Bill Nye is so worried by climate change he goes to see the eminent Austrian psychiatrist Dr Arnold Schwartzenegger... (documentary episode)
It is interesting that a Rupert-Murdoch-owned TV channel will be showing a powerful documentary series about climate change just before the Nov 8 election.
Odious is constantly banging on about disappearing ice that just refuses to disappear! He's comparing non believers to holocaust deniers and now he's using Bill Nye to prop up his religion, he's gone down the rabbit hole.....
1. Air Temperatures Over Land are Rising.
2. Air Temperatures Over Oceans are Rising.
3. Glaciers Around the World are Melting.
4. Arctic Sea Ice is Shrinking.
5. Sea Levels are Rising.
6. It's Getting More Humid.
7. Our Oceans are Storing More Heat.
8. Sea Surface Temperatures are Rising.
9. Snow is Decreasing in the Northern Hemisphere.
10. The Temperature of Earth's Lower Atmosphere is Rising.
That's right, temperatures over the last century or so are up about a degree, glaciers have been receding and sea level rising for decades if not centuries, and rainfall and humidity are up.
So What about it? What's your point? Why Should I or anyone else care?

Visit Met Eireanns website and go to Past Weather > Monthly Data > Belmullet
2015 - 10.0c
2014 - 10.7c
2013 - 10.2c
Unadjusted or homogenised that chart by Owedtojoy is plainly wrong.
It is a good point, though overstated. It is hard to say what is "wrong" when the standard is fuzzy. No one knows what process the Met Eireann data has been through, so that may have been adjusted.
There are only 3 years of data, and the NASA record contains gaps so that only 31 months are available to compare. IN this case, the NASA unadjusted data is identical to the homogenised.
ME refers to Met Eireann, MMaxMin_ME is the average of maximum and minimum temperatures recorded by Met Eireann for the day.
There are 5 significant differences, three above and two below, all but one taking the same value (11.1), and they are clearly wrong, IMHO. especially 2013-3.!
Unfortunately, Met Eireann do not publish a free average temperature record from any station, but they do publish the Max and Min Temps for each day, and using the average of these we can look at the long-term effect of the differences on the temperature trend.
In fact, the discrepancies make no differences to the long term estimates - the Belmullet trends are not (statistically) significantly different from NASA or from Met Eireann.
This is where the anti-NASA propaganda completely fails - because NASA publish their data openly, and invite criticism, it is easy to find errors and lacunae. NASA use over 2,000 station worldwide to construct their record, and it would be surprising (indeed, absolutely amazing!) is these were all pristine and error-free. Efforts are made to upgrade the system all the time. Other temperature monitoring organisations (e.g. NOAA, UK Met Office, Berkeley Earth) use different algorithms.
But no one has ever shown a case where local effects have had a significant impact on the global temperature average. Random errors in stations will cancel out over the whole system.
If Arctic Ice keeps melting at the current rate for the year, it will end up at about 4.75 million km^2, as a minimum, one of the 10 lowest ever, possibly one of the 5 lowest ever.
A prediction that this year will see the second lowest Arctic Ice Extent ever. Could happen, if it gets below 4.3 million km^2. It just hit 4.9 today, and the melt rate is about -0.05 km^2 per day, though that will slow. It is about 3 weeks to the minimum, though that could happen early.
A 2nd lowest is possible, but I am still looking for Top 5.
