New Study Challenges Climate Establishment’s Key Warming Metric

The implications could be significant.

For years, the public has been told that the science of climate change is settled.  Governments, media outlets, and international organizations frequently assert that the evidence for dangerous planetary warming is overwhelming.

Yet one of the most important measurements supporting that claim is now being challenged by new scientific research.

An international team of scientists has published a study arguing that the primary method used to estimate global ocean heat content — a central metric used in modern climate assessments — may be fundamentally flawed.  If their analysis is correct, one of the pillars supporting claims of a steadily warming planet could be far less certain than widely believed.

The implications could be significant, because ocean heat measurements play a crucial role in the conclusions reached by the United Nations’ Intergovernmental Panel on Climate Change (IPCC).

Why Ocean Heat Matters

In recent years, climate scientists have increasingly focused on the oceans when trying to determine whether the Earth is accumulating excess heat.

The reasoning is straightforward.  The oceans store vastly more heat than the atmosphere.  If the planet is truly warming due to greenhouse gases, the oceans should be absorbing much of that energy.

According to IPCC assessments, the Earth is currently accumulating energy at roughly 0.065 watts per square foot of the planet’s surface.  That number may sound small, but spread across the entire globe, it represents an enormous amount of heat.

This estimate has become a central figure in modern climate science.  It is frequently cited as evidence that the........
