It’s good to see how many climate scientists read OLO. I am not one of those and shall leave to others arguing with silly claims like that greenhouse theories have been debunked. Perhaps first reading what the American Institute of Physics says https://www.aip.org/history/climate/co2.htm would be a good idea. As for Roy spencer at UAH, I regularly go his website http://www.drroyspencer.com/ for UAH satellite updates and his own climate interpretations. Please tell me where he denies that carbon dioxide is a greenhouse gas. He certainly doesn’t do it in his ‘Global Warming 101’ section, though he does argue that other factors are involved, a possibility which I have already acknowledged. It’s worth adding that Spencer is a creationist. Strange but true, see e.g. http://theevolutioncrisis.org.uk/testimony2.php. I don’t hold it against him, though perhaps I would at crunch time. But there is no crunch; Roy Spencer is happy to accept greenhouse theory, at least qualitatively. Anyway, please read what I actually wrote. There you will find that you can still enjoy heavy doses of scepticism on climate change without putting your feet into it.

Jennifer Marohasy, this 'article' is a very trashy, disjointed, false, fraudulent and manipulative piece of work. As an author I truly believe (and could prove that if I felt it was worth the time & effort - it isn't) that you are incompetent to write a single credible word on the state of climate science. It is obvious that you do not comprehend any of it. Jennifer, your article is an insult to people's intelligence.

For the benefit of Jennifer Marohasy, which also fits those she has referenced as being "authoritative" in the field when they are not:

The Dunning–Kruger effect is a cognitive bias in which low-ability individuals suffer from illusory superiority, mistakenly assessing their ability as much higher than it really is. Dunning and Kruger attributed this bias to a metacognitive inability of those of low ability to recognize their ineptitude and evaluate their ability accurately.

These are tell-tale indicators of the Dunning-Kruger effect. Dunning and Kruger proposed that, for a given skill, incompetent people will:

– fail to recognize their own lack of skill
– fail to recognize the extent of their inadequacy
– fail to recognize genuine skill in others
– recognize and acknowledge their own lack of skill, after they are exposed to training for that skill

Dear Jennifer Marohasy the Earth's not flat either,if you want to shill from the frauds who back you tell us at least how much various US organisations are paying for your opinion.
Because like that British idiot Monckton and the rest of the OZ deniers your all on about the same level as the new one nation member of the senate NUTS.

Let's get real shall we Jennifer and try a 500 million years graph instead? see https://goo.gl/1KL5nM

Add half a life time of studying climate science and all the other related scientific based knowledge and maybe you and malcolm roberts could slightly begin to understand what that graph actually means and is saying to the world in 2016?

7.2 billion people live on the earth at once. Motor vehicles seems to reduce a working classes need to have many more children. The idea of modern industrial age living was to reduce population growth.

The alternative to living in CO2 increasing societies is to live like Indian poorest class peasants in hot climates. Cold climate societies need heat during many months of winter.

If talking about reducing CO2, may as well talk about reducing population growth.

More conversations on climate change should be directed at convincing middle eastern countries to reduce their population growth to a sustainable number. Western countries would not need to except immigrants into their countries.

Western countries would not need to bomb Middle Eastern countries to create disruption. Middle Eastern women finding disruption not ideal opportunities to have more children.

Bad school education, teaching children to believe what children are told; stopping children from realising better thought out ideas. Children so distracted by sports and mentally stressing education. Children grown into adults, adults can't conclude anything other than what media points to.

Australian silliness and July 2016 temperature records by Gavin Schmidt NASA/GISS Scientist

July 2016 was absolutely the hottest month EVER since the instrumental records began.

Before that July 2015 was the hottest month EVER recorded.

Can y'all please stop spreading lies, conspiracy theories, and disinformation about climate science, climate scientists, the scientific data, and global temperatures?
