Pacific decadal oscillation to The ocean and atmosphere can work together to spontaneously generate internal climate variability that can persist for years to decades at a time. For example, alterations to ocean processes such as thermohaline circulation play a key role in redistributing heat in the world's oceans.
Learn about the causes of climate change and how you can reduce its threat. Share Climate change Climate change is the rise in average surface temperatures on Earth, mostly due to the burning of fossil fuels.
Say Hello to the New Face of Climate Change Climate change, Climate change called global warming, refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which releases carbon dioxide and other greenhouse gases into the air.
The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, including rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires.
Is climate change real? There is broad-based agreement within the scientific community that climate change is real. Environmental Protection Agency, the National Aeronautics and Space Administration, and the National Oceanic and Atmospheric Administration concur that climate change is indeed occurring and is almost certainly due to human activity.
What are the causes of climate change? The primary cause of climate change is the burning of fossil fuels, such as oil and coal, which emits greenhouse gases into the atmosphere—primarily carbon dioxide.
Other human activities, such as agriculture and deforestation, also contribute to the proliferation of greenhouse gases that cause climate change. Today it is at about ppm, a level not reached in more thanyears. Increased burning of fossil fuels contributes to climate change. Rising sea levels due to the melting of the polar ice caps again, caused by climate change contribute to greater storm damage; warming ocean temperatures are associated with stronger and more frequent storms; additional rainfall, particularly during severe weather events, leads to flooding and other damage; an increase in the incidence and severity of wildfires threatens habitats, homes, and lives; and heat waves contribute to human deaths and other consequences.
While the latter is generally true, decades of data and analysis support the reality of climate change—and the human factor in this process. In any case, economists agree that acting to reduce fossil fuel emissions would be far less expensive than dealing with the consequences of not doing so.

The Earth has warmed by an average of 1°C in the last century, and although that might not sound like much, it means big things for people and wildlife around the globe.

Our goals are to promote public understanding of climate science and climate-related events, to make our data products and services easy to access and use, to provide climate-related support to the private sector and the Nation’s economy, and to serve people making.
Climate change, periodic modification of Earth’s climate brought about as a result of changes in the atmosphere as well as interactions between the atmosphere and various other geologic, chemical, biological, and geographic factors within the Earth system.
The atmosphere is a dynamic fluid that is continually in motion. About climate change Tackling climate change is a priority for us and we're working hard to protect fish, farms, and waters from the damage that rising temperatures and shifting precipitation patterns will . The threats of climate change are real, but the solutions are now.
Climate change may be the most important challenge humanity has ever faced. But together, we all are part of the solution. The Nature Conservancy is a nonprofit, tax-exempt charitable organization (tax identification number ) under Section (c)(3) of the Internal.
