climate of
high unemployment and stumbling recovery, the GOP officials said.
But «let's try not to make it so» is also a good idea, if those who do want a consensus to address
climate change could challenge that trend: David Cameron has done so in making it a
high profile issue and taking a clear line - but he has tended to tell us that this proves his party has changed, which means he underestimates how far he seems to be from convincing a
rather large chunk of it.
That's why we have to look at the balance in terms of what is cheaper: Can we reduce emissions of greenhouse gases today so that we can stabilize the earth's
climate,
rather than adapt to the impacts of
climate change and incur much
higher costs over a period of time?
«We need a planning process that is equal to the scale and complexity of the challenge,
rather than continuing to depend on piecemeal efforts that put wildlife species and human communities at

highest clouds would get even
higher.
Rather, their analysis shows that if you compare the LGM land cooling with the model land cooling, then the model that fits the land best has much

climate.
(in general, whether for future projections or historical reconstructions or estimates of

higher or lower estimates than seen with a single approach.
I like this little dig at the denier - sceptic - contrarians who appear to be tree ring obsessed: «It is intriguing to note that the removal of tree - ring data from the proxy dataset yields less,
rather than greater, peak cooling during the 16th — 19th centuries for both CPS and EIV methods... contradicting the claim... that tree - ring data are prone to yielding a warm - biased «Little Ice Age» relative to reconstructions using other
high - resolution
climate proxy indicators.»
Thus, would you
rather have some of your money going toward the makers of
high - efficiency vehicles, many (or at least some) of which should be in the U.S., helping to create or preserve jobs in the U.S, by making these shifts, and all - the - while helping to reduce carbon dioxide emissions and protect the
climate; OR would you
rather continue to have much more of your money going to ExxonMobil and to overseas providers of oil, all - the - while continuing to pour larger amounts of carbon dioxide into the atmosphere?
At World
Climate Report, we believe, that instead of having an equal likelihood of occurrence, that the temperature rise during the next 50 to 100 years will lie closer to the low end of the IPCC projected range than to the
high end of the range and thus the overall impacts will tend towards the modest
rather than the extreme.
Finally, Montford asks the question as to why the scientists and the IPCC promoted the hockey stick at such a
high confidence level so prematurely, and why such extraordinary efforts were made to defend it when it arguably isn't a critical piece of the
climate puzzle,
rather than to learn from outside statisticians and do a credible error analysis on the data and the inferences.
In today's
high - tech
climate though, technology should be considered as a potential mechanism to foster curiosity and enhance engagement with the natural world,
rather than an adversary with which nature must compete.
If
climate senstivity to CO2 is eventually shown (
rather than just assumed) to be close to the sensitivity to solar, I think a case can then be made that the GHG attribution should be equal or
higher than the solar attribution, despite the large uncertainty in our knowledge of the increase in solar forcing.
«Thus, if
climate change effects are anticipated, or detected in basin - wide storm statistics, sensible policy decisions should depend on the projected overall shift in the probability of damage
rather than on a
high - threshold criterion for trend emergence.»

I myself am
rather curious about just exactly what will happen to clouds in a
high - CO2 world, since this would help resolve some of the mysteries of the Cretaceous
climate.
What's new is that several recent papers have offered best estimates for
climate sensitivity that are below four degrees Fahrenheit,
rather than the previous best estimate of just above five degrees, and they have also suggested that the
highest estimates are pretty implausible.
... we strongly support Delworth and Knutson's (2000) contention that this
high - latitude warming event represents primarily natural variability within the
climate system,
rather than being caused primarily by external forcings, whether solar forcing alone (Thejll and Lassen, 2000) or a combination of increasing solar irradiance, increasing anthropogenic trace gases, and decreasing volcanic aerosols.
The period between was a period where oscillation of
Climate was observed as variation of (much
higher) sea levels
rather than recurring glaciation events, for well over 200 Million years until the last ~ 3 Million.
Thus (for example) goals to enhance economic growth and reduce poverty should sit alongside environmental considerations in any research funding strategy, and as I've noted emphasis should be given to reducing the uncertainty
rather than simply projecting the extremes of it forward for little useful purpose (a
high volume of current research in
climate science).
Finally, we have not yet taken note here of Shindell»14 «Inhomogeneous forcing and transient
climate sensitivity» which makes a very strong case not only for the unexpected aerosol loading from China being the culprit for the divergence, but also, unfortunately, for the case that a
rather high sensitivity is a logical consequence of that explanation.

higher.
The lack of an increase in the rate of warming is therefore a major obstacle for a
high sensitivity to CO2, and strongly supports the view that
Climate Sensitivity to CO2 (if any at all) must be
rather low.
High mountain areas in that region experience a
rather different
climate.
This means that: 1) the annular modes vary on timescales as fast as weeks; and 2) the
high and low index polarities of the annular modes do not reflect two distinct states of the
climate system, but
rather the wings of a normally distributed frequency distribution.
For this reason, a joint research project between Widener University Commonwealth Law School and the University of Auckland recommended in Paris that national
climate commitments be stated in tons of emissions over a specific period
rather than percent reductions by a given date because waiting to the end of specific period to achieve percent reductions will cause the total tons of ghg emitted to be
higher than if reductions are made earlier.
I won't repeat what I said on an earlier forum, but a quick look at Paul Williams» presentation on numerical errors in
climate modeling shows a host of issues that would lead me to assign a
rather high uncertainty to the model results, and then we have the uncertainties in the physical models themselves.
Meanwhile, the few studies that involve a
higher spatial resolution generally do so by sacrificing the temporal coverage of the data, providing them with a «case study» point of view of a particular weather event,
rather than robust statistics required for an understanding of
climate.
The benchmarking of RE statistics was an issue that was put into play in McIntyre and McKitrick 2005a, where we observed that you could get
high RE statistics from pseudoproxies with autocorrelation coefficients mimicking the autocorrelation coefficients of actual proxies,
rather than the very low - order AR1 coefficients assumed (without proof) by
climate scientists.
Rather, we propose the possible development of a «warm LIA»
climate scenario for the coming century that combines

Rather than
climate change there is a far greater causal connection between the global warming alarmism of the Left and a moribund economy, staggeringly
high real unemployment, and the Left's war on everyone and everything from William Gray, George Bush, Gov. Palin to oil companies, hamburgers, big Cokes and the Tea Party.
I don't live in a cold
climate and don't have direct experience with this, but if you talk to people in the really cold places, like IECC
climate zones 6 and
higher, they'll say you have to use a heat recovery ventilator
rather than an energy recovery ventilator.
A year later, there has been some
rather spectacular unraveling of the
climate change juggernaut, although the
high priests of the IPCC don't quite realize it yet: the positive feedback at work, but in the opposite direction.

rather it was set in the year 1982: World Meteorological Organization verifies
highest temperatures for Antarctic region ASU
climate expert, WMO rapporteur talks about -LSB-...]
The point is not what has happened but what will happen, and it is not controversial to say that increased incidence and severity of heat waves will create more crop failures in direct proportion with their increased incidence and severity (
climate change bulls will claim offsets to cold snaps at
higher latitudes
rather than debate this point).
He was interested in knowing about anything which might help discover the identity of the Climategate whistleblower, or as he referred to them «the hacker», and why «foia» might have chosen «the Talkshop» to place a link to the server where he had uploaded the FOIA2011.zip file
rather than another «

So the carbon cycle sensitivity to temperature should be more relevant than the
climate sensitivity to CO2... or maybe not after all, considering that the ppm / C ratio around 280 ppm seems to be an order of magnitude
higher when CO2 is a forcing
rather than a feedback.
