Experts compare ice cores taken in 1995 and 2011, finding alarming spike in temperatures; lead author of study says findings are 'clear signature of global warming'
By Rachel Ramirez, CNN As humans fiddle with the planet’s thermostat, scientists are piecing together Greenland’s history by drilling ice cores to analyze how the climate crisis has impacted the island country over the years.
Scientists say warming in Greenland in the past may have been masked by local weather variability. But not any more. Climate change is blowing that away.
New ice core data shows Greenland is the warmest it's been in more than 1,000 years. Until Wednesday's study, scientists didn't have recent ice core data. The last ice core was from 1995.
