The urgency of taking action on extreme events in Antarctica

Steven

Hey Stephany, did you see that article about the extreme events in Antarctica? Scientists are warning that they will get worse if we don't take drastic action to limit global heating.

Stephany

Yes, I did. It's really concerning. The review highlighted record low sea ice levels, the collapse of ice shelves, and even surface temperatures that were 38.5C above average in East Antarctica last year. The world's largest heatwave ever recorded!

Steven

Exactly. And it's not just the sea ice that's a problem. The land ice in Antarctica has been declining since the 1990s, contributing to rising sea levels. Between 1992 and 2020, the Antarctic and Greenland ice sheets have caused a 2.1cm rise in global mean sea level.

Stephany

That's a significant contribution. And the rate of ice sheet loss from Antarctica matches the worst-case predictions for ice loss under high greenhouse gas emissions scenarios. It's alarming that we're already tracking along the most extreme prediction of what might happen.

Steven

But Stephany, not all scientists agree. Some argue that the policy response so far has been inadequate to address the climate crisis. They believe we need to do more to reduce greenhouse gas emissions and prepare for the consequences, like sea level rise and extreme weather events.

Stephany

I understand that perspective, but we can't ignore the evidence of the extreme events happening in Antarctica. The study warns that future Antarctic extreme events will be even more pronounced than what we've seen so far. We can't afford to wait any longer to take action.

Steven

I agree that action is necessary, but I think we need to consider the economic implications as well. It's not an easy problem to solve, and we have to find a balance between protecting the environment and ensuring the stability of our economies.

Stephany

I understand your concerns, but we can't prioritize short-term economic gains over the long-term health of our planet. We need to invest in research, improve our understanding of ice and ocean processes, and coordinate efforts globally to address the challenges in Antarctica.

Steven

You make a valid point. It's a complex issue, and we need to find a way to address it effectively. But for now, let's stay informed and spread awareness about the urgency of taking action.

Stephany

Absolutely. We all have a role to play in addressing the climate crisis. The more people are aware of the situation, the more pressure we can put on governments and industries to make the necessary changes.

Stephany

I have to go. I must finish an assignment for work. Let's continue this conversation later.

Steven

Of course, take care and talk to you soon.
