Read this! putting the climate emergency in context

This 50th Anniversary interview with a “Limits to Growth” author puts the work in context and shows more to do than just stopping warming

by Richard Heinberg & Dennis Meadows, 22/02/2022 in Resilience.org
Dennis Meadows on the 50th anniversary of the publication of The Limits to Growth: Only rarely does a book truly change the world. In the nineteenth century, such a book was Charles Darwin’s On the Origin of Species. For the twentieth century, it was The Limits to Growth. Not only did this best-selling 1972 publication help spur the environmental movement, but it showed that the underlying dynamics of the modern industrial world are unsustainable on the timescale of a couple of human lifetimes.

IPCC’s 28 Feb climate change report will be bad news

William P. Hall on February 24, 2022

Part 2 of AR6 – The IPCC’s report on climate change impacts will likely be bad enough. However the actual truth will probably be even worse

by Matt McGrath, 22/02/2022 in BBC News/Science
IPCC: Climate change report to sound warning on impacts

A new report on the impacts of climate change will likely be the most worrying assessment yet of how rising temperatures affect every living thing.

What do you fix first? Methane or CO₂?

William P. Hall on February 24, 2022

Methane is more powerful than CO₂ but has a relatively short life in the atmosphere. CO₂ hangs around for centuries. Both are bad news!

by John Lynch, 21/02/2022 in The Bulletin of the Atomic Scientists
Fatal distraction: the problem with the methane pledge

Over the past year, the world has experienced severe heatwaves, wildfires, and drought. As global temperature continues to creep upwards, these events will become more frequent and more extreme. Obviously, humanity needs to make a concerted effort to rapidly bring down greenhouse gas emissions to limit warming to 1.5-2 degrees Celsius above pre-industrial levels, as global leaders agreed to do when they signed the Paris Agreement.

Offshore wind generation set to grow fast in USA

William P. Hall on February 23, 2022

Projects in pipeline promise more than Biden’s 30 GW by 2030, but struggle for financing. Why can’t govt. provide it in climate emergency?

by Emma Penrod, 17/02/2022 in UTILITYDIVE
Offshore wind on track to hit, possibly exceed Biden’s 30 GW target by 2030

Two independent analyses completed this month have determined that the U.S. is now on track to deploy at least 30 GW of offshore wind generation by 2030, meeting a key goal established by the Biden administration.

What will it cost the world to achieve net zero by 2050?

William P. Hall on February 23, 2022

Following on from Estimating the social cost of [uncontrolled] greenhouse gas pollution, what is the likely cost to shut down the emissions?

by David Brancaccio and Rose Conlon 14/02/2022 in Marketplace
What would it take to reach net-zero global emissions by 2050?:

More than 70 countries have pledged to cut their greenhouse gas emissions to net zero by mid-century. And in order to achieve the Paris Agreement’s goal of limiting global warming to 1.5 degrees Celsius above pre-industrial levels, the Intergovernmental Panel on Climate Change projects the world would need to reach net-zero emissions by 2050. Such a transition would require colossal change throughout the global economy, according to a new report from the McKinsey Global Institute, citing an average of $9.2 trillion in annual spending on physical infrastructure through 2050— $3.5 trillion more than current yearly spending.

Cheap H₂ storage may dispatch power for months

William P. Hall on February 18, 2022

Hydrogen gas stored for less than $3/kg may provide months of dispatchable power to cover intermittent green energy generation

by Emiliano Bellini, 14/02/2022 in PV Magazine

Hydrogen under $3/kg may ensure affordable seasonal energy storage in the US

Researchers from the United States have investigated how fuel cells and electrolyzers may be able to operate under intermittent availability provided by both wind and solar and have found that an affordable hydrogen-based system for seasonal energy storage could be achieved at a hydrogen price lower than $3, produced from inexpensive renewable electricity at $0.02/kWh.
