Partnering Countries Will Harness the Power and Expertise of the U.S. Government, Philanthropic Groups and Academia to Scale Up Clean Energy Deployment and Investment.

As nations convene for the United Nations Conference of the Parties, or COP26, in Glasgow, Scotland, their pledges to reduce greenhouse gas emissions will, if fulfilled, shape Earth’s climate over the next century and beyond. A new study in the journal Science finds the recent pledges could eliminate the chance of global temperature change rising to 4°C, bringing the goal of limiting warming to 2°C closer to fruition.

When added to any hydronic system at a low concentration, a non-ionic surfactant has been shown to reduce surface tension inside pipes and coils by 60%, enhancing heat transfer.

The scientists developed nanoscale copper wires with specially shaped surfaces to catalyze a chemical reaction that reduces greenhouse gas emissions while generating ethylene — a valuable chemical simultaneously.

When replacing R-410A, engineers should consider commercially available, single-component, or azeotrope refrigerants that meet AHRI Standard 700 with zero ODP and a maximum 750 GWP.

For Chicago, the best-case scenario is that electricity use increases by 12% and water use increases by 4% if global warming crosses a 1.5°C threshold. But if a 2.0°C threshold is reached, then the worst-case scenario is a 20% increase in electricity use and a 6% increase in water use.
