Not climate change… but…
“Thin cloud cover.”
RedOrbit reports:
Scientists have been trying to determine what led to the 50-year-record ice melt in Greenland. In April a team of scientists wrote in the journal Nature that they determined that the ice melt could be due to thin cloud cover.
The team was “…using computer model simulations and satellite data. They also analyzed weather station data.”
If you MUST use simulations, that is the correct way to use them – in tandem with real world data.
