HomeClimate change will alter Manitoba's familiar climate characteristics. In the north, warmer temperatures could enhance tourism opportunities and reduce operating costs. On the other hand, milder temperatures may shorten the winter road season that Northern communities depend on to transport food and other supplies. Moreover, runways and other infrastructure built on the permafrost are vulnerable to shifting because of melting permafrost from warmer temperatures.
Sea-ice will likely change in extent, thickness and predictability. This could disrupt fish species, affect the length of the fishing season, and pose a safety risk for those who use the sea-ice as a hunting platform. This will have an impact on the fishing industry and people who support themselves through hunting.
Melting sea ice will open up marine shipping channels through the Arctic. This will bring more business and development to Northern Manitoba. However, this would also negatively impact marine ecosystems through increased activity and pollution.
Manitoba will likely experience more winter flooding because warmer temperatures would increase rain-on-snow precipitation and the frequency of winter thaws. The risk of flooding in the spring is predicted to continue and even increase the risk of damage to property and infrastructure.
The change in rainfall patterns and flood frequency could affect Manitoba's water supply systems leading to inceases in the cost of assuring a safe and reliable supply of clean drinking water.
There are many factors that could influence Manitoba's agricultural industry. More frost-free days would yield a longer growing season, lessen cold stress and reduce winterkill and open up opportunities for new crops. On the other hand, crops could be exposed to more damaging winter thaws. Drought and flooding could increase soil erosion as would more frequent freeze-thaw cycles.
