Evidence proves that human behaviour has altered the composition of our atmosphere. By burning coal, oil, and gas to power our global and local economy, excess carbon dioxide, methane, and nitrous oxide have been released into the atmosphere. These "green house gases" accumulate and trap heat.
As a result, the world is getting warmer.
The current warming of the earth’s atmosphere is forecasted to accelerate the hydrological cycle, depicted here. This acceleration causes extreme climate fluctuations, including changes in frequency and intensity of storms and floods, increases in water temperatures, reduction in lake ice cover, changes in freshwater ecosystems, and forests.
What does this mean for Haliburton's Climate?
In 2016, the Muskoka Watershed Council published a report titled Planning for Climate Change in Muskoka. The authors used international studies to identify the following changes to our climate by the middle of this century.
This graph compares Muskoka’s mean daily temperature each month for a typical year during the present (1971-2000) climate (daily high and low temperature as blue lines) and that of a typical year during the mid-century (2041-2070) climate (daily high and low as red lines).
This graph depicts the mean monthly precipitation in Muskoka through a typical year under the current climate (blue: 1971-2000), compared with the mean monthly precipitation during the mid-century climate (red: 2041-2070). Total annual precipitation in the typical year at present is 1,028 mm rain or rain equivalent, and by mid-century is projected to be 1,127 mm.
