A nationwide poll conducted earlier this month by the University of Texas found American belief in climate change has increased 5% since March 2012, totaling 70%. As seen in other recent reports, the findings suggest that observations of current weather patterns are proving to be the largest explanations for shifting views on climate change. For instance, there was a 13% increase in belief amongst respondents in drought-stricken Texas.
Record Heat Wave Pushes U.S. Belief in Climate Change to 70%

A record heat wave, drought and catastrophic wildfires are accomplishing what climate scientists could not: convincing a wide swath of Americans that global temperatures are rising.
In the four months since March there has been a jump in U.S. citizens’ belief that climate change is taking place, especially among independent voters and those in southern states such as Texas, which is now in its second year of record drought, according to nationwide polls by the University of Texas.
In a poll taken July 12-16, 70 percent of respondents said they think the climate is changing, compared with 65 percent in a similar poll in March. Those saying it’s not taking place fell to 15 percent from 22 percent, according to data set to be released this week by the UT Energy Poll.
Following a winter of record snowfall in 2010, the public’s acceptance of climate change fell to a low of 52 percent, according to the National Survey of American Public Opinion on Climate Change, which was published by the Brookings Institution in Washington. After this year’s mild winter, support jumped to 65 percent, the same as that found by the UT Energy Poll in March.
“There has been a rebound in belief” in global warming, Barry Rabe, a University of Michigan professor who published the research on the Brookings study. “All respondents are quite likely to use observations of weather as a big part of their explanation.”
The average temperature for the U.S. during June was 71.2 degrees Fahrenheit (21.7 Celsius), which is 2 degrees higher than the average for the 20th century, according to the National Oceanic and Atmospheric Administration. The June temperatures made the preceding 12 months the warmest since record-keeping began in 1895, the government agency said. The U.S. is also experiencing its worst drought since 1956, with 55 percent of the contiguous states in moderate to severe drought.
Global temperatures reached a record in 2010, with data showing surface temperatures increased at a rate of about 0.31 degrees Fahrenheit since 1980, according to a NOAA report released this month. Those temperatures fell last year because of the effect of La Nina, a weather pattern associated with cooler waters in the equatorial Pacific. Still, it was one of the 15 warmest years on record, the annual State of the Climate report said.
