As East Coast residents, we can witness
these temperature changes on a larger scale.

New research published this week in the Journal of Climate reveals that one key measurement —
large -
scale upper - ocean
temperature changes caused by natural cycles of the ocean — is a good indicator of regional coastal sea level
changes on these decadal timescales.
For significant periods of time, the reconstructed
large -
scale changes in the North Pacific SLP field described here and by construction the long - term decline in Hawaiian winter rainfall are broadly consistent with long - term
changes in tropical Pacific sea surface
temperature (SST) based
on ENSO reconstructions documented in several other studies, particularly over the last two centuries.
As for additional topics, perhaps a brief explanation
on why confidence in attribution (and prediction) of
temperature change is strongest at
large scales and weakest at small
scales, ie something about the issue of signal to noise relative to spatial
scale.
The paper he wrote together with Friis - Christensen in which he found a correlation between solar activity and clouds had a «slight» flaw: it ignored that the period of the study coincided with a big El Nino, and that
large scale changes in ocean surface
temperature are going to have an effect
on cloud formation.
As for exagerating or minimizing the current
temperature trend through choice of
scale, it really depends
on wether or not 1oC is a
large change to occur over one century and all evidence suggests that it is.
The overall level of consistency between attribution results derived from different models (as shown in Figure 9.9), and the ability of climate models to simulate
large -
scale temperature changes during the 20th century (Figures 9.5 and 9.6), indicate that such model differences are likely to have a relatively small impact
on attribution results of
large -
scale temperature change at the surface.
SkyPower, the world's
largest developer and owner of utility -
scale solar energy projects, is proud to announce its landmark partnership agreement with COP21, the UN Framework Convention
on Climate
Change, which delegations representing over 150 countries will attend in Paris for 12 days with the objective of reaching a universal agreement
on how to slow the rise of global
temperatures.
Paleontological records indicate that global mean sea level is highly sensitive to
temperature (7) and that ice sheets, the most important contributors to
large - magnitude sea - level
change, can respond to warming
on century time
scales (8), while models suggest ice sheets require millennia to approach equilibrium (9).
A cold phase transition, which the historical record indicates can occur quite rapidly with
large secular
temperature changes on a decadal time
scale, would truly be a catastrophe.
Current computer models can faithfully simulate many of the important aspects of the global climate system, such as
changes in global average
temperature over many decades; the march of the seasons
on large spatial
scales; and how the climate responds to
large -
scale forcing, like a
large volcanic eruption.
This conclusion has subsequently been supported by an array of evidence that includes both additional
large -
scale surface
temperature reconstructions and pronounced
changes in a variety of local proxy indicators, such as melting
on icecaps and the retreat of glaciers around the world, which in many cases appear to be unprecedented during at least the last 2000 years.
It seems likely that the
temperature of the oceans is only
changed significantly as a result of events
on a very
large astronomic or geological
scale.
December 2015 is the deadline for a global commitment that will bind the world and set it
on the path to limit the
temperature rise to 3.6 degrees Fahrenheit (2 degrees C) in order to stop the dire,
large scale human and environmental cost of doing nothing, according to the United Nations Framework Convention
on Climate
Change (UNFCCC).
