Climeworks’ Mammoth plant in Iceland, which began operations in May 2024. The plant removes carbon dioxide with direct air capture — one of the methods examined in APS’ latest report. Topics: Applied Physics, Climate Change, Global Warming, Green Tech Anthropologists believe our ancestors first used fire as a tool nearly two million years ago. Eventually,Continue reading “Capturing Carbon…”

Carbon Storage…
Keeping the carbon: Biochar can be added to cement to sequester carbon within concrete. (Courtesy: Sabbie Miller) Topics: Biomass, Civil Engineering, Environment, Global Warming, Green Tech Replacing conventional building materials with alternatives that sequester carbon dioxide could allow the world to lock away up to half the CO2 generated by humans each year – about 16Continue reading “Carbon Storage…”

Hummocks of moss cover Ardley Island off the tip of the Antarctic Peninsula. Credit: Dan Charman Topics: Antarctica, Civilization, Climate Change, Existentialism, Global Warming A fast-warming region of Antarctica is getting greener with shocking speed. Satellite imagery of the region reveals that the area covered by plants increased by almost 14 times over 35 years — aContinue reading “Antarctic Greenbelt…”

Meinzahn/Getty Images Topics: Applied Physics, Atmospheric Science, Chemistry, Climate Change, Global Warming Note: It’s disheartening that geoengineering, made popular by science fiction novels and plots in Star Trek, is being considered because we’re too selfish to change our behavior. More and more climate scientists are supporting experiments to cool Earth by altering the stratosphere orContinue reading “Driven to Caveat Emptor…”

The Flood by Antonio Marziale Carracci Topics: Civilization, Climate Change, Energy, Environment, Existentialism, Global Warming Another week, another catastrophic, record-setting, history-making flood, this time in Kentucky. Preliminary assessments indicate rainfall in Graves County last week likely set a new record for most precipitation in a 24-hour period, with 11.28 inches of rain. This would make it yetContinue reading “Everything, Everywhere, All at Once…”
