What is climate change?

What is climate change?
The climate has changed naturally throughout the Earth's history. But natural causes cannot explain the particularly rapid warming seen over the last century, according to the UN's climate body, the Intergovernmental Panel on Climate Change (IPCC). This has been caused by human activities, mainly the widespread use of fossil fuels - coal, oil and gas - in homes, factories and transport systems. When fossil fuels burn, they release greenhouse gases - mostly carbon dioxide (CO2). This CO2 acts like a blanket, trapping extra energy in the atmosphere near the Earth's surface. This causes the planet to heat up. Since the start of the Industrial Revolution - when humans started burning large amounts of fossil fuels - the amount of CO2 in the atmosphere has risen by about 50%, external, far above levels seen in the Earth's recent history. The CO2 released from burning fossil fuels, external has a distinctive chemical fingerprint.

Nos movemos para ir a trabajar, para ir a ver a los nuestros, para ir de vacaciones y para disfrutar de nuestro tiempo libre y aprender, pero depende de cual sea el sistema de transporte empleado, nuestra huella de carbono aumenta más o menos por cada kilómetro recorrido. Pero, ¿debemos ir cada día en coche a trabajar, o podemos ir en transportes menos contaminantes como los medios colectivos, a pie o en bici? Pese a que hay aspectos de nuestra movilidad que seguramente no podemos modificar (como el lugar de trabajo), seguramente hay algunas pautas de movilidad que podemos cambiar y, si no, tratar al menos de reducir sus emisiones. Se calcula que en el año 2050 seremos 10.000 millones de personas en la Tierra. Con esta calculadora de las emisiones del transporte puedes calcular las emisiones de CO2 asociadas a un desplazamiento cotidiano o puntual.

What is climate change: facts for kids We’ve all heard of it, but what is climate change and what is it doing to our planet? So, what is climate change? Climate change (or global warming), is the process of our planet heating up. Scientists estimate that since the Industrial Revolution, human activity has caused the Earth to warm by approximately 1°C. While that might not sound like much, it means big things for people and wildlife around the globe. Unfortunately, rising temperatures don’t just mean that we’ll get nicer weather – if only! As temperatures rise, some areas will get wetter and lots of animals (and humans!) Check out our magazine! National Geographic Kids is an exciting monthly read for planet-passionate boys and girls, aged 6-13! Packed full of fun features, jaw-dropping facts and awe-inspiring photos – it’ll keep you entertained for hours!

What is climate change? Climate change is any long-term alteration in average weather patterns, either globally or regionally. Climate change has occurred many times in Earth's history, and for many different reasons. The changes in global temperature and weather patterns seen today, however, are caused by human activity. And they're happening much faster than the natural climate variations of the past. Scientists have many ways to track climate over time, all of which make it clear that today's climate change is linked to the emission of greenhouse gases, such as carbon dioxide and methane. On average, the effect of greenhouse gases is to increase global temperatures. "It's important for people to realize that there is a lot of variability from place to place on the Earth in terms of the temperature," said Ellen Mosley-Thompson, a paleoclimatologist at the Byrd Polar and Climate Research Center of The Ohio State University. How do scientists know climate change is real? How is the climate changing? Bibliography

Climate change: 'Adults need to do more!' - CBBC Newsround Getty Images A Newsround survey reveals more than half of children think adults aren't doing enough to protect the environment. Nowadays, lots of us are trying our best to help look after the planet, from using fewer plastic bottles to ditching the car in favour of a bicycle. It's an issue that lots of young people are passionate about and something that gets plenty of you talking. To enjoy the CBBC Newsround website at its best you will need to have JavaScript turned on. Newsround's survey, carried out by ComRes, asked 2,000 children aged 8 to 16-years-old if they think adults do enough to protect the environment? Fifty-three per cent say grown-ups aren't doing enough. Older teens feel even more strongly about the issue, with 61% of 14 to 16-year-olds telling us they think adults should do more. School children taking part in a climate change march in London earlier this year Since the start of the year hundreds of thousands of school children have taken part in climate change protests.

Water Pollution Facts, Types, Causes and Effects of Water Pollution To address pollution and protect water we need to understand where the pollution is coming from (point source or nonpoint source) and the type of water body its impacting (groundwater, surface water, or ocean water). Where is the pollution coming from? Point source pollution When contamination originates from a single source, it’s called point source pollution. Nonpoint source Nonpoint source pollution is contamination derived from diffuse sources. Transboundary It goes without saying that water pollution can’t be contained by a line on a map. What type of water is being impacted? Groundwater pollution When rain falls and seeps deep into the earth, filling the cracks, crevices, and porous spaces of an aquifer (basically an underground storehouse of water), it becomes groundwater—one of our least visible but most important natural resources. Surface water pollution Ocean water pollution

Gráficos para entender el cambio climático de un solo vistazo Una de las portadas de la revista The Economist de septiembre de 2019 incluye un gráfico de barras que muestra el aumento de la temperatura media global desde 1850 hasta 2018. La imagen también ha aparecido estos días en la primera página de la web del periódico The Guardian. Pero esta imagen creada por Ed Hawkins, profesor de Ciencias Climáticas en la Universidad de Reading (Reino Unido), se popularizó este verano en su cuenta de Twitter. En las distintas ilustraciones de su web Show your Stripes (Muestra tus barras), las líneas azules son los años en los que la temperatura media fue menor que la media del periodo entre 1850 y 2018. Otras representaciones visuales también han intentado que el mayor número de personas posible entienda la importancia del cambio climático.

12 Female Climate Activists Who Are Saving the Planet Why Global Citizens Should Care The United Nations argues that the world has less than 12 years to cut greenhouse gas emissions in half to avoid severe climate change consequences. All around the world, young activists are fighting to achieve this goal. You can join us in taking action on related issues here. For the past 30 years, environmental activists have been calling on governments to reduce greenhouse gas emissions to avoid catastrophic climate change. The world has less than 12 years to cut greenhouse gas emissions in half — a daunting task that would require a total transformation of the global economy — according to the United Nations. Yet even as the consequences of climate change become more stark with each passing year — floods and storms submerging coastlines more frequently, wildfires growing to new extremes, and droughts drying up critical sources of water — fossil fuel consumption continues to rise.

Ten Clear Indicators Our Climate is Changing Few global trends have been as controversial as climate change and the Earth’s warming. The Earth has gone through many shifts in cooling and warming driven by natural factors like the sun’s energy or variations in its orbit, but the trend scientists have seen over the past 50 years is unmistakable. Let’s take a closer look: globally, average surface temperatures increased 1.1—1.6 degrees Fahrenheit (0.6—0.9 degrees Celsius) between 1906 and 2005. However, it’s the rate of temperature change that’s especially troubling to scientists; temperatures have risen nearly twice as fast in the last 50 years alone. What other ways has our climate system changed in the last century? How do we really know our climate is changing permanently, rather than just going through a normal period of flux? So to help set the record straight, we’re going to focus on 10 major changes scientists have seen in our climate system. 1. 2. Oceans evaporate more water as the air right near the surface gets warmer. 3.

Climate change: What is it and why is everyone talking about it? - CBBC Newsround Getty Images What is climate change? A lot of people consider climate change the most important crisis that the world is facing today. But what is it? And why are so many scientists, campaigners and politicians concerned about its effects? It is a complicated issue - but a very important one. When we talk about climate change, we are talking about global changes in the Earth's average temperature. The Earth's average temperature moves up and down naturally, but it has been increasing more rapidly than it usually does. This change is impacting on the planet's environment - which is everything natural around us; rivers, trees, plants, animals... everything! What is causing the Earth's temperatures to rise? Scientists say many of the changes to the Earth's climate are caused by human activity - this means things that humans are doing. Some of those things are: Burning of oil, coal and gas - These resources are called fossil fuels - they are used to power factories, buildings and transportation.

10 things you can do to help save our planet One of the most efficient ways of lowering your environmental impact is by travelling responsibly. This means, whenever you can, choosing a more sustainable way to get from A to B - walk or cycle when you can. Transport is one of the most polluting sectors in the UK. But holidaying closer to home can make a big impact on your carbon footprint. One short haul return flight can account for 10% of your yearly carbon emissions, and long-haul flights can completely determine your carbon impact. If you have the time you can usually get trains to European destinations to cut your carbon footprint. If you do choose to go abroad and are looking to see the local wildlife, keep in mind how to go about it ethically.

Swiss artist Klaus Littman, who designed the installation, has called it For Forest - The Unending Attraction of Nature. People can visit it at Wörthersee Stadion in Klagenfurt. The forest was inspired by a drawing Littman came across by artist Max Peintner, which imagines a world in which nature is only seen in specific spaces like animals in zoos. Max Peintner Peintner's drawing imagines a world where nature is confined to certain spaces Littman said he wanted to take trees that people see every day and make people really notice them. He said: "This forces people to question things that surround them and that they take for granted - in this case trees." Ice Watch, London Getty Images Support, Venice Western Flag, London
