The HFC challenge: Can the Montreal Protocol continue its winning streak?
by Jane Palmer on 5 May 2021
Since the Montreal Protocol was signed in 1987, countries have phased out most of the ozone-damaging gases, but their replacements, the HFCs, are powerful greenhouse gases that contribute to climate change.
In 2016, national delegates agreed on the Kigali Amendment to the Montreal Protocol, which calls for cutting the production and use of HFCs by 80–85% by the late 2040s. The amendment entered into force at the start of 2019, with the goal of avoiding additional warming by up to 0.4°C (0.72 °F) by the end of the century.

The next time you go for a hike, take an extra moment to appreciate the seemingly ordinary life all around you. A house fly, humble yarrow weed and other generalist plants and pollinators play a crucial role in maintaining biodiversity and may also serve as buffers against some impacts of climate change, finds new University of Colorado Boulder research.
The findings, published this month in
Ecology, provide valuable insights for prioritizing the conservation of species that contribute to the strength of ecological communities. A lot of times, conservation efforts are geared toward things that are rare. But oftentimes, species that are common are also in decline and could go extinct, and that could have really big repercussions for maintaining biodiversity, said Julian Resasco, lead author on the study and assistant professor of ecology.

Hi, my name is Scott C. Waring and I wrote a few books and am currently a ESL School Owner in Taiwan. I have had my own UFO sighting up close and personal, but that s how it works right? A non believer becomes a believer when they experience their first sighting. You witnessed it, your perceptual field changes, so now you need to share it.
