Climate change in Maryland encompasses the effects of climate change, attributed to man-made increases in atmospheric carbon dioxide, in the U.S. state of Maryland.
The United States Environmental Protection Agency reports that the state's climate has warmed one to two degrees Fahrenheit in the last century, heavy rainstorms occurred more often, and sea level rose eroding beaches, submerging low lands, and increasing the salinity of estuaries and aquifers. The changing climate will increase flooding, harm ecosystems, disrupt both agriculture and aquaculture, and increase certain risks to human health.[1]
