Volcanoes display the awesome power of Nature like few other events. Earlier this year, ash from an Icelandic volcano disrupted air travel throughout much of northern Europe. Yet this recent eruption pales next to the fury of Jupiter’s moon Io…
There may be better ways to engineer the planet’s climate to prevent dangerous global warming than mimicking volcanoes, a University of Calgary climate scientist says in two new studies.
“Releasing engineered nano-sized disks, or sulphuric acid in…
For the first time, scientists have incorporated multiple human and natural factors into a climate projection model. They predict that increased carbon dioxide in the atmosphere, due to changes in the carbon cycle, combined with a decrease in human-produced sulphates, may cause accelerated global warming during the 21st century, as compared with simulations without these feedback effects.
Missing: around 7 billion tons of carbon dioxide (CO2), the main greenhouse gas charged with global warming. Every year, industry releases about 22 billion tons of carbon dioxide into the atmosphere. And every year, when scientists measure the rise of carbon dioxide in the atmosphere, it doesn?t add up ? about half goes missing. Figuring in the amount that could be soaked up by oceans, some 7 billion tons still remain unaccounted for. Now, a study conducted at the edge of Israel?s Negev Desert has come up with what might be a piece of the puzzle.
