[font size=4]20th-century warming, researchers say, "reversed" the trend[/font]

April 21, 2013

[font size=3]The most comprehensive evaluation of temperature change on Earth’s continents over the past 1,000 to 2,000 years indicates that a long-term cooling trend--caused by factors including fluctuations in the amount and distribution of heat from the sun, and increases in volcanic activity--ended late in the 19th century.

The study also finds that the 20th century ranks as the warmest or nearly the warmest century on all of the continents, except Antarctica. Africa had insufficient data to be included in the analysis.

Global warming that has occurred since the end of the 19th century reversed a persistent long-term global cooling trend, say the researchers.

"Global warming that has occurred since the end of the 19th century reversed a persistent long-term global cooling trend," the researchers write in the report.

1. "2,000 years of climate records"?

Were those early records written on papyrus?

2. Tree rings, ice cores, sediment records, fossil evidence, etc

Really, this is all pretty common knowledge for anyone with even a basic understanding of climate science.

3. I was mocking the writing used in the headline.

4. Ooops, my bad

We get a lot of trolls around here. Sorry about that
