Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, an increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regions. Below are some of the regional impacts of global change forecast by the Intergovernmental Panel on What is the difference between weather and climate change? Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time.

Climate change refers to long-term changes. How can climate change affect natural disasters? With increasing global surface temperatures the possibility of more droughts and increased intensity of storms will likely occur. As more water vapor is evaporated into the atmosphere it becomes fuel for more powerful storms to develop.

More heat in the atmosphere and warmer ocean surface temperatures can lead to increased wind speeds in tropical What are some of the signs of climate change? Does the USGS monitor global warming? Not specifically. Our charge is to understand characteristics of the Earth, especially the Earth's surface, that affect our Nation's land, water, and biological resources.

That includes quite a bit of environmental monitoring. How do changes in climate and land use relate to one another? The link between land use and the climate is complex.

First, land cover--as shaped by land use practices--affects the global concentration of greenhouse gases. Second, while land use change is an important driver of climate change, a changing climate can lead to changes in land use and land cover. For example, farmers might shift from their How do we know the climate is changing? The scientific community is certain that the Earth's climate is changing because of the trends that we see in the instrumented climate record and the changes that have been observed in physical and biological systems.

The instrumental record of climate change is derived from thousands of temperature and precipitation recording stations around the Will global warming produce more frequent and more intense wildfires? Hot, dry conditions, however, do not automatically mean fire—something needs to create the How does carbon get into the atmosphere?

Atmospheric carbon dioxide comes from two primary sources—natural and human activities. Natural sources of carbon dioxide include most animals, which exhale carbon dioxide as a waste product. Human activities that lead to carbon dioxide emissions come primarily from energy production, including burning coal, oil, or natural gas. Learn more The USGS is congressionally mandated Energy Independence and Security Act to conduct a comprehensive national assessment of storage and flux flow of carbon and the fluxes of other greenhouse gases including carbon dioxide in ecosystems.

At this writing, reports have been completed for Alaska , the Eastern U. How much carbon dioxide does the United States and the World emit each year from energy sources? Energy Information Administration estimates that in , the United States emitted 5.

Which area is the best for geologic carbon sequestration? However, the area of the assessment with the most storage potential for carbon dioxide is the Coastal Plains region, which includes coastal basins from Texas to Georgia. That region accounts for 2, metric Filter Total Items: Year Published: Monitoring and assessing urban heat island variations and effects in the United States Landsat surface temperature and land cover products have been used to estimate surface temperatures in urban and surrounding nonurban areas and to quantify urban heat island intensity.

Airplanes emit staggering amounts of CO 2 pollution — 11 percent of emissions from U. Learn about our campaign to hold the aircraft industry accountable. The Center pioneered the fight to save polar bears from global warming. Economic development and population growth are leading to greater meat and dairy consumption worldwide, making livestock a rising contributor to climate change.

There are ways to reduce greenhouse gas emissions from livestock operations, including capturing methane from manure and changing animal feeding practices. Rising global temperatures exacerbate heat-related diseases , such as heat exhaustion and heatstroke, as well as cardiovascular, respiratory, and kidney diseases.

Extreme heat kills about people in the United State every year. Since , more people have died of extreme heat in the United States than from cold snaps, floods, hurricanes, or tornadoes. Climate change also impacts food-borne diseases because higher temperatures can increase the abundance and range of many pathogens, as well as their growth rates and survivability.

Water availability and water-borne illnesses are also impacted by climate change. Regions that depend on snow melt for drinking water may have less available water, since less snow is accumulating during the winter. Increased flooding caused by extreme weather events can intensify water-borne diseases by providing standing water that acts as a breeding ground for insects. Flooding can also lead to more contaminated water that is unsafe to drink or bathe in.

Warmer temperatures have caused increased toxic algae blooms in lakes in some parts of the country. Changes in climate will also affect where disease vectors such as insects, snails, and other cold-blooded animals can live by extending or shifting their ranges and the length of the transmission season. Changes in seasonal weather patterns that farmers are accustomed to also make it more difficult for them to plan their plantings and harvests. Warming ocean temperatures are causing range shifts for fish and shellfish species, which, in turn, impact fisheries.

Though plants need carbon dioxide to grow, higher levels of carbon dioxide in the atmosphere are not necessarily beneficial for agriculture. Researchers have found that higher levels of carbon dioxide result in crops with lower nutritional value. A carbon footprint is the amount of carbon emitted by the actions of a person, group, household, organization, or activity over a given time period, primarily due to the consumption of fossil fuels.

The more fossil fuels are consumed during an activity, the larger the carbon footprint for example, flying results in a larger carbon footprint than taking a train to cover the same distance. Activities that are part of the natural carbon cycle, such as breathing, are not counted. A carbon footprint can also include emissions of other greenhouse gases, such as methane in which case, their contribution is usually calculated based on their carbon equivalent. Reducing or offsetting greenhouse gas emissions by improving energy efficiency, using renewable energy, and adopting sustainable practices is the best way to reduce one's carbon footprint.

Simple things like taking public transportation, using light emitting diode LED light bulbs, and reducing food waste are just a few of the many ways you can reduce your carbon footprint and fight climate change. Source: EIA Renewable sources of energy come from natural resources—like sunlight, plant matter biomass , geothermal activity, water, and wind—that are not depleted when used or can be regrown, in the case of plant matter. In contrast, nonrenewable sources of energy —like fossil fuels—are finite resources that cannot be easily replenished when consumed.

Renewable energy is also a low- or zero-carbon source of energy. Common sources of renewable energy are solar, wind, geothermal, and hydro power as well as certain forms of biomass. Renewable technologies like wind turbines and solar panels have become increasingly competitive in energy markets as their production costs continue to fall.

Renewable energy currently accounts for Increasing global investment in renewable energy technologies has been acknowledged by the overwhelming majority of climate change experts and world leaders to be an essential strategy for reducing greenhouse gas emissions. Energy efficiency means using less energy to perform the same task or eliminating energy waste. Energy efficiency brings a variety of benefits: reducing greenhouse gas emissions, reducing demand for energy imports, and lowering costs on a household and economy-wide level.

Improving energy efficiency is the cheapest—and often the most immediate—way to reduce the use of fossil fuels. There are enormous opportunities for efficiency improvements in every sector of the economy, whether it is buildings, transportation, industry, or energy generation. Climate adaptation means adjusting to the current and expected impacts of climate change. It can apply to habitats, but also to societies and economies. Adaptation usually involves preparing for harmful effects such as rising sea levels and more frequent and intense extreme weather , but it can also prepare communities to benefit from climate change opportunities.

Examples of climate adaptations include changing crop planting and harvesting patterns to align with a new climatic zone, moving homes away from a coastline or putting those homes on stilts, and planting trees in cities to decrease intense heat made worse by the urban heat island effect. Nature-based solutions are an important form of climate adaptation. Examples of nature-based solutions include the tree example above, green roofs which absorb storm water and reduce temperatures, and living shorelines that can absorb storm surge during extreme weather events.

Climate mitigation means reducing or stabilizing the level of greenhouse gases in the atmosphere. This can be done by removing carbon from the atmosphere, for example by expanding forested land, or by emitting fewer greenhouse gases. Resilience is the ability of a system to absorb, withstand, and bounce back after an adverse event. In an environmental context, it is the collection of policies, infrastructure, services, transportation, energy systems, and planning that positions communities to prepare for and respond to the impacts of climate change.

Communities that plan with resilience in mind are better able to adapt and thrive in the face of a changing climate. For the communities that are most vulnerable to climate impacts, planning for resilience can prevent displacement or facilitate planned relocation and reduce devastating financial losses and fatalities.

Resilience measures are starting to be including in policies and designs by U. Army Corps of Engineers. The leaders of the House of Representatives created the House Select Committee on the Climate Crisis to recommend climate policies, and House and Senate Standing Committees held at least hearings related to climate change and the environment in and at least 79 hearings in However, the legislative branch has yet to pass significant legislation that will reduce greenhouse gas emissions and enhance resilience to climate impacts.

Many states, including the 24 states that are members of the U. Climate Alliance , are moving forward with policies to curb carbon emissions and favor renewable energy and energy efficiency. As of July , 23 states and the District of Columbia have set their own greenhouse gas reduction targets.

Economic trends have also helped the United States reduce its carbon emissions. Natural gas and renewable energy have become much cheaper, and are increasingly being used to generate electricity instead of coal coal is a major source of carbon emissions. Thanks to this transition away from coal, U. The power sector has been replaced by the transportation sector as the largest source of U. But in November , the Trump Administration announced it was starting the process to withdraw the United States from the Paris Agreement—a step completed in November Investors and companies across the globe are embracing the shift from fossil fuels to cleaner energy.

Many large corporations have all stepped up to show their public support for U. More than 1, companies have signed a letter that endorses the Paris Agreement on climate change.

Moody's, whose ratings play an essential role in financial markets, now includes climate risk in its corporate ratings. During the annual Conference of the Parties COP , nations share information on emissions, policies, and practices, and attempt to develop strategies for addressing climate change.

The IPCC consults experts to assess climate change science and presents policy-relevant information outlining how nations can mitigate greenhouse gas emissions and adapt to the impact and risks of this global threat.
