A new report looks at flood risk and economic damages under different
global warming scenarios with temperature increases of 1.5, 2 and 4 °C.
The relationship they found between temperature and electricity demand was then used to see how demand would change given different
warming scenarios from global climate models.
Our planet is already free - falling into a
runaway warming scenario, global climate engineering is further fueling this scenario.
Changes in the distribution and species composition are already evident, but existing climate change projections are based
on warming scenarios from coarse resolution models.
Their sensitivity is assessed in several configurations under a high - end global
warming scenario over the time range 1976 — 2100.
Kremer and his colleagues then wanted to determine what would happen to phytoplankton distributions under
future warming scenarios.
In a recent book titled Six Degrees, which reviews the very latest science, Mark Lynas describes the world
under warming scenarios ranging from 1 °C (bad) to 6 °C (unimaginably bad).
In addition, according to the comment by the editor of Science, «The findings support the view that the Holocene Thermal Maximum, the Medieval Warm Period, and the Little Ice Age were global events, and they provide a long - term perspective for evaluating the role of ocean heat content in various
warming scenarios for the future.»
If today's worst - case global
warming scenarios of catastrophic melting of glaciers and ice sheets come to pass, sea levels could rise rapidly, wreaking all sorts of geological havoc «comparable with the most rapid increases in sea level that we've seen in the last 15,000 years,» McGuire said.
To this end, the study used a probabilistic approach to examine how sea levels would vary across the world's coasts under a worst -
case warming scenario by the year 2100.
Science writer Greg Laden wrote that the Duke study will receive «criticism from climate scientists» because it includes language that suggests it is assessing the likelihood of different
warming scenarios by predicting the amount of greenhouse gas emissions that will occur in the future, which it can't possibly know.
The study used simulations from the Community Earth System Model (CESM) run at the National Center for Atmospheric Research (NCAR) and examined
warming scenarios ranging from 1.5 degrees Celsius all the way to 4 degrees Celsius (7.2 degrees Fahrenheit) by the end of the century.
«I continue to believe that warming of Earth's surface temperatures from rising concentrations of greenhouse gases carries risks that society must take seriously,» he wrote, «even if we are lucky and (as my work seems to suggest) the most
catastrophic warming scenarios are a bit less likely.»
«Based on our analysis, a middle - of - the -
road warming scenario is more likely, at least for now» said Patrick Brown, a doctoral student in climatology at Duke University.
============================ PG: Thanks... the odds that it will be that devaluated are far greater than the
IPCC warming scenarios coming true.
That would drop the chances of the world achieving a 2 - degree C ceiling by 2100 from 66 percent (with aggressive mitigation from all nations) to about 10 percent, and move the
likeliest warming scenario up to 2.5 degrees C. «There's no wiggle room in the latter half of the century,» Sanderson says.
Under a
severe warming scenario, the researchers found that emergency room visits could increase 10 percent by 2090 in the studied regions as oak pollen seasons grow.
The Economist criticizes Nate Cohn at The New Republic and Brad Plumer at the Washington Post for clinging to support for policies that promise plenty of pain while offering no gain, especially since they acknowledge that time and reality have proven the
predicted warming scenarios to have been false.
Using the model Acclimate he contributes to studying the resilience of the global supply system leading to identification of possiblities and limits of global adaptation strategies along
different warming scenarios.
The paper also found that warming would be faster in the Northern Hemisphere compared with the Southern Hemisphere, and that if geoengineering were used to suppress an even more
dramatic warming scenario — say, 2 percent annual increases in CO2 concentrations — the rapid climate changes would be even faster after an abrupt suspension of the experiment.
«The habitat changes are bigger and faster in the [7 - degree] warming scenario,» Cloern said.
THC shutdown in a global
warming scenario offsets some of the global mean - warming, which might look like a good thing.
Another riddle was that previous research indicated that under global
warming scenarios Pacific Equatorial Trade winds would slow down over the coming century.
These assumed that the largest decreases in rainfall would be in winter and spring (decreases of 5 % and 11 % between 1990 and 2030 on the low and high global
warming scenarios respectively), but rainfall was fractionally HIGHER in winter / spring in the more recent period (1995 - 2006) than in the previous 11 - year period.
But it's not just politicians and environmental groups and scientists making the warnings to business, it's also established corporate entities such as the global accounting giant PwC, which this week released its latest climate index, warning that the world was hurtling towards a
6C warming scenario, unless it accelerated its efforts to decarbonise by a factor of four, and maintained that for around four decades.
GOAL 2: Project a diminished arctic sea - ice cover with
multiple warming scenarios and to examine key linkages among atmospheric forcing, sea - ice processes, and oceanic processes in an ice - diminished Arctic Ocean and the adjacent seas.
