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. Cutting down forests (deforestation). (And Do They Mate With Other Species), Causes and Effects of Marine Habitat Loss, 35+ Outstanding Facts About the Planet Earth, Advantages and Importance of Reforestation, Five Different Atmospheric Layers of the Earth, Causes and Effects of Ozone Layer Depletion, Extraordinary Ways to Protect Coral Reefs, Causes and Effects to Environmental Pollution, Causes and Effects of Ocean Acidification. So much heat that many municipalities are working to try and harness that heat as power for their cities. There should be a global standard of living that everyone can achieve, but as a world society, we have to agree that enough is enough with excess. Most Americans recognize climate change, but some are still unsure about its causes. Pollution from cars and planes realeases CO2 into the air and the use of electricty to run the homes and businesses creates greenhouse gases. We're the ones who burn fossil fuels, produce livestock and clear trees, increasing the amount of heat-trapping gases in … Global warming is the most common term that comes up when we talk about climate change or pollution. 1. It provides a full introduction to the fundamentals of climate science and illustrates to students why current warming is not the result of natural processes. Human activity is driving climate change, including global temperature rise. To stop deforestation we would have to truly change our consumption habits. Milankovitch cycles over the past 1 000 000 years. Orbital Changes. It goes beyond just denying that it exists and extends into believing that it doesn’t really matter because global warming is a natural process the Earth recovers from. Volcanic Activity; Volcanic activity is well known to change the climate. That way you can make more informed choices in your life, but you can also educate other people. Major scientific assessments also agree. People living there often depend heavily on their natural environment and they have the least resources to cope with the changing climate. Overpopulation is yet another cause of global warming. The second stage of the oscillation brings about the opposite effect. 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. ~ David Suzuki. When she is not writing, she loves watching sci-fi movies on Netflix. U.S. Not all atmospheric gases are greenhouse gases; oxygen and nitrogen, for example, have no bearing on the greenhouse effect. As urban areas grow, so will the number of heat islands, which will drive up the overall atmospheric temperature. The Intergovernmental Panel on Climate Change defines climate change as: The causes of climate change can be any combination of: 1. Causes of climate change. Natural changes in the Sun and Earth cannot explain today’s global warming. Between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress. It is much easier to document the evidence of climate variability and past climate change than it is to determine their underlying mechanisms. Humans have increased atmospheric CO 2 concentration by 47% since the Industrial Revolution began. Changing air pressure patterns in the northern hemisphere causes arctic oscillation. 2. As our populations increase and our cities reach maximum capacity, we start to expand them in what is called urban sprawl. This shifting of large landmasses changed ocean current flow and winds and altered the atmosphere. more . Facts on climate change. El Nino raises global temperatures whereas La Nina decreases it. Moreover, while carbon dioxide is released into the air, its amounts are minimal and the aerosols released into the air actually serve to cool the Earth down by blocking sunlight. The PowerPoint is clearly structured with; - A starter to assess prior knowledge - focus here is on natural causes of climate change, then after the introduction of learning objectives another to assess prior knowledge of human causes of climate change. Trucks, cars, ships, planes, trains and anything else that you can think of that uses an engine driven by fossil fuel is the second greatest cause of global warming. It is present in the atmosphere and has a strong effect on weather and climate. 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. Livestock farming also releases large amounts of methane into the air, driving up the amount of greenhouse gases already in the atmosphere. While the loss in terms of money can be compensated but its environmental effects pose a huge danger to this planet. Climate change is the human activities that … The water surface of the eastern Pacific heats up while the water surface of the western Pacific cools down. Greenhouse gases occur naturally in the atmosphere and they serve to absorb and radiate the Sun’s heat around the globe for the benefit of life. Gavin Schmidt, director of National Aeronautics and Space Administration’s Goddard Institute for Space Studies, said that scientists look at a lot of different things at once.
