It's pretty easy to find scientific papers that make the claim that solar variation is likely to make a small difference compared to human cause climate change.

> Any reduction in global mean near-surface temperature due to a future decline in solar activity is likely to be a small fraction of projected anthropogenic warming. - [Ineson, S.et al. Regional climate impacts of a possible future grand solar minimum - https://www.nature.com/articles/ncomms8535]

> We as a country can do a lot, but what about other developing countries?

It's a difficuly question, lead by example? Change anyway, because the more time we have to develop countermeasures the smaller the magnitude of the problem will peak at? I don't know, but waiting for all countries to fall into line isn't going to work.
