• 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.

In a world increasingly defined by urgent calls to address climate change, geologist Ian Plimer's book "Heaven and Earth: Global Warming – the Missing Science" has reignited debates about humanity's role in shaping the planet's climate. Published in 2009, the book argues that climate change is a natural, cyclical phenomenon driven by geological and solar forces, rather than primarily by human-produced carbon dioxide emissions. Plimer, a professor of geology and mining geology at the University of Adelaide in South Australia, challenges the scientific consensus underpinning global climate policy, particularly the work of the Intergovernmental Panel on Climate Change (IPCC). His claims have sparked intense discussion among scientists, policymakers and the public, raising questions about the balance between natural variability and human influence on Earth’s climate. Plimer's central thesis is rooted in geology, a discipline he argues provides a holistic understanding of Earth’s climate history. He contends that the planet has undergone dramatic climate shifts long before humans existed, from ice ages to warmer interglacial periods. He points out that the Earth is currently in an ice age that began 37 million years ago, punctuated by warmer intervals that have allowed life and civilizations to flourish. This perspective, he argues, is often overlooked in contemporary discussions about climate change, which he believes disproportionately focus on human activities. One of Plimer's most provocative claims is that carbon dioxide (CO2) is not the primary driver of climate change. He asserts that the Sun, not CO2, is the dominant force shaping Earth’s climate. Plimer further challenges the widely accepted view that human emissions of CO2 are the main cause of global warming, arguing that atmospheric CO2 levels have been far higher in the past without catastrophic consequences. He also notes that CO2 levels often follow temperature increases, rather than causing them, a point he says undermines the argument that human-produced CO2 is forcing current warming. Plimer is particularly critical of the computer models used by the IPCC to predict future climate scenarios. He argues that these models oversimplify the Earth’s complex systems, failing to account for geological, oceanic and cosmic processes. By reducing modern climate change to just one variable – the levels of CO2 in the atmosphere – Plimer argues the IPCC is being very unscientific. He is calling for a more nuanced understanding of climate change, one that incorporates the planet’s long history of natural variability. The book also takes aim at the IPCC itself, which Plimer accuses of prioritizing politics over science. He argues that the IPCC’s Summary for Policymakers, a widely cited document, is not subject to rigorous peer review and reflects political agendas rather than scientific consensus. Plimer further disputes claims that the scientific community is overwhelmingly certain about human-induced global warming, calling such assertions “a figure of speech” without empirical basis. Plimer's work has drawn both praise and criticism. Supporters applaud his emphasis on geological history and his challenge to what they see as an overreliance on CO2 as the primary climate driver. As governments and organizations worldwide push for aggressive action to reduce emissions, voices like Plimer’s serve as a reminder of the complexities and uncertainties inherent in climate science. Whether one agrees with his conclusions or not, "Heaven and Earth" forces readers to grapple with fundamental questions about the Earth’s climate system and humanity’s place within it. In an era defined by climate anxiety and policy urgency, Plimer's work challenges the prevailing narrative, urging a deeper look into the planet’s geological past to better understand its present and future. As the world continues to debate how best to address climate change, Heaven and Earth remains a provocative contribution to the conversation, one that demands attention even as it divides opinion.
