Globally speaking, the average annual temperature has increased in recent years. A recent report from National Ocean and Atmospheric Administration – NOAA – states that 9 out of 10 hottest Junes ever have occurred since 2010, and Canada has a significant contribution in this trend (www.noaa.gov). Since 1880, the Earth has warmed up 1 oC (www.glimate.nasa.gov). This rate is different in various areas around the globe. However, Canada has shown to be among the countries that are warming up faster than others (www.climateatlas.ca). Canada has warmed up 1.7oC since 1948, which is two times faster than the global rate (Canada’s changing climate report – CCCR -, 2019). The situation in Northern Canada is even more serious, as the Northern areas are warming up three times faster than the global rate (CCCR, 2019).

In order to mobilize the public to cooperate in controlling the climate crisis, it is necessary to let them know how serious and fast the climate has evolved recently. To that end, the recent behavior of climate in Bonfield can be demonstrated using the long-term weather records of the North Bay airport. The analysis has been conducted in the Nipissing University. Moreover, climate change studies were performed by an external party for the North Bay Mattawa Conservation Authority – NBMCA -. According to these studies, the temperature has followed an increasing trend, as can be seen in Figure 1.

Obviously, since 2000 mean annual temperature values are larger than the rest of the recording period. The average annual temperature has topped 5oC nine times, eight of which happened since 1998 (Nipissing University Report, 2017). This is in accordance with the fact that 17 out of 18 global warmest recorded years have occurred since 2001 (www.climateatlas.ca). A similar increasing trend has been observed for annual precipitation (rainfall and snowfall) as well. Only four years displayed annual precipitation more than 1200 millimeter, all after 1997. According to the report prepared by Stantec (engineering services) for NBMCA, precipitation trends higher around 2.4% per decade since the 1950s.

All these observed trends suggest an increasing trend in both precipitation and temperature in North Bay. These trends can be transferred to Bonfield as Bonfield and North Bay have a similar climate. What does the climate in Bonfield look like? Can we project these trends to the future?

These questions will be answered in future updates. Now, you are invited to enjoy this music while reflecting on climate change:
