundings -- such as neighboring trees being replaced by heat-absorbing concrete -- can eventually throw data from such stations into question.

But now, a new study directed by a researcher at the National Oceanic and Atmospheric Administration that recreates climate history without the use of land-based observation systems shows the same thing that thermometers have been reporting.

"This shows that global warming over land is real," said Gilbert Compo, a scientist at NOAA's Cooperative Institute for Research in Environmental Sciences at the University of Colorado.

In his pathbreaking 2001 book Resource Wars, Michael Klare wrote: “Natural resources are the building blocks of civilization and an essential requirement of daily existence.  The inhabitants of planet Earth have been blessed with a vast supply of most basic materials.  But we are placing increased pressure on those supplies, and in some cases we face, in our lifetimes, or those of our children, the prospect of severe resource depletion.”

Global warming has propelled Earth's climate from one of its coldest decades since the last ice age to one of its hottest -- in just one century.

A heat spike like this has never happened before, at least not in the last 11,300 years, said climatologist Shaun Marcott, who worked on a new study on global temperatures going back that far.

"If any period in time had a sustained temperature change similar to what we have today, we would have certainly seen that in our record," he said.
