Climate change in Texas facts for kids

Kids Encyclopedia Facts

The climate in Texas is changing due to global warming and rising trends in greenhouse gas emissions. As of 2016, most area of Texas had already warmed by 1.5 degrees Fahrenheit since the previous century because of global warming. Texas is expected to experience a wide range of environmental impacts from climate change, including rising sea levels, more frequent extreme weather events, and increasing pressure on water resources.

Texas was ranked second by GDP across the U.S. in 2020 and had a fast growing economy. According to U.S. Energy Information Administration, a large portion of Texas economic growth from 2005 to 2016 came from conventional energy production. Although Texas has a long history of conventional energy production (e.g., petroleum and natural gas), the renewable energy industry has also been rapidly growing in Texas. Solar industry jobs have been increasing and wind farms have been built in West Texas in recent years. Considering the advantages such as sunny weather, flat land and friendly business climate, Texas has high potential to develop more renewable energy in the future. In addition, there are emerging local and regional actions to address climate change across Texas. For example, Austin, Houston, Dallas, and San Antonio initiated Climate Action Plans in recent years. The government agencies also implemented programs such as Texas Emissions Reduction Plan and Innovative Energy Demonstration Program to promote the use of renewable energy and climate education in Texas.

Climate change impacts

Higher temperatures and increased frequency of heat waves may increase the number of heat-related deaths and the incidence of heat-related illnesses.

In Dallas, one study projects that by 2050 heat-related deaths during a typical summer could triple, from about 35 heat-related deaths per summer to over 100 (although increased air conditioning used during these periods may not have been accounted for). Winter-related deaths are expected to change very little. The elderly, particularly those living alone, are at greatest risk.

Air pollution also is made worse by increases in natural hydrocarbon emissions during warm and hot weather. If a warmed climate causes increased use of air conditioners, air pollutant emissions from power plants also will increase.


The Texas coastline is over 1,400 miles (2,300 km) long. The coastline is composed of wind tidal flats, sandy marshes, salt marshes, and beaches. The Laguna Madre has over 350 square miles (910 km2) of wind tidal flats that provide nesting areas or rookeries for sea birds.

The sandy marsh shoreline provides critical habitat for shorebirds, wading birds, brown pelicans, and other birds.

About 75% of the ducks and geese found in the United States move through the Texas coastal wetlands. The salt marshes provide a home for oysters and clams, and serve as nursery grounds for young shrimp, crab, and fish. These marshes protect the shorelines from erosion and also act as a purification system by filtering out many pollutants added to the waters by human activities.

At Galveston, sea level is already rising by 25 inches (640 mm) per century, and it is likely to rise another 38 inches (970 mm) by 2100. Brown shrimp catch in the U.S. Gulf Coast could fall 25% with only a 10-inch (250 mm) rise in sea level. Possible responses to sea level rise include building walls to hold back the sea, allowing the sea to advance and adapting to it, and raising the land. Each of these responses will be costly, either in out-of-pocket costs or in lost land and structures. For example, the cumulative cost of sand replenishment to protect the coast of Texas from a 20-inch (510 mm) sea level rise by 2100 is estimated at $4.2-$12.8 billion

Water resources

Several major river basins lie in part, or entirely, within Texas. Unless increased temperatures are coupled with a strong increase in rainfall, water could become more scarce. A warmer and drier climate would lead to greater evaporation, as much as a 35% decrease in streamflow, and less water for recharging groundwater aquifers. Increased rainfall could mitigate these effects, but also could contribute to localized flooding. Additionally, climate change could give rise to more frequent and intense rainfall, resulting in flash flooding.


In Texas, agriculture is a $12.6 billion annual industry, two-thirds of which comes from livestock, especially cattle. About 25% of the crop acreage is irrigated. The major crops in the state are cotton, wheat, and sorghum. Climate change could reduce cotton and sorghum yields by 2-15% and wheat yields by 43-68%, leading to changes in acres farmed and production. For example, cotton yields could fall while production rises because of an increase in cotton acres farmed. Irrigated acreage could decline slightly because of decreased water availability.

With changes in climate, the extent and density of forested areas in east Texas could change little or decline by 50-70%. Hotter, drier weather could increase wildfires and the susceptibility of pine forests to pine bark beetles and other pests, which would reduce forests and expand grasslands and arid shrublands. With increased rainfall, however, these effects could be less severe. In some areas, the types of trees dominating Texas forests would change; for example, longleaf and slash pine densities could increase in the deciduous forests of east Texas.


The vast area within Texas includes a great diversity of ecosystems, from forests to grasslands to semiarid shrublands to extensive coastal and inland wetlands. In Texas, climate change could weaken and stress trees, making them more susceptible to pine bark beetle outbreaks. Semi-arid grasslands and shrublands are very sensitive to changes in rainfall season and in the amount of rainfall, and could be affected adversely by warmer, drier conditions.

The Balcones Canyonlands National Wildlife Refuge in central Texas provides nesting grounds for the golden-cheeked warbler and the black-capped vireo, two endangered songbirds. Warmer and drier conditions could reduce critical habitat in the refuge and further stress sensitive plant and animal populations. The coastal wetlands, which support important fisheries and provide vital wildlife habitat, are also vulnerable to climate change. For example, Brazoria National Wildlife Refuge, a 43,388-acre (175.59 km2) coastal estuarine and coastal prairie habitat on the Gulf Coast, provides winter habitat for 30,000-40,000 ducks and 40,000 snow geese. The refuge also contains about 4,000 acres (16 km2) of native coastal bluestem prairie. Changes in rainfall and runoff from upland regions could adversely affect sensitive coastal systems, and sea level rise would accelerate loss of wetlands and estuaries, eliminating breeding and foraging habitat for commercial, game, and threatened and endangered species.

Greenhouse gases

Air pollution occurs throughout major cities in Texas.

Texas emits more carbon dioxide into the atmosphere than any other state. And if Texas were a country, it would be the seventh-largest carbon dioxide polluter in the world . Texas's high carbon dioxide output and large energy consumption is primarily a result of large coal-burning power plants and gas-guzzling vehicles.

Action to address climate change

Clean cities

Texas is the home of the Alamo Area, Central Texas, Dallas/Fort Worth, East Texas, Greater Houston Regional), and South East Texas Clean Cities Coalitions.

Biofuel vehicle

The Adopt-A-School Bus Program, a cooperative partnership between the U.S. Environmental Protection Agency, state agencies, local elected officials, and corporate sponsors, was established as a nonprofit grant program to aid local school districts replacing their aging, diesel school bus fleets with new clean fuel buses. In an effort to ensure the longevity of the new buses, a portion of all grant money awarded is earmarked for fleet infrastructure and maintenance.

Renewable energy

Wind power in Texas

Wind power in Texas consists of many wind farms with a total installed nameplate capacity of 7,907 megawatts (MW) from over 40 different projects, as at April 2009. Texas produces the most wind power of any U.S. state, followed by Iowa with 2,883 MW. Wind energy accounts for 3.3% of all the energy used in the state and is growing.



The Texas Emissions Reduction Plan (TERP) provides grants for alternative fuel and advanced technology demonstration and infrastructure projects under the New Technology Research and Development (NTRD) Program, which provides incentives to encourage and support research, development, and commercialization of technologies that reduce pollution in Texas. For complete information on the types of projects and expenses that may be eligible for a grant, refer to the latest Request for Grant Applications and the NTRD Guidelines. The NTRD Program is administered by the Texas Environmental Research Consortium, with support from the Houston Advanced Research Center.

The Texas State Energy Conservation Office researches and assists public and private entities in securing grants to encourage the use of alternative fuels, including conversion of state and local government fleets to operate on compressed natural gas, liquefied petroleum gas, hydrogen, biodiesel, and bioethanol, and the use of hybrid electric vehicles.

Production fee

Ethanol and biodiesel producers are subject to a fee of $0.032 per gallon of ethanol or biodiesel produced in each registered production facility, imposed by the Texas Department of Agriculture.

For the purpose of the state regulation, ethanol is defined as ethyl alcohol that is at least 99% pure ethanol by volume that meets American Society of Testing and Materials (ASTM) specification D4806. Biodiesel is a monoalkyl ester derived from vegetable oils, rendered animal fats, or renewable lipids or a combination of those ingredients, and meets the requirements of ASTM PS 121, the provisional specification for biodiesel.
