But ocean experts have increasingly warned that the direct chemical impact on marine life, as carbon dioxide dissolves in water and lowers its pH, could profoundly disrupt ecosystems by interfering with the growth of reefs and shell - forming plankton.

Other aspects of global warming's broad footprint on the world's ecosystems include changes in the abundance of more than 80 percent of the thousands of species included in population studies; major poleward shifts in living ranges as warm regions become hot, and cold regions become warmer; major increases (in the south) and decreases (in the north) of the abundance of plankton, which forms the critical base of the ocean's food chain; the transformation of previously innocuous insect species like the Aspen leaf miner into pests that have damaged millions of acres of forest; and an increase in the range and abundance of human pathogens like the cholera - causing bacteria Vibrio, the mosquito - borne dengue virus, and the ticks that carry Lyme disease - causing bacteria.

This pollution is impacting our marine ecosystems, wildlife such as seabirds, dolphins, fish, and turtles, and plastic fragments are even displacing plankton at the base of the food chain.

Bridlington, Whitby, and other English coastal towns have long depended on the North Sea fishery for food and income.2 But global warming is affecting plankton and changing the marine food chain, compounding the pressures of overfishing.3 The resulting disruption of the ecosystem could damage the fishing industry and hurt North Sea coastal communities from the United Kingdom to Scandinavia.
