Rock dust on fields could remove vast amounts of CO2

The Guardian / Damian Carrington / 8 July 2020

Spreading rock dust on farmland could suck billions of tonnes of carbon dioxide from the air every year, according to the first detailed global analysis of the technique.

The chemical reactions that degrade the rock particles lock the greenhouse gas into carbonates within months, and some scientists say this approach may be the best near-term way of removing CO2 from the atmosphere.

The researchers are clear that cutting the fossil fuel burning that releases CO2 is the most important action needed to tackle the climate emergency. But climate scientists also agree that, in addition, massive amounts of CO2 need to be removed from the air to meet the Paris agreement goals of keeping global temperature rise below 2C.

Coronavirus, climate change: Dealing with converging crises

Bulletin of the Atomic Scientists / Dawn Stover / 8 July 2020

Like climate change, the pandemic seemed distant and unreal until it was already upon us. Now both urgently require a society-wide response. Scientists have offered clear recommendations about how to solve these problems. However, the coronavirus won’t subside without broad social cooperation on behaviors such as physical distancing, mask wearing, and hand washing—an expanded version of the neighborly help that solved my electrical problem.

Similarly, the climate won’t heal without a new “healthcare system” for the planet that has strong support from the general public. It shouldn’t take another year of killer heat waves, mega-fires, and other disasters to convince Americans that we’ll never get back to “normal” by ignoring what’s happening around us.

IEA summit on global green recovery from Covid-19 crisis

The Guardian / Fiona Harvey / 29 June 2020

Key to success will be that governments can sign up to green recovery plans even if – like the US – they are sceptical on the climate crisis, said Fatih Birol, the executive director of the IEA. “Even if governments do not take climate change as a key priority, they should still implement our sustainable recovery plan just to create jobs and to give economic growth. Renovating buildings, for instance, is a job machine.”

Birol fears a rerun of the recovery after the financial crisis of 2008, when emissions declined sharply in the recession but quickly returned to levels much higher than before, as governments invested in coal-fired power plants, constructed inefficient buildings, and rolled out road-building schemes.

IEA: ‘Green’ recovery would keep emissions below 2019 peak

Carbon Brief / Josh Gabbatiss / 18 June 2020

The world has a “once-in-a-lifetime opportunity” to pour investment into clean energy and create millions of new jobs, according to the International Energy Agency (IEA).

Its “sustainable recovery plan” for the coronavirus pandemic lays out a series of measures that the agency says would ensure 2019 was the “definitive peak” for global emissions.

Launched in cooperation with the International Monetary Fund (IMF), the new report presents a strategy for economic growth that includes mass home renovations, fossil-fuel subsidy reforms, renewables and the expansion of power grids.

More extreme rainfall due to climate change, study confirms

CBC News / Emily Chung, Alice Hopton, Tashauna Reid / 03 June 2020

Warmer temperatures due to climate change lead to wetter air, and we’ve seen more extreme rainfall and flooding across North America. But is there really evidence that the two are related?

Yes, there is.

A new study from researchers at Environment and Climate Change Canada found that climate change has made:

  • Rainfall more extreme.
  • Storms with extreme rainfall more frequent.

Canadians still support climate action: poll

BIV / Jeremy Hainsworth / 28 May 2020

COVID-19’s economic and health challenges have not diminished support for infrastructure changes to create a cleaner Canadian economy, a new poll finds.

Results from the Abacus Data-Clean Energy Canada poll released May 28 found an equal number of those surveyed believed a change to a cleaner economy was possible and that such considerations should come after health and economic concerns.

The Transition Framework

Resilience is the ability of a system or community to withstand impacts from outside. An indicator is a good way of measuring that. Conventionally, the principal way of measuring a reducing carbon footprint is CO2 emissions. However, we firmly believe that cutting carbon while failing to build resilience is an insufficient response when you’re trying to address multiple shocks such as peak oil, climate change and the economic crisis together.
