China invests a significant chunk more into renewable energies than the US. More than double actually.

In fact, a higher percentage of their total energy is met by renewables than for the US. They have 3x the capacity of the US while their per person energy usage and emissions are still significantly lower than US.

Let's not pretend China does nothing.

We know how to address China, and other nations. By international agreements and trade.

We have already done it multiple times. Does really no one remember the refrigerator gases, the CFCs?

The same economic doomsday arguments were made at the time, without them food production would suffer globally, and it won't matter anyway since it is a global problem and what about all the countries that will keep using them?

The onus on making a similar argument with greenhouse gases today would be on the ones saying it's impossible this time. The greenhouse situation may be so much more complex but the economic arguments are the same. We know how to solve them, by trade agreements and international tariffs.

I'm not really sure China needed to be addressed. Simply putting significant money into green tech would have had a variety of effects - build out the sector earlier and faster; threaten control of the sector without competitive investment in other countries; demonstrate that the largest economy in the world is willing to put its money where its mouth is.

Realistically, through something like strong(er) accords and negotiation. But the first step is understanding the problem, recognizing it, and declaring an intent to address it with international cooperation. Saying "but my neighbor won't help" doesn't seem effective to get anything done. The mixed signals regarding thew science also don't help.

One of the principles of negotiation is showing goodwill, so let's all just start by doing our part, and then the international community can have a strong negotiating position with defectors. Being a defector ourselves doesn't help! (I prefer to suffer while striving for a good, than suffer slightly less knowing I'm part of the problem)

there are several ways to deal with countries that aren’t good citizens. I’d rather skip the conversation for the 100th time. Maybe you could come up with some common sense solutions? The funny thing about dealing with climate change, deniers, etc. is that once all the questions have been answered, they start all over again at the beginning.

The sort answer is: It’s really not an excuse for us not doing anything.

One strong option is tying large tariffs to failure to hit emission reduction targets or failure to implement other globally determined necessary policies.

Like with everything, the problem isn't a lack of practical solutions, it is a lack of willpower to pay the short term polical / economic costs needed to avoid massive long term harm.

There are probably more than a billion up and coming people in China, India, and other developing countries that would love to take advantage of lower flight and hotel prices in tropical destinations.
