A significant number of New Zealanders overestimate sea-level rise — and that could stop them from taking action

Survey respondents who overestimated the amount and speed of sea-level rise were more likely to express greater concern. But concern is not always helpful in prompting action.

Bila pemanasan global melebihi 2°C, lelehan es Antarktika bisa menaikkan muka laut hingga 20 meter

Penelitian terbaru menunjukkan pemanasan lebih dari 2°C menjadi titik penting bagi lapisan es di Antarktika, yaitu pencairan es secara besar-besar dan perubahan garis pantai di masa mendatang.

If warming exceeds 2°C, Antarctica’s melting ice sheets could raise seas 20 metres in coming centuries

New research shows that warming by more than 2°C could be a tipping point for Antarctica’s ice sheets, resulting in widespread meltdown and changes to the world’s shorelines for centuries to come.
