Okay, first of all, there were only three American Aircraft Carriers in the Pacific, the USS Enterprise, Lexington and Saratoga on 7 December. The Enterprise was delivering fighter planes to Wake Island and on her way home. The Lexington was on her way to deliver scout bombers to Midway Island and the Saratoga was on the West Coast undergoing routine maintainence. The old carrier Langley had been relegated to the status of carrying aircraft for delivery and half of its flight deck had been removed. IIRC, the converted merchant ship, aircraft carrier, the USS Long Island was on her way to the Pacific.

The USS Yorktown and Ranger were with the Atlantic Fleet and the USS Hornet and Wasp were in various stages of completion/working up.

There were already plans in motion for the US Navy to quickly convert civilian ocean liners into ad hoc aircraft carriers, much like the Japanese did, until replacement, purpose built, aircraft carriers could take over for them.

I can't see the US abandoning Hawaii, simply because of the high degree of existing, military infrastructure and manpower already there, not to mention, the extreme difficulty that it would take for the Japanese to successfully invade the islands. With over two US Army Divisions, Marine Defense Battalions, not to mention thousands of Navy Bluejackets, those islands would have been a very tough nut for anyone to crack.
