That 2 Trillion figure sounds more like Global military spending:

The Federal Budget in Fiscal Year 2022: An Infographic

The difference between outlays and revenues is the deficit (or, if revenues
exceed outlays the surplus.)
Just like our Republican friends, I would like to cut the deficit. We can either raise revenues or cut outlays or both. Every presidential candidate promises to balance the budget, and to eliminate waste. If there's a lot of "slop" in the budget, that should be easy. (Right?) Unfortunately, Joe Biden had a hand in cutting a lot of waste when he was Vice President.
As I said, you and I may have departments we would like to see cut. I'm guessing that you would not want to cut social programs (Medicare, Medicaid, Social Security that sort of thing.) They make up most of the
mandatory spending. That rules out most of the budget.
You and I might think that the Defense Budget seems like a likely source. About 751 Billion in "
Discretionary Spending." Lets just pause on that one. If we eliminate
all military spending (apart from veteran's benefits which are under mandatory spending) wed only cut the deficit in half!
Interest on the national debt (at roughly 500 Billion) equals about two thirds of the military budget!
Im not saying we dont spend a lot on Defense Im saying servicing our national debt is eating us alive, and every year we pile more deficit spending onto the debt, and, yes, I blame most of the debt on George W. Bush and Donald J. Trump, but it doesnt matter much now who gets the blame. Its our debt now
How much money will we need to cover the Climate Emergency? OMB
tried to estimate that:

Identifiable Costs
The Office of Management and Budget (OMB) assessments found that the Federal Government could spend between an additional $25 billion to $128 billion annually due to just six climate-related financial risks included in this reportdisaster relief, flood insurance, crop insurance, healthcare expenditures, wildland fire suppression spending, and flood risk at Federal facilities and considering only a limited scope of total potential damages to those programs.
OK, that's essentially an admission that even the $128 billion high end estimate is low.
Non-Defense discretionary spending was goosed by COVID-19. For a few years prior, it was running "neck and neck" with the Defense budget. Perhaps the amount of emergency spending we have spent fighting COVID-19 would cover it, but thats all deficit spending, and (unlike COVID) were not expecting it to be temporary. When do you anticipate
this emergency spending will end? (How long will it take us to fix the climate?) I think we can only expect the need to
increase each year.
I dont think we can find it by trimming fat from line items.
