"We are already seeing the effects of widespread warming in Canada", said Bush. However, a report published by the United Nations in March 2018, titled "Perspectives on Climate Change Action in Canada - A Collaborative Report from Auditors General", predicted that Canada's emissions in 2020 will be nearly 20 percent above its target level.
Warming is happening even faster in winter, with a 3.3C average temperature increase between December and February, leaving southern Canadians with more winter rain and northern Canadians with melting permafrost and less sea ice.
The report was produced in collaboration with scientists from Environment and Climate Change Canada, Fisheries and Ocean Canada, Natural Resources Canada, and university experts.
"Scenarios with limited warming will only occur if Canada and the rest of the world reduce carbon emissions to near zero early in the second half of the century and reduce emissions of other greenhouse gases substantially".
"Climate change is real, and Canadians across the country are feeling its impacts", Catherine McKenna, Minister of Environment and Climate Change, said in a press release.More news: ‘Marxist’ Corbyn ‘extremely dangerous’, says minister as Government seeks deal
Precipitation is projected to increase for most of Canada, on average, although summer rainfall may decrease in some areas. In addition, the findings revealed that extreme high temperatures will become "more frequent and more intense", increasing the frequency of heatwaves, wildfires and droughts.
"This report is a wakeup call for all Canadians".
Gelfand also looked at the current impact of invasive aquatic species, most of which are accidentally introduced to Canadian waters on the hulls of ships coming from global waters and many of which harm native marine life after arrival.
Oceans surrounding Canada have warmed, become more acidic, and less oxygenated, which threatens the health of marine ecosystems.
In the high emission scenario, the sea ice cover in the Northern Hemisphere will see essentially ice-free conditions in September and a global rise in mean sea level could range between 36 to 45 cm.More news: Brexit: MPs talk ‘absolute nonsense’ while objecting to talks - leader comment
The Canadian government says it will meet the Paris target of cutting emissions to 30 percent below 2005 levels by 2030 despite the fact that a number of official reports indicate the country is unlikely to meet its reduction targets without significant effort.
There are, of course, climate change deniers, most notably U.S. President Donald Trump, who reject the notion that pollution has an effect on climate and who mistakenly confuse climate with weather.
Civil society appeared to be at a "tipping point" on the issue with public opinion moving in support of governments taking action. The development of Canada's Changing Climate Report also benefited from consultations with a broad range of assessment users, such as governments, Indigenous organizations and academia.
The carbon tax will be added to the cost of fuel - 4.4 Canadian cents per litre initially - equivalent to 20 Canadian dollars per tonne of carbon produced, more than doubling by 2022.
The measure has angered conservatives, a few months ahead of national parliamentary elections in October.More news: Turkish charity continues to support cyclone-hit Mozambique
