Not exact matches
The process also creates tiny bits of soot, called black carbon, and traces of harmful substances, known as brown carbon, which together cause more global
warming per unit weight
than other human - associated carbon
sources.
I know some here will decry that I am not talking about the issues because I do not try to obsfuscate with a discussion of the spot market price of coal vs long - term contracts, or use of coal in locations
other than Kansas, or Al Gore's footprint, but the issue of Global
Warming IS politics (non-ratification of Kyoto and negative flag - waving ads about politicians who oppose coal), it IS public relations («Clean Coal», cleanest coal - fired plants, surface mining and mountain - top reoval rather
than strip mining, etc.), and it IS about misrepresentation (Peobody framing the debate as coal vs NG when it is really coal vs every
other energy
source), and it IS about greed (the coal industry doing everything it can to scuttle every
other energy alternative).
This is your hardest question to answer, as the question seems to presuppose their are
other sources of heat that are
warming up the earth
other than global
warming due to CO2, methane, nitrous oxide (from agriculture and fertilisers) and CFCs (chlorofluorocarbons, from refrigerants etc) accumulating in the atmosphere from mankind's various activities.

Others have identified the lags in the southern ocean (which
warms more slowly
than the northern hemisphere, and northern land in particular) as the
source of this time dependence of feedbacks, and we've demonstrated that different forcings have subtly different impacts — `
This shift away from CO2 - centric emissions debates is also evident in a group blog post by analysts at the Center for American Progress, who propose a «multiple multilateralism» approach on climate that, among
other things, seeks quick steps on
sources of
warming other than carbon dioxide — particularly sooty Arctic pollution and gases already considered under the existing ozone - protection treaty.
Others have identified the lags in the southern ocean (which
warms more slowly
than the northern hemisphere, and northern land in particular) as the
source of this time dependence of feedbacks, and we've demonstrated that different forcings have subtly different impacts — to some extent based on their spatial signatures.
Generally, the remaining uncorrected effect from urban heat islands is now believed to be less
than 0.1 C, and in some parts of the world it may be more
than fully compensated for by
other changes in measurement methods.4 Nevertheless, this remains an important
source of uncertainty.The
warming trend observed over the past century is too large to be easily dismissed as a consequence of measurement errors.
The Great Global
Warming Swindle and every
other skeptical
source that shows you this graph and claims it shows that the MWP was
warmer than today is not giving you the full picture.
This is because over the past three years, hundreds of new scientific field accounts of global
warming's impacts, as well as improved peer - reviewed analyses of global
warming itself in both the deep past and the very near future, have depicted earth's atmosphere as far more «sensitive» to the invisible CO2, methane and
other human -
sourced greenhouse gases
than had been hoped.
The physical evidence for man - made global
warming has never been demonstrated - evidence that many of us trained in the sciences have been waiting.When some scientists suggest that
other forces
other than man - made CO2 may be involved with the climate, like the Sun, the clouds, the oceans, natural
sources of CO2, etc., they are met with scorn and derision.
Aircraft not only emit 12 percent of CO2 emissions from U.S. transportation
sources — they also emit nitrogen oxides
other than nitrous oxide, causing
warming when emitted at high elevation.
More recently, scientists have been surprised to learn that black carbon — not only from biomass fires but from dirty diesel engines and
other sources — is a far larger contributor to global
warming than previously suspected: The dark particles absorb and retain heat close to the Earth's surface that might otherwise be reflected.
> The Daily Mail has given more
than five times as much space to the Global
Warming Policy Foundation's views in its recent coverage of climate change and «green taxes»
than to any
other source.
Many — perhaps most — won't know that the Daily Mail gives so very much more space to the Global
Warming Policy Foundation
than to any
other source on climate / clean energy cost stories.
The Mail gives 5 times more space to the Global
Warming Policy Foundation

The phrase «there is no need of heat to «
warm the surface» «does seem to imply a
source of heat
other than solar radiation, and the author immediately goes on to mention gravitation.
That said,
other than an increase in solar intensity (the sole
source of energy in)- which has not happened as it has in fact been the opposite recently, none of the internal variability factors that affect global temperature could have produced the monotonic
warming over 35 years that we have observed.
He also explains that a large number of data
sources,
other than the temperature record, show that the world is
warming.
E.g., research assumes greenhouse gas emissions cause
warming without explicitly stating humans are the cause»... carbon sequestration in soil is important for mitigating global climate change» (4a) No position Does not address or mention the cause of global
warming (4b) Uncertain Expresses position that human's role on recent global
warming is uncertain / undefined «While the extent of human - induced global
warming is inconclusive...» (5) Implicit rejection Implies humans have had a minimal impact on global
warming without saying so explicitly E.g., proposing a natural mechanism is the main cause of global
warming»... anywhere from a major portion to all of the
warming of the 20th century could plausibly result from natural causes according to these results» (6) Explicit rejection without quantification Explicitly minimizes or rejects that humans are causing global
warming»... the global temperature record provides little support for the catastrophic view of the greenhouse effect» (7) Explicit rejection with quantification Explicitly states that humans are causing less
than half of global
warming «The human contribution to the CO2 content in the atmosphere and the increase in temperature is negligible in comparison with
other sources of carbon dioxide emission»»
That's the finding of a new Harvard study that, for the first time, examines the true cost of coal throughout its entire life cycle... Clearly, the fact that coal contributes more global
warming pollution
than any
other source in the nation is far from its only problem.
Other surprises include the recognition that reducing methane emissions from whatever source has important indirect impacts on a range of other drivers and is a more effective strategy for short - term reductions in global warming than had been previously recogn
