Not enough fossil fuels left to trigger another mass extinction

Posted on September 11, 2021 by

Preface. Since both conventional and unconventional oil peaked in 2018, we clearly won’t be burning fossils at exponentially increasing rates until 2400 as the IPCC expected. Quite the opposite, currently the decline rate of oil is 8% a year, which … Continue reading →

Why we aren’t mining methane hydrates now — or perhaps ever

Posted on June 10, 2021 by

Preface. Methane hydrates are far from being commercial, and probably always will be. Scientists and companies have been trying to exploit them since the first energy crisis in 1973 to no avail. Nor are they likely to trigger a runaway … Continue reading →
