We have experienced the highest global temperatures in 11,000 years. The temperatures on Earth are getting higher than they’ve been in about 11 thousand years. A new study mapped out worldwide climate trends up to the last ice age around 11 thousand 3 hundred years ago. Climate records kept by instruments only go back to the late nineteenth century. So climate scientists from Oregon State University and Harvard University used data from various sources like tree rings, and ice cores from Greenland and Antarctica to record the history of temperatures on our planet. The Intergovernmental Panel on Climate Change says by the end of this century, temperatures on our planet will reach the highest they’ve been since the end of the most recent ice age. Temperatures on Earth have risen dramatically in the past 150 years with the increase of industrial greenhouse gas emissions. Changes in the tilt of the Earth also affect the global climate, but Shaun Marcott, one of the authors of the study said: "If you were to predict based on where we are relative to the position of the sun, and how we are tilted, you would predict that we would be still cooling, but we're not.” Every decade since the 1960s has been progressively warmer than the previous one.
