second collection of papers confirm that (b) natural ocean oscillations are,
in turn, modulated by solar activity.
Second, we examined the
change in frequency of occurrence of unusually hot, dry or windy conditions by comparing the number of years that maximum
temperature, rain - free days or wind speed was > 1 s.d. above the mean or when minimum relative humidity was < 1 s.d. from the mean
in 1996 — 2013, as compared with the number of similar events observed
in 1979 — 1996.

There are two very basic answers: First, looking at
changes in data gets rid of biases at individual stations that don't
change in time (such as station location), and
second, for surface
temperatures at least, the correlation scale for anomalies is much larger (100's km) than for absolute
temperatures.
There is no evidence that anything unusual happened from the added CO2
in the
second half of the 20th century... and the average
temperature has barely
changed so far
in the 21st century, especially if you ignore the 2015 / 2016 El Nino peak, which has nothing to do with CO2.
The
second example follows a few other papers
in challenging the assumptions behind constraints on the Charney sensitivity derived from historical
changes in temperature and forcings.
The
second aspect of climate
change that is likely affecting Alaska more and more is the apparent tendency of warming
in the Arctic and warmer sea surface
temperatures in the Pacific to contribute to larger waves
in the jet stream.
The
second study meanwhile looked at how aerosol emissions impact the Earth's
temperature through a phenomenon the researchers call «transient climate sensitivity,» or how much of the Earth's
temperature will
change when the amount of carbon dioxide
in the atmosphere reaches twice its level during the pre-industrial times.
The trend
in rising average
temperatures in Australia
in the
second half of the 20th century is likely to have been largely caused by human - induced climate

Mr. Dickson wrote passionately about several areas
in climate science that troubled him, including: first, the idea that 97 percent of climate scientists agree that climate
change is real, caused by humans, and a threat;
second, the idea that government agencies had manipulated
temperature records to fit a narrative of warming; and third, that China is developing its coal resources so fast that nothing short of radical population control will save us, if burning fossil fuels really does cause global warming.
The mainstream explanation would be that the steep
temperature gradient 1880 - 1960 was due to a combination of (slowly
changing) solar and aerosol variation, but that there was little net solar heating from TSI
changes in the
second half of the 20th century.
The
temperature profile
in the
second half of the year
changed in 2013 and 2014, that stalled the process of decline.
Leaf area index, which is also enhanced by increasing atmospheric carbon dioxide, was the
second most important factor, contributing an additional 21.8 percent, followed by climate
change (precipitation and air
temperature together) and the fraction of photosynthetically active radiation, which accounted for the remaining 18.3 and 14.6 percent increase
in NPP, respectively.
Second, there has been a historical
change in how ships measure surface
temperatures.
Second, their
temperature reconstructions were not based exclusively on TSI
changes as the sole source of
temperature variation, but included associated
changes in spectral irradiance that would be expected to amplify TSI effects,
changes in UV being one example.
The
second question asked: «Do you think human activity is a significant contributing factor
in changing mean global
temperatures?»
Watching the current hurricane coverage (family
in Fla / Ga / NC) I see no mention of sea surface
temperature, no graphics of how it's
changing as the hurricane tracks across it, nothing about the
second hurricane coming on soon.

The
second and more interesting (to me) observation is that the simulated
temperature changes are punctuated by multiple short term peaks and dips, differing from one model run to another, although the climate variables mentioned above were omitted from the simulations — there were no
changes in model input
in solar or aerosol forcing, and ENSO was largely eliminated by smoothing.
Figure 3: Example of how the average global surface
temperature would have had to
change in the
second half and third quarter of the year for McLean's 2011
temperature prediction to become accurate.
The next is the nature of the distribution of the values for the first difference (monthly
change in temperature,
second row).
There was a report issued by the World Meteorological Organisation (WMO)
in 1997 entitled «Instruments and Observing Methods» (Report No. 65) that explained because the modern electronic probes being installed across Australia reacted more quickly to
second by
second temperature changes, measurements from these devices need to be averaged over a one to ten - minute period to provide some measure of comparability with the original thermometers.
Then look at the
second differences (acceleration of monthly
change in temperature, third row).
Smith, who is the convening lead author of the
second working group report on vulnerability to climate
change, says: «The new assessment has increased our confidence that the effects for climate
change are beginning to be seen,
in terms of rise
in temperature, sea levels and heavy precipitation events».
This captivating video created by Antti Lipponen visualizes more than 100 years of
temperature change in 191 countries
in just 35
seconds.
Minnett measured around 0.5 K
temperature difference between max and min DLR (about 100W
change) and so this equilibrium would be reached
in about 0.25
Seconds
The
second question is, postulating that the
temperature record from satellites is absolutely accurate and unfudged, and
in light of the fact that climate
changes historically occur naturally with periods of hundreds to thousands of years, do you think that the 31 annual data points available from the satellite record are adequate to establish long term climate trends and that the trends are a consequence of human activity?
In the absence of any other change in heat flow (an unphysical assumption but let's use this as a thought experiment), instead this increases the temperature by (initially) 100/42 = 2.4 K per secon

The Daily Mail (
second highest selling newspaper
in the UK) today says: «American «climate
change experts» have been exposed for fiddling
temperature records to make it appear the past was colder than it actually was.»
It also shows that there is a step
in the relationship, probably caused by either
temperature, anthropogenic
changes to the biotic capacity or more likely that the efflux of CO2 from the atmosphere is of an order greater than 1 (i.e. has a first - order and
second - order reactions).
The first of these concerns the terrestrial and oceanic processes that release greenhouse gases into the atmosphere and then absorb them, and the
second is a calculation about what a
change in carbon dioxide levels really means for average global
temperatures.
In their study, Meehl et al. show that natural forcings can not account for the increase in global temperatures in the second half of the 20th century, and that models using both natural and anthropogenic forcings model the temperature change over the 20th century most accuratel

Here, we present an explanation for time - invariant land — sea warming ratio that applies if three conditions on radiative forcing are met: first, spatial variations
in the climate forcing must be sufficiently small that the lower free troposphere warms evenly over land and ocean;
second, the
temperature response must not be large enough to
change the global circulation to zeroth order; third, the
temperature response must not be large enough to modify the boundary layer amplification mechanisms that contribute to making φ exceed unity.
Our ability to place the recent
temperature increase
in a longer paleoclimate perspective is also hampered by an apparent
change in the sensitivity of recent tree - growth to
temperature at high northern latitudes where trends
in TRW and MXD have been reported to increasingly diverge from the instrumental records during the
second half of the twentieth century (Jacoby and D'Arrigo 1995; Briffa et al. 1998a, b; D'Arrigo et al. 2007).
The
second,
in Geophysical Research Letters (August 30th) provides the first statistical reconstruction of Antarctic
temperature change, extending about 200 years into the past.
The
second line of evidence arises from indirect, historical estimates of past climate
changes that suggest that the
changes in global surface
temperature over the last several decades are unusual (Karl et al, 2009).
The
second thing is that when you do look
in detail at the data and use the appropriate approach you find you need to be looking not at the raw data, but at the time series made up of the difference between each pair of consecutive
temperatures i.e. the
change in temperature.
It went something like this: hotel check -
in, locate room, locate wifi service, attempt connection to wifi, wonder why the connection is taking so long, try again, locate phone, call front desk, get told «the internet is broken for a while», decide to hot - spot the mobile phone because some emails really needed to be sent, go «la la la» about the roaming costs, locate iron, wonder why iron
temperature dial just spins around and around, swear as iron spews water instead of steam, find reading glasses, curse middle - aged need for reading glasses, realise iron
temperature dial is indecipherably
in Chinese, decide ironing front of shirt is good enough when wearing jacket, order room service lunch, start shower, realise can't read impossible small toiletry bottle labels, damply retrieve glasses from near iron and successfully avoid shampooing hair with body lotion,
change (into slightly damp shirt), retrieve glasses from shower, start teleconference, eat lunch, remember to mute phone, meet colleague
in lobby at 1 pm, continue teleconference, get
in taxi, endure 75 stop - start minutes to a inconveniently located client, watch unread emails climb over 150, continue to ignore roaming costs, regret tuna panini lunch choice as taxi warmth, stop - start juddering, jet - lag, guilt about unread emails and traffic fumes combine
in a very unpleasant way, stumble out of over-warm taxi and almost catch hypothermia while trying to locate a very small client office
in a very large anonymous business park, almost hug client with relief when they appear to escort us the last 50 metres, surprisingly have very positive client meeting (i.e. didn't throw up
in the meeting), almost catch hypothermia again waiting for taxi which despite having two functioning GPS devices can't locate us on a main road, understand why as within 30
seconds we are almost rendered unconscious by the
in - car exhaust fumes, discover that the taxi ride back to the CBD is even slower and more juddering at peak hour (and no, that was not a carbon monoxide induced hallucination), rescheduled the
second client from 5 pm to 5.30, to 6 pm and finally 6.30 pm, killed time by drafting this guest blog (possibly carbon monoxide induced), watch unread emails climb higher, exit taxi and inhale relatively fresher air from kamikaze motor scooters, enter office and grumpily work with client until 9 pm, decline client's gracious offer of expensive dinner, noting it is already midnight my time, observe client fail to correctly set office alarm and endure high decibel «warning, warning» sounds that are clearly designed to send security rushing... soon... any
second now... develop new form of nausea and headache from piercing, screeching, sounds - like - a-wailing-baby-please-please-make-it-stop-alarm, note the client is relishing the extra (free) time with us and is still talking about work, admire the client's ability to focus under extreme aural pressure, decide the client may be a little too work focussed, realise that I probably am too given I have just finished work at 9 pm... but then remember the 200 unread emails
in my inbox and decide I can resolve that incongruency later (
in a quieter space), become sure that there are only two possibilities — there are no security staff or they are deaf — while my colleague frantically tries to call someone who knows what to do, conclude after three calls that no - one does, and then finally someone finally does and... it stops.
