"The Northern Hemisphere is warming much faster than the Southern Hemisphere due to structural geographic and oceanographic factors. Investors should work within the consensus climate framework rather than fighting it, focusing closely on structural threats to the insurance, agricultural, and power sectors."
In the October 2025 Absolute Return Letter, Niels C. Jensen examines the core physical drivers of climate change outside of human behavior, highlighting that the Northern Hemisphere (NH) is warming significantly faster than the Southern Hemisphere (SH). He details five structural reasons for this discrepancy: higher landmass in the NH, Arctic albedo feedback loops, Southern Ocean heat absorption acting as a thermal buffer, northward ocean heat transport, and historically concentrated NH industrial aerosol emissions. The letter details the demographic and economic implications of this asymmetry, noting that the vast majority of the global population resides in the more vulnerable NH. From an investment perspective, Jensen argues that trying to bet against the political and social consensus on human-blamed climate change is futile. Instead, investors must prepare for severe disruptions across key sectors, pointing to immediate risks facing insurance companies, geographic shifts in agricultural viability, and the physical vulnerability of renewable energy grids to extreme weather. The appendix covers Milankovitch cycles, explaining that while they dictate long-term ice ages, their short-term warming impact is minor compared to greenhouse gases.
