By Raymond Pierrehumbert 16 August 2019 (Bulletin of the Atomic Scientists) – Let’s get this on the table right away, without mincing words. With regard to the climate crisis, yes, it’s time to panic. We are in deep trouble. To understand why, it is necessary to understand something about carbon budgets. Some of the carbon […]
By Katherine J. Wu 17 July 2019 (PBS) – Gird your loins, humans: The time has come to turn part of the South Pole into our own giant snow globe. Or has it? In a study published today in the journal Science Advances, a team of German researchers suggests that dumping 8 trillion tons of artificial snow onto […]
By Stuart Leavenworth 8 November 2017 WASHINGTON (McClatchy) – Ever-higher temperatures are melting the ice sheets faster than projected. Sea level is rising. International efforts to reduce greenhouse gases are taking longer than expected. It’s a nightmare scenario that could soon demand an emergency response. What to do? One idea gaining traction is to seed […]
By Kate Connolly 14 October 201 (The Guardian) – Leading climate scientists have warned that geoengineering research could be hijacked by climate change deniers as an excuse not to reduce CO2 emissions, citing the US administration under Donald Trump as a major threat to their work.David Keith, a solar geoengineering (GE) expert at Harvard University […]
By Fiona Macrae, Science Correspondent 15 February 2015 San Jose (Daily Mail) – If it seems like it never stops raining, blame the Russians. Or even the North Koreans. CIA chiefs fear hostile nations are trying to manipulate the world’s weather, a conference heard. A leading academic has told how he got a mysterious phone […]
By Raymond T. Pierrehumbert10 February 2015 (Slate) – Some years ago, in the question-and-answer session after a lecture at the American Geophysical Union, I described certain geoengineering proposals as “barking mad.” The remark went rather viral in the geoengineering community. The climate-hacking proposals I was referring to were schemes that attempt to cancel out some […]
There is a great difference between being still and doing nothing. ~Chinese proverb~ By Carolyn Baker16 April, 2014 (Carolynbaker.net) – When I speak about catastrophic climate change and the likelihood of near-term human extinction, I am often accused to “giving up” or choosing to “do nothing” about climate change. Even more charged for some is […]
27 September 2013 (IPCC) – Global mean surface temperature increase as a function of cumulative total global CO2 emissions from various lines of evidence. Multi-model results from a hierarchy of climate-carbon cycle models for each RCP until 2100 are shown with coloured lines and decadal means (dots). Some decadal means are indicated for clarity (e.g., […]
By David Suzuki3 September 2013 (DeSmogBlog.com) – I recently wrote about geoengineering as a strategy to deal with climate change and carbon dioxide emissions. That drew comments from people who confuse this scientific process with the unscientific theory of “chemtrails”. Some also claimed the column supported geoengineering, which it didn’t. The reaction got me wondering […]
By Alister Doyle; Editing by Simon Robinson and Sara Ledwith30 August 2013 (Reuters) – Last year the Haida, an indigenous group in Canada, set out to increase their salmon stocks and save the planet. Helped by American businessman Russ George, a group of villagers dumped 100 metric tons (110.23 tons) of iron dust from a […]
