Great link. Just made a few old fuckers at work sit through it. They are begrudgingly coming around to the idea that we’ve fucked the planet.
Australia always has been. We like to run the image of friendly and laid back and egalitarian etc, but it’s always been pretty redneck, racist and conservative. Education levels are better than the US, but have suffered the same deliberate defunding under conservative governments like the US.Straya. Pack of arseholes.
HFC134A has a lifespan of around 15 years. We can control HFC134A emissions quite easily.
- CO2, by definition, has a GWP of 1 regardless of the time period used, because it is the gas being used as the reference. CO2 remains in the climate system for a very long time: CO2 emissions cause increases in atmospheric concentrations of CO2 that will last thousands of years.
- Methane (CH4) is estimated to have a GWP of 28–36 over 100 years (Learn why EPA's U.S. Inventory of Greenhouse Gas Emissions and Sinks uses a different value.). CH4 emitted today lasts about a decade on average, which is much less time than CO2. But CH4 also absorbs much more energy than CO2. The net effect of the shorter lifetime and higher energy absorption is reflected in the GWP. The CH4 GWP also accounts for some indirect effects, such as the fact that CH4 is a precursor to ozone, and ozone is itself a GHG.
- Nitrous Oxide (N2O) has a GWP 265–298 times that of CO2 for a 100-year timescale. N2O emitted today remains in the atmosphere for more than 100 years, on average.
- Chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6) are sometimes called high-GWP gases because, for a given amount of mass, they trap substantially more heat than CO2. (The GWPs for these gases can be in the thousands or tens of thousands.)
Not sure I agree; the point you raise is true but reinforces rather than contradicts the article... We can control HFC emissions easily through regulation - there is a freely available, affordable alternative, and other jurisdictions have done so for a long time.HFC134A has a lifespan of around 15 years.

This story is another example of ".....look over there......>>>>>>>>"
Yeah but now we are talking about HFC emissions & not CO2 emissions.Not sure I agree; the point you raise is true but reinforces rather than contradicts the article...

The problem is, despite it being a total no-brainer, we still won’t, because what? Imposing market regulations has become so anathema that even when it’s just bringing our requirements inline with other (much larger) markets it’s somehow a step too far.
Addressing these things isn’t a distraction - every little bit counts. And when we’ve proven time and time again that we’re too weak to take big steps, The momentum building potential of the baby steps becomes more important.
