In other words, with more nitrogen available, plant life might be able to absorb more
CO2 than climate scientists have been estimating, which means the planet won't warm as much, despite mankind's pumping CO2 into the atmosphere.

Not exact matches
No one yet knows the extent to which methane and NF3 will impact global temperatures, but NASA
climate scientist Ralph Kahn says one thing is certain: «We know it's more
than just
CO2 that matters.»
But now we've got significantly more
CO2 in the atmosphere
than there was even during the warm periods, and
climate scientists have some hints that we're actually at the highest levels in perhaps 15 million years.
I'm not even an amateur
climate scientist, but my logic tells me that if clouds have a stronger negative feedback in the Arctic, and I know (from news) the Arctic is warming faster
than other areas, then it seems «forcing GHGs» (
CO2, etc) may have a strong sensitivity
than suggested, but this is suppressed by the cloud effect.
Where do you believe that Dr. Curry implies agreement that leading
climate scientists are incompetent and should not be working, and that there is a cover - up and that the current warming is caused by an iron sun rather
than increased
CO2 from human activity?
However, because
climate scientists at the time believed a doubling of atmospheric
CO2 would cause a larger global heat imbalance
than today's estimates, the actual
climate sensitivities were approximatly 18 % lower (for example, the «Best» model sensitivity was actually closer to 2.1 °C for doubled
CO2).
However, as in the FAR, because
climate scientists at the time believed a doubling of atmospheric
CO2 would cause a larger global heat imbalance
than current estimates, the actual «best estimate» model sensitivity was closer to 2.1 °C for doubled
CO2.
«So, imagine you are a
climate scientist and
climate change ideologue, and want to «take down» the single organization (or individual) that is doing the most damage to the movement (i.e. with the end result of thwarting
CO2 emissions / stabilization policy)» And why would you ever imagine that this activity was as or more important
than working on evidence supporting your position?
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.
We can find
climate scientists who give lower estimates of
climate's sensitivity to
CO2 whose arguments are better grounded in science
than any number of eco-warriors whose arguments are irrational, emotional, and lack any sense of proportion.
The probability distributions give a most likely estimate of 3 °C of warming for a doubling of
CO2, and all pragmatic
scientists tend to work on the basis that the
climate sensitivity is not drastically more
than that.
Climate skeptic
scientists have long questioned whether the effects of relatively minor (compared to other
CO2 sources and sinks) human - caused emissions of
CO2 have more
than a minor effect on global temperatures and some have even questioned whether the UN and USEPA have even gotten the causation backwards (i.e., because on balance global temperatures affect atmospheric
CO2 levels).
I can't think of anything better
than this to test the hypothesis of
climate scientists, the notorious ones and others as well, that CAWG can't be due to anything other
than CO2 because we can't think of anything else that could cause it.
Idso told the audience that we «should let
CO2 rise unrestricted, without government intervention», a very different recommendation
than that emanating from the IPCC and the vast majority of the world's
climate scientists.
But another development over the last 30 years is that the
climate industry,
scientists and modelers alike, have become ever more certain that
CO2 is the driver of
climate, and that «it's worse
than we thought.»
You're not a
climate scientist, but how can you even play one on TV without knowing that methane is a much more powerful GHG
than CO2?
Several
climate scientists will attribute more
than 100 % of the warming to
CO2 — they can due this if the man - made reflective aerosols and ozone are canceling out a portion of the
CO2 influence.
However, because
climate scientists at the time believed a doubling of atmospheric
CO2 would cause a larger global heat imbalance
than is currently believed, the actual
climate sensitivities were approximatly 18 % lower (for example, the «Best» model sensitivity was actually closer to 2.1 °C for doubled
CO2).
After suggesting
Climate Scientist Myles Allen presented a misleading graph about CO2, and after receiving an admission from Oceanographer Gary Griggs that ice ages and other violent climate shifts, far greater than today's mild warming, can be caused by natural forcings, Judge Alsup turned to the centrepiece of the conspiracy charge, the «Smoking Gun»

than today's mild warming, can be caused by natural forcings, Judge Alsup turned to the centrepiece of the conspiracy charge, the «Smoking Gun» memo.
There certainly have been times in the past when the Earth was warmer
than it is now, but
climate scientists project that we're only at the start of a warming response to the
CO2 that's already in the air (not to mention all the additional
CO2 that will be going into the air in years to come.)
As the former NASA
scientist Jim Hansen recently told Rolling Stone: «We are at the point now where if you want to stabilize the Earth's energy balance, which is nominally what you would need to do to stabilize
climate, you would need to reduce emissions several percent a year, and you would need to suck 100 gigatons of
CO2 out of the atmosphere, which is more
than you could get from reforestation and improved agricultural practices.»
While carbon dioxide receives most of the attention in the debate over greenhouse gas emissions,
climate scientists warn that methane is about 30 times more potent
than CO2 in terms of contributing to a warmer
climate.
These
scientists have found that, in the absence of any significant
CO2 concentration changes or human influence during the Holocene (i.e., the last ~ 10,000 years), the deep oceans naturally warmed by more
than 2 °C in a span of just 200 years, which is several times the rate in which they are alleged to have warmed in the last ~ 60 years of the supposedly dominant anthropogenic influence on
climate.
Never - the-less, it is generally accepted by most all
climate scientists that, in the absence of feedbacks, future increases in atmospheric
CO2 will have less effect on world temperature
than past increases, and that there is a cap (in this chart around 1.5 degrees C) on the total potential warming.
Of course, I am even more convinced today
than I was (after reviewing IPCC SPM 2007) 3 years ago (especially after all the recent revelations of shenanigans and «junk science» by the
scientists and bureaucrats involved with IPCC) a) that humans are not destroying our planet with
CO2 emissions and b) that we do not have the ability to make changes in our
climate by reducing these emissions.
