for those of you unaware, the "Earth Strike" movement (see also: their Reddit, Tumblr, and Twitter pages) is an international planned protest movement that will ultimately culminate in a general, international strike on september 27th, 2019. as of today it's only been in planning for like a week and change (almost exclusively online, as a point of note) so a lot of kinks are still being worked out and i'm not even sure there's a centralized organization to it as of now, but among other things, it internationally seeks the following demands:

An immediate start on global co-operation to reverse the damage done to the earths’ climate, through unambiguous and binding agreements, by both world leaders and corporate entities, following IPCC projections of halving carbon net emissions by 2030 and zero net emissions by 2050;
International, unambiguous and binding commitments to halt the destruction of rain forests and other wildlife habitats, and
International, unambiguous and binding agreements designed to hold corporations accountable for the greenhouse gases they produce.

i think most of us can agree that ultimately, their current demands are not 100% feasible or are actively impossible (at least not without radical, extremely sudden societal change) and that the ship has most likely sailed on keeping climate change from having some serious impacts. but do you think that this movement has any potential of any kind to enact change going forward? is it destined to be another Occupy, where some of its goals are taken up into politics but ultimately the movement itself collapses due to infighting and external factors? can it even be truly successful at all, given its lofty aim of an international general strike? or is it likely to just outright evaporate into functional or actual irrelevancy given enough time?

Let's assume that they have full control over congress, so politics isn't an issue. I think looking at what a good global climate policy would be useful, because it allows us to see where we stand. It could also serve as a platform for future candidates.

It seems to me that the new president should take a wide-ranging series of measures to curb emissions in all the major domains: electricity, transportation, agriculture, manufacturing, etc. [1]. You might argue that measures taken in isolation from other countries are not sufficient. While that's true, someone has to start. The US taking the lead on climate change would have a profound impact on all other countries. The US could use its very strong diplomatic weight to pressure other countries to adopt similar measures.

So what should these measures be? The major one would seem to be a carbon tax, applied to all major sources of emissions: energy production (coal plants, ...), agriculture (cattle and meat imports), jet fuel (current taxes are very low), etc. Another one could be a tax on imports depending on how much the exporting country does against global warming. Maybe a new kind of free trade alliance among "climate-virtuous" countries could be created.

Any thoughts? Have any serious global policy proposals been made and studied in the past?

Impact can be in many different areas (carbon emissions, energy use, water, plastics, land use, advocacy etc etc). I just want to know something you're doing that helps the environment. It can be big or small, something you've done for a long time, just started or want to implement soon.

I'll start, about 18 months ago I bought a bike and started cycling again. Most of my shorter journeys are now by bike and I'm looking at cycling to work.

Environmental news is often really bleak, lets hear some positive efforts!
