I need help from the DU community to address my most important letter to the President.

1. K/R and two points of advice: Less is more, be concise, and give one example of feedback loops.

.

It's the hardest thing to do in writing, to say the most with the fewest words.

But it's very important, you might lose the reader with how much time you spend on the importance of your letter.

I suggest one short sentence about how important this is to you, follow that with the subject in one sentence, irreversible feedback loops.

Then give an example, ie albedo and the icecaps or ocean warming and thawing of solid methane hydrates.

I think we can assume he knows some of the big picture details, so save your words for the key points and I think it will be a more powerful letter.

Good luck!
