A group of scientists known for their skepticism about climate change has concluded that there is valid evidence that the Earth is getting warmer, Michael Marshall reports at NewScientist.
After reanalyzing two centuries’ worth of global temperature records, the scientists concluded that their questions about the accuracy of the data “do not significantly change the answer,” said lead author Richard Muller of the University of California, Berkeley.
However, critics say the real issue is not whether the Earth is warming, but whether the change is the result of human activity. “They’re concentrating on the wrong question,” said David Whitehouse, science adviser to The Global Warming Policy Foundation in London.
