Climate science key to survivable planet

Global R&D expenditure $1.8 trillion, US climate research peaked 1995 at $2.4 billion

Last call for climate action commission

Dr Jan Wright’s last report is also her least likely to ruffle feathers. Until now, the Parliamentary Commissioner for the Environment’s refreshingly evidence-based reports have probably unsettled more Green Party supporters than the balance of…

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…

Renewable energy, nuclear power and Galileo

Climate scientists have long warned of potential catastrophic effects of unchecked fossil fuel use. Public awareness of the climate threat has increased. Yet growth of carbon dioxide in the air, the main driver of climate change, has accelerated…

Manifest evidence suggests science not an option

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 Zealanders will be inclined to give the book a second glance than would otherwise have been the…

CO2 psychology not rocket science

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…

Anthropocene ensures Holocene has had its day

Geology was one of Ronald Locker’s abiding passions. 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…

co2 can come before and after warming

It’s a perfectly reasonable 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…

Preventing climate confusion raining

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 additional job, as a subeditor for Fairfax Media. Taking up a new job at 61 years has proved to be both exhilarating and…
