TR's record stands well today (yes, some blemishes---he basically "grabbed" the Panama Canal land, he was not fair with some African American vets...) but yet TR, the (gasp!) rich Republican, who became a rancher for a short time after his first wife's death, did some decent things...  
  He read the book "The Jungle" (remember that sorta gross book they might have made you read about a ghastly meat packing plant---sounded like something out of a horror movie...)
  Rats, maybe even human body parts...in the meat. Immigrant workers treated as slaves. He ignored the author's socialistic solutions, but did get food standards in after finding the book was substantially true. 
  He made the striking miners and mine owners meet and work things out. Unions and strikes are no big deal now, but then, this gave some needed status to the workers.
  He also (no doubt due to his brief Western experience) added LOTS of parks, etc. to the national protected lands. He then, commented on the need to preserve and not merely use up the nation's resources. (People then thought our natural supplies were unending.)
  Based on his policy of (usually) researching claims, and usually investigating issues himself  (when a legislator, he actually entered horrible NCY tenement slums before proposing slum improvement legislation, he actually walked the streets (when police commissioner) to make sure the average cops were doing their jogs...one could assume TR would take global warming claims (and all the permutations) seriously. He would do research on it himself. He would also bring a love of the human species to the "global warming" table. 
  He broke up some huge strangling trusts who controlled sugar, railroads, and other critical national resources.  (They 'd make Microsoft look like a dime store.)
  He, early on, recognized the aggressive potential of the Kaiser's Germany and of that era's Japan and sent around this big fleet of ships just to visually intimidate them. (This might be his most unpopular feat to some here. But the 20th Century's later wars prove he was essentially right.)
  His distant cousin Franklin, tho Democrat, had a big boost his first election by coming in with the Roosevelt name. And niece Eleanor in her work reflects some of the general Roosevelt family values---most of which are honored by history. 

One core value of this rich, priveleged family:

"The strong should care for the weak."  Not an exact quote but a summary of their aims.  These rich, privileged persons were serving those who have less.  (We may take issue with some of their decisions, but I hope not with their core value!)
