It took them ages to acknowledge there was actually a problem!

Scientists hope a drill that can plunge 3 kilometres down into an Antarctic ice cap and withstand temperatures of -55 degrees Celsius will help solve one of the last great puzzles in climate science.
Important mystery there - possibly that CO2 levels finally fell so low that ice ages suddenly became the default condition on earth.
... "We want to get that ice, analyse those time capsules and understand what [carbon dioxide] did through that period around a million years ago when the climate was changing."
One million years ago, Homo erectus was walking the Earth and Australia was home to megafauna such as the rhinoceros-sized 'wombat' Diprotodon.
At the same time, the Earth's climate made a shift from a 40,000-year ice age and interglacial cycle, to a 100,000-year cycle.
