LONDON (AP) — Britain’s polar research ship has crossed paths with the largest iceberg in the world — a “lucky” encounter that enabled scientists to collect seawater samples around the colossal berg as it drifts out of Antarctic waters, the British Antarctic Survey said Monday.

The RRS Sir David Attenborough, which is on its way to Antarctica for its first scientific mission, passed the mega iceberg known as the A23a on Friday near the tip of the Antarctic Peninsula.

Study finds ‘direct evidence’ of polar amplification on continent as scientists warn of implications of ice loss

Antarctica is likely warming at almost twice the rate of the rest of the world and faster than climate change models are predicting, with potentially far-reaching implications for global sea level rise, according to a scientific study.

Scientists analysed 78 Antarctic ice cores to recreate temperatures going back 1,000 years and found the warming across the continent was outside what could be expected from natural swings.

In West Antarctica, a region considered particularly vulnerable to warming with an ice sheet that could push up global sea levels by several metres if it collapsed, the study found warming at twice the rate suggested by climate models.
