Does climate change play into the local weather equation?
At a basic level, yes, Nielsen-Gammon said.
Temperatures in Texas have increased by 1 or 2 degrees Fahrenheit over the past 30 to 40 years, he said.
“So the current record warmth is probably a couple of degrees warmer than it would have been without climate change,” he said.
Climate change, though, is not just about global warming, Hayhoe said via telephone Tuesday.
“An increase of a few degrees in our average temperature is not really going to have that big of an effect on any of us,” she said. “What’s going to affect us is that our conditions are getting more unpredictable.”
Long-term, temperatures in Texas have not warmed. Over the last ten years, temperatures have been on a downwards trend. The hottest year was 90 years ago. Year to date, 2011 is the 19th warmest – hardly “record warmth.”
