A big story at the beginning of each year is the release of the global surface temperature of the previous year. A big story certainly but not often a surprising one.
Since the beginning of the century it didn’t change much from year to year until the 2015/16 super El Nino came along. Then the temperature went up, as usual, and now it’s coming down again.
Since the beginning of the century, it didn’t change much from year to year until the 2015/16 super El Nino came along. Then the temperature went up, as usual, and now it’s coming down again.
The year 2018 was the fourth warmest year of the instrumental period (started 1850) having a temperature anomaly of 0.91 +/- 0.1 °C – cooler than 2017 and closer to the fifth warmest year than the third.
But of course, there are those that don’t like to say the global surface temperature has declined.
The UK Met Office released the 2018 global temperature data as part of a press release about its forecast for global temperatures for the next five years, basically saying that the high temperatures will continue, despite their elevation over previous years by the El Nino and they’re coming down afterward!
Their press release was entitled, “Forecast suggests Earth’s warmest period on record.”
It says: The forecast for the global average surface temperature for the five-year period to 2023 is predicted to be near or above 1.0 °C above pre-industrial levels, says the Met Office.
If the observations for the next five years track the forecast that would make the decade from 2014 to 2023 the warmest run of years since records began.
No mention then of the events that elevated the global 2015 and subsequent years, the EL Nino and the Pacific marine heatwave.
As we all know, especially the Met Office, forecasting the future is fraught with difficulties, the main one is that you are forecasting the future! The Met Office does not have a very good track record in this regard.
More recent forecasts have not fared well either showing little skill. The Met Office has a tendency to forecast a world that is warmer than it actually is.
Sometimes their climate forecast looks better than they were because an El Nino occurred that temporarily elevated global temperatures.
Fig 1 shows how off their forecast was. You can see that since 1997 they have always predicted way too high except when an El Nino helped them out in 1998 and 2015 -17. (click on the image to enlarge)
Looking at the same graph published in 2017 for previous forecasts (Fig 2, click on the image to enlarge) shows they failed in their 2016 – 2021 forecast.
The new forecast, according to the Met Office’s Professor Adam Scaife, may bring about “rapid warming globally” with a 0.55 °C warming by 2023.
At least it’s a testable prediction, as the rapid warming forecast in 2007 that didn’t happen.
Perhaps a better headline would be Global CO2 increases, Global temperature declines.
In a recent press release, the Met Office said that in 2019 they expect to see one of the largest rises in atmospheric carbon dioxide concentration in 62 years of measurements.
It will be fascinating to see if this forecast in a large rise in CO2 will finally push global temperature up. Each year as CO2 increases, it is increasing its ability to force the global temperature upwards.
El Ninos notwithstanding, it’s about time the global surface temperature started following the CO2. Expect interesting things in the next 1-5 years, one way or another.

I would just like to see what happens when it snows real deep on Al Gore or Leonardo DiCaprio and all those Eco-Wacko idiots from Greenpeace NRDC and EDF as well as all the rest of the wealthy Eco-Freak groups
As usual the whole argument depends upon there being a single value for pre-industrial global average temps. Even after much “adjustment” the hockey stick gives some variation in this.
This article touches on what is very common with the climate alarmist. Significant warming is always coming, but it never gets here. The entire climate change movement is based on predicted warming that never happens.
The first graph shows that there is little relationship between carbon dioxide and the earths averge temperature. There are other periods of time that show the same thing. One of the most compelling is that 40% of the warming blamed on man occurred between 1910 and 1941 when the carbon dioxide levels were relatively low and raising very slowly.
