Up to its old tricks, WattsUpWithThat (WUWT) has a post by Christopher Monckton "updating" the number of years and months supposedly without warming. Once again, Monckton arbitrarily uses satellite surface temperature data (excluding ocean and observational data) to draw a trend line, using the exceptionally warm El Niño year of 1998 as the starting point for his "analysis." With these highly problematic parameters, Monckton is able to contrive a flat trend line showing that surface temperatures have "not gone up in over 18 years."
So what happens if you add in the data Monckton purposefully left out? Here you have the full RSS satellite data since 1980, which shows a positive warming trend. Then you have NOAA's and NASA's combined land and ocean temperature indices, which show a 0.8°C increase in global temperature since the start of the 20th century. Now which version—Monckton's, or the combined temperature analyses'—seems more likely, given that 2014 was the hottest year on record and nine out of the then hottest years on record have occurred in the 21st century?
Rather than accepting the steady increase in globally averaged annual temperature across recent decades, Monckton ignores how natural cycles like El Niño and La Niña events impact surface temperatures, takes a smoke-and-mirrors approach to long-term trends and disregards the heat going into the ocean.
It's denier tactics, not climate, that haven't changed.
