I can't claim to be a whiz at statistics but I remember telling some skeptics on another forum, Accuweather / climate change I believe, that the major point and problem with this paper were that the results still

And in some articles where I have read that it is being observed, often historical data
shows those cities and / or regions to have been

His position: • No evidence of increasing lake clarity as a result of secchi measurements since 1946 • The interplay of stratification and plankton productivity are not «straightforward» • Challenges O'Reilly's assumption on the correlation of wind and productivity - the highest production is on the end of the lake with the lowest winds • A strong caution using diatoms as the productivity proxy (it is one of two different lake modes) • No ability to link climate change to productivity changes • More productivity from river than allowed for in Nature Geopscience article • Externally derived nutrients control productivity for a quarter of the year • Strong indications of overfishing • No evidence of a climate and fishery production link • The
current productivity of the lake is within the expected range • Doesn't challenge recent temp increase but cites temperature records do not
show a temperature rise in the last century • Phytoplankton chlorophylla seems to have not materially changed from the 1970s to 1990s • Disputes O'Reilly's and Verbug's claims of increased
warming and decreased productivity • Rejects Verburgs contention that changes in phytoplankton biomass (biovolume), in dissolved silica and in transparency support the idea of declining productivity.
The strength of the Icelandic Low is the critical factor in determining path of the polar jet stream over the North Atlantic In the winter the IL is located at SW of Greenland (driver Subpolar Gyre), but in the summer the IL is to be found much further north (most likely driver the North Icelandic Jet, formed by complex physical interactions between

warming.

warming) and incidently the PPM of CO2 measured higher than
current levels.

- Notice, during the
current cold phase, there has been permanent ice caps in Antarctica for only 10 million years and at the North Pole for less than 5 million years (demonstrating that ice caps are a rare event in Earth's history, which
shows we are in a cold phase)- Notice that the planet has had no ice caps — therefore it has been much
warmer than now — for about 80 % of the past 500 million years.

shows that natural internal variability, as simulated by
current climate models, is a highly unlikely explanation for the observed lower tropospheric
warming over the satellite era»

shown that the
warm phase of the AMO corresponds to a strengthening of the Atlantic meridional overturning circulation (AMOC) and a weakening of the Atlantic subtropical cell (STC), which both induce an anomalous northward
current in the TNA subsurface ocean.

show warming.
