Time varying trend in global mean surface temperature
by Judith Curry “Our results also serve to highlight the importance of Atlantic multidecadal variability in mediating the rate of global warming, and they suggest that these variations deserve more explicit consideration in twentieth century climate simulations and in attribution … Continue reading

Why target Heartland?
Update: Email from Joseph Bast, President of Heartland Institute, appended at the end of the post. So, imagine you are a climate scientist and climate change ideologue, and want to “take down” the single organization (or individual) that is doing … Continue reading

A biologist’s perspective on ice ages and climate sensitivity: Part I
by DocMartyn This is the first of a three part presentation where I will attempt to explain the climate of the last 800,000 thousand years, drawing on the role of the biosphere’s response to interstellar dust.

Tropospheric and surface temperatures
by Donald Rapp Santer et al. (2005) emphasized that “a robust feature” of climate models is that increasing greenhouse gas concentrations will amplify warming in the middle and upper tropical troposphere (compared to the surface). It was then with some … Continue reading

Trends in tropospheric humidity
by Garth Paltridge It is difficult these days to get a paper published in a mainstream climate journal if it emphasises the uncertainty associated with some basic aspect of global warming.
Climate sensitivity to ocean heat transport
by Judith Curry A paper in press in the Journal of Climate provides some insight into the interaction of cloud feedback with ocean heat transport.
