There was debate last week when Peter Williams claimed the science on climate change wasn’t settled.
Turns out he’s wrong, the science behind the climate crisis IS settled…
The speed and extent of current global warming exceeds any similar event in the past 2,000 years, researchers say.
They show that famous historic events like the “Little Ice Age” don’t compare with the scale of warming seen over the last century.
The research suggests that the current warming rate is higher than any observed previously.
The scientists say it shows many of the arguments used by climate sceptics are no longer valid.
When scientists have surveyed the climactic history of our world over the past centuries a number of key eras have stood out.
These ranged from the “Roman Warm Period”, which ran from AD 250 to AD 400, and saw unusually warm weather across Europe, to the famed Little Ice Age, which saw temperatures drop for centuries from the 1300s.
The events were seen by some as evidence that the world has warmed and cooled many times over the centuries and that the warming seen in the world since the industrial revolution was part of that pattern and therefore nothing to be alarmed about.
Three new research papers show that argument is on shaky ground.
The science teams reconstructed the climate conditions that existed over the past 2,000 years using 700 proxy records of temperature changes, including tree rings, corals and lake sediments. They determined that none of these climate events occurred on a global scale.
The researchers say that, for example, the Little Ice Age was at its strongest in the Pacific Ocean in the 15th Century, while in Europe it was the 17th Century.
Generally, any longer-term peaks or troughs in temperature could be detected in no more than half the globe at any one time,
The “Medieval Warm Period”, which ran between AD 950 and AD 1250 only saw significant temperature rises across 40% of the Earth’s surface.
Today’s warming, by contrast, impacts the vast majority of the world.
“We find that the warmest period of the past two millennia occurred during the 20th Century for more than 98% of the globe,” one of the papers states.
“This provides strong evidence that anthropogenic (human induced) global warming is not only unparalleled in terms of absolute temperatures but also unprecedented in spatial consistency within the context of the past 2,000 years.”
…let’s take a wee gander at that chart…
…well, well, well, that charts looks a tad concerning doesn’t it folks?
For those claiming the climate always changes and it has nothing to do with human pollution – the time for denial is over the time for real political leadership is now. The truth is that the climate crisis stopped being about science a long time ago, this is a culture war now.
Those who have benefitted from the privileges of big polluting capitalism refuse to agree that the environmentalists have been right all along, even if it means cooking themselves and the planet.
Climate deniers and middle class minimisers are still the battlefront. Radical solutions are rapidly becoming the only solution.
To survive climate change we must embark upon Fortress Aotearoa…

- Massive investment into R&D from Government with the understanding research is to benefit NZ first before sold offshore.
- Large scale increase in Navy, Army & Airforce.
- Mass limiting of tourism numbers with increased tourist taxes.
- Only citizens can vote.
- Sustainable immigration and an end to exploitative migrant workers.
- Resettlement Programms for all pacific island neighbours.
