The Loch Ness Monster was killed by global warming.....

Now, it all makes sense...

LEGENDARY Nessie hunter Robert Rines is giving up his search for the monster after 37 years.

The 85-year-old American will make one last trip in a bid to find the elusive beast.

After almost four decades of fruitless expeditions, he admitted: "Unfortunately, I'm running out of age."

World War II veteran Robert has devoted almost half his life to scouring Loch Ness.

He started in 1971. The following year, he watched a 25ft-long hump with the texture of elephant skin gliding through the water.

His original trip was to help another monster hunter with sonar equipment and quickly identified large moving targets.

He was smitten and returned the next year, which is when, he says: "I had the misfortune of seeing one of these things with my own eyes."

Since then, he has been obsessed with tracking down the creature with a staggering array of hi-tech equipment. It was this gear that took the famous "flipper" picture that year which created a stir around the world.

Despite having hundreds of sonar contacts over the years, the trail has since gone cold and Rines believes that Nessie may be dead, a victim of global warming.
