What is the summary of climate change?

The Short Answer: Climate change describes a change in the average conditions — such as temperature and rainfall — in a region over a long period of time. NASA scientists have observed Earth’s surface is warming, and many of the warmest years on record have happened in the past 20 years.

What is the evidence of climate change?

Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that Earth’s climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks.

What is the conclusion of climate change?

Impacts of climate change are occurring now Nevertheless, the conclusion is that natural systems around the world are being affected by regional climate changes, particularly temperature increases, and that these temperature increases are very likely to be the result of anthropogenic emissions of greenhouse gases.

What research is needed for climate change?

The last National Climate Assessment report, released by the U.S. Global Change Research Program (USGCRP) in 2009, recommended research on: 1) climate change impacts on ecosystems, the economy, health, and the built environment; 2) projections of climate change and extreme events at local scales; 3) decision-relevant …

What does climate change cause?

Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. Burning fossil fuels produces carbon dioxide, a greenhouse gas. It is called a greenhouse gas because it produces a “greenhouse effect”.

Which is the strongest evidence for climate change?

Scientists say the accumulation of heat in the oceans is the strongest evidence of how fast Earth is warming due to heat-trapping gases released by the burning of fossil fuels.

What are some possible solutions to climate change?

The main ways to stop climate change are to pressure government and business to:

• Keep fossil fuels in the ground.
• Invest in renewable energy.
• Switch to sustainable transport.
• Help us keep our homes cosy.
• Improve farming and encourage vegan diets.
• Restore nature to absorb more carbon.
• Protect forests like the Amazon.

What are the 5 causes of climate change?

Causes for rising emissions

• Burning coal, oil and gas produces carbon dioxide and nitrous oxide.
• Cutting down forests (deforestation).
• Increasing livestock farming.
• Fertilisers containing nitrogen produce nitrous oxide emissions.
• Fluorinated gases are emitted from equipment and products that use these gases.
