temperature correlates tightly with solar activity and magnetic field variability.
Graphs show A) six - month winter (November to April) rainfall, B) annual
temperature, C) annual soil moisture, and D) total population.
The decreasing rainfall (
shown in the top
graph below) combined with rising
temperatures (second

graph), the researchers say.

show the results in a chart or
graph.

graphing to the exercise above: Students can create a bar
graph or a line chart to
show the average
temperatures throughout the season.
The
graphs of
temperature ALL
show that current temps are far higher than in the 70s, but Fred still spouts goop.
However, if the CO2 ppm were extended back to say 1905, the
graph would
show a strong disconnect between the rise of the CO2 concentration and the global
temperature between 1905 and 1945.
In the annual mean values and particularly for the
temperatures since the Second World War, the corrections are minimal, as the following
graph shows:
Look at the
graph in the fact sheet which
shows the tropical surface

temperature Vs year, 1980 to 2005.
The most revealing item is Gavin's «Colocated Anomalies»

temperatures (NMAT in green).
The

The
graph he used had a five year moving average which

Their

temperatures in the two forecast intervals (green points
shown at 2005 and 2010) are almost the same and are both lower than observed in 1994 - 2004 (the end of the red line in their
graph).
The same holds for the specific global mean EIV
temperature reconstruction used in the present study as
shown in the
graph below (interestingly, eliminating the proxies in question actually makes the reconstruction overall slightly cooler prior to AD 1000, which — as noted in the article — would actually bring the semi-empirical sea level estimate into closer agreement with the sea level reconstruction prior to AD 1000).
I also note that Keigwin appears to
show a change in
temperature of about 2.5 C between the LIA and MWP (from his
