After posting nearly -20 degrees Celsius over the weekend, the temperature will experience a spectacular jump over the next 24 hours in the Ottawa and Gatineau region. The thermometer could reach 14°C on Tuesday. A warm weather that could have harmful effects on natural systems. Your spring jacket may come out of the closet earlier than expected this year. Tuesday and Wednesday will be the hottest days recorded in the Federal Capital Region, based on data dating back to the 1870s. The previous record dates back to February 27, 2000 with a temperature of 12.4°C. This mild weather led the Federal Capital Commission (NCC) to close the Rideau Canal skating rink for this season on Sunday. The month of February 2024 was warmer than average, with a temperature of -4.3°C, and is part of a year marked by milder weather. Out of the last twelve months, nine were above average. Source: CBC This rise in temperatures has multiple causes including climate change as well as the El Niño phenomenon associated with higher temperatures. It's an El Niño winter, which gives us a very high chance of having above normal temperatures. So that’s what we’re seeing this winter and that’s what we saw last week and that we’ll see the week to come, explains Environment Canada meteorologist Steven Flisfeder.

He adds that the temperature variations observed in recent days could lead to thunderstorms on Tuesday and Wednesday, a rare phenomenon at this time of year. With the warm weather this winter, the snow has been less abundant. The Federal Capital Region received less than half the snow that fell this time last year. This reduction in snowpack could have a detrimental effect on natural systems, according to Rideau Valley Conservation Authority director of engineering services Brian Stratton. One who closely monitors the river systems around Ottawa notes that the lack of snow could lead to drought in the coming months, although rain in the spring could change the situation. We don't know anything yet, but everything indicates that this [drought] could occur because precipitation and soil moisture will be limited as spring approaches. A quote from Brian Stratton, director of engineering services at the 'Rideau Valley Conservation Authority The engineer says that drinking water is not a source of concern, wells and the Ottawa River being abundant. However, the possible drought could have repercussions on agriculture and aquatic life. The lack of snow also worries the soil scientist , now retired, from Agriculture Canada, Ed Gregorich. The man who has devoted his entire career to the study of soils explains that snow provides an important nutrient: nitrogen. However, significant melting – like the one we experienced this year – means this element is lost in runoff.

A lack of nitrogen could mainly impact forests, according to the pedologist.
For agricultural soil, the farmer can manage this. But it is in natural ecosystems that this can have a detrimental effect. The forests then become poorer in nutrients, explains Ed Gregorich. more often are worrying, according to the pedologist. Indeed, this phenomenon modifies the normal process in the soil causing the release of greenhouse gases (GHG).
These GHGs could in the medium term increase the temperature on the earth's surface.
