New research increases concerns about sea-level rise along the Texas coast

Texas officials don't like to discuss the role of human activities in causing seas to rise. But as research findings continue to accumulate, like a new study on the melting of Antarctic ice, science is filling their silence.

Gulf fish populations among those shifting in response to climate change

Fish are sensitive to water temperature and, as climate change warms ocean waters, their distribution is changing. A recent study projects some species off U.S. coasts shifting northward to more suitable temperature ranges.

Texas is a ‘hot zone’ for diseases borne by mosquitoes, ticks and fleas

Nationally, disease cases caused by these creatures tripled from 2004-16, a recent federal study found. With global temperatures rising, Texas is “at the epicenter of vector-borne diseases,” says a Houston expert.

Walkable cities are friendlier – but what if climate change makes it too hot to walk?

Just a few extra degrees can turn a healthy walk harmful. Human-scale urban design will have to protect walkers from rising temperatures. Texas A&M researchers aimed to quantify how much vegetation is needed.

Scientists continue hunt for causes of die-off at marine sanctuary in Gulf

Members of many species perished at the Flower Garden Banks in the “highly localized mortality event” in 2016. The protected area's coral reefs are relatively healthy, but coral is stressed by climate change worldwide.
