Global warming is affecting oceanic circulation. Cold water-loving Maine shrimp, lobsters and other species are migrating to deeper waters or further north. Pursuing these species leads our fisherfolk further from shore, into deeper waters, raising both their expenses and their risks. Ocean warming also affects the ocean’s affinity for CO2 absorption, increasing the acidity. The U.N. report on global warming, which warns that Earth’s temperatures in about a decade will probably blow past a level of warming that world leaders have sought to prevent. Perhaps the fastest-acting intervention is to impose a price on fossil fuels, a so-called carbon fee. ~ David Smith, Portland
