TFAs are here forever. Short term risks seem minimal. The long-term picture is murkier and more concerning. TFA’s extreme persistence (no natural degradation in terminal sinks like oceans or deep aquifers) means accumulation is effectively irreversible. Sticking with TFA-forming refrigerants locks in decades of accumulation for short-term gains in global warming potential (GWP).

ARCSA’s Role in Meeting California’s Water Needs
A well-designed, installed and maintained rainwater harvesting system can provide significant amounts of high-quality water for potable and non-potable, residential and commercial uses.
Warm temperatures and rainfall reduce snowpack across the West this week
The current snow water equivalent percent of median map shows a reduction in percent of median at many stations in the West from a week ago. Many stations in the northern part of the West are near or below median. The highest percent of median continues to be across southeast Oregon, northern California, Nevada, southern Utah, and Colorado

Petition to Support Rainwater Harvesting
…to stimulate the emerging rainwater-harvesting industry through legislation or executive order, creating new jobs in design, installation, education, R&D, sales, plumbing, landscaping, roofing, monitoring and maintenance, which could propel the U.S. to international leadership, with compounding fiscal benefits.
California’s Plan to Harvest Rain & Stormwater
A well-designed, installed and maintained rainwater harvesting system can provide significant amounts of high-quality water. Given an average 12 inches of annual Southern California precipitation, a 1,500-square-foot residential roof could collect over 10,000 gallons annually; and for a 100,000 ft2 commercial building, the quantity is over 700,000 gallons.
