Hi – I’m, Dr Sarah Gallagher, raccoon in an astronaut suit. Yes, now we have your attention. We’re, going to talk about climate change. What do raccoons have to do with climate change? Well, did you know that if the levels of carbon dioxide go to the levels they’re predicted by 2050 raccoons are going to start moving further north into colder areas, and while raccoons are cute, they cause a lot of damage when they move into Ecosystems where they don’t belong.
So we’re going to talk about five things. Satellites can do to help with climate change number one. They help. Scientists see the big picture in a country as large as canada. We need satellites to keep track of the whole country.
We can look at the land, the water and the atmosphere and see how they interact and change over time, including the impacts from climate change. Number two satellites help scientists, study clouds and their impact on climate and weather.
You may not know it, but those cute fluffy clouds could actually have a bigger impact on climate change than greenhouse gases. Number three measure: carbon monoxide concentrations, satellites, help us measure the amount of carbon monoxide so that we can check if those anti-pollution measures are really working.
Number four monitor signs of coastal erosion. Canada has the longest coastline in the world. Coastal erosion puts roads the homes of people who live nearby and marine ecosystems at risk, number five monitoring, the ozone layer and the substances that can damage it.
A thinning ozone layer leads to increased uv radiation, which increases our risk of sunburns and skin cancer.
