The problem with climate change isn’t just the temperature. It’s how fast the climate is changing.

Historically, Earth’s climate changes have generally happened over thousands to millions of years. Today, global temperatures are increasing by about 0.36 degrees Fahrenheit (0.2 degrees Celsius) per decade.

Imagine a car speeding up. Over time, human activities such as burning fossil fuels, have increased the amount of greenhouse gases in the atmosphere. These gases trap heat from the Sun. This is like pressing the gas pedal. The faster the driver adds gas, the faster the car goes. 

The 21^st century has seen a dramatic acceleration in the rate of climate change, with global temperatures rising more than three times faster than in the previous century.

The faster pace and higher temperatures are changing habitat ranges for plants and animals. In some regions, the pace of change is also throwing off the delicate timing of pollination, putting plants and pollinators such as bees at risk.

Some species are already migrating

Most plant and animal species can tolerate or at least recover from short-term changes in climate, such as a heat wave. When the changes last longer, however, organisms may need to migrate into new areas to adapt for survival.

NASHVILLE — A bill slashing regulations for an estimated 80 percent of Tennessee’s non-federally protected wetlands headed to Gov. Bill Lee’s desk this week after receiving approval from the General Assembly.

The bill’s West Tennessee Republican sponsors — Rep. Kevin Vaughan and Sen. Brent Taylor — said the legislation removes onerous and seemingly subjective mitigation requirements for landowners and developers. 

Environmental advocates and scientists said the legislation paves the way for the destruction of Tennessee’s natural resources.

The bill passed 71-21 with one abstention in the House, and 25-6 in the Senate.

Since the 1970s, wetland regulations in Tennessee have required developers and landowners to seek permission from the state before draining or altering wetlands. The swampy areas can host diverse species, soak up rain water and filter it as it seeps into groundwater tables, recharging aquifers. Alterations to wetlands required developers to pay for mitigation — efforts to preserve or restore other wetlands nearby.

EnSafe planted more than 50,000 trees to restore portions of this 250-acre wetland, creating credits for developers to purchase to offset destruction of wetlands elsewhere.  Karen Pulfer Focht for Tennessee Lookout

Interests of all stripes push to preserve state wetlands protections against pro-developer pressure

LEWISBURG — Fourth-generation Middle Tennessee cattle farmer Cole Liggett lined up with scientists and environmental advocates in March to urge Tennessee lawmakers not to gut the state’s historically strong protections for wetlands.

Wetlands protection has been good business for Liggett. In addition to raising cattle, he’s a manager at Headwaters Reserve, a firm that developers pay to preserve and restore wetlands and streams so they can destroy them elsewhere, called mitigation banking. If lawmakers follow through on a plan to deregulate an estimated 80 percent of the state’s isolated wetlands, that will upend the industry in Tennessee and drive up prices for developers still required to pay for mitigation, Liggett testified.

Liggett works in a growing industry that operates more than 2,500 mitigation banks nationwide, earning an estimated $3.5 billion in revenue in 2019, according to a 2023 study funded by the Ecological Restoration Business Association. 

The industry is built on demand spurred by the 1972 U.S. Clean Water Act, which requires developers to offset their damage to wetlands by building or restoring wetlands nearby.

But recent federal actions to shrink the scope of that law are pushing states to choose how strictly they will regulate wetlands. The consequences of those decisions not only threaten further degradation of land, water and wildlife, but also the fortunes of an industry that has made a big business out of conservation.

One of the goals behind a recent partnership among UTIA and state agencies is the promotion of heartier food species such as this oak. The new five-year agreement between the UTIA Tree Improvement Program, the Tennessee Division of Forestry and the Tennessee Wildlife Resources Agency focuses on developing locally adapted and genetically improved seed for future Tennessee forests.  Allison Mains/UTIA

KNOXVILLE — A new, five-year agreement establishes how the state of Tennessee and a program in the University of Tennessee Institute of Agriculture will study and produce tree seedlings to promote the protection and conservation of Tennessee forests.

The UTIA Tree Improvement Program (UT-TIP), the Tennessee Department of Agriculture Division of Forestry (TDF) and the Tennessee Wildlife Resources Agency (TWRA) partnered on the agreement.

“Honoring our land-grant mission, we are excited about this partnership to responsibly research, develop, manage and conserve forest resources across the great state of Tennessee,” said Keith Carver, UTIA senior vice chancellor and senior vice president.

UT-TIP manages numerous seed orchards in East, Middle and West Tennessee with help from state and federal partners. It uses the orchards to provide the East Tennessee Nursery with locally adapted and genetically improved seed.
