Climate science

After 26 years of climate inaction, pull plug on IPCC

It is unstoppable, and it has possibly doubled. And while that is only the disintegration of the Western Antarctic Ice Sheet, the same is probably true for global warming generally. Three years of the most detailed satellite measurements yet, to the end of last year,... read more

Manifest evidence suggests science not an option

Everyone is entitled to their own opinions, but they are not entitled to their own facts. Daniel Patrick Moynihan 1927–2003 When Professor Sir Peter Gluckman recommends a title with such seemingly marginal appeal as The Geek Manifesto, it’s a sure bet rather more New... read more

Psychology CO2 and rocket science

At December’s Mahurangi Club I shared a few ideas around psychology, climate change, and climate change denial. As I said at the time, the psychology of climate change isn’t rocket science; it is far more complicated than that. Here I will share a bit more psychology... read more

100% pure space mission

It would cost about 7% of the planned Pūhoi–Wellsford motorway. But rather than generate more greenhouse gases and trust to luck that its ministers will never have to face an international climate court, the government could fund an urgently needed and long overdue... read more

As opposed to politician, reason to trust scientist

Every catchment issue is set to become more acute. Scientists and economists are warning us with increasing urgency of impending environmental and social calamities—damage, ozone depletion, and energy depletion caused by humanity’s excesses. Politicians seem to greet... read more

Planet is doomed but save the sea and sky

The phrase ‘save the planet’ grates for good reason. Nothing that humankind can currently throw at it, greenhouse gases included, can affect the existence of planet Earth. Even if every nuclear weapon were detonated simultaneously for good measure, the planet would... read more

Climate camps and the world’s shortest year

And the prize for the most foolish first line goes to: Climate change advocates will be buoyed by data which has emerged from the US today. Admittedly, the New Zealand Herald is not alone in using the ludicrous phrase ‘climate change advocate’. But for foolishness,... read more

Has the Holocene had its day?

Geology was one of Ronald Locker’s abiding interests. In his chapter Laying the Foundations, Jade River : A History of the Mahurangi’s author succinctly explains the processes that gave rise to the Mahurangi—how this landscape of outstanding natural beauty came to be.... read more

CO2 can come before and after

It’s a perfectly good question. If, following ice ages, a rise in carbon dioxide followed global warming, why is the scientific consensus that the current rise is causing global warming? The short answer is that increased levels of carbon dioxide can both cause, and... read more

Preventing climate confusion raining

Review The Discovery of Global Warming, Spencer R Weart Publishers: Harvard University Press (2003); American Institute of Physics (online) Regular readers will be aware that my goal of a new page published every day has gone up in CO2. The reason is that I have an... read more
