Jakarta - Sejumlah ilmuwan menyatakan lapisan es di Greenland kembali mencair pada tahun 2019, memecahkan rekor sebelumnya yang mencapai 15%.

According to a study released on Thursday, Aug. 20, 2020, Greenland lost a record amount of ice during an extra warm 2019, with the melt massive enough to cover California in more than four feet (1.25 meters) of water.

A German icebreaker carrying scientists on a year-long international expedition in the high Arctic has reached the North Pole, after making an unplanned detour because of lighter-than-usual sea ice conditions. Expedition leader Markus Rex said Wednesday the RV Polarstern was able to reach the geographic North Pole because of large openings in sea ice that would normally make shipping in the region above Greenland too difficult.

Namun, para peneliti menilai bahwa emisi karbon yang terus bertambah mendorong Greenland ke tahap pencairan yang lebih ekstrem. Markus Rex/Alfred Wegener Institute via AP  

ILULISSAT, GREENLAND - JULY 30: An iceberg floats in Disko Bay behind houses during unseasonably warm weather on July 30, 2019 in Ilulissat, Greenland. The Sahara heat wave that recently sent temperatures to record levels in parts of Europe is arriving in Greenland. Climate change is having a profound effect in Greenland, where over the last several decades summers have become longer and the rate that glaciers and the Greenland ice cap are retreating has accelerated.

Menggunakan data dari satelit Grace dan Grace-FO, serta model iklim, para peneliti menyimpulkan bahwa selama setahun penuh Greenland kehilangan 532 gigaton es. Ini adalah peningkatan yang signifikan dibandingkan pada 2012. Sean Gallup/Getty Images

Para peneliti mengatakan mencairnya lapisan es Greenland itu setara kenaikan permukaan air laut setinggi 1,5 milimeter. Angka itu sekitar 40% dari kenaikan rata-rata muka laut dalam satu tahun. Sean Gallup/Getty Images

Menurut penghitungan oleh ilmuwan iklim asal Denmark, Martin Stendel, jumlah es yang mencair di Greenland tahun 2019 itu cukup untuk menutupi seluruh wilayah Inggris, dengan sekitar 2,5 meter es yang mencair. Sean Gallup/Getty Images

Tahun 2019 dan 2012 ditandai dengan peristiwa "pemblokiran", kata para peneliti. Artinya, gangguan pada aliran air menyebabkan sistem bertekanan tinggi di Greenland macet. Akibatnya, terjadi peningkatan pencairan. Sean Gallup/Getty Images

Walau tahun 2019 memecahkan rekor, penurunan skala pencairan es terjadi pada tahun 2018 dan 2017, lebih rendah daripada periode dua tahunan lainnya sejak 2003. Sean Gallup/Getty Images

Meskipun di tahun 2020 terlihat kondisi rata-rata di Greenland, dampak keseluruhan dari hilangnya es yang terlihat dalam beberapa tahun terakhir dapat memiliki implikasi besar bagi orang-orang yang tinggal di daerah dataran rendah di dunia. Sean Gallup/Getty Images

Laporan media baru-baru ini menyatakan bahwa Greenland mungkin telah melewati titik tidak bisa kembali, bahwa tingkat pemanasan global yang sudah dilakukan dunia karena emisi karbon, berarti bahwa semua Greenland akan mencair. Sean Gallup/Getty Images
