Bilan Carbone UNISDR WWF What is climate change? Global warming – doesn’t mean we’ll all just have warmer weather in future. As the planet heats, climate patterns change. It’ll mean more extreme and unpredictable weather across the world – many places will be hotter, some wetter, others drier. We know the planet has warmed by an average of nearly 1°C in the past century. That might not sound much, but on a global scale it’s a huge increase and it’s creating big problems for people and wildlife. What causes climate change? Burning fossil fuels Over the past 150 years, the world’s industrialised nations have changed the balance of the carbon cycle by burning huge amounts of fossil fuels (concentrated carbon such as coal, oil and gas) Breeding cattle and cutting down forests Industrialised nations have also breeding vast numbers of methane-producing livestock and cutting down the forests that naturally absorb carbon dioxide from the air. Trapped carbon dioxide Find out about the effects of climate change. Beyond 2°c:

Watch this video on your iPad or iPhone here From our friends at NASA comes this amazing 13-second animation that depicts how temperatures around the globe have warmed since 1950. You’ll note an acceleration of the temperature trend in the late 1970s as greenhouse gas emissions from energy production increased worldwide and clean air laws reduced emissions of pollutants that had a cooling effect on the climate, and thus were masking some of the global warming signal. The data come from NASA's Goddard Institute for Space Studies in New York (GISS), which monitors global surface temperatures.

Al's Journal The Earth Institute - Columbia University Impacts of global warming - WWF-Australia Our climate is determined by patterns of temperature, wind, atmospheric pressure, humidity and rain over a long period of time. There are different climates around the world, such as tropical, dry and moderate. As a large country, Australia has a variety of climates. The climate of an area determines its seasons and when they come and go. As humans, every aspect of our life is reliant on the natural environment. A healthy and stable climate is our most precious natural resource. What changes to the climate are humans causing through global warming? Global warming, caused by greenhouse gas pollution, is causing immediate and direct changes to the planet. The Earth's temperature had already warmed by 1°C compared to pre-industrial levels. • Hotter days: 2015 was the hottest year on record, the previous record was broken in 2014, and 2016 is expected to set a new record for the third year in a row. • Oceans are warming and acidifying: How is global warming affecting life in Australia?

Climate Change | Many Answers Climate change is a change in worldwide climate patterns, like the weather. It is a very important topic in current events because the world is seeing a very large change in climate due to global warming. Useful words and phrases Here are some words and phrases you might come across when researching this topic. Climate: Climate refers to the normal weather patterns of a place, such as average temperature, rainfall, wind etc. Climate change: The change in the normal weather patterns, which can mean warming, cooling, or other changes. Global warming: The long term rising of the earths temperature. Greenhouse effect: The warming of the earths surface and the air above it, caused by gases in the air that trap energy from the sun. Greenhouse gas: Is a gas that contributes to the greenhouse effect, for example carbon dioxide and chlorofluorocarbons. The ozone layer: The shrinking ozone later is an important part of the larger topic of global warming. A changing climate NASA's Climate Kids BBC News
