Any GHG - induced warming to date still lies within this range, but the projected man - made
warming over the coming century will be significantly larger and faster than recent natural fluctuations.
The result is new understanding of the factors that make some species more at risk due to the changing temperature and rainfall patterns that are
expected over the coming century.
Any ceiling effectively puts an absolute limit on global
emissions over the coming century, and the tricky part will be deciding who is entitled to make those emissions.
Waiting to get all these final, crucial facts could prevent countries from making very costly mistakes on how they manage fossil energy
resources over the coming century.
The ultimate contribution of clouds to global temperature trends is highly uncertain, but according to the best estimates is likely to be
positive over the coming century.
Revelle calculated that, at the emissions - rates of the time (assuming, like most of his predecessors, that these would likely remain constant), an increase of atmospheric carbon dioxide levels of around 40 % was
possible over the coming centuries.
The number of the strongest storms, Category 4 and 5 hurricanes, will likely
increase over the coming century, according to the latest National Climate Assessment.
The American Climate Prospectus addressed several key climate
impacts over the coming century, including increases in heat - related mortality, increases in the amount of coastal property exposed to flooding, declines in labor productivity, increases in energy expenditures, and declines in agricultural...
-- There is evidence, providing a basis for medium confidence, that droughts will intensify
over the coming century in southern Europe and the Mediterranean region, central Europe, central North America, Central America and Mexico, northeast Brazil, and southern Africa.
For now, the climatic effects of «clean energy» sources are trivial compared with those that spew out greenhouse gases, but if we keep on using ever more
power over the coming centuries, they will become ever more significant.
The new study combines estimates of populations at risk from sea - level rise within a migrations systems simulation to estimate both the number and destinations of potential sea - level rise migrations in the
U.S. over the coming century.
Both books chart global population, pollution and industrial and food production,
over the coming century according to a theoretical computer model of how these factors are thought to influence one another.
«The primary uncertainty in sea level rise is what are the ice sheets going to
do over the coming century,» said Mathieu Morlighem, an expert in ice sheet modeling at the University of California, Irvine, who led the paper along with dozens of other contributors from institutions around the world.
But unless such drastic action is taken in the next few years, we are headed for a very different world, one in which seas will rise by more than 5
metres over the coming centuries, and droughts, floods and extreme heat waves will ravage many parts of the world (see «Rising seas expected to sink islands near US capital in 50 years «-RRB-.
Some uncertainty remains around how much Africa's emissions will
grow over the coming century, he said, but relative to the United States, it's a question of whether Africa's per capita emissions will be «lower or much, much lower.»
A new study takes this concept into the realm of weather and climate, finding that global warming might sharply increase the odds of grey swan hurricanes and storm
surge over the coming century.
«suggesting that Arctic warming will continue to greatly exceed the global
average over the coming century, with concomitant reductions in terrestrial ice masses and, consequently, an increasing rate of sea level rise.»
If the models are right, however... The projected warming of 1.5 - 4.5
C over the coming century would be larger than any natural climate variation since the dawn of human civilisation.
Second, we investigate whether the cumulative emissions metric still holds for a class of emission pathways that do not assume that all emissions can be
mitigated over the coming centuries.
Let's see what the IPCC actually said: «This analysis focuses on three
periods over the coming century: an early - century period 2011 to 2030, a mid-century period 2046 to 2065 and the late - century period 2080 to 2099, all relative to the 1980 to 1999 means.
The modest global warming seen to - date (around 0.13 degrees Celsius per decade) is likely to
accelerate over the coming century - and models have even the US Corn Belt in the firing line.
With a significantly different orbital
configuration over the coming centuries it can not be expected that the behaviour of the NAO and AMOC would be similar to that during the Last Interglacial.
But note guest post here, in which I raised concerns about economic growth rates in the face of Peak Oil and (later) Peak
Gas over the coming century.
The IPCC report suggests that sea levels will rise somewhere between 0.18 m and 0.59
m over the coming century — hardly the sort of thing that will see skyscrapers swamped, islands sink or even low - lying poor cities inundated.
