why is climate change important

Ecosystems are also affected by climate change. Scientists say recent extreme weather events were made more likely by human-caused climate change. Extreme weather events can compound many of these health threats. The arctic now traps or absorbs up to 25 percent of this gas but climate change could alter that amount, according to a study published in the November issue of Ecological Monographs. 10 reasons why we should all care about climate change, 1.

Flint, L.E., Flint, A.L., and Thorne, J.H., 2015, Climate change: evaluating your local and regional water resources: U.S. Geological Survey Fact Sheet 2014–3098, 6 p., http://dx.doi.org/10.3133/fs20143098. The wind farm “Los Granujales” in the South of Spain (Vejer de la Frontera, Cádiz). Greenhouse gases in the atmosphere absorb heat radiation. If you’re one of those people who need a coffee hit to get going, mornings may become grim. The report also highlights a number of climate change impacts that could be avoided by limiting global warming to 1.5ºC compared to 2ºC, or more. The report provides a comprehensive assessment of sea level rise, and its causes, over the past few decades. The U.S. Energy Information Administration estimates that in 2017, the United States emitted 5.1 billion metric tons of energy-related carbon dioxide , while the global emissions of energy-related carbon dioxide totaled 32.5 billion metric tons. U.S. Geological Survey (USGS) scientists who study trends in climate change will be presenting the results from new studies at a workshop held in Pacific Grove, California, May 13-16, 2007. Oakley, K., Atwood, T., Douglas, D., Rode, K., and Whalen, M., 2015, Changing Arctic Ecosystems—Updated forecast: Reducing carbon dioxide (CO2) emissions required to improve polar bear outlook: U.S. Geological Survey Fact Sheet 2015–3042, 2 p., http://dx.doi.org/10.3133/fs20153042. Seven in 10 Americans think the climate … What is the difference between weather and climate change? The site editor may also be contacted with questions or comments about this Open Educational Resource. Climate change is affecting the American people in far-reaching ways. - What are solar storms and are they. They really are amazing; the Amazon, for example, is home to an astonishing 1 in 10 of all the known species on Earth. At the 21st Conference of the Parties in Paris in 2015, Parties to the UNFCCC reached a landmark agreement to combat climate change and to accelerate and intensify the actions and investments needed for a sustainable low carbon future. One highly visible consequence has been a rapid decline in Arctic sea ice over the past 3 decades - a decline projected to continue and result in ice-free summers likely as soon as 2030. Did you know that 2 in every 3 people worldwide live in regions of severe water scarcity? We need your help to give rangers the strength and safety they need, and to tackle poaching and demand for products like ivory. The U.S. Geological Survey announced today that improved global topographic (elevation) data are now publicly available for North and South America, Pacific Islands, and northern Europe. There are now 197 Parties to the Convention and 192 Parties to the Kyoto Protocol. As a result, the ocean is becoming more acidic, affecting marine life. Questions include: America has questions about climate change, and the USGS has real answers. First, land cover--as shaped by land use practices--affects the global concentration of greenhouse gases. The cost and benefits of global warming will vary greatly from area to area.

The world’s oceans will warm and ice melt will continue. Atmospheric aerosols alter climate by scattering and absorbing solar and infrared radiation and they may also change the microphysical and chemical properties of clouds. Figure 1.2: Sea Level: Today vs. the Pleistocene Epoch -, From Meteorology to Mitigation: Understanding Global Warming, The Select Committee on Energy Independence and Global Warming, Overview of the Climate System - Part 1 ›, Lesson 1- Introduction to Climate and Climate Change. Yet over a third of the Amazon rainforest is already threatened by climate change. Instructor: Sonya Miller, Researcher, Department of Meteorology, College of Earth and Mineral Sciences, The Pennsylvania State University. We need all financial institutions, public and private, to choose, once and for all, the green economy.”, In 2007, the Nobel Peace Prize was awarded jointly to former United States Vice-President Al Gore and the IPCC "for their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change.". Human health is vulnerable to climate change. Has the USGS made any Biologic Carbon Sequestration assessments? Take a look at Figure 1.2 below, which indicates the Gulf coast continental outline near the height of the last Ice Age 18,000 years ago, vs. the current continental outline. But the larger the change in climate, the more negative the consequences will become. A hydrocarbon gas produced both through natural sources and human activities, including the decomposition of … Human activities that lead to carbon dioxide emissions come primarily from energy production, including burning coal, oil, or natural gas. In the Midwest and northeastern states, the frequency of heavy downpours has increased. Climate Data Records, as defined by the National Research Council, are a time series of measurements with sufficient length, consistency, and continuity to identify climate variability and change. Hurricanes and Climate Change Increasingly destructive hurricanes are putting a growing number of people and communities at risk.

Air pollution can lead to asthma, heart and lung disease. Without discussing global warming, people may never learn important facts about climate change, or that close friends and family care about the issue.” It’s worth emphasizing this last part. How much carbon dioxide does the United States and the World emit each year from energy sources? For moderate climate change, the balance can be difficult to assess. Join us and you can help stop the illegal wildlife trade and tackle other threats facing our natural world.
