Although these towns are large enough to be considered cities, they are not incorporated as such.

{{Main|Climate change in Vermont}}

Climate change in Vermont encompasses the effects of climate change, attributed to man-made increases in atmospheric carbon dioxide, in the U.S. state of Vermont.

The state is already seeing effects of climate change that affect its ecosystems, economy and public health. According to the Vermont state government, rainfall has significantly increased in the last 50 years, storms and flooding have increased, and winters have become warmer and shorter.{{Cite web|url=https://climatechange.vermont.gov/|title=Climate Change in Vermont {{!}} Climate Change in Vermont|website=climatechange.vermont.gov|access-date=2019-11-23}} These changes have led to significant impacts on both the winter tourism industry,{{Cite web|url=https://climatechange.vermont.gov/our-changing-climate/what-it-means/tourism|title=Tourism and Recreation {{!}} Climate Change in Vermont|website=climatechange.vermont.gov|access-date=2019-11-23|archive-date=May 6, 2021|archive-url=https://web.archive.org/web/20210506014315/https://climatechange.vermont.gov/our-changing-climate/what-it-means/tourism|url-status=dead}} and a decline in critical agricultural and woodland industries like maple sugaring.{{Cite web|url=https://climatechange.vermont.gov/our-changing-climate/what-it-means/farms-forests|title=Farms and Forests {{!}} Climate Change in Vermont|website=climatechange.vermont.gov|access-date=2019-11-23|archive-date=May 6, 2021|archive-url=https://web.archive.org/web/20210506004649/https://climatechange.vermont.gov/our-changing-climate/what-it-means/farms-forests|url-status=dead}}

Subsequently, about {{Nowrap|400 million}} years ago, the second mountain building period created Green Mountain peaks that were {{convert|15000|-|20000|ft}} tall, three to four times their current height and comparable to the Himalayas. The geological pressures that created those peaks remain evident as the Champlain Thrust, running north–south to the west of the mountains (now the eastern shore of Lake Champlain). It is an example of geological fault thrusting where bedrock is pushed over the newer rock formation.

As a result of tectonic formation, Vermont east of the Green Mountains tends to be formed from rocks produced in the Silurian and Devonian periods, and western Vermont mainly from the older Pre-Cambrian and Cambrian material.{{cite web |url=http://www.anr.state.vt.us/dec/geo/images/gengeo52.pdf |title=Generalized geologic map of Vermont |access-date=February 23, 2012 |archive-date=April 5, 2012 |archive-url=https://web.archive.org/web/20120405135709/http://www.anr.state.vt.us/dec/geo/images/gengeo52.pdf |url-status=dead }} Several large deposits within the state contain granite.{{cite web |title=Granite {{!}} Department of Environmental Conservation |url=https://dec.vermont.gov/geological-survey/resources-energy/minres/granite |website=dec.vermont.gov |publisher=Department of Environmental Conservation |access-date=March 3, 2020}} The remains of the Chazy Formation can be observed in Isle La Motte.

Wildlife has suffered because of human development of the state. By the mid-19th century, wild turkeys were exterminated in the state through overhunting and destruction of habitat.

Vermont is in the temperate broadleaf and mixed forests biome. Much of the state, in particular the Green Mountains, is covered by the conifers and northern hardwoods of the New England-Acadian forests. The western border with New York and the area around Lake Champlain lies within the Eastern Great Lakes lowland forests. The southwest corner of the state and parts of the Connecticut River are covered by northeastern coastal forests of mixed oak.{{cite journal|author1=Olson, D. M |author2=E.

Invasive wild honeysuckle has been deemed a threat to the state's forests, native species of plants, and wildlife.{{cite news|first=Larson|last=Dimarlo|title=Using undiluted herbicides to fight invasive species|newspaper=Burlington Free Press|location=Burlington, Vermont|pages=2D |date=June 13, 2010}} Many of Vermont's rivers, including the Winooski River, have been subjected to man-made barriers to prevent flooding.{{citation needed|date=October 2017}}

Climate change appears to be affecting the maple sugar industry. Sugar maples have been subject to stress by acid rain, asian longhorn beetles, and pear thrips. In 2011, the deer herd had grown too large for habitat, and many resorted to eating bark to survive the winter, destroying trees in the process. In addition, the sugar maples need a certain period of cold to produce sap for maple syrup. The time to tap these trees has shrunk to one week in some years. The tree may be replaced by the more aggressive Norway maples, in effect forcing the sugar maples to "migrate" north to Canada.{{Cite news | first=Keith | last=Winston | title=Wildlife habitats shift as winters grow warmer | url=http://www.floridatoday.com/article/20111129/COLUMNISTS01/311290015/Keith-Winsten-Wildlife-habitats-shift-winters-grow-warmer | newspaper=Florida Today | location=Melbourne, Florida | pages=7B | date=November 29, 2011 | archive-url=https://web.archive.org/web/20111130061627/http://www.floridatoday.com/article/20111129/COLUMNISTS01/311290015/Keith-Winsten-Wildlife-habitats-shift-winters-grow-warmer | archive-date=November 30, 2011 | url-status=dead }}
