When wood is again our main energy source, how long will it last?

Preface.  Just when civilization is decades from returning to wood as the main energy source (due to peak oil in 2018), climate change is allowing invasive beetles to survive winters and kill trees, with drought and wildfires increasing the damage. … Continue reading

Carbon capture could require 25% of all global energy

Preface.  This is clearly a pipedream. Surely the authors know this, since they say that the energy needed to run direct air capture machines in 2100 is up to 300 exajoules each year. That’s more than half of global energy … Continue reading

Microbes a key factor in climate change

Preface. The IPCC, like economists, assumes our economy and burning of fossil fuels will grow exponentially until 2100 and beyond, with no limits to growth. But conventional oil peaked and has stayed on a plateau since 2005, so clearly peak … Continue reading

Climate change risks could cause an American “Fukushima”

Preface. Nuclear power plants need a constant supply of electric power to pump cool water into a reactor’s core. Ninety percent of them, 54 plants, have at least one flood risk exceeding their design. If flooding stops the power supply … Continue reading

Ice ages may be caused by mountains rising in the tropics

Preface.  In case you’d forgotten– given all the talk about climate change — we’re still in an ice age that’s been going on for 2.6 million years.  Lucky for us, we’ve been in one of the few warm periods for … Continue reading

Groundwater rise. Yet another climate change threat.

Preface. In coastal areas flooding is likely to be caused from groundwater rise because as sea levels rise, they won’t only move inland, flooding low-lying land near the shore; but also push water up from the saltwater water table, on … Continue reading

Climate change effects on hydropower in California

Preface. Climate change will impact California agriculture without the snow melt that allows for up to three crops to be grown a year, perhaps just one crop in the future. Not to mention the impact on the 40 million people … Continue reading

Hydropower dams and the ways they destroy the environment

Preface. Hydropower comprises 71% of renewable energy worldwide.  Nations like the U.S. and Europe have dams that have reached the end of their lifespan — more are being torn down than built. In the U.S. 546 dams were removed between … Continue reading

Lakes run dry from too much water extraction and climate change

Preface.   I think that declining oil will be the main cause of civilization to collapse, since it is the energy that makes all other activities possible, but there are so many other contenders I wonder if scholars in the future … Continue reading
