Energy balance and the oceans
Climate forcing relies on an imbalance between incoming solar energy and outgoing IR energy at the TOA (top of atmosphere). The CERES instruments monitor radiation fluxes at the TOA and has measured this imbalance over the last 11 years [1]. … Continue reading

H2O decreasing while CO2 rises !
Dire predictions of global warming all rely on positive feedback from water vapor. The argument goes that as surface temperatures rise so more water will evaporate from the oceans thereby amplifying temperatures because H2O itself is a strong GHG. Climate models … Continue reading

Marcott – Proxy errors and conclusions
There has been a lot of discussion (see here) about the treatment of errors by Marcott et al. through their Monte Carlo analysis. Since I avoided any interpolation or Monte Carlo by using only the measured values for each proxy, … Continue reading

Detecting peaks in Marcott data
New: Simulation of a 20% uncertainty in proxy resolution time and peaks practically disappear. Have there been previous warming periods over the last 10,000 years comparable to current warming ? If so would Marcott proxy data have been able to … Continue reading

Map of Marcott Proxies
The map below shows the location of the 73 proxies provided by Marcott el al. “Mouse over” gives the name of the station and a click on the dot shows the graph of the measured temperatures and anomalies (relative to … Continue reading

Evidence that Marcott’s up-tick is an artefact
I have calculated from scratch the global averaged temperature anomalies for the 73 proxies used by Marcott et al. in their recent Science paper. The method used is described in the previous post. It avoids any interpolation between measurements and … Continue reading
Marcott Study
There has been much media interest in a recent paper by Marcott et. al “A Reconstruction of Regional and Global Temperature for the Past 11,300 Years” published in Science. It seemingly shows that following a slow cooling over the last … Continue reading

Beware which way the wind blows.
Total UK electricity power demands are made available by the National Grid. A Live control panel can be seen here. These figures are a real eye opener and should be made compulsory reading by lobbyists and politicians. They highlight how … Continue reading

Water Vapor Decline Cools the Earth: NASA Satellite Data
Guest post by Ken Gregory P.Eng., Friends of Science.org Original article at http://www.friendsofscience.org/index.php?id=483 An analysis of NASA satellite data shows that water vapor, the most important greenhouse gas, has declined in the upper atmosphere causing a cooling effect that is … Continue reading

Radiative Forcing of CO2
This post examines how radiative forcing depends on CO2 concentrations in the atmosphere. In CO2 greenhouse demystified, we calculated the effective emission height where “thermal” photons escape to space . This height depends on the lapse rate temperature and defines … Continue reading
