spot on yes averages can be taken out that many places but that is NOT what i am discussing, my POINT is the ACCURACY of those averages is nothing  close to the precision needed to claim accuracy to within hundredths of a degree..... in summary yes you can average many number out to many decimals places but that is NO WAY means the final result is an accurate scientific reading.

you example above gives an average NOT a meaningful single average for that area.......nowhere in that area likely was 50.001, so that number in reality has no useful info or meaning

plus or minus .1 degreeC does NOT give one accuracy to within hundredths of a degree.

The issue doesn’t mean measuring sea ice extent or area is not science. The issue concerns limitations of satellite-based measurements and the concept of margins of error. Statistically, when error is considered, measurements within 40,000 km2 are treated as being the same.<<<

TY so now we have a large margin of error when taking a picture and measuring it, YET your side still claims to have precision in a single global temperature to within hundredths of a degree.....and no mention of any margin of error in those claims.

bottom line = the claims we humans are the cause of climate change is IDIOCY and not one shred of science backs that claim.

>>>>Values within 40,000 square kilometers (15,000 square miles) are considered tied.<<<

new rules for sports = in baseball scores within 2 runs are considered tied, in football scores with differential of less than 7 are considered tied, in bowling scored less than 10 pins different are considered tied......

in laymans terms this ice measuring stuff is NOT SCIENCE, the results are what we declare them to be NOT the actual results.

"Our CO2 emissions will remain in the atmosphere for centuries to millennia, maintaining the warmer temperatures long after these emissions were released."

the TRUTH = some of that co2 gets removed daily by the plants using it as FOOD........

"Human activities have caused a 1.0°C rise in the global temperature over the past 150 years."

TRUTH = the earth has warmed that much since coming out of the little ice age, YOU nor anybody else has any evidence that humans are the "cause" of this happening.......

with all due respect the ONLY science says the past does NOT cause todays weather, it says the current weather is what is causing the weather events again NOT the average stats from the past.what precisely are you claiming the average weather stats are DOING to cause weather today?

the weather constantly changes = FACT

any stats derived from constantly changing input will constantly change = FACT

claims that climate change is unusual = SILLY and ignores basic science fact.

we have observed periods of cooling and warming ever since we have observations..

we have NOT seen any periods of unchanging constantly the same weather(and climate since the climate is just a description of the previous weather).

"climate change" has never caused even one weather event.......the climate describes the PAST and is used to see what the usual conditions are(average), but again the climate is not a force has no power and has never caused any weather event.

the above post is a vicious attack on an honest person.........Iceland IS a highly active volcano  area, to claim there is nothing to support the claim some heat could be coming from under OK is just a LIE.

the climate is just the STATISTICS derived from the previous 30 years weather for a given area.......to think the past CONTROLS the future shows a complete lack of basic sense about simple science....the past also has no control over the present, the climate is NOT a force, has no power and has never caused even one weather event.......

folks pollution is something that is NOT supposed to be there, co2 is REQUIRED being in our air for us to be alive..........of course too much of anything can kill you........but just because too much ice cream can kill you calling ice cream poison would be stupid and false,and those claiming co2 is pollution are LYING and not engaged in science on any level.

co2 is NOT "pollution"  it is a nutrient required for life as we know it........

the IR wave does NOT "some of the heat that would otherwise escape is re-radiated to the earth"   it is released with no direction imparted and continues its natural movement towards space....

science FACT = no insulator ever "traps heat"   slow its movement YES, but "trap" it never happens......

note i make no personal remarks about any poster.......how was my factual post silly please?.......the measurement used in is hundredths of a degree and our precision in gathering the data is nowhere  near that exact.......the above graph shows warming when coming out of a colder period, how is that unusual please?

the ranking of warmest is based on hundredths of a degree a precision we do not have the ability yet to find.

this particular warming event? it was warmer in 1998  than now, there is NO ongoing warming at this time.........

dons i made no mention of you.......they made that rather silly claim and now you posted this "(relatively stable since the 1960s with some fluctuations)."   that clearly says there have been fluctuations since the 60's = NOT a constant rate of incoming from the sun.......to rule out the SUN and blame human released co2 for the warming remains INSANE.......

One of the “smoking guns” that tells us the Sun is not causing global warming ..........that clearly says the SUN does NOT cause warming on earth........ they said 55% of records were broken which means 45% were NOT broken and it was warmer in the past......the climate is the PAST weather stats averaged, it is NOT a force, has no power and does NOT cause any weather event.

to claim the SUN does NOT cause global warming is utterly insane........

it seems as if many here WANT catastrophic warming......hoping the ice melts

quick english lesson = concerning is NOT a noun it is a preposition but many use it wrongly as a noun today....also worrying is a verb NOT a noun, 

i see radar lighting up big time in east texas and it is only 30 here in walker county bama......also a tiny bit of snow in the air west of me in mississippi

why do some people hope severe weather happens? 10+ people died this afternoon in bama

lol the psyche ward has had 3 or more big storms in the next week down to warm rain and thunderstorms now......every new model runs changes everything there
