CMV: Globalism is necessary to combat climate change

Tomorrow I have to vote. As someone living below sea level and alarmed with studies predicting that there will be no land suitible for wheat in Africa at 2080 (Fisher), good environmental policies are a major factor influencing my vote. There are only two parties that have leading environmental policy in their party program. An important difference between the two is their attitude against european integration and international trade. One sees european and international cooperation as essential for preserving our current biosphere, under conditions such as transparancy and testing the policies for environmental and social impact. The other is against increased european cooperation and supports pro-exit policies, as well has a harsher stance towards international trade cooperation.

To me it made more sense that increased integration with other countries would be most effective for restoring our balance with the biosphere. Climate change comes with high regional variability and will impact different countries in different ways. While most will be negatively affected, some at higher lattitudes, like Russia, may see an increase in arable land for instance. Only when their economy is integrated with the rest of the world and therefore their standard of living is dependent on the rest of the world also being well off, will they care enough to use their enormous potential in combating climate change (Kotilainen for more on this). So only when caring for others is the same as caring for yourself will enviromental policies be implemented fast enough to stop the most disastrous effects of climate change. Increased cooperation economically could also help facilitate the cooperation necessary for fair world wide policies that are needed to combat climate change. 

Disclaimer: I am not certain about voting for either of these parties and I care about other parts of their program too, this question is more about a debate between environmentalists that has not yet been resolved (or mentioned here before), even though it seems quite important. I also assume a few things, such as countries acting quite egoistic. I am also not informed about for instance the impact of globalism currently compared to a world where countries would be more closed off. It seems like that topic leaves a bit too much space for speculation and is maybe better for a seperate discussion (will Trump bringing back factories to the states, if it works, mean more mechanized and perhaps therefore more energy intensive industry? Or will this effect be negated by overall economic downturn as a consequence, or is it the other way?).

I assume cooperation is a non zero sum game, while climate change is?

Climate change would be over tomorrow if someone figured out how to make solving it profitable.

A single world government or globalism in general is always doomed to fail because it requires people to either willingly cede authority or have it taken from them (and awarded to people that will only use it to feather their own nests anyway. You're giving the worst class of people - politicians - even more power, after they've failed to address the problem with the immense resources and influence they have presently).

If there is a solution for climate change it won't be coming from politicians with a track record of failure, it will come from technological advancements (which will be implemented by the private sector). Look at the advancements in renewables and battery tech for example - businesses may or may not give a shit about the environment, but they do about profits.
