Is our climate cooling down or warming up? A new study of past climate data reveals that, despite previous belief, there has been a consistent global warming trend over the last 10,000 years, rather than a period of global cooling before humans intervened.
"We have been building models and there are now robust contradictions," lead study author Zhengyu Liu, of the University of Wisconsin-Madison, said in a news release. "Data from observation says global cooling. The physical model says it has to be warming."
Our current geological epoch is called the Holocene, and the problem Liu is describing is referred to as the Holocene temperature conundrum.
Determining the cause of these clashing findings has important implications for understanding climate change and evaluating climate models, as well as for the benchmarks used to create climate models for the future. However, the researchers stress that their recent study does not change the evidence of human impact on global climate beginning in the 20th century.
"The question is, 'Who is right?'" Liu said. "Or, maybe none of us is completely right. It could be partly a data problem, since some of the data in last year's study contradicts itself. It could partly be a model problem because of some missing physical mechanisms."

Generally, it is best to go with the lie that is supported by the latest weather situation. For a hurricane it should be global warming. For a snowstorm it should be global cooling. It can get tricky sometimes when it it snowing up North and a hurricane hits at the same time which requires segmentation of the global warming or cooling claims by area to ensure there is not conflict.
There was a big ice age. Covered part of the USA and Europe. Went away by itself. No human help.
The climate is always changing. There are warming trends followed by cooling trends. They are beyond human control. Get used to it.
How about they shut up and give their funding to fighting cancer?
