<p>Within days of record high temperatures in East Antarctica, an ice shelf the size of Rome collapsed completely in East Antarctica.</p>

<p>Scientists&nbsp;report&nbsp;that the Conger ice shelf collapsed around 15 March, it had a surface area of approximately 1,200 square kilometres.</p>

<p>Despite the small size of the Conger ice shelf, Dr Catherine Colello Walker, Earth and planetary scientist said, “it is one of the most significant collapse events anywhere in Antarctica since the early 2000s when the Larsen B ice shelf disintegrated”.</p>

<p>Walker said it won't have significant effects, but it could be a sign of things to come.</p>

<p>Concordia station in East Antarctica, recorded a record temperature of -11.8C on 18 March, about 40C higher than seasonal norms. Temperature records were set as a result of an atmospheric river that trapped heat over the continent.</p>

<p>Walker noted that the Conger ice shelf had been shrinking since the mid-2000s, but it was only slowly diminishing until the start of 2020.</p>

<p>Yet by 4 March, the ice shelf appeared to have lost more than half its surface area as compared with January measurements of approximately 1,200 square kilometres.</p>
