The Version 6.0 global average lower tropospheric temperature (LT) anomaly for May 2017 was +0.45 deg. C, up from the April 2017 value of +0.27 deg. C (click for full-size version):

Global area-averaged lower tropospheric temperature anomalies (departures from 30-year calendar monthly means, 1981-2010). The 13-month centered average is meant to give an indication of the lower frequency variations in the data; the choice of 13 months is somewhat arbitrary… an odd number of months allows centered plotting on months with no time lag between the two plotted time series. The inclusion of two of the same calendar months on the ends of the 13-month averaging period causes no issues with interpretation because the seasonal temperature cycle has been removed as has the distinction between calendar months.

The global, hemispheric, and tropical LT anomalies from the 30-year (1981-2010) average for the last 17 months are:

0.45 Celsius degrees or 0.81 Fahrenheit degrees. Imperceptible to your average human. Since visiting the Hoover Dam, I’ve been watching Lake Mead ‘s water level. it’s up a little over previous years but not what you’d expect after the huge snowfall in the Rockies. Well, it’s been colder than average, so the snow is still up there.
Glaciers and ice caps form when snowfall exceeds snow melt. How many global warming disciples understand that process ? Snowfall is weather ,not climate. When you take data and average it over 30 years, that’s climate.
What’s the weather forecast for July and August? Not sure? Why would anyone predict the next 30 years? If the temperature increased another 0.45 Celsius degrees by 2047, how much could be attributed to us versus solar cycles? How could you answer that ?
