Global Warning! What is global warming? Why should we care? What can we do? Why is the planet heating up? Scientists predict that the Earth will warm by 1.4 - 5.8C in the next 95 years! Does it matter? The Intergovernmental Panel on Climate Change (IPCC), a consortium of several thousand independent scientists. How much colder was the last ice age? Guess: 5, 10, 100, 1000 degrees colder than today? The last Ice Age was only 5C colder than today! EffaithTy Gwydr / The Greenhouse Effect The gas from pollution traps the heat from the sun and causes our planet to overheat. Recent records show that our climate is getting warmer. Sea ice is melting. Our climate is already changing! In America ice is disappearing. Our sea levels are rising. Our climate is already changing! Rising tides. Some scientists predict that a warmer climate will trigger more violent storms, which will cause increased rates of coastal erosion. Cape Hatteras in North Carolina in the USA. Our climate is already changing! Low-lying Bangladesh is prone to coastal flooding caused by storm surges, which have killed thousands of people in recent years. Experts say if the sea level goes up by 1 metre, Bangladesh will lose 17.5% of its land. Our climate is already changing! UK October 2004 Experts predict that fierce storms and floods are likely to become more frequent in the future. If homes and factories continue to be built on floodplains, the cost of severe flooding will soar. Most scientists agree that pollution levels are contributing to global warming. Look at the graphs. What do you think? The Intergovernmental Panel on Climate Change (IPCC), a consortium of several thousand independent scientists. In 25 years… Worst case: if high pollution emissions Best case: if low pollution emissions How old will you or your children be? The way we live will determine the temperature. In 91 years… If we do If we reduce pollution nothing The choice is ours Newidiadau i gyfartaledd tymheredd blynyddol Predicted changes in annual average temperature Scientists predict that by 2080 Wales will experience: An average increase in temperature of by 2% Scientists predict that by 2080 Wales will experience: More rain in winter and less rain in the summer Scientists predict that by 2080 Wales will experience: A rise in sea level that could range from 18-79 cm Scientists predict that by 2080 Wales will experience: More extreme weather conditions and very severe gales 10% more drought years Why is the planet heating up? Global warming is the most serious threat facing our planet! Our challenge is to reduce CO2 But what can I do? Be energy – efficient! If every household installed two energy efficient light bulbs, enough energy would be saved in a year to supply all street lighting in the UK. Always remember to switch the bathroom light off after you go to the toilet. Only fill the kettle with the amount of water you need. Don't leave your computer on after you're finished using it. If you feel cold try putting on a jumper before you turn up the heating.
