No government planner knows how much you value combating global warming.
It doesn't matter how much I value combating global warming. There's a certain amount needed to combat global warming completely independent of my feelings.
This is why we can be 99.99% certain that the amount of resources currently allocated to combating global warming is inefficient.
No, we can be certain it's inefficient because it's less than the scientific consensus.
But what if we eliminated the government entirely? Would the amount of money that you spent on combating global warming accurately reflect your valuation? If so, then you would probably be the exception rather than the rule.
Of course not, but it wouldn't matter if it would. My valuation of it is irrelevant to the fact of need.
The premise of compulsory taxation is that people will voluntarily pay less than their valuation of public goods. This means that in an entirely voluntary society, we can be around 70% certain that the amount of resources allocated to combating global warming would be inefficient.
We can be certain of that, yes. But even if we followed everyone's preferences exactly and entirely via mind reading device, it may still be inefficient if it doesn't match the amount needed according to science.
So what if we simply allowed taxpayers to choose where their taxes go?
Then the government would either become stupid inefficient or collapse entirely.
Would the amount of money that you spent on combating global warming accurately reflect your valuation?
No. Of course not. What a silly question.
Why not?
Because, as a tax professional, it's most rational for me to entirely fund the IRS with every bit of tax money I pay, because that puts food on my table and money in my wallet. Meanwhile, I use the roads, environment, etc, that YOU pay for even though I don't pay for it.
You have to pay taxes anyways.
Yes, but that doesn't matter. My true valuation won't be reflected - I'm a rational actor. I will fund that which loops back the most money into my pocket, not what I truly value.
As a result, the amount of resources allocated to combating global warming would be far more efficient compared to the alternatives.
Not even by your gross definition of efficient where runaway greenhouse global warming extinguishing all life on earth is efficient.

In order to have scientific study you first need to have scientists. How many scientists should study global warming? Are you going to use scientists to answer this question? If so, how many scientists? Are you going to use scientists to answer this question? If so, how many?
As many as it takes to understand the problem and solution to a high degree of accuracy.
Right now a small group of elected non-scientists determines how many scientists should study global warming. You're certain that a few elected non-scientists will come up with a better answer than all the taxpayers combined. Do you have any scientific studies to prove this? Nope.
No, but it still makes more logical sense than your system.
