Climate Change Scenarios for Sudbury

Scientists, through the use of climate models, can project future climate conditions (like average temperature and precipitation) due to climate change. This gives us an idea of what we (or our children) can expect in 20 to 50 years.

Climatic History of Greater Sudbury:

Between 1895 and 1999, temperatures in the Great Lakes basin have risen 0.7 ºC. During this time, the city saw the arrival of the railway, the growth of the mining industry and witnessed the loss of forests due to forestry and mining activities.

In 2050 you can expect: 

An increase of 2-3 ºC in average annual temperature

A shorter snowfall season

More frequent and intense extreme events

A 10-15% increase in annual precipitation

More rain and less snow

More extreme heat days and fewer extreme cold days:

35-40 more days per year with a maximum temperature higher than 25 ºC

10-15 more days per year with a maximum temperature higher than 30 ºC

0-5 more days per year with a maximum temperature higher than 35 ºC

30-35 more freeze-free days per year

Increased variability of wet and dry periods (duration, timing, severity)

Longer growing season:

Start date about 15 days sooner

End date about 15 days later
