It may seem surprising to people, but you can look at something like Mars, which has a very thin atmosphere, and you can look at something like Venus which we tend to think of
as sort of having this rather heavy, clouded atmosphere, which [is] hellishly
warm because of runaway greenhouse effect, and on both of those planets you are seeing this
phenomenon of the atmosphere leaking away, is actually what directly has led to those very different outcomes for those planets; the specifics of what happened
as the atmosphere started to go in each case [made] all the difference.
With an El Niño expected to develop late this summer or in the fall, there is a chance that 2014 could move into the spot

A global
warming phenomenon in our spaceship is one of several unintended effects of the unregulated, swift increase of 1) absolute global human population numbers, 2) per capita consumption of limited resources, and 3) large - scale business activities that could be occurring synergistically and approaching a point in history when it will not be possible for the Earth's resource base and frangible ecosystems services to sustain life
as we now know it to be.
This is the linchpin: if the difference between pre-industrial and modern temperatures is not

The paper was accompanied by a press release entitled «Global

When I speak about climate science, communication and policy, I often use some variant of this visual aid to help separate a few important subcomponents of the

as global
warming:
Re 9 wili — I know of a paper suggesting,
as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any
warming (aside from greenhouse feedbacks) and more so with a
warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer
phenomenon (when it would be
warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

Roger disputed that carbon (
as CO2) caused any
warming, that honest, unaltered science thought CO2 to be the consequence rather than the driver of temperature increases, that increasing CO2 in the air was sourced by natural
phenomena rather than mostly man - made, and that to decrease CO2 to levels required by regulation would start to starve plants, making more folks on the planet to starve accordingly.
Just to rephrase my last question: If the current global
warming situation is man made, and / or caused by other natural Earthly factors, then why is every planet in our solar system experiencing this
phenomenon as well?
But when we really look at history objectively and tease out measurement problems and cyclical
phenomena, we are going to find that this trend is entirely consistent with a zero to negative feedback assumption for the climate
as a whole, meaning that man's CO2 is driving 1.2 C or less of
warming per doubling of CO2 concentrations.

; what leads you to believe that the physical and biological trends we've seen / measured are likely to reverse within a mere 20 years, especially if /
as we enter a solar upswing; how have you accounted for
warming - driven methane release; what credible peer reviewed literature on «the other side» are you describing; what supports your confidence that there is little to no probability that the AGW that you do accept will change weather patterns enough to disrupt crop planting / growing / harvesting / production severely (or do you classify famine
as a natural
phenomenon?)?
