how does climate change affect water in canada?
448471
A warmer climate is already reducing the ice cover over the Great Lakes every winter. ... In the long run, warmer temperatures in both winter and summer are expected to lower water levels in the Great Lakes. Lower lake levels would damage ecosystems and reduce water quality.

Climate influences the landform processes that shape Scotland's mountains, rivers and coasts, and maintain our habitats, ecosystems and landscapes. ... Increasing ocean temperatures and ocean acidification are the main consequences of climate change and rising CO2 levels on the marine environment.
304808
The amounts and frequency of rain will change. Winters will be wetter and summers will become hotter and more prolonged. There will be increased local flooding with more flash flooding occurring. This will result in increased pressure on water resources in the UK.
1224683
The impacts of climate change on our oceans include shifts in temperature, acidification, deoxygenation and changes in ocean currents. ... Shifting ocean currents and warming waters are changing the distribution of fish stocks and altering the structure of ecosystems.
80227
Although more rainfall can add to fresh water resources, heavier rainfall leads to more rapid movement of water from the atmosphere back to the oceans, reducing our ability to store and use it. Warmer air also means that snowfall is replaced by rainfall and evaporation rates tend to increase.

Climate change is modifying fish distribution and the productivity of marine and freshwater species. ... The effect of sea level rise means that coastal fishing communities are significantly impacted by climate change, while changing rainfall patterns and water use impact on inland freshwater fisheries and aquaculture.

Impacts of a Changing Climate Rising global temperatures threaten human health, increase the risk of some types of extreme weather, and damage ecosystems. And as the oceans warm and polar ice caps melt, sea levels are rising, endangering coastal areas.

Seasonal changes in precipitation and temperature affect soil moisture, evaporation rates, river flows, lake levels, and snow cover. Leaves fall and plants wither as cold and dry seasons approach. These changes in vegetation affect the type and amount of food available for humans and other organisms.

Global warming is projected to have a number of effects on the oceans. Ongoing effects include rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification.

Increased pollution levels in waterways also lead to a rise of algal blooms, which we'll address below. Climate change is causing air temperature to rise, which provokes corresponding water temperature increases in lakes, reservoirs, and streams.

Average annual water flow dropped more than 11 percent over the last century due to warming. With climate change shrinking snow cover in the Colorado River Basin, the ground absorbs more sunlight. That causes more water to evaporate, leaving less to feed the Colorado River that brings water to millions of people.

Impacts in Canada. Atlantic Canada is one regions in Canada most threatened by global climate change. The region will experience more storm events, increasing storm intensity, rising sea levels, storm surges, coastal erosion and flooding from a warming in global temperatures.
372979
Changes in water temperature can affect the environments where fish, shellfish, and other marine species live. As climate change causes the oceans to become warmer year-round, populations of some species may adapt by shifting toward cooler areas. ... Oceans are becoming more acidic.

Warming oceans alter currents Climate change impacts ocean temperatures as well as wind patterns — taken together, these can alter oceanic currents.

For example, a warmer climate causes more water to evaporate from both land and oceans; in turn, a warmer atmosphere can hold more water – roughly four percent more water for every 1ºF rise in temperature. Changes like this are expected to lead to specific, and in many cases negative, consequences.

Global climate change affects a variety of factors associated with drought. There is high confidence that increased temperatures will lead to more precipitation falling as rain rather than snow, earlier snow melt, and increased evaporation and transpiration.

Climate change increases water and air pollution which can cause and aggravate chronic respiratory disease, such as asthma. Increased temperatures due to climate change lead to increased ground-level ozone, which cause airway inflammation and damages lung tissue.
