Should we tweak the atmosphere to counteract global warming?
Should we tweak the atmosphere to counteract global warming? With severe climate impacts becoming more and more apparent, many scientists think we should explore ways to block out solar radiation, but doing so would be risky. Earlier this month, on the deck of a second world war aircraft carrier docked in San Francisco, a giant […]
More climate-warming methane leaks into the atmosphere than ever gets reported – here’s how satellites can find the leaks and avoid wasting a valuable resource
More climate-warming methane leaks into the atmosphere than ever gets reported – here’s how satellites can find the leaks and avoid wasting a valuable resource Far more methane, a potent greenhouse gas, is being released from landfills and oil and gas operations around the world than governments realized, recent airborne and satellite surveys show. That’s a problem for the climate as […]
Putting the Land Back In Climate
Putting the Land Back In Climate What if we’ve been looking at the climate, well, incompletely? What if there’s another side to climate change, one less concerned with what we put in the atmosphere than what we do to the land, a side which, despite four decades of climate education, has yet to be explained […]
Weather 2022: New anomalies are growing in the Atmosphere and the Oceans, that will change the weather patterns as we head deeper into the year
Weather 2022: New anomalies are growing in the Atmosphere and the Oceans, that will change the weather patterns as we head deeper into the year Major changes are coming in 2022 across the atmosphere and the oceans, creating different weather patterns into the second half of the year, and especially in the cold season later […]
Climate explained: why carbon dioxide has such outsized influence on Earth’s climate
Climate explained: why carbon dioxide has such outsized influence on Earth’s climate I heard that carbon dioxide makes up 0.04% of the world’s atmosphere. Not 0.4% or 4%, but 0.04%! How can it be so important in global warming if it’s such a small percentage? I am often asked how carbon dioxide can have an important […]
Living in the Concretaceous Period
Living in the Concretaceous Period Scientists long ago determined that Earth had entered the Anthropocene period, based on a determination that humans were altering fundamental planetary parameters such as biodiversity and the chemistry of the atmosphere and oceans to the degree that it warranted an entirely new geological designation. Following another millennium of observation and […]
We’re in year 30 of the current climate crisis
An excerpt from the Conference Statement of the 1988 World Conference on the Changing Atmosphere held in Toronto We’re in year 30 of the current climate crisis In late-June, 1988, Canada hosted the world’s first large-scale climate conference that brought together scientists, experts, policymakers, elected officials, and the media. The “World Conference on the Changing […]
Junk Planet: Is Earth the Largest Garbage Dump in the Universe?
Junk Planet: Is Earth the Largest Garbage Dump in the Universe? Is Earth the largest garbage dump in the Universe? I don’t know. But it’s a safe bet that Earth would be a contender were such a competition to be held. Let me explain why. To start, just listing the types of rubbish generated by […]
How the World Passed a Carbon Threshold and Why It Matters
How the World Passed a Carbon Threshold and Why It Matters Last year marked the first time in several million years that atmospheric concentrations of CO2 passed 400 parts per million. By looking at what Earth’s climate was like in previous eras of high CO2 levels, scientists are getting a sobering picture of where we […]
Too Little, Too Late
Too Little, Too Late Last week, after a great deal of debate, the passengers aboard the Titanic voted to impose modest limits sometime soon on the rate at which water is pouring into the doomed ship’s hull. Despite the torrents of self-congratulatory rhetoric currently flooding into the media from the White House and an assortment of groups […]
Earth’s Second Lung Has Emphysema
Earth’s Second Lung Has Emphysema Many consider forests as the ‘lungs’ of the planet — the idea that trees and other plants take up carbon and produce oxygen (the carbon and oxygen cycles). If we are to be fair though, the oceans store about 93% of the Earth’s carbon pool (excluding the lithosphere and fossil […]
