Under
a more moderate emissions scenario, the county can expect nearly 20 weeks of cold temperatures each year, on average, by late century.

Even under a
more moderate scenario where greenhouse gas
emissions peak in 2040, 100 - year extreme sea levels could increase by 57 centimeters, or nearly 2 feet, on average, by the end of the century, with these events occurring every few years, according to study's authors.
However even the
moderate scenarios which have eventual stabilisation give
more warming than 0.8 C. Even in the extremely unlikely event that there is no further growth in
emissions, the current planetary energy imbalance (estimated to be almost 1W / m2)(due to the ocean thermal inertia) implies that there is around 0.5 C extra warming already in the pipeline that will be realised over the next 20 to 30 years.
Under a
moderate emissions scenario, cold days diminish
more slowly.
The red line with yellow range represents the warming to come over the next 90 years in one of the
more moderate IPCC business - as - usual
emissions scenarios (A1B - rapid global economic growth with a balanced emphasis on all energy sources).
The researchers» simulations suggest that because of sea level rise, Sandy - type surges have already become three times
more likely between 1800 and 2000, and will become 4.4 times
more likely by 2100, even under a
moderate greenhouse gas
emissions scenario.
We estimate that anthropogenic influence has caused a
more than 60-fold increase in the likelihood of the extreme warm 2013 summer since the early 1950s, and project that similarly hot summers will become even
more frequent in the future, with fully 50 % of summers being hotter than the 2013 summer in two decades even under the
moderate RCP4.5
emissions scenario.
