Mar 28, 2022 · 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.
Here are 10 ways you can be part of the climate solution: 1. Spread the word. Encourage your friends, family and co-workers to reduce their carbon pollution. Join a global movement like Count Us In, which aims to inspire 1 billion people to take practical steps and challenge their leaders to act more boldly on climate.
Jan 18, 2024 · In July, August, and September, global temperatures were more than 1.0°C (1.8°F) above the long-term average—the first time in NOAA's record any month has breached that threshold. Map of global average surface temperature in 2023 compared to the 1991-2020 average. Warmer-than-average areas are shades of red, and cooler-than-average areas ...
May 15, 2024 · Climate change describes a change in the average conditions — such as temperature and rainfall — in a region over a long period of time. For example, 20,000 years ago, much of the United States was covered in glaciers. In the United States today, we have a warmer climate and fewer glaciers. Global climate change refers to the average long ...
Apr 12, 2024 · Scientists have pieced together a record of the earth’s climate by analyzing a number of indirect measures of climate, such as ice cores, tree rings, glacier lengths, pollen remains, and ocean sediments, and by studying changes in the earth’s orbit around the sun. 2 This record shows that the climate varies naturally over a wide range of time scales, but this variability does not explain ...
Climate change is the result of the buildup of greenhouse gases in the atmosphere, primarily from the burning of fossil fuels for energy and other human activities. These gases, such as carbon dioxide and methane, warm and alter the global climate, which causes environmental changes to occur that can harm people's health and well-being.
