Just want to post some interesting links regarding the global temperature for 2020. To keep this thread civil and valid, PLEASE post a link backing up what ever info you are posting. No link, please find another thread to post in, there are plenty.
Both Satellite and terrestrial global temperature summaries are now available for the 2020 year. First to look at is here (please post links in this thread!) Roy Spencer, PhD This is the UAH global satellite data since 1979
From the link above
Quote:
2020 ended as the 2nd warmest year in the 42-year satellite tropospheric temperature record at +0.49 deg. C, behind the 2016 value of +0.53 deg. C.
Cooling in December was largest over land, with 1-month drop of 0.60 deg. C, which is the 6th largest drop out of 504 months. This is likely the result of the La Nina now in progress.
The linear warming trend since January, 1979 remains at +0.14 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).
The global temperature for 2020 was 0.88C equaling that in 2016 based on GHCN-V4C (homogenized) and HadSST3. The V4U (uncorrected) result is 0.82C for 2020 making it slightly cooler than 2016. These are based on the Spherical Triangulation technique
December saw a large drop in global temperatures relative to November mainly due to a strong La Nina developing in the South Pacific.
So 2020 will end up being the second warmest year on record likely because of a cooler La Nina developing late in the year.
(again, please post a reference to any info given such as on the storm or fire 2020 season to keep this civil and accurate.)
If you notice-- over the last century or so, for which we have fairly credible data, all the warming (and cooling) seems to occur in a year with a significant jump up (or down) followed by several years of steady temps....That's expected when the temps are related to the additive effects of several cyclic phenomena with different periods (review your old Trig notes)...and not explainable by attributing it to one isolated phenomenon (such as an El Nino or co2 levels).
Note that in the graph you posted, the baseline is the 30 yr average starting in '79-- the first year of the satellite record. Longer data sets show an obvious 60 yr cycle of warming & cooling, so we seem to be at the peak of the warming half of this cycle and would "expect" things to cool down again over the next 30 yrs....We did cool significantly over the last few months-- maybe helped by the effects of the summer forest fire season coupled with La Nina in addition to the "natural cycle."
No warming for almost 25 yrs now. [url]https://wattsupwiththat.com/2021/01/14/a-new-pause/[/url]

Really? A website by the name “wattsupwiththat†is your idea of credibility and reliability?
Hahahaaaahaa!!!!
You make me laugh so hard. You must make lots of money with your jokes.
Not a fan at all of wattsupwith but I have to give credit to GLM for posting a link.. Thanks for that.
FYI, there is marketing funded by the fossil fuel industry to deceive the voting public about climate change so lets examine wattsupwiththat.. (keeping with showing sources of info), from this web site https://mediabiasfactcheck.com/watts-up-with-that/
On the conspiracy theory level, wuwt rates "strong" but falls short of achieving "tin foil hat" status.
Wuwt scores "low" for factual reporting.
Quote:
Watts Up With That? (or WUWT) is a blog promoting climate change denial that was created by Anthony Watts in 2006? The blog predominantly discusses climate issues with a focus on anthropogenic climate change, generally supporting beliefs that are in opposition to the scientific consensus on climate change.
Watts's blog has been criticized for inaccuracy. The Guardian columnist George Monbiot described WUWT as "highly partisan and untrustworthy".[29] Leo Hickman, at The Guardian's Environment Blog, also criticized Watts's blog, stating that Watts "risks polluting his legitimate scepticism about the scientific processes and methodologies underpinning climate science with his accompanying politicised commentary."[30]
Now.. take a look at the first plot in the article linked..
Hmm... that plot is supposed to be the UAHv6 global mean temperature change from satellite data. For some "convenient reason", it only goes out to 2015..
Note how the wuwt hand picked some set of data (I assume they were not so crooked as to just make it up) but notice how different the wuwt plot looks compared to the actual plots from UAH. And the actual plots do not support that "not worth reading" article. I personally would not trust anything that comes out of wuwt.

No link posted for this (recycled idea.. how many times have I seen this already)... not even the single link that is now 9 years old based on hand picked distorted data.
Here is a very recent post on the Hadcrut5 terrestrial global warming (with a link showing exactly where the info comes from) http://clivebest.com/blog/?p=9852
Im not really seeing the 60 year cycle trend for cooling in the next 30 years... That looks way more like natural temperature variations for the first half of that plot but the second half temperature rise is is dominated by human caused sources such as a steady increase in CO2 level.
Some simple algebra-- (which you don;t really need to do had you read the article. They make their computation using data from 1996 (could've cherry picked by starting with '98 and shown cooling since then)--
---let's over-estimate and say all 5 yrs since '15 were 0.5* higher than the baseline in the UAH data set. Add them to get 2.5* total "degree yrs" above the average (0* warming) which runs from '96 -'15--- now divide the 2.5 by the 26 yrs to get a warming trend of 0.09*/yr-- a miniscule amount, well within the margin of observational error.
No warming since '96. QED. (while co2 levels have gone from 360 to 420 over that period of time.)
Your graphs continue to be illustrated disingenuously as I've said before-- they spread a minor 1* out over a 6 inch abscissa while cramming 160 yrs into a 6 in ordinate. We won't mention the insignificance of 1* of warming in a century where yearly variance is 120*....
....Have you sold your overcoat because the world is 1* warmer now than it was in 1920?
https://www.nsstc.uah.edu/climate/20...42yr_Trend.PNG Here's a break down of that UAH data '79-'20. Note that almost all of the warming has occurred in the N circum-polar region. Most of the globe is unchanged to minimally increased, while the South Polar area has actually cooled...We have to be careful in interpreting "averages."...If your 3rd cousin wins the multi-million dollar lottery, your "family wealth average per person" increases substantially, but are YOU any richer?...We don't have a Warming Problem. We have an Energy Mixing Problem.
Add in the fact that while the Lower Troposphere has warmed, the Stratosphere has cooled. Doing a triple integration of temps over lat, long & alt, and we have no net change in energy content of the atmosphere.

Hoping in this thread we can follow the rule where you have to back up what you say with a link.. Ie, fact check yourself. no link.. no credibility. Not a thread for opinions or "as I have said before", hopefully you can find a science based link that agrees with you.
A deception trick is to try and down play what 1C of warming means. But its just how climate change is measured and is a measure of how much energy has been added to the planet system. From this link (please provide links for everything) https://www.theguardian.com/environm...omb-per-second
Quote:
A Guardian calculation found the average heating across that 150-year period was equivalent to about 1.5 Hiroshima-size atomic bombs per second. But the heating has accelerated over that time as carbon emissions have risen, and was now the equivalent of between three and six atomic bombs per second.
Global green house trapping causes energy to be added to a non-linear system with feedback and energy storage. Add more energy to a non-linear system and it oscillates harder, faster and weirder. Ie, we get things like a record breaking 2020 Atlantic hurricane season..
The extremely active 2020 Atlantic hurricane season is drawing to a close with a record-breaking 30 named storms and 12 landfalling storms in the continental United States. While the official hurricane season concludes on November 30, tropical storms may continue to develop past that day.
There is good reason to fret: 2020 is the worst fire season on record, with nearly 13 million acres burned, 14,000 structures destroyed, and fire suppression costs reaching the $3 billion mark.
A deception trick is to try and down play what 1C of warming means.
The counter-argument is that the Warmists try to exaggerate the meaning of one lousy degree....Please demonstrate for us with some concrete example the impact of a 1 deg increase in average temps....You can't.

. Record breaking seson?..After falling numbers for a decade or twohttps://www.bing.com/images/search?v...RST&ajaxhist=0Average since 1850 is flat line. Warmists like to blame hurricanes on warm weather...In fact, hurricanes are driven by pressure, not temperature differences. Don't give me the BS about what "experts" say-- I know plenty of cardiovascular surgeons who actually do the procedure themselves still calling CABG "open Heart surgery." It isn't. They don't open the heart.
Blame TreeHugging govt regs, not the weather....You do realize Giant Sequoias, for instance, can't reproduce without periodic fires to open their cones?
..And by all means, let's only regurgitate opinions of "experts" with an agenda. God forbid anyone here actually look at data, analyze it and form their own opinions & conclusions....No Free 'Thinking allowed anymore. New Administration.
