CONUS GHCN Precipitation

I looked at the GHCN Precipitation data. PRCP stations are not as prevalent, nor as old as the temperature stations so shorter time frame, since 1930, includes these stations:

Global Extreme Heat in the GHCN

After examining the record of CONUS stations in the GHCN TMAX record, it is quite reasonable to ask ‘What about the global record?’ I looked the global GHCN data ( excluding the US stations, which dominate the record, especially early … Continue reading

AGW and Extreme Heat in the US

As part of his 2016 Congressional testimony, John Christy presented this chart:

CO2 and the Last Glacial Maximum

Introduction Often in the context of Anthropogenic Global Warming (AGW), comparisons are made to the changes of CO2 during the glacial cycles. Running the CRM models as in the last post, I compared runs for the Last Glacial Maximum and … Continue reading

Global Warming in the Context of Glacial Cycles

Synopsis Using the Column Radiation Model, GFS analysis data for 2010, CERES derived surface albedo, and Last Glaical Maximum (LGM) ice and land mask estimates, it is possible to compare resulting net radiance for a number of scenarios ( with … Continue reading

‘Global Warming’ not ‘Climate Change’?

Global Warming Appears Likely As countless papers have demonstrated, the increased opacity from increased carbon dioxide tends to impose a surplus of radiative energy which, if not reversed by strong negative feedback, would tend to accumulate, raising temperatures until radiative … Continue reading

Upper Air Update Through 2015

With 2015 in the books, I updated a couple of plots I monitor of MSU data and RAOB ( RATPAC ) data. There’s been some discussion about the Hot Spot missing because of the cooling trend in the Eastern Pacific, … Continue reading

RATPAC and UAH, Together Again

A frustrating aspect of observing climate change is the lack of uniformity within the major global data sets. Variations of instrumentation, infrastructure, methods of observation, automation, time of observation, standards,  effects of human habitation and numerous other discrepancies pollute data … Continue reading

The Distribution of Water Vapor Changes Radiative Forcing

Continuing with runs of CRM, I recently set up a comparison of water vapor. In this comparison are runs of increased water vapor for the entire troposphere and then for just the lowest two levels. For these runs, dewpoint depression … Continue reading
