Since
the beginning of the industrial age, the overall concentration
of CO2 has increased from 280 parts per million (ppm)
to
370 parts per million (ppm). Earths normal atmospheric level
of: Carbon Dioxide (CO2) is just 0.04%.
CO2
has increased by about 25% over the last 50 years, about 0.01% of the total volume of global CO2.
50% (0.005%)
of
the total volume of extra CO2 has already been absorbed
by the Oceans of the world.
Scientific
studies indicate that CO2 is one of several gases
that trap heat near the surface of the earth. Some scientists
have concluded that increases in the abundance of CO2
will generate an increase in the globally averaged temperature
of earth's atmosphere.
Current
research indicates that the anticipated changes that might
result from an increase in atmospheric CO2 are a
very complicated challenge. Computer models include changes to ocean currents
and to the jet stream that cause many parts of the Earth to
Cool while other part of the world experience an average
yearly temperature increase.
Thus, a
more correct term for this "phenomenon" is
"climate change" not global warming. Even with
extensive measurements of CO2 emissions, the
processes that govern the carbon cycle are not very well
understood.
Human
activities continue to release a slowly increasing amount of
CO2 into the atmosphere. However, at the same time,
measurements of atmospheric CO2 vary massively from
year to year.
Without
a better understanding of these variations, scientists will
have difficulty predicting how the atmosphere will respond
currently and in the future.
                   
The
contiguous Total
Solar Irradiance
database extends from late 1978 to the present, covering more
than two sunspot cycles, and one solar magnetic activity
cycle. It is comprised of many good observations of seven
independent satellite experiments: Nimbus7/ERB, SMM/ACRIM1,
ERBS/ERBE, UARS/ ACRIM2, SOHO/VIRGO, ACRIMSAT/ ACRIM3 and
SORCE/TIM.
A
composite database combining these results using overlapping
in-flight comparisons has begun to provide useful information
for both solar physics and climate change investigations.
More
attention from decision makers is imperative to
accommodate climate trends that are already underway.

The
characteristics and variability of the radiation emitted by
the Sun are of overriding importance to all life on Earth. The
Earth’s weather and climate regime is determined by the Total
Solar Irradiance
and its interactions with the Earth’s
atmosphere, oceans and landmasses. Evidence from paleo-climate
data and the subtle long term variations of Total
Solar Irradiance
caused by periodic changes in the Earth's orbit (milankovich
cycles) demonstrate the dominance of Total
Solar Irradiance in
climate change on time scales between 20 years and 10,000
years. Total
Solar Irradiance
monitoring, cosmogenic isotope analyses and correlative
climate data indicate that variations of the Total
Solar Irradiance received by earth
has been the most significant climate change factor (natural
force) during the current inter-glacial period (i.e. last
10,000 years.). Phenomenological analyses of Total
Solar Irradiance
monitoring results during the past three decades, and Total
Solar Irradiance
proxies during the past 400 years and the records of surface
temperature show that Total
Solar Irradiance
variation has been the preeminent dominant force for climate
change during the current industrial era. The periodic
character of the Total
Solar Irradiance
record indicates that Solar effect on climate change will be
the most dominant and variable contributor to climate change
in the future.
Monitoring
Total
Solar Irradiance
variability is clearly the most important component of climate
change research, particularly in the context of understanding
the relative force of natural and anthropogenic processes. The
requirements for long-term, climate Total
Solar Irradiance
database can be inferred from a recent Research Council study
which concluded that gradual variations in solar luminosity of
as little as 0.25 % was the most likely effect that created
the "little ice age" that persisted in varying
degree from the 14th to the mid 19th
centuries. A century-long Total
Solar Irradiance
database will have to be calibrated by either precision
or accuracy to within a fraction of this value to be of any
real use in assessing the magnitude of solar heating. The
current Total
Solar Irradiance database
is shown above.

Recent
Intergovernmental Commission on Climate Change Reported the key
impacts that are probably inevitable for planet Earth are:
-
Sea
level rise of 1-2 feet in the next 100 yeras
-
Decreased
snowfall, winter floods, and severe droughts
-
Increase
in natural woodland fires, and species extinctions
-
Summer
heat waves of escalating duration and concentration
-
Loss of
arable land due to more flooding type erosion
-
Population
relocation to more temperate areas of the world
The
Pilgrims Publishing Initiative will target four major gaps in
existing knowledge, and will target areas for research like:
- quantification
of risks that communities and economic sectors face in the
wake of change and increased weather variability.
- identification
of how individuals (people) and industries - are likely
to adapt in the absence of government intervention.
- to
find specific strategies and activities that are likely to
call for a role for government to reduce long term habitat damage.
- find
a framework to help decision makers to understand the strategies
and activities we think are "must-have global options"
Initial
funding for the research will total nearly £14 million and be
provided by both private foundations and EU Governments. |
