Acidity also thins the exoskeletons of many species of plankton, which could reduce the population of those plankton and the fish that feed on them and alter the entire marine food web. For example, young salmon eat some of the types of shellfish and plankton that are vulnerable to acidification. Rising ocean temperatures may also harm marine ecosystems. Warming waters can increase the frequency of toxic algae blooms (such as “red tide”) that cause shellfish poisoning and lead to closures of beaches and shellfish beds. Warmer waters also allow invasive species from southern waters to move northward".

233:"The combination of more fires and drier conditions may expand deserts and otherwise change the landscape in the dry eastern portion of the state. Many plants and animals living in arid lands are already near the limits of what they can tolerate. Warmer temperatures and a drier climate would generally extend the geographic range of the Great Basin desert. In some cases, native vegetation may persist and delay or prevent the expansion of the desert. In other cases, fires or livestock grazing may accelerate the conversion of grassland to the desert in response to the changing climate. For similar reasons, some forests may change to desert or grassland".

138:"Oregon's coastal waters are vulnerable to acidification. The ocean here is more acidic than most of the ocean, because nearby currents bring relatively acidic water from the deep ocean to the surface, especially during spring and summer. Increasing acidity impairs the ability of some types of shellfish to capture minerals in the water to build their shells, which can lead to thinner shells—or even prevent shells from forming. At the Whiskey Creek Hatchery in
222:"Higher temperatures and a lack of water can also make trees more susceptible to pests and disease, and trees damaged or killed burn more readily than living trees. For example, climate change is likely to increase the area of pine forests in the Northwest infested with mountain pine beetles in the next few decades. Pine beetles and wildfires are each likely to decrease timber harvests. Increasing wildfires also threaten homes and pollute the air".
254:"Climate change may also pose challenges for livestock and crops. Higher temperatures cause cows to eat less, grow more slowly, and produce less milk, and in extreme cases may threaten their health. Some farms may be harmed if more hot days reduce crop yields, or if the decline in summer streamflow reduces the water available for irrigation. Other farms may benefit from a longer growing season and the fertilizing effect of carbon dioxide".

Mudflats, marshes, and other tidal wetlands provide habitats for birds and fish. As water levels rise, wetlands and beaches may be submerged or squeezed between the rising sea and structures erected to protect coastal development".
