Greenhouse gases and all that stuff that warm the planet have warmed it something like 2.4 degrees over the last 150 years. Airliners create all those lovely contrails that eventually turn into high altitude clouds. High altitude clouds reflect sunlight back into space more effectively than low altitude clouds and snow on the ground (really, snow does that). This has increased Earth's planetary albedo (the amount of light reflected off an object) so much that the ambient temperature of the Earth has been reduced 3.1 degrees. So taking the 2.4 degrees warming minus our 3.1 degrees from increased albedo and we've cooled the planet off .7 degrees.
