Geologist Ian Plimer: Earth has undergone dramatic climate shifts long before humans existed
02/07/2025 / By Arsenio Toledo
Geologist Ian Plimer’s book “Heaven and Earth: Global Warming – the Missing Science” challenges the prevailing scientific consensus on climate change, arguing that it is a natural, cyclical phenomenon driven by geological and solar forces rather than human-produced carbon dioxide emissions.
Plimer contends that the Earth’s climate has undergone dramatic shifts long before human existence, including ice ages and warmer interglacial periods, and that current discussions about climate change disproportionately focus on human activities.
He argues that carbon dioxide (CO2) is not the primary driver of climate change, asserting instead that the Sun is the dominant force shaping Earth’s climate. Plimer also disputes the widely accepted view that human emissions of CO2 are the main cause of global warming.
The book criticizes the Intergovernmental Panel on Climate Change (IPCC) for prioritizing politics over science, and argues that the IPCC’s computer models oversimplify the Earth’s complex systems, failing to account for geological, oceanic and cosmic processes.
Plimer’s work has sparked intense discussion among scientists, policymakers and the public, urging a deeper look into the planet’s geological past to better understand its present and future, and challenging the prevailing narrative on climate change.
