Saved by BBC iPlayer Climate is the average weather conditions in a place over a long period of time (30 years or more). The third part, due in May, will focus on ways of curbing the rise in … Climate change is lasting change in long term weather patterns over a significant period of time. The natural causes of climate change 1. Natural factors increasing global warming, - the Earth has natural warming and cooling periods caused by. Big volcanic eruptions can change the Earth’s climate. BBC Bitesize Daily has got the amazing Cel Spellman presenting this week! Causes of climate change - GCSE Geography - BBC Bitesize. Causes and Consequences of Climate Change Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down rainforests and farming livestock . Here he is with a quick Bitesize lesson on climate change. Yes and no. Cutting down forests (deforestation). 4. Trees help to regulate the climate by absorbing CO2 from the atmosphere. To learn about climate change, you first must know what climate is. Human causes. What is climate change? IN THE NEWS Mayor quashes £25 C-charge hike. Burning fossil fuels Over the past 150 years, industrialised countries have been burning large amounts of fossil fuels such as oil and gas.The gases released into the atmosphere during this process act like an invisible ‘blanket’, trapping heat from the sun and warming the Earth. 3. The energy changes spread out around the globe upsetting climate processes. Cycles also play key roles in Earth’s short-term weather and long-term climate. - trees absorb carbon dioxide during photosynthesis. Evidence has shown that the Earth’s temperature is rising, and that an increase in greenhouse gases in the atmosphere is responsible. But some commentators are unconvinced that rising greenhouse gas emissions are the cause of … Climate change has positive and negative impacts and physical and human causes. BBC Weather explains. Small eruptions have no effect – the eruption needs to be very large and explosive. The Intergovernmental Panel on Climate Change (IPCC) said temperatures were probably going to increase by 1.8-4C (3.2-7.2F) by the end of the century. When humans burn fossil fuels, the natural concentration of CO. changes. or variations in the tilt and/or orbit of the Earth around the Sun (Wobble, roll and stretch theory). What is climate change? Another group of greenhouse gases includes the chlorofluorocarbons (CFCs). Greenhouse gas emission is a major human causes of climate change, and their sources include transportation, electricity production, burning fossil fuel in industries, commercial and residential application, agriculture, and land use. Burning fossil fuels, eg coal, gas and oil - these release carbon dioxide into the atmosphere. There are many causes for these energy shifts, called climate forcers; some internal in the climate itself, some natural but external to climate, and some man-made. The Earth's surface then gives off heat (long-wave radiation). A hefty slice of global greenhouse gas emissions come from the burps and farts of livestock. Climate change is one of the biggest issues affecting the world today. The first element, on the science of climate change, released in February, concluded it was at least 90% likely that human activities are principally responsible for the warming observed since 1950. Climate change can cause new patterns of pests and diseases to emerge, affecting plants, animals and humans, and posing new risks for food security, food safety and human health. We know that climate change is happening – but there are plenty of things individuals can do to help mitigate it. Volcanic activity - during a volcanic eruption carbon dioxide is released into the atmosphere, this can also affect sea-ice and ocean currents. Climate is a major driver of conflict across Africa, researchers say, with future warming likely to increase civil wars by 50% in 20 years. - when the waste decomposes it produces methane. … The atmosphere allows the heat from the Sun (short-wave radiation) to pass through to heat the Earth's surface. Burning coal, oil and gas produces carbon dioxide and nitrous oxide. If there is high amount emitted there will be an increase in Earth's temperatures.
