in southern ontario to show primarily two things: one is that summer temperatures are not increasing, only winter temperatures are increasing therefore it is not in fact getting warmer it is only getting less cold (there is no argument that the seasonally averaged trend is rising); two is that the slight averaged rise is extremely small compared to the daily and seasonal temperature fluctuations.

Model projections for precipitation changes are less certain than those for temperature.12, 2 Under a higher emissions scenario (A2), global climate models (GCMs) project average winter and spring precipitation by late this century (2071 - 2099) to increase 10 % to 20 % relative to 1971 - 2000, while changes in summer and fall are not expected to be larger than natural variations.

For increases in global average temperature of less than 1 to 3 °C above 1980 - 1999 levels, some impacts are projected to produce market benefits in some places and sectors while, at the same time, imposing costs in other places and sectors.

The IPCC has a confidence level > 90 % that less than 50 % of the observed increase in global average temperatures since the mid-20th century is the result of non-anthropogenic external forcings and internal natural variability within the climate system.

In order to avoid the most devastating impacts of global warming, climate scientists have warned that emissions of carbon dioxide and other greenhouse gases need to be cut in order to keep the increase in average global temperature to less than 3.6 degrees Fahrenheit (2 degrees Celsius).

Less abrupt changes would occur around the world as average temperatures increased.

If the Sun is not the cause of the slight increases in average temperature observed and it is truly CO2 «trapping heat» then we have the unusual paradox of a system radiating less while it is warming.

Climatologist Dr. Pielke Sr. rips RealClimate.org's claims: «It is straightforward to shed doubt on Gavin Schmidt's (and the IPCC) claim» — «If the increase in anthropogenic greenhouse gas concentration were so dominate we would expect the global average [annual] lower troposphere temperature to more - or less monotonically continue to rise in the last decade or so.
