When we think of global climate change, what comes to mind? Rising seas? Melting glaciers? Shrinking sea ice? How about diminishing ocean oxygen levels?
Sea levels are rising around the world because of melting ice as well as warming waters since water expands as its temperature goes up. Average sea levels around the world are predicted to rise by about three feet by the end of the century as a consequence of the warming climate.
Coastal floodplains across the southeastern and mid-Atlantic regions of the United States are at the leading edge of climate change’s effect on what were largely freshwater ecosystems. Because of the low elevation and flat or gently sloping characteristics of coastal forests in these areas, they are among the most vulnerable globally to saltwater intrusion.
The conventional aquaculture industry has often been associated with many of the same problems that beset land-based agriculture: creating sterile monocultures, fouling the environment with pesticides, antibiotics and organic pollutants, and spreading diseases.
The top of the world is turning from white to blue in the summer. The ice that has long covered the north polar seas is melting away.
