Climate-Resilient Rice Empowers Rural Gambia Since joining Maruo Farms, a local rice production company in Gambia, Mariam's life has improved and she no longer struggles to make ends meet. She now recruits and supervises women farmers. She is proud to be part of the team working to make positive impact in rural Gambia. Learn how production of climate-resilient rice for the Gambian market is changing the lives of women and vulnerable groups. Climate action starting now Everyone has a role in climate action. At the United Nations, we are calling on people everywhere to work together to solve climate challenges and realize the commitments of the 2015 Paris Agreement. This website keeps up with actions taken by governments, businesses, civil society, youth and more in every part of the world. It’s our planet, and while we know it is in crisis, we also know that solutions are in reach. Progress is already well underway, from more green energy to more secure food supplies. And the benefits are clear as well, such as green jobs, clean air and sounder economies. A more sustainable, prosperous world is in reach. Join us in taking action to claim it, starting now.

Fossil fuels – coal, oil and gas – are by farthe largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions. As greenhouse gas emissions blanket the Earth, they trap the sun’s heat. This leads to global warming and climate change. The world is now warming faster than at any point in recorded history. Warmer temperatures over time are changing weather patterns and disrupting the usual balance of nature. This poses many risks to human beings and all other forms of life on Earth. Generating power Generating electricity and heat by burning fossil fuels causes a large chunk of global emissions. Most electricity is still generated by burning coal, oil, or gas, which produces carbon dioxide and nitrous oxide – powerful greenhouse gases that blanket the Earth and trap the sun’s heat. Globally, a bit more than a quarter of electricity comes from wind, solar and other renewable sources which, as opposed to fossil fuels, emit little to no greenhouse gases or pollutants into the air. Manufacturing goods Manufacturing and industry produce emissions, mostly from burning fossil fuels to produce energy for making things like cement, iron, steel, electronics, plastics, clothes, and other goods. Mining and other industrial processes also release gases, as does the construction industry. Machines used in the manufacturing process often run on coal, oil, or gas; and some materials, lik...

At the root of climate change is the phenomenon known as the But beginning in the mid- to late-19th century, human activity began pushing the greenhouse effect to new levels. The result? A planet that’s warmer right now than at any other point in human history, and getting ever warmer. This Detailing and discussing the human causes of climate change isn’t about shaming people, or trying to make them feel guilty for their choices. It’s about defining the problem so that we can arrive at effective solutions. And we must honestly address its origins—even though it can sometimes be difficult, or even uncomfortable, to do so. Human civilization has made extraordinary productivity leaps, some of which have led to our currently overheated planet. But by harnessing that same ability to innovate and attaching it to a renewed sense of shared responsibility, we can find ways to cool the planet down, Here’s a rough breakdown of the factors that are driving climate change. Some amount of climate change can be attributed to natural phenomena. Over the course of Earth’s existence, But climate records are able to show that today’s global warming—particularly what has occured since the start of the industrial revolution—is happening much, much faster than ever before. According to anthropogenic, which is just a way of saying “caused by human beings.”) The unchecked burning of fossil fuels over the past 150 years has drastically increased the presence of atmospheric greenhouse gases, most n...

For Since the The source of these emissions vary, consisting of a mix of gases that include methane and carbon dioxide. While some How do greenhouse gases contribute to global warming? Greenhouse gases are made of molecules that absorb electromagnetic radiation, such as the light reflecting from the planet's surface, and reemit it as heat. These gases include methane, carbon dioxide, water, and nitrous oxide. Despite making up only a small percentage of the atmosphere's mix of gases they are very important. If we had no naturally occurring greenhouse gases in the atmosphere at all, the Carbon dioxide levels have steadily risen over the past two centuries, thanks largely to the burning of fossil fuels for electricity general, transportation, and smelting. Current levels are approximately This has so far seen an increase in average global temperatures over the past half century of just one one degree. Models vary in their predictions of further temperature increases, and depend heavily on future trends in greenhouse gas emissions. Conservative estimates by the Intergovernmental Panel on Climate Change predict an even chance of 4 degrees Celsius rise by the end of the century if current emissions trends continue.

Carbon emissions from fossils fuels like these have been linked to global warming and climate change. Photograph by Mark Thiessen / National Geographic Climate is sometimes mistaken for weather. But climate is different from weather because it is measured over a long period of time, whereas weather can change from day to day, or from year to year. The climate of an area includes seasonal temperature and rainfall averages, and wind patterns. Different places have different climates. A desert, for example, is referred to as an arid climate because little water falls, as rain or snow, during the year. Other types of climate include tropical climates, which are hot and humid, and temperate climates, which have warm summers and cooler winters. Climate change is the long-term alteration of temperature and typical weather patterns in a place. Climate change could refer to a particular location or the planet as a whole. Climate change may cause weather patterns to be less predictable. These unexpected weather patterns can make it difficult to maintain and grow crops in regions that rely on farming because expected temperature and rainfall levels can no longer be relied on. Climate change has also been connected with other damaging weather events such as more frequent and more intense hurricanes, floods, downpou...
