Geoengineering could alter global climate. Should It?

Salon

In April, in the Bay Area town of Alameda, scientists were making plans to block the sun. “Geoengineering doesn’t tackle the root causes of climate change; it’s arranged to counter some of the impacts, but it involves intervening in Earth’s systems at an absolutely enormous scale,” said Mary Church, the geoengineering campaign manager for the Fossil Economy program at the …

Diamond Dust: A Promising Solution to Fight Climate Change?

Firstpost

Scientists propose spraying $200 trillion worth of diamond dust into the atmosphere to fight climate change. The diamond dust would be dispersed to reflect sunlight and cool the planet by nearly 2.9 degrees Fahrenheit. However, the cost of this solution is staggering, making it more of a thought experiment than a practical plan. While diamond dust performs exceptionally well in …

Politicization of research not good climate action

China Daily

LI MIN/CHINA DAILY Climate studies are increasingly becoming politicized. Harvard University recently shut down a key geo-engineering research project because of an intense backlash, despite the college's aspiration to become "a global beacon on climate change". As the world has so far mostly failed to tackle climate change by reducing fossil fuel reliance, it seems prudent to also investigate other …

Should we geoengineer volcanoes?

BBC

Should we geoengineer volcanoes? It's one of various example where "geoengineering" a volcano could save lives and prevent catastrophe. However, it's clear that volcano geoengineering could save many lives, if it could be done safely. And as the video below shows, there's one in New Zealand too: WATCH: New Zealand's long overdue supervolcano Geoengineering could also mitigate wider catastrophic effects. …

Can solar geoengineering stop global warming?

The Hindu

As the world struggles to renounce its burning of fossil fuels, scientists are studying whether atmospheric geoengineering could help limit warming and avert climate catastrophe. Efforts to banish SO2 as a harmful air pollutant in China and elsewhere over the last decade have dampened its cooling effect and "unmasked" heat caused by greenhouse gases, thereby contributing to rising global temperatures. …

To avert climate disaster, what if one rogue nation dimmed the Sun?

BBC

To avert climate disaster, what if one rogue nation dimmed the Sun? The contentious move flies in the face of international law, as the book imagines it, and risks disrupting monsoon rains – but it also reduces global temperatures by "one degree, for three years". Stratospheric aerosol injection would require "a fleet of several hundred large high-altitude jets of a …

Geoengineering is not a quick climate fix, but a costly gamble

The Hindu

When soaring temperatures, extreme weather and catastrophic wildfires hit the headlines, people start asking for quick fixes to climate change. Geoengineering, theoretically, aims to restore that balance, either by removing excess carbon dioxide from the atmosphere or reflecting solar energy away from Earth. Some scientists have suggested going further and installing arrays of space mirrors that could reduce global temperature …

The European Commission on Wednesday called for international talks on the dangers and governance of geoengineering, saying such interventions to alter the climate posed "unacceptable" risks. Geoengineering has attracted increasing interest as countries fail to cut greenhouse gas emissions fast enough to curb climate change. "Nobody should be conducting experiments alone with our shared planet," European Union climate policy chief …

Geoengineering means manipulating the earth’s climate to lower its temperature in a bid to counter global warming. Solar geoengineering, also called solar radiation modification, involves cooling the earth by radiating absorbed sunlight back into space. The basic idea behind solar geoengineering The temperature of the earth’s surface rises by absorbing heat energy from the sun. Types of solar geoengineering Currently, …

CNN — When US startup Make Sunsets released two weather balloons into the skies above Mexico’s Baja California peninsula last year, it kicked up a fierce debate about one of the world’s most controversial climate solutions. While pretty much no one is claiming solar geoengineering could replace planet-warming pollution cuts and solve climate change, supporters argue it could have a …

There is no law or treaty to prevent a private company from tinkering with geo-engineering—say, releasing sulphur dioxide high in the stratosphere to alter the climate. The US Clean Air Act isn’t set up to deal with this sort of thing—it’s focused on power plants, cars and regional air-quality standards, said UCLA environmental law professor Edward Parson. They’d make money …
