The nine boundaries we must not cross or we may go extinct
Preface. This post has excerpts from the famous paper by Rockström et al (2009) as well as a more recent proposal by Running (2012) on an easier measure of how close we’re coming to rendering the planet uninhabitable. The media … Continue reading

Jellyfish in the news
Preface. As we overfish, eutrophy and acidify the ocean with fertilizer and pesticides we risk a tipping point where jellyfish dominate the oceans and fish are scarce. Related: Why and how Jellyfish are taking over the world Alice Friedemann www.energyskeptic.com … Continue reading

Note: Peak fish happened in 1996 at 130 million tonnes a year. Pauly D, Zeller D (2016) Catch reconstructions reveal that global marine fisheries catches are higher than reported and declining. Nature communications. Preface. This is a book review of … Continue reading

Largest oil spill on earth: Plastics
Preface. There have been thousands of articles since I published this back in 2003. Today I read a surprising study that claims glass is more harmful than plastic because it is mined from rare materials and requires more fossil fuels … Continue reading
Not enough fossil fuels left to trigger another mass extinction
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
Global Ice melting
Preface. As the Arctic ice melt accelerates due to climate change it could release more than 1 trillion pieces of plastic into the ocean over the next decade, possibly posing a major threat to marine life (Lewis 2014). The rate … Continue reading

Climate Change dominates news coverage at expense of other existential planetary boundaries
Preface. In the half dozen science magazines and newspapers I get, almost the only environmental stories are about climate change. Yet there are 8 other ecological boundaries (Rockström 2009) we must not cross (shown in bold with an asterisk below) … Continue reading
World’s Oceans are losing Oxygen rapidly
Preface. Yikes, add deoxygenization to your list of worries. Oxygen levels in the world’s oceans declined by roughly 2% from 1960 and 2010. The decline was largely due to climate change, though other human activities such as nutrient runoff from … Continue reading

Why and how Jellyfish are taking over the world
Preface. The more climate change kicks in, the more we over-fish, pollute, acidify and warm the ocean, create vast dead zones, and trawl ocean bottoms, the better the jellyfish do. It is quite possible that the ocean ecosystem will shift … Continue reading

Deep-sea trawling harms biodiversity and carbon storage
Preface. Overfishing has eliminated 90% of the world’s large predatory fishes and is devastating marine ecosystems. Bottom trawling is one of the most devastating ways our oceans are being overfished, degraded and biodiversity destroyed . This industry tossed 437 million … Continue reading
