I wholeheartedly agree with David’s comments, in particular the need to show graphs.
I am sometimes accused of cherry picking or coming to different conclusions to others. But what I always try to do is actually show the graph, so readers can form their own opinions.
While we are on the topic, I will put up that Woodfortrees graph, which I posted yesterday. According to Woodfortrees, the warming trend since 1950 has been 0.012C/yr, or 1.2C/C.
Yet the BBC report, referred to by Dr Whitehouse, actually states that:
If the trend continues, the WMO says temperatures may rise by 3-5C by 2100.
This claim clearly is not compatible with the historical data
Fig 2 shows the same data with error bars from which it can be seen that 2018 is statistically equivalent to some years before the El Nino event.

Alternate Title: The Annual Cycle in Global Land+Ocean Surface Temperature IS Far Greater Than 1.5 Deg C, AND Much-Much-MUCH Greater Than 1.5 Deg C Annually for Global Land Air Surface Temperatures
We all were taught early in school that the Earth orbits the Sun…that its path is elliptical…that because of the tilt in Earth’s axis of rotation, we have seasons as the Earth orbits our star annually. Because of the elliptical orbit, and because the ratios of land to ocean are different between the Northern and Southern Hemispheres, we might expect that global average surface temperatures would vary over the course of a year.
Later in life we’ve been brow beaten with alarmism about human-induced global warming and climate change…that the Earth will become a literal—not figurative—hell if global surface temperatures rise—formerly 2-deg C—now 1.5 deg C above pre-industrial levels. But does the average person know much global surface temperatures vary annually as it orbits the Sun? It’s unlikely, because I’ve never before seen graphs that are similar to what’s presented in this post or seen it discussed in any of the global warming literature. Am I expecting most persons to find this information to be of any interest? Nope. I simply find it noteworthy that, as I mentioned before, I’ve never seen it presented anywhere. In fact, I just Googled, in quotes, “How Much Do Global Surface Temperatures Cycle Annually?” and Google replied (their boldface), “No results found for “How Much Do Global Surface Temperatures Cycle Annually?”.
Remarkable, is it not, in these times of global warming interest?
Enough with the preamble and on to the meat of the post:
