The following post contains an interesting video link showing how the ice cores were examined to reveal the past record of temperature. At the very least this shows that the past 10000 years have been warmer than the present - something that climate alarmists have tried to deny. Of course this does not mean that increased CO2 levels do not cause warming, but the unknown factor is how much of the current warming is cased by CO2 and how much is due to natural causes?
A single location on earth's temperature records does not disprove climate change. That is a common fallacy being bantied about on the internet.

A misleading graph purporting to show that past changes in Greenland’s temperatures dwarf modern climate change has been circling the internet since at least 2010.
Based on an early Greenland ice core record produced back in 1997, versions of the graph have, variously, mislabeled the x-axis, excluded the modern observational temperature record and conflated a single location in Greenland with the whole world
We are warming. Make no mistake about it. Green land is going through massive amounts of ice sheet loss. As we continue to warm, the melt from the ice sheets will grow even larger than it is today. Renewable energy and electrification are the way out of this.

This modern temperature reconstruction, combined with observational records over the past century, shows that current temperatures in Greenland are warmer than any period in the past 2,000 years. That said, they are likely still cooler than during the early part of the current geological epoch – the Holocene – which started around 11,000 years ago.
However, warming is expected to continue in the future as human actions continue to emit greenhouse gases, primarily from the combustion of fossil fuels.
Climate models project that if emissions continue, by 2050, Greenland temperatures will exceed anything seen since the last interglacial period, around 125,000 years ago.
