Global average temperature has risen by approximately 1°C since the late 19th century
Global weather patterns change over time, driven by natural and human factors. The long-term measurement of weather in a region is known as its climate. The Earth's climate is currently warming, primarily due to the increase in atmospheric carbon dioxide and methane emitted by human activities such as the use of fossil fuels for energy. Changes to the climate are likely to result in disruptions to water resources, ecosystems and crop yields, as well as increased climate-related extremes, vulnerability of marginalised populations and sea level rise. To avoid the worst impacts, significant efforts are underway to harness energy in ways that reduce emissions of greenhouse gases. Since 1992, most countries have been part of the United Nations Framework Convention on Climate Change, a treaty providing a framework for international cooperation for combating climate change.
