By Daniel Ross – Desperate times call for desperate measures, as the saying goes. As scientists, policymakers and politicians keep one increasingly startled eye on climate change’s ticking clock and the other on the ongoing, upwardly mobile trend in greenhouse gas emissions, it’s no wonder possible solutions that have been long dismissed as fringe slices of science fiction are making their way into the mainstream.
Enter center stage geoengineering, a hitherto black sheep of the fight against global warming.
Geoengineering is a broadly encompassing term with a few close etymological cousins—namely climate engineering and climate change mitigation—along with a sizable stable of associated technologies. Some of them, like afforestation and ocean iron fertilization, fall under the umbrella of carbon dioxide removal (CDR) in that they seek to draw down carbon dioxide from the atmosphere. But these are techniques that would in all likelihood shift the climate change needle relatively slowly.
In comparison, technologies under the rubric of solar radiation management (SRM) are expected to work on a much faster timescale, and as a consequence, generate arguably the greater buzz. Solar engineering is the idea that humankind artificially limits how much sunlight and heat are permitted in the atmosphere, and includes the thinning of high-level cirrus clouds to help infrared rays more easily escape upward, along with the brightening of low-level marine clouds to help reflect sunlight back into space. more>
By Harry Bowcott, Lori Fomenko, Alastair Hamilton, Mekala Krishnan, Mihir Mysore, Alexis Trittipo, and Oliver Walker – The United Nations’ 2021 Intergovernmental Panel on Climate Change (IPCC) report stated—with higher confidence than ever before—that, without meaningful decarbonization, global temperatures will rise to at least 1.5°C above preindustrial levels within the next two decades.
McKinsey – Decarbonizing the world’s economy will largely be a matter of overhauling the global energy system. And the necessary changes made to policies, technology, finance, and business models will affect the way that all individuals and all institutions produce and use energy.:format(webp)/cdn.vox-cdn.com/uploads/chorus_image/image/70062455/net_emissions_board_2.0.jpg "(vox.com)")
By Umair Irfan – Corporations and countries around the world are promising to eliminate their contributions to climate change. But many of their targets for cutting greenhouse gas emissions are prefaced by a slippery phrase: “net-zero.”
By Ben Geman – A Mississippi utility is installing what’s being billed as “the world’s first large flexible transformer” — an Energy Department-backed project aimed at boosting grid resilience and smoothing integration of renewables.

By George Tyler – The European Union is leading the world in adopting limits on greenhouse-gas (GHG) emissions, notably via hefty carbon taxes. New policies always experience teething problems but an EU environmental 
By Sven Heiligtag, Katsuhiro Sato, Benjamin Sauer, and Koji Toyama – With the passage in late 2019 of a law that allows offshore turbines to operate for 30 years, Japan has begun in earnest its journey away from fossil fuels and nuclear energy.
By Tomas Kellner – Canada, like many industrialized countries, has pledged to reduce its net carbon emissions to zero by 2050. But what makes Canada unique is how it wants to achieve that goal. Like others, it has been boosting renewables like wind and solar. But it also plans to add to the mix a powerful new source: small modular reactors, or SMRs.
