Texas Congressman Denies Climate Change While Texans Seek More Action On Global Warming

Last week, San Antonio Congressman Lamar Smith took a break from Washington’s budget battles to weigh in on the latest assessment report from the Intergovernmental Panel on Climate Change (IPCC). In his Texas Weekly guest column, Congressman Smith cast doubt on the link between global warming and extreme weather and criticized efforts to curb greenhouse gas emissions (GHGs), cherry-picking passages of the report to support his own arguments.

Let’s look at what the report really says. Based on mountains of evidence and an unprecedented scientific consensus from hundreds of the world’s best climate scientists, the IPCC finds that “warming of the climate system is unequivocal,” and “human influence on the climate system is clear.” Furthermore, the report settles that human influence has very likely affected frequency and intensity of daily temperature extremes and likely doubled the probability of heat waves. The report further predicts that extreme heat will only get worse from here, concluding it is very likely that heat waves will occur with a higher frequency and duration in the future. Sounds like extreme weather to me.

When you contrast these findings with Texas’ recent streak of scorching summers, it’s easy to understand why a majority of Texans say they have personally experienced the effects of global warming. Extreme temperatures, since 2010, have helped plunge the state into a historic, multi-year drought, which is expected to be the new norm. Both the National Oceanic and Atmospheric Administration (NOAA) and independent climate scientists, including Texas A&M’s atmospheric sciences department, have attributed Texas’ historic 2011 heat wave and drought primarily to climate change.

Texans Believe In Climate Change—It’s Time Our Voices Are Heard

Last month, the Intergovernmental Panel on Climate Change (IPCC) released its fifth report on where humanity stands on climate change. IPCC brings together thousands of volunteer scientists and other global experts to review humankind’s current scientific understanding of climate change. After these academic experts have come to consensus, officials from nearly 200 U.N. member countries review their results. The latest report shows that we are more certain than ever before that the climate is changing, and if humanity doesn’t act now, we could face devastating warming in the future.

The broad international consensus on climate change stands in stark contrast with what we typically hear from our elected representatives in Texas. Too often, they call climate change “unsettled science,” or claim that some uncertainty around the extent of warming warrants inaction from the state that emits the most carbon dioxide in the nation. The state’s environmental agency, the Texas Commission on Environmental Quality (TCEQ), famously censors mentions of climate change from its reports. And even more aggressively, the state has fought the Environmental Protection Agency’s (EPA) permitting process for large sources of greenhouse gas emissions (GHGs) tooth and nail. Read More »
