The reason for that is: as a layman I know that snow reflects sunlight. Surely, climate researchers would have figured out that this is one of the main factors that can change over time.
Ah well, I guess I was to optimistic. It's good to know that they found out now.
Their results are pretty worrying. Quoting again: "This heating of 0.71 W/m2 is approximately equivalent to the direct radiative effect of emitting one trillion tons of CO2into the atmosphere (see calculation in Appendix A). As of 2016, an estimated 2.4 trillion tons of CO2 have been emitted since the preindustrial period due to both fossil fuel combustion (1.54 trillion tons) and land use changes (0.82 trillion tons), with an additional 40 billion tons of CO2 per year emitted from these sources during 2007–2016 (Le Quéré et al., 2018). Thus, the additional warming due to the complete loss of Arctic sea ice would be equivalent to 25 years of global CO2 emissions at the current rate. This implies that if the Arctic sea ice were to disappear much more rapidly than in current climate model projections, it would drastically shorten the time available to adapt to climate changes and the time for achieving carbon neutrality."
I really wonder if this climate destruction is a form of warfare. It certainly favours countries in higher latitudes.
Trump actively made things worse and I am not sure if relativizing things in such an important area is a good thing.
Because the fire brigade that actively denies your country is on fire and pumps gasoline into it just to show it to you is objectively worse than the one that clumsily falls over their own protective gear while spraying your country with way too little water.
I’m not sure if you’re aware of this, but we as a planet are guilty of doing nothing. It’s not beholden on any single country to save the world.
Yes, trump pulling out of the Paris accords is quite frightening, but if the US public didn’t have an appetite for convenience over longevity then we might not have such an issue.
I know I’m guilty of being wasteful and not supporting renewable or carbon neutral alternatives (I even complained that my energy prices are going up much faster due to the push for renewables).
But that’s where it needs to start. Not blaming those at the top; trying to inspire those down here who could be swayed to have a little less convenience in their lives and to buy from companies that pledge to be carbon neutral.
E.g. people wouldn't get a choice to buy from non carbon neutral businesses if legislation was put in place to ramp up a carbon fee. And they would all benefit from this.
