That is roughly twice as much as scientists previously thought and three times
the overall rate of global warming, making central West Antarctica one of the fastest - warming regions on earth.

By comparing the small oscillations in cosmic ray
rate and temperature with the
overall trends in both since 1955, Sloan and Wolfendale found that less than 14 percent
of the
global warming seen during this period could have been caused by solar activity.
Brazil, for example, has reduced its deforestation - related emissions by two - thirds in just six years, and Indonesia, a large emitter
of global warming pollution because
of high
rates of deforestation, has pledged to cut
overall emissions by more than 25 percent by 2020.
This is based on the high correlation (r = 0.88)
of the observed
Global Mean Temperature Anomaly (GMTA) to be represented by cyclic global mean temperature pattern with an overall linear warming rate of 0.6 deg C per century as shown
Global Mean Temperature Anomaly (GMTA) to be represented by cyclic
global mean temperature pattern with an overall linear warming rate of 0.6 deg C per century as shown
global mean temperature pattern with an
overall linear
warming rate of 0.6 deg C per century as shown below:
While
global temperatures have been going up
overall, the
rate of warming varies.
There are two primary externalities that result from our emissions
of carbon dioxide into the atmosphere — 1) an enhancement
of the greenhouse effect, which results in an alteration
of the energy flow in the earth's climate and a general tendency to
warm the
global average surface temperature, and 2) an enhancement
of the
rate of photosynthesis in plants and a general tendency to result in more efficient growth and an
overall healthier condition
of vegetation (including crops).
The results here reveal a larger picture — that the western tropical Indian Ocean has been
warming for more than a century, at a
rate faster than any other region
of the tropical oceans, and turns out to be the largest contributor to the
overall trend in the
global mean sea surface temperature (SST)»
Note that regional proxies, such as the oxygen - isotope temperature reconstructions from the Greenland Ice Core Project that record Dansgaard - Oeschger events, often indicate faster regional
rates of climate change than the
overall global average for glacial - interglacial transitions, just as today
warming is more pronounced in Arctic regions than in equatorial regions (Barnosky et al., 2003; Diffenbaugh and Field, 2013).
Since the ocean surface
warms overall at about only half the
rate of the land surface (due to the larger thermal inertia), it is to be expected that the lower troposphere wouldn't
warm as fast as the
global surface average.

global warming, etc.) Other Any additional characteristic (e.g., soil organism toxicity, WGK water classification, etc.) relevant to the
overall evaluation but not included in the previous criteria 1.3.3 Material Class Criteria The following material classes are flagged due to the concern that at some point in their life cycle they may have negative impacts on human and environmental health.
