What’s up with the Bomb Model?

In this post I present a simple ocean surface water mixing model that explains why 14C cannot be used to predict the sequestration rate of CO2. Each year the ocean inhales about 92Gt of carbon from the atmosphere that is tagged with 14C. This inhaled CO2 mixes with the 1020 Gt carbon in surface ocean water before about 90 Gt is exhaled. The CO2 exhaled is not the same CO2 that was inhaled and is depleted in 14C. Continue reading

Blowout week 39

Blowout lite this week with 16 links mainly to renewable stories. The story that caught my eye this week describes a massive $8billion Wyoming wind to Los Angeles renewables plan that includes compressed air storage in constructed salt caverns in Utah. In my opinion, all renewables projects should be mandated to provide load balancing capacity either through storage or fossil fuel based back up. Continue reading

What’s up with the Bern Model?

Modelling the CO2 evolution of the atmosphere by looking at what is sequestered provides insight to what is actually going on. I believe it is impossible to have an appropriate model that works by looking at residual CO2 that remains in the atmosphere. Continue reading

Global warming and extinct species: three case studies.

And it’s reported that the extinction process had already started. A number of species, it is claimed, have already been driven to extinction by climate change. But are these claims true? Are these species definitely extinct, and if so was climate change really the culprit? Continue reading

The Half Life of CO2 in Earth’s Atmosphere – Part 1

The fact that both single exponential decline and multi-time constant models of emissions can be made to fit atmospheric evolution of CO2 means that this approach does not provide proof of process. Either or neither of these models may be correct. But combined, both of these models do provide clues as to the rate of the CO2 sequestration processes. Continue reading

Eigg – a model for a sustainable energy future

A short distance off the west coast of Scotland lies the island of Eigg, area 15 square miles, population 87 (2005). It has never had a grid connection to the mainland, so historically its residents have either had to generate … Continue reading

For A Few Trillion Barrels More

Figure 1 shows the history of UK offshore field discovery. Since 1965, on average 12 fields have been discovered per year. The best year was 1989 with 29 discoveries. That was a bonanza! Professor Kemp’s forecast for the future is for 3 discoveries per year, one quarter of the historic average. Continue reading

Blowout week 37

Oil and gas industry expert Sir Ian Wood accuses Scottish nationalists of using overly optimistic figures on North Sea oil reserves which he dismissed as “highly speculative or even fantasy”. (He) warned there are only 15 years of reserves left before the industry’s decline starts wreaking major damage on the Scottish economy. Continue reading

HadCRUT4 strikes out

HadCRUT4, a joint production of the UK Met Office Hadley Centre and the Climatic Research Unit of the University of East Anglia, is the world’s “official” global surface temperature time series. It’s the time series that tells us how much the Earth has warmed. It’s the time series the IPCC uses to “verify” its climate models and to support its claim that the warming was dominantly anthropogenic. Continue reading

The Methane Time Bomb

Atmospheric methane peaks from sampling stations at Barrow northern Alaska and Alert northern Canada (off N Greenland) are centred on January of each annual cycle (Figures 1 and 4). This makes it highly unlikely that the annual cycle in methane concentrations is caused by the freeze thaw cycle of Arctic tundra. Continue reading

The High Cost of Renewables

In this post I present “back of envelope” style calculations on the capital costs of renewables globally since 1998 and deduce that roughly $1.3 trillion has been spent installing wind turbines and solar panels. Is this a lot of money? Is it a wise investment? What else may we have we got for our money?

One perspective is that the same money would buy 50 Hinkley Point style pressurised water reactors. Continue reading

The Arctic Sea Ice Canary Refuses to Die

In late 2007 the Arctic sea ice area took an unexpected plunge and this event is largely responsible for triggering the Global Warming hysteria of recent years. This led leading warmist James Hansen to declare that man made global warming … Continue reading

The residence time of CO2 in the atmosphere is …. 33 years?

By Roger Andrews An important consideration in estimating future greenhouse warming risks is how long CO2 remains in the atmosphere. Here I present the results of a simple mass balance model that provides a near-perfect fit between CO2 emissions and … Continue reading

The Arguments for and Against Shale Oil and Gas Developments

The energy debate is full of controversy. Whether it is about the pros and cons of renewable energy, nuclear power or fossil fuels (FF) there are a range of arguments made on either side. If it was clear cut which arguments were best, there would be no controversy to discuss. And so it is the case with shale developments, some strongly in favour, some violently opposed. How are we going to solve our energy crisis? Continue reading
