(As an aside, remember that AGW supporters write off the Medieval
Warm Period because it was merely a local phenomena in the Northern Hemisphere not observed in the south — can't we apply the same logic to the late 20th century based on this satellite data?)
It was like the need to eliminate the Medieval
Warm Period because it showed the world was not warmer today than ever before.
Not exact matches
It doesn't heat the bottle from cold as well as I thought it did but that's ok
because it will keep it
warm for long
periods of time if preheated.
Because some global temperature records only begin in 1880, the
period 1880 to 1899 is the easiest «pre-industrial» baseline for measuring
warming.
Short - lived climate pollutants are so called
because even though they
warm the planet more efficiently than carbon dioxide, they only remain in the atmosphere for a
period of weeks to roughly a decade whereas carbon dioxide molecules remain in the atmosphere for a century or more.
For example, the polar bear specimen from roughly 120,000 years ago survived in Svalbard during a
warm interglacial
period because that Arctic archipelago remained more frozen than other areas.
«Unlike habitat generalists that can expand their distribution
because they do not have very specific habitat requirements, Sungazers likely do not even enter the process of producing sperm and eggs without the correct cooling and
warming periods that they experience seasonally in the wild,» says Parusnath.
«The thawing was probably very brief
because the layer deposited in the northernmost cave stalactite was relatively thin,» Vaks says — too thin in fact to determine how long the
warm period lasted.
This may have occurred
because the continents were clustered around the equator, and so a
warm Earth would be much more vulnerable to slight cooling trends that trigger a Snowball
period.
Second,
because the 1900 - 1950 TSI value was lower than the 1950 - 2000 TSI value, this would induce by alone a solar induced climate
warming of the atmosphere during 1950 - 2000 even if during the
period 1950 - 2000 the sun was perfectly constant.
There have not and will not always be ice ages
because the Earth can be just too
warm or ill - conditioned to respond in that manner (The Earth might also become too cold to have interglacials within an ice house
period — though I'm not sure if that has ever happenned outside the Proterozoic snowball / slushball episodes).
Hence, Earth - type life around flare stars may be unlikely
because their planets must be located very close to dim red dwarfs to be
warmed sufficiently by star light to have liquid water (between 0.02 and 0.05 AU for Wolf 424 A and B with an orbital
period in 3 and 12 days), which makes flares even more dangerous around such stars.
This animation shows how the same temperature data (green) that is used to determine the long - term global surface air
warming trend of 0.16 °C per decade (red) can be used inappropriately to «cherrypick» short time
periods that show a cooling trend simply
because the endpoints are carefully chosen and the trend is dominated by short - term noise in the data (blue steps).
Thus far, Kepler has found 48 planetary candidates in their host star's habitable zone (of which 10 are near Earth - size), but this number is a decrease from the 54 reported in February 2011 only
because the Kepler team is now applying a stricter definition of what constitutes a habitable zone around stars to account for the
warming effect of planetary atmospheres, which would move such a zone away from the star, outwards in orbital distance resulting in longer orbital
periods (NASA news release; and Kepler Press Conference slides — in pdf).
But the real function of the «
warm - up» isn't to
warm up per se, but actually to allow a
period for your body to slowly and gently move blood out of your organs and into your muscles without having to force blood out and in (respectively)
because it was surprised at the sudden onset of exercise.
I thought my
period reappeared
because my 13 year old daughter just had menarche and you know how two women living in the same house can affect each other... until I realized that since the
warmer months are here I stopped taking my vitamin D.
Static stretching done during
warm ups can increase flexibility for a short
period of time, but there are no studies that confirm that exercise performance is improved
because of it.
However, I can not complain,
because as many other cities are below the 70s or even 60s, LA still feels
warm, which extends the
period to wear skirts.
I live in North Jersey... However, the car I was looking for was in Philadelphia (about 130 miles away)... Loreal new this and called me the day I was... coming down... She wanted to let me know there was a scratch on the windshield... I was impressed with that
because, she was more concerned with me traveling over 250 miles (both ways) than making her sale... Regardless, when I arrived and met Loreal, she was informative, friendly and greeted me with a
warm friendly smile... What surprised me was this continued throughout the process... Loreal, was very accommodating and every concern I had, She guided me through this... I realize this is only the «honeymoon»
period of having this car....

Because they feed in Arctic and subarctic benthic environments, gray whales are thought to be relatively sensitive to changes in climate, and climatic events such as the Medieval
Warm Period (ca. 900 — 1200 AD) or Little Ice Age (ca. 1300 — 1850 AD) could have caused a population decline.
I think volcanic forcing is on a
warming trend,
because volcanic activity is weighted towards the beginning of the 30 year
period.
Higher levels of CO2 prior to 1940 had some role in
warming at that
period,
because of the greenhouse effect, but are insufficient when calculated to explain all the
warming.
«BTW, this graph also switches to 1880 - 1920 as a base
period,
because of the widespread interest in the magnitude of
warming relative to pre-industrial time.
«Dermot Antoniadesa said: «At this point, it doesn't appear that the shelf ice around Ellesmere Island is any smaller now than it was during the previous
period of
warming, but
because it's still shrinking, it's possible it could become, an «unprecedented» event.
We don't get to 100 % causation
because, over a long enough
period of
warming, we know there should be a needle in that haystack.
Because global
warming, in my home town now rarely have snow, chirdren have no the joy of our
period with snow.
I particularly enjoyed the slides that, when combined (1) provided an overview of hotter and cooler CO2 molecules as it relates to how they are seen from outer space and from profile —
because this will make it easier for me to explain this process to others; (2) walked through the volcanic and solar activity vs assigning importance to CO2 changes —
because this another way to help make it clearer, too, but in another way; (3) discussed CO2 induced
warming and ocean rise vs different choices we might make —
because this helps point out why every day's delay matters; and (4) showed Figure 1 from William Nordhaus» «Strategies for Control of Carbon Dioxide» and then super-imposed upon that the global mean temperature in colors showing pre-paper and post-paper
periods —
because this helps to show just how far back it was possible to make reasoned projections without the aid of a more nuanced and modern understanding.
The problem with odds for the medieval
warm period, as you have described it, is not possible
because the
warming was localized, patchy over time, and not «extreme.»
That might well be called nature's global
warming because what happens during an interglacial
period is the Earth
warms up, the glaciers melt and life flourishes.
If the planet's climate were changing solely
because that's what planets do, evolve through different climatic
periods of
warming and cooling over millions of years, adverse consequences like the loss of coral reefs and the potential for disappearing Polar Bears would still be undeniably sad, but at least a little easier to swallow.
Because the long - term
warming trends are highly significant relative to our estimates of the magnitude of natural variability, the current decadal
period of stable global mean temperature does nothing to alter a fundamental conclusion from the AR4:
warming has unequivocally been observed and documented.
You just can not use the simplistic argument that
warmer air means more precipiation
because of more water vapor to explain a very cold, very wet
period.
The
warming period from about 1970 to currently has been over 90 % attributed to greenhouse gases,
because solar activity has been low over this
period.
If C02 is the largest single contributing factor to the Greenhouse Effect (
because supposedly water vapor is only involved as a feedback to primary chemistry involving C02 itself), and C02 lags temperature increases (as has been stated on this very blog), how has the Earth ever returned to colder glacial conditions following
periods of
warming?
The last timeframe in the Sub-polar Gyre was not published in Curry & Mauritzen's paper
because they had very little data from the western Sub-polar Gyre in that
period — the volume budget would therefore be biased towards the salty eastern atlantic, where the
warm, salty subtropical waters reside.
Re # 33 (Dave D.): Ice core measurement issues aside, remember that there has to be some degree of lag
because a) the initial
warming is from Milankovitch changes, not CO2, and 2) the delayed turnover of ocean water means that not all the CO2 will outgas in a short
period of time.
Decades within the base
period do not appear particularly
warm or cold
because they are the standard against which all decades are measured.
And explains why Earth
because it past much
warmer periods hasn't already had a runaway effect.
They also fail to appreciate that
because solar radiation was at a historic high during the
period in question it likely follows that there was a net solar
warming of the oceans throughout the
period even though the rate of solar radiation was on average stable during that
period.
Because without the HS, the Mideval
Warm period sticks out as a hughe problem.
No, the Bristlecone pines do matter,
because the claims about the level of the Medieval
Warm Period depend heavily on the Bristlecone pines (in nearly all of the studies — so far as I can tell) It's not unscientific to say so.
I don't want this to turn into a Medieval
Warming Period debate
because that has been done to death and is not very interesting.
I was rudely awakened byt the hockey stick fiasco,
because I knew that there existed a mediaval
warm period where Greenland was green.
The datasets produced by Cowtan and Way (2013) do not appear to provide polar amplification for the
period of 1979 to 2004,
because the HADCRUT4 data
warmed faster than the Cowtan and Way (2013) data before 2005.
And
because the ocean surface doesn't
warm very much during this
period, the atmosphere doesn't
warm as much either.
Both Judith Curry and Gavin Schmidt have acknowledged that even if Trenberth is right about global
warming being sequestered in the deep ocean it doesn't matter
because that sequestered heat can not undilute itself to
warm the atmosphere quickly — it comes out over a 10x longer
period at 1 / 10th the orginal power i.e. what when in at 0.5 W / m2 in a decade comes out at 0.05 W / m2 over a century which is insignificant.
The size of the imbalance varies with the time span you consider,
because it is larger in
periods of weak surface
warming such as the last decade, when 0.9 W / m2 pertains, but smaller over longer
periods that have more
warming at the surface such as the last 20 - 30 years.
This modern

Because of methane's greater greenhouse potency, the
warming potential of the emissions measured during the second
period greatly exceeded the potential cooling produced by the uptake of carbon dioxide during photosynthesis.
