What if We Skip Wrecking the World Economy and Jump to Fixing the Atmosphere?

What if we could stop temperature rise and roll back world temperatures as needed? What if we could fix the atmosphere without wrecking the economy but just added a profitable business? Do we have to completely change energy, transportation and the economy BEFORE the effects of climate change are very large and clear? Do we …

Why is Geoengineered Cooling Bad and Untested if We Have Been Doing it With Sulfur Dioxide Air Pollution for Decades?

A report in Nature says that China’s sulfur dioxide air pollution has been geoengineering earth cooling by up to 0.7 degrees celsius for decades. China reduced sulfur dioxide emissions from its power plants by 7–14% between 2014 and 2016. Mainstream climate models had expected China’s air pollution to increase. Lower pollution is better for crops …

100 Special Planes and $2.5 Billion per year for Sulphate Geoengineering

Researchers reviewed all lofting technologies that seem plausible as methods to put 100,000 tons per year of sulphur to an altitude of up to ~20 km in 2033. The program then scales to 5 million tons per year. Their main research involved engaging directly with commercial aerospace vendors to elicit what current and near-term technology …

Climate Doomer claims only option is to get rid of all fossil fuels

Mayer Hillman is a climate doomer. His April 26, 2018 article in the Guardian UK is titled ‘We’re doomed’: Mayer Hillman on the climate reality no one else will dare mention. Hillman is an 86-year-old social scientist. He is a British architect and town planner. An old architect has no ideas for how to address …

Funding and research on geoengineering and climate change mitigation

Geoengineering refers to a set of emerging technologies that could manipulate the environment and partially offset some of the impacts of climate change. Solar geoengineering in particular could not be a replacement for reducing emissions (mitigation) or coping with a changing climate (adaptation); yet, it could supplement these efforts. 29 philanthropists pledged $4 billion over …

Nuclear power and geoengineering are needed for climate solution

The UN has said the world needs to cut as much as 70% of greenhouse-gas emissions by mid-century to have any chance of avoiding 2 ˚C of warming. More than half of the carbon dioxide emissions currently in the atmosphere will still be there 1,000 years from now—and roughly one-third will still be there in …

Point of no return for climate action is point when Geoengineering will start

Cumulative CO2 emissions from 2015 onwards may not exceed 424 billion tons of carbon and that the point of no return (PNR) is 2035 for the policy scenario where the share of renewable and nuclear energy rises by 2% per year. If the risk tolerance is 67% chance of exceeding the-2 degree increase. If renewables …

A walls and dams will delay major sea level rise for a few centuries and cost 1000 times less

Princeton researchers recommend targeted geoengineering to preserve continental ice sheets. “Geoengineering interventions can be targeted at specific negative consequences of climate change, rather than at the entire planet,” postdoctoral research associate in Atmospheric and Oceanic Sciences Michael Wolovick said. The ice sheets of Greenland and Antarctica will contribute more to sea-level rise this century than …

Was there global warming in the 1880s? Because 25 hurricanes hit the USA in that decade

A total of 293 Atlantic tropical cyclones have produced hurricane-force winds in every state along the Atlantic Ocean and Gulf of Mexico, as well as Pennsylvania. Florida more than any other hurricane. CNN and Jeffrey Sachs are blaming the three hurricanes that hit the USA this year on climate change. The 1880s were the most …

Modifying natural gas generation to produce lime to reverse climate change

Could we cure climate change? Geoengineering researcher Tim Kruger wants to try. He shares one promising possibility: using natural gas to generate electricity in a way that takes carbon dioxide out of the air. Learn more — both the potential and the risks — about this controversial field that seeks creative, deliberate and large-scale intervention …
