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. 

What can YOU, and those around you, do to make your lifestyle more sustainable?

Today is a good opportunity to make a resolution or a promise to yourself and those around you to adopt a new habit or practice that will reduce your environmental impacts. Perhaps, you have already taken such a step a while ago and you may now scale it up or add something else to it?

EarthSolidarity!™ is focusing on individual and small-group initiatives that facilitate practical, local, down-to-Earth actions that can readily be replicated by many and thus add up to significant improvements in the community, the bioregion and — through equivalent locally and regionally tuned initiatives — contribute to our national and even global environmental health.

You may have found that it’s not so difficult, and perhaps you discovered some ways of making it easier or more successful than you thought possible at first. If so, please This email address is being protected from spambots. You need JavaScript enabled to view it..

Encourage those next to you to adopt the same or similar action. We are looking for leaders like you that are willing to help organize or just advise small environmental action groups at the neighborhood level or within local businesses and organizations.

National parks advocate and former Smokies official warns of funding shortfalls as closures continue, concerns persist, and people resist

KNOXVILLE — Funding for national parks has never amounted to much, and the federal government will cut even more if people don’t speak out in defense of the country’s natural and ecological crown jewels.

That was the message from Phil Francis, chairman of the Coalition to Protect American National Parks and former acting superintendent of Great Smoky Mountains National Park. He spoke to an audience at Knoxville’s Schulz Bräu Brewing Company hosted by Discover Life in America. Francis said that due to rising concerns his organization grew from 500 members to over 4,000 during the Trump administration. The coalition, he said, includes many people like himself who used to work for the park system, including the former superintendent of Acadia National Park.

Francis advocated that others should lobby government officials to continue to support the parks.

“If you don’t speak up, it makes it a lot more difficult,” he told the audience.

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.
