If we live in a world with limited budgets we face tradeoffs in choosing to spend our limited resources on one thing over another.
If you had 100 dollars to spend (representing our pooled OECD disposable income) on either climate change, war, or poverty and each required 40 dollars to have any effect, which would you choose to spend money on?
Well, consider this:
1. Climate change poses an existential threat to the human race ... in 50 years.
2. War poses an existential threat to several million people today.
3. Poverty poses an existential threat to 1/4 of the human race today.
Changed your mind yet?
Bonus for choosing to fight poverty or war: you'll probably end up fighting against global warming too. Neither war nor poverty is good for the environment. I don't mean to say that poor people are inherently ignorant of environmentalism, and I recognize the biggest co2 producers are largely OECD, but it is clear which countries are growing economically, and degrading environmentally, the fastest today.
Of course the choices are not strictly discrete, but poverty and war are some of the worst offenders when it comes to climate change. If you are a humanitarian and are focused on fighting climate change, think about the millions of people trying to lift themselves out of poverty who have little regard for the environment. Undoubtedly, it is extremely difficult to lift oneself out of poverty without destroying a bit of the environment (have we ever seen a nation succeed?) so herein lies the challange:
The progress of nations; a selection from gapminder.org . Notice the slopes.
How can we develop without destroying the various resource cycles that allow us to continue to satiate our appetite for 'wealth' (which we cant seem to get over). How can we maintain our resources to ensure the well being of future generations while raising the living standards of the bottom two billion?
The climate change is invariably a problem of war, poverty and development, but war, poverty and development are more pressing and not (necessarily) a problem of climate change.
