«We have concluded close to all of the recent trends in global
temperature is due to human activity, and CO2 is the dominant factor,» Schmidt said, referring to carbon dioxide.
11 Global and continental temperature change This observations confirms that the increasing of
temperature is due to the human activities.
Not exact matches
That may
be particularly important in a time of rapid change
due to rising ocean
temperatures and increasing
human activity on the high seas.
Global warming
is the rise in
temperatures caused by an increase in the levels of greenhouse gases
due to human activity.
Given that there
is continual heating of the planet, referred
to as radiative forcing, by accelerating increases of carbon dioxide (Figure 1) and other greenhouses
due to human activities, why
is the
temperature not continuing
to go up?
Therefore, IMHO, it would
be closer
to the truth
to call WUWT a «skeptic» site that calls into question exactly how much the mean
temperature has increased since the advent of the thermometer record in the late 1880's, how much of that
is due to human activities and how much
to natural cycles not under our control, what dangers rising
temperatures may pose
to human life and civilization, and what technologically and politically doable actions may
be taken
to reduce
human - caused warming, and our dependence on foreign sources of fossil energy.
The evidence that its increase
due to human activity is increasing the greenhouse effect
is far from conclusive, at worse perhaps 1/2 of
temperature rise in the past 20 years could
be due to CO2.
But even if you choose
to doubt them, it
is really the first seven that, combined, point
to human activities as the only explanation of rising global
temperatures since the Industrial Revolution, and the subsequent climate changes (such as ice melt and sea level rise) that have occurred
due to this global warming.
The accompanying abstract tells us it
's likely that a
temperature trend
is «partially
due to human activities, although many uncertainties remain...» (my emphasis).
The bottom right map shows results from models in which things like greenhouse gases, sea surface
temperatures, and sea ice
were allowed
to change as they have in the real world
due to human activities.
The rate at which the
temperature is rising took a huge leap starting a century ago, and it
's due to human activity.
95 % confidence that 50 % of the warming since 1951
is due to some form of
human activity is not likely
to be falsified using «Global» surface
temperature since about 30 % of the warming
is over land and GISS interprets high latitude and higher altitude warming as «surface» warming.
Not only
is their conclusion that global warming
is primarily
due to human activity, but also that
temperatures will increase significantly because of increases in anthropogenic atmospheric CO2.
In climate - change discussions, two Princeton professors go against the grain By Mark F. Bernstein The issue of climate change, or global warming, has become a rallying cry: The Earthâ $ ™
s surface
temperatures are Ârising
due to increased levels of carbon dioxide and other Âgreenhouse gases in the atmosphere, much of it produced by
human activity.
CO2 doesn't absorb in the infrared, increases in CO2 concentration aren't
due to human activity, increases in the CO2 partial pressure aren't increasing
temperature, increases in
temperature aren't likely
to be catastrophic?
There seems little doubt that this recent rise — this steep rise in
temperature —
is due to human activity.»
When the world
is cooling and ther
is negative correlation between CO2 and global
temperature and the IPCC declares «unequivocally concluded that our climate
is warming rapidly, and that we
are now at least 90 % certain that this
is mostly
due to human activities» one must conclude that there
is something terribly wrong with the IPCC!
El Niño makes
temperatures change from year
to year, but in the long run, the Earth
is steadily warming and it
's due to human activity.
This will
be done
to figure out how the changes in
temperature, as well as the added effects of climate change
due to human activity, affect moss growth in the long term.
Remember that this
is the same Professor who believes that ``... the Great Barrier Reef will benefit from rising seas, that there
is no correlation between carbon dioxide levels and
temperature, that only 0.1 % of carbon dioxide emissions
are due to human activities, and that 96 % of the greenhouse effect
is due to water vapour.»
Global
temperature is influenced by a number of factors, some natural and some
due to human activities.
(Its most recent report, in 2007, concluded that most of the twentieth - century increase in global average
temperatures was «very likely»
due to human activities, and that world
temperatures could rise between 1.1 and 6.4 °C during the twenty - first century.)
As far as rising ocean
temperatures are concerned, I know studies (like Barnett et al 2005) demonstrated there
is an anthropogenic signal (if I
am using the term correctly, meaning a discernable increase in ocean
temperature that
is due to human activities) globally.
CO2
is emitted
due to human activities, forcing the
temperature to rise.
In fact, they conclude that there
is a greater than 90 per cent chance that
temperatures are rising
due to human activities.
The only way we can explain that
temperature increase
is due [sic]
to human activity.»
