You are thinking of geostationary satellites that orbit the equator.

Polar orbiting satellites orbit north/south. NOAA run 2 polar orbiting satellites constantly. The European Space Agency run 2 polar orbiting satellites called MetOp. NASA also run polar orbiting satellites. These satellite groups have onboard a wide range of instrumentation including temperature measurement with very high accuracy.

Are you saying we have no temperature data for the Arctic and Antarctic?

UAH (the satellite group from the University of Alabama Huntsville) went AWOL (was badly calibrated). It's been fixed (now includes adjustment for diurnal cycles that come into play as satellites drift).

Sorry, I meant November 2016.

Thanks. I'll summarise the article for those who can't be bothered to read it.

There are multiple groups of satellites that collect temperature data. Turns out that one of the groups was badly calibrated and showing results different to the others by a factor of 3. That was in 2015 and has been corrected. Satellite groups and Arctic weather stations measured -5C when they were expecting -25C in November 2017.

We don't need to stop having children, just fewer than 2 per woman on average, then population growth would slow down and eventually start decreasing.

Religion is the problem, because brainwashing children is the only way religious nonsense can be sustained, therefore religions generally encourage followers to go forth and multiply within the same faith.

It's not the fault of religious parents, it's just how evolution works - all parents pass their beliefs on to their children, and children believe what their parents teach them.

The Arctic and Antarctic have been monitored by polar orbiting satellites since the 70s. https://www.ncdc.noaa.gov/monitoring-references/dyk/arctic-ice Scientists are really interested in what happens at the poles because they are warming the quickest, especially the Arctic since much of the ice is floating on water which stores heat better than rock. I believe the Arctic is warming 3 or 4 times faster than most of the rest of the planet.

Computer models predicted -25C. Arctic weather stations and polar orbiting satellites measured -5C. Observed reality is worse than the predictions, suggesting the climate is more sensitive to changes in the composition of the atmosphere than we previously thought. Basically, we're flucked.

I'm uploading some common sense. 20F is about 1/3 of 20C. 20C above normal is not normal. -25C was expected, -5C was measured in November 2016 over most of the Arctic. https://www.theguardian.com/environment/2016/nov/22/extraordinarily-hot-arctic-temperatures-alarm-scientists

We've been through this many times before. Either update your ideas, or tell me where I'm wrong and teach me something - otherwise you just sound like a child with learning difficulties.

Climate data prior to 1880 is not rejected, it is simply less accurate because it is indirect - for example, if the Romans had vineyards in Scotland, then the Scottish climate was conducive to growing grapes during Roman times. It doesn't tell you much about the climate at the South Pole at the time.

1880 was when we began measuring the temperature with actual instruments around the planet. When you hear "... on record" or "... when records began" or something similar, that means since we started measuring global temperature with instruments, ie. 1880.

And again, we have been through the point you keep repeating like it's the only idea you've got - that the climate has been warmer before humans existed, therefore humans are not responsible for the warming we are experiencing today. It doesn't work. Most warm periods in the distant past were the consequence of higher concentrations of greenhouse gases. Just like the warming today.

The extremes of AMO cycles (Atlantic Multidecadal Oscillation) vary the temperature about 1F. The cycle we are in right now started around the mid 1990s. http://www.aoml.noaa.gov/phod/amo_faq.php So AMO cycles cannot account for the 20C warmer North Pole than expected that was measured this winter, and the Greenland ice melting 600% faster than computer models predict.

We are coming off the El Nino cycle, which has an overall warming effect, moving into the opposite which is La Nina, which has an overall cooling effect. So El Nino/La Nina cannot account for the extreme temperatures and melting measured this winter, especially if combined.

I wish you were right, but you're not. Got any more theories?

You know on a graph showing an exponential curve, where the rise at the beginning starts slowly with little change, and then the graph becomes steeper, and shortly afterwards it becomes almost vertical - I think on climate change we are at the beginning of the almost vertical phase. That is very scary. The next few years will confirm this, or not if Trump is right and climate change really is a hoax perpertrated by the Chinese. http://cdixon.org/2015/05/12/exponential-curves-feel-gradual-and-then-sudden/

I agree with much of what you say about nature, that it is cruel and unfair, and ultimately selfish. But fairness and morality are human inventions that differentiate us from the rest of the animal kingdom.

I think the evolution of man is about changing from your description of nature, to societies that incorporate fairness and "good" morals - primitive societies being closer to nature as you describe, civilised societies trying to incorporate fairness and morality, so far with chequered success.

Fossil fuels are heavily subsidised. In the UK, BP and Shell receive about £6 billion a year in subsidies, about double that of renewables. http://www.independent.co.uk/news/uk/politics/uk-government-pays-6bn-a-year-in-subsidies-to-fossil-fuel-industry-a6730946.html

I don't want to sound too selfish but I'd prefer to live in a world of peace and love than one of conflict with the threat of extinction. Don't know about you but I'm enjoying life, and I suspect you are too - otherwise you wouldn't be brushing off the threat of extinction like water off a duck's back.

The upside is that if we do survive this period, ie. stabilise the climate and create a sustainanble world to prosper on, then humans (or the new life forms that we create), may outlive our sun.

Sure Earth has existed for billions of years before humans, and  could well exist for billions of years more after humans - I vaguely remember something about our 5 billion-year-old sun being half way through its life.

The problem is that a climate NOT capable of sustaining civilisation as we know it, is on the horizon - probably within your lifetime. Apart from sea level rise threatening our major coastline cities; and heat waves, droughts and other extreme weather events threatening almost everywhere on the planet; oceans warming and acidifying threatening sea life that many humans depend on - there will also be massive climate induced political conflict. If you think immigration is a problem today, you've seen nothing yet. About 1 million migrants/refugees moved to Europe in 2015. It is estimated that 15 million people will have to move from Bagladesh alone by 2050.

You should care if you're not on your deathbed because climate change will affect you, your family, and your friends. In fact it already does.

Is this the real reason that Trump doesn't want to receive daily intelligence briefings, too much reading?
