5 cool measurement tools attempting to quantify regenerative agriculture

GreenBiz

5 cool measurement tools attempting to quantify regenerative agriculture. These new tools — under development or in the early phases of testing — are helping put numbers to the abstract concept of regenerative agriculture and helping measure metrics such as biodiversity, carbon sequestration and other soil health considerations. .

This new cooling technology also prevents viral spread. In the face of dangerous heat waves this summer, Americans have taken shelter in air-conditioned cooling centers. The same air conditioning systems that keep us cool recirculate air around us, potentially spreading the coronavirus. Gloria Oladipo. Thu, 10/08/2020 - 00:40.

Cooling a hidden threat for climate change and sustainable goals, says Oxford study

Envirotec Magazine

Past research suggests that growing international demand for cooling has the potential to drive one of the most substantial increases in greenhouse gas emissions in recent history. A new study, led by the University of Oxford and published on 19 October in Nature Sustainability , sets out a framework for delivering sustainable cooling.

Can ACs cool the world without warming it?

Grist

Several companies, including Gradient where Romanin is CEO (which landed him on the 2021 Grist 50 list ), are developing new AC technologies and approaches that are starting to show what a more efficient, less climate-intensive approach to cooling will look like. “And that absolutely doesn’t need to be true.”

CARB proposes new rules for defining EV battery health

Charged

Buying a pre-owned EV presents a new concern for buyers to beware of—the health of the vehicle’s battery. Some older EVs—notable the air-cooled Nissan LEAF—have poor records in this department. All batteries degrade over time, and there’s no simple way for a buyer to know how much of its original range a used EV retains.

How do you take clean AC mainstream? This global health organization has some ideas.

Grist

As we discussed in our last newsletter, all that growth also creates something of a vicious climate cycle, because of the energy-intensive nature of cooling, and because the refrigerants commonly used in ACs are potent greenhouse gases. A man installs an AC unit on the side of a building in India’s capital, New Delhi, this summer.
