June 2015 has been the warmest months on the planet since the beginning of temperature readings … except Quebec.
According to Environment Canada, the province recorded temperatures “between one and two degrees” lower than the seasonal normal in most regions. Exceptionally, the month of May will be even hotter than in June this year.
Two important factors explain this fall.
The El Niño weather phenomenon, based on a concentration of warmer water than normal in the Pacific Ocean, has intensified and this has created extreme in the world. André Cantin, meteorologist with Environment Canada believes it can contribute to the fresh breeze that swept Quebec.
Since last summer, average temperatures in the North Pacific are also much warmer than normal. This has the effect of trace fresh air jets into northern British Columbia. Air masses then move to Quebec.
“This is really a consequence of warmer temperatures elsewhere. Temperatures are colder in Quebec, much like in the spring, while elsewhere on the globe, it is warmer, “says André Cantin. The Atlantic provinces were also affected by this slight cooling.
Yesterday, the National Oceanic and Atmospheric Administration (NOAA) announced that the average recorded last month on oceans and the land surface was 0.88 ° C above the average of the twentieth century for the month of in June, a record. This brand comes surpass that registered last year to 0.85 ° C, which was already a record.
According to an international climate report published last July by NOAA, the greenhouse gases emitted into the atmosphere, such as methane and carbon dioxide, have reached record in 2014.
This global warming has also had effects on Arctic ice. In June, the extent of ice observed satellite was 7.7% below the average observed over the last 25 years.
In 2014, the Intergovernmental Panel on Climate Change (IPCC) has also shown that the temperature of the land and ocean surfaces had increased globally by almost 1 degree Celsius since the beginning of the twentieth century, and that this increase go up to 2.5 degrees in parts of Africa, Asia and America.
