Cool heads and hot claims

Dr Willem de Lange, a senior lecturer in Waikato University’s Department of Earth and Ocean Sciences, explains why he’s a sceptic:

In 1996 the United Nations Intergovernmental Panel on Climate Change’s (IPCC) Second Assessment Report was released, and I was listed as one of approximately 3000 “scientists” who agreed that there was a discernable human influence on climate.

I was an invited reviewer for a chapter dealing with the economic impact of sea level rise on small island nations… I was not asked if I supported the view expressed in my name, and my understanding at the time was that no evidence of a discernable human influence on global climate existed.

The chapter I reviewed dealt primarily with the economic consequences of an assumed sea level rise of 1 m causing extensive inundation… I disagreed with the initial assumptions, particularly the assumed sea level rise in the stated time period.

Further, there was good evidence at the time that sea level rise would not necessarily result in flooding of small island nations… Subsequent research has demonstrated that coral atolls and associated islands are likely to increase in elevation as sea level rises. Hence, the assumptions were invalid, and I was convinced that IPCC projections were unrealistic and exaggerated the problem…

What has sea level actually done so far this century? There have been large regional variations, but the global rate has slowed and is currently negative, consistent with measured ocean cooling. Claims to the contrary are exaggerations and not realistic…

Trying to stop or control climate change is akin to stopping ocean tides…. As the latest IPCC report notes, there is no convincing evidence of the impact of CO2 (or any other human influence on climate) at a continental scale…

So, I am a climate realist because the available evidence indicates that climate change is predominantly, if not entirely, natural. It occurs mostly in response to variations in solar heating of the oceans, and the consequences this has for the rest of the Earth’s climate system. There is no evidence to support the hypothesis runaway catastrophic climate change due to human activities.

Contrast that to the CSIRO’s most recent alarmism:

The number of extreme fire days in Victoria will skyrocket by up to 230 per cent in the next 40 years, prompting calls for a catastrophic level of alert, a climate change report warns.

The Victorian government’s green paper on climate change, launched on Wednesday, also warns of job losses and a hefty increase in the cost of living. The report predicts average temperatures to rise by more than three per cent on 1990 levels by 2070…

It also warned of infrastructure in coastal areas becoming inundated by rising sea levels and of a tourism downturn at the state’s ski resorts because of soaring temperatures.

Seems the CSIRO is sticking to its scares despite bumming out in scare-claims on vanishing snow and empty dams.
