causing regional warming of the western Antarctic Ocean.
Models indicate increased boreal forest reduces the effects of snow albedo and
causes regional warming.
Not exact matches
As
regional warming caused an increased number of trees to die, there would be less living trees to absorb carbon dioxide from the atmosphere.
Ultimately, there is limited value in debating whether human - driven
warming has
caused the uncloaking of any particular Arctic island, the retreat of a snowfield atop any single mountain — even one as charismatic as Kilimanjaro — or the breakup of a particular ice shelf in Antarctica, or any other
regional anomaly.
The point I am trying to make is «when it is claimed that DO events represent a much larger and more rapid climate change than anthropogenic global
warming,» perhaps DO events do
cause rapid
regional climate change larger and more rapid than anthropogenic global
warming generally.
The NCA and CSSR simply pick out the worst rising variables, global or
regional, that might be related to global
warming (which they also assume is human
caused).
As this map suggests, CO2 -
caused «global»
warming is highly suspect since normal
regional weather / climate oscillations easily overwhelm its impact.
The authors conclude that the there is a higher retreat - rate for marine terminating glaciers in the recent
warm period; in the 1930s when there is a natural mode of variability active that
caused regional temperatures around Greenland to be anomalously
warm, there was a higher retreat rate for land - terminating glaciers (the lower retreat rate today is in part because they are currently smaller).
We have been investigating the
causes and impacts of these trends, with a focus on determining if the
regional warming and cooling patterns result from natural variability or are due to human activities.
1) Post-1950s stratospheric cooling 2) Post-1950s mesospheric cooling 3) Post-1950s thermospheric cooling 4) Horizontal /

warming [DOI: 10.1175 / BAMS - D -11-00191.1, pages 1683 and 1684] 5) Exclusion of other likely causal factors, such as the Sun [ex: solar - induced
warming causes warming of the stratosphere, mesosphere, and thermosphere, yet scientists observed cooling in these layers].
... «When you hear a phrase like he said, «the highest ever,» you know, «off the charts,» «record setting,» that's a good sign that on top of a whatever local weather patterns there are or
regional like El Nino, global
warming, fossil fuel driven climate change is putting its finger on the scale and juicing the atmosphere and
causing the even bigger weather event than you would have otherwise seen.»
Theses lines of evidence include: — Post-1950s stratospheric cooling — Post-1950s mesospheric cooling — Post-1950s thermospheric cooling — Horizontal /

16 * Melting Glaciers and Rising Sea Levels Over the last century glaciers have been melting worldwide Antarctica ice sheet temp has risen 6 degrees As ice sheets and glaciers melt, sea level rises *
Regional Temp Changes Changes in

causes regions to
warm and become very dry.

Watering your lawn
causes some localized
warming and in a place like Flagstaff everyone does it changes
regional temperatures.]
This is known via various lines of evidence, including: — Post-1950s stratospheric cooling — Post-1950s mesospheric cooling — Post-1950s thermospheric cooling — Horizontal /

Increased snow cover last year, cooler temperatures, higher temperatures in the 1920's and 1930's, etc. are all discounted as
regional or temporary, because of the fundamental belief that the earth is
warming due to man - made
causes.
The one thing about Dr. Meier's answers that interested me was this idea he has that
regional warming can be natural and cyclical, but that if it is world wide than it has to be
caused by manmade sources.
If maximum temperatures have not exceeded that earlier peak, CO2 has not
caused any
regional «accumulation of heat» due to the hypothesized radiative imbalance; and Parmesan is still very wrong for suggesting global
warming was extirpating butterflies.
I've been a bit impressed in recent years (not) at the ability of politically endorsed science to be able to use data from these areas and regurgitate it as global data rather than
regional data, or to relate it to human
caused warming.
Not only have its models been conclusively wrong about CO2 -
caused global
warming over the last 15 years, but the climate models»
regional predictions are often diametrically opposite of reality.
The recent
warming in the Arctic anyway is not direct from
regional CO2, as the observed
warming needs a heat / radiation unbalance which is an order of magnitude larger than the direct change in radiation
caused by CO2 increases...
Temperatures may rise to levels where land ice melts, and feedbacks created by sea ice loss reinforce
regional Arctic
warming, which in turn could
cause more land ice to melt.
«What we're seeing is stark evidence that the gradual temperature increase is not the important story related to climate change; it's the rapid
regional changes and increased frequency of extreme weather that global
warming is
causing.
However, calculations showed that this subtle effect should
cause no more than a small
regional warming.
