Transcript for How Could Your Actions Affect Glacial Meltdown?
So, of course, Amy's adventure in Iceland took our breath away. Got such a great response from so many of you but a lot of questions did happen so joining us to help answer some of them climate expert Bern net woods placky, the chief meteorologist at climate central and a fellow Penn state graduate so we know she knows her stuff. We are. I was asking before, I was joking in "Pop news" about the fat cares and said does that worry you, you said honestly yes because the ecosystem is out of balance. It is. I mean that's really the core of climate change and we're going to get into a lot of that right now. We have a lot of questions, I know my kids had questioned and we've got questions from some of our viewers. And I want to start with this one. Sheryl on Twitter says with all the ice water going into the ocean how is it that ocean temperatures are rising? Well, that's an interesting question. But take a glass of water, for example, when you first put the ice in, it does get colder but over time that ice melts and the water warms, that's the same thing that's happening. Our whole Earth system is connected and the more greenhouse gases like carbon dioxide from burring of oil, gas and coal we're warming our system more and more so eventually over time the ice will melt because temperatures are going up and then the whole Earth all of the water continues to warm. Really scary. Rodney on Twitter says are glaciers growing in other parts of the world or are they all melting. They're melting and retreating but I want to get into the difference between land ice and sea ice here because I think maybe where this is coming from is that we hear about growing sea ice in the antarctic. Now, in the arctic it's melting like crazy. But land ice is different than sea ice, glaciers are land ice. So we're putting more ice and more water into the ocean when they melt. Again, that glass of water, when you put more in -- People live on the coastline should be panicking and moving inland. They should be staying it seriously. We never want panic but we need to take it seriously. There are ways we can solve it. Can you give us a couple of quick tips we can take away and start doing today? We need small things but we need big things. So the big transition away from carbon dioxide and fossil fuel is important because it has big impacts but also on a local scale learn how the little things play a part. How we can recycle more, what else we can do. Stop using as much plastic bottles and our bags and one thing that always gets me too I'm the first one for a good cup of coffee but bring your own mug. I want to get a couple of video questions. Here's little Leila. Take a look. Really want the polar bears to have food to eat so that they won't be hurting. I don't know how to fix it and I really want to. Leila -- Cry. Leila, you're not the only one. A lot of people are working on this issue. It is a serious one, serious impacts but there are ways we can fix it if we all work together for this. Okay. And then one more question from a concerned kid about conserving energy. Take a look. Hi, I'm Charles from Texas. If I always turn out the light what other way can I conserve energy? That's great. That's a great thing. The more you can conserve energy and reduce your impact on the planet, the more you're going to help everything and that's all resources, energy, you know, turn down the temperature a little bit from your heat and vice versa. When it's your air-conditioning, turn down or excuse me, turn up the temperature from your air-conditioning. Also, get on your feet. Walk somewhere. Take a bike somewhere. You don't always have to get in a car. Home gardening is a great solution to a lot of issues and it's healthier and you save money. So little things really do matter. Thank you to all of our kids and everybody asking questions and thank you, my fellow Penn stater.
