AGW Falsified: NOAA Long Wave Radiation Data Incompatible with the Theory of Anthropogenic Global Warming

ANTHROPOGENIC Global Warming (AGW) theory claims the earth is warming because rising CO2 is like a blanket, reducing Earth’s energy loss to space. However, data from the US National Oceanic and Atmospheric Administration (NOAA) shows that at least for the last 30 years, Earth’s energy loss to space has been rising. The last 30 years [...]

Why I am an Anthropogenic Global Warming Sceptic: Michael Hammer

I HAVE been asked several times ‘why am I so sceptical of the anthropogenic global warming (AGW) hypothesis’?  There are many reasons, some of which I have documented in previous articles at this weblog, but these have relied on sometimes complex calculations which I admit can be difficult to appreciate.  So I would like to outline here [...]

A Climate Change Paradox (Part 2)

AUSTRALIA’S Minister for Climate Change, Penny Wong, recently suggested that most of the global warming since 1960, about 85 percent, has happened in the oceans and that change in ocean heat content is thus the most appropriate measure of global warming.   In my previous post, working from first principles, I determined a discrepancy of 9:1 [...]

A Climate Change Paradox

AUSTRALIA’S Minister for Climate Change, Penny Wong, recently suggested that most of the global warming since 1960, about 85 percent, has happened in the oceans and that change in ocean heat content is thus the most appropriate measure of global warming.    But, calculating from first principles, according to this data the oceans have absorbed far [...]

How the US Temperature Record is Adjusted

There has been criticism of the potential for official weather stations in the USA to record artificially high temperatures because of the changing environments in which they exist, for example, new asphalt, new building or new air conditioning outlets.   Meteorologist, Anthony Watts, has documented evidence of the problem and Canadian academic, Ross McKitrick, has attempted to [...]

Hot City or Global Warming?

An analysis of the historical temperature data for the state of Victoria in Australia, including the city of Melbourne, suggests an Urban Heat Island (UHI) effect but no general warming trend. Urban Heat Island versus Global Warming – A Study of One Region By Michael Hammer CITIES represent concentrations of commerce and energy use.  This [...]

DIY Modelling of Climate Change

GLOBAL warming theory is not that complicated.  According to Michael Hammer it can be incorporated into a simple model which readers can build themselves on an excel spread sheet.  Mr Hammer gives detailed instructions and formulae to enter for his DIY climate change model.  The model then calculates the temperature rise from carbon dioxide plus water [...]

Pondering Problems with Computer Climate Models: A Note from Michael Hammer

SCIENTISTS have put a huge amount of effort into generating computer models of our climate system.  These models are very sophisticated and complex and their outputs suggest that increasing carbon dioxide will lead to significant temperature rises for our planet.  Indeed the model outputs now represent the main evidence in support of the anthropogenic (man induced) [...]

A Reality Check on the Role of Water Vapour in Climate Change: A Note from Michael Hammer

ACCORDING to the international panel on climate change (IPCC) any direct temperature rise from increasing carbon dioxide levels is greatly amplified by positive feedback from water vapour. As the theory goes, rising carbon dioxide levels from human activity causes some temperature rise which causes more water to evaporate.  Because water vapour is the dominant greenhouse gas, [...]

Radical New Hypothesis on the Effect of Greenhouse Gases

CLIMATE is complex but in an attempt to understand the effects of increasing levels of atmospheric carbon dioxide on global temperatures simplified General Circulation Models (GCMs) have been developed and are used by the United Nation’s Intergovernmental Panel on Climate Change (IPCC).      Al Gore, in his famous movie ‘An Inconvenient Truth’, explained that as the concentration [...]
