Since 1983, the United States has had an average of 72,000 recorded wildfires per year. Most climate change models predict extreme weather events like wildfires, droughts, and intense hurricane w… The annual minimum extent of Arctic sea ice has decreased over time, and in September 2012 it was the smallest ever recorded. Observations of lilacs and honeysuckles in the contiguous 48 states suggest that first leaf dates and bloom dates show a great deal of year-to-year variability. EPA establishes partnerships, provides leadership, and shares technical expertise to support these activities. The Climate Change Act 2017 also requires EPA to consider climate change in relation to a range of decisions including the issue of works approvals and licences. EPA is engaged in a variety of international activities to advance climate change science, monitor our environment, and promote activities that reduce greenhouse gas emissions. However, the most recent levels are all within the range of historical variation. Changes in sea level relative to the land vary by region. Since the 1970s, unusually hot summer temperatures have become more common in the United States while unusually cold winter temperatures have become less common—particularly very cold nights (lows). The scientific information and tools can be used by communities to effectively and sustainably manage the impacts from a changing world. One important way to track and communicate the causes and effects of climate change is through the use of indicators. EPA is working to protect the health and welfare of Americans through common sense measures to reduce greenhouse gas pollution and to help communities prepare for climate change. The incidence of West Nile virus neuroinvasive disease in the United States has varied widely from year to year and among geographic regions since tracking began in 2002. Within the United States, temperatures in parts of the North, the West, and Alaska have increased the most. One reason for this decline is that nearly 80 percent of the locations studied have seen a decrease in the proportion of precipitation falling as snow each winter. Explore the indicators below.

As climate change continues bearing down, observers say the EPA’s censorship is not only making it harder to create informed policy, it’s also possibly threatening lives. The rate is accelerating in many locations along the East and Gulf coasts. United States Environmental Protection Agency. Lakes in the northern United States are freezing later and thawing earlier compared with the 1800s and early 1900s. Tick habitat and populations are influenced by many factors, including climate. The indicators are published in EPA's report, Climate Change Indicators in the United States, available on this website and in print. President-elect Joe Biden will make combatting climate change a top priority, calling it “an existential threat." This interference is resulting in increased air and ocean temperatures, drought, melting ice and snow, rising sea levels, increased rainfall, flooding and other influences. Current and future emissions will continue to increase the levels of these gases in our atmosphere for the foreseeable future. Many of these observed changes are linked to the rising levels of carbon dioxide and other greenhouse gases in our atmosphere, caused by human activities. Temperature has risen by an average of 1.2°F across all sites and 2.2°F at the sites where trends were statistically significant. However, specific trends vary by region. Total snowfall—the amount of snow that falls in a particular location—has decreased in most parts of the country since widespread records began in 1930. Changes in temperature, precipitation, snowpack, and glaciers can affect the rate of streamflow and the timing of peak flow. Climate Change Adaptation Technical Fact Sheet: Contaminated Sediment Remedies In June 2014, the U.S. Environmental Prot ection Agency (EPA) released the final U.S. Environmental Protection Agency Climate Change Adaptation Plan.1 The plan examines how EPA programs may be vulnerable to a changing climate and how the Agency Warmer temperatures and later fall frosts allow ragweed plants to produce pollen later into the year, potentially prolonging the allergy season for millions of people. Three independent analyses show that the amount of heat stored in the ocean has increased substantially since the 1950s. For each … Average global temperatures show a similar trend, and all of the top 10 warmest years on record worldwide have occurred since 1998. EPA research improves knowledge of the impacts of climate change on human health and the environment. However, shifting weather patterns have caused certain areas, such as the American Southwest, to experience less precipitation than usual. Lyme disease is a bacterial illness spread by ticks that bite humans. Since 1995, average surface water temperatures have increased slightly for each of the Great Lakes. Almost all of this increase is attributable to human activities. The ocean has become more acidic over the past few centuries because of increased levels of atmospheric carbon dioxide, which dissolves in the water. Changes in the frequency and magnitude of river flood events vary by region. Even with some year-to-year variation, the overall increase is clear, and sea surface temperatures have been consistently higher during the past three decades than at any other time since reliable observations began in the late 1800s. The Mid-Atlantic region suffers the highest number of coastal flood days and has also experienced the largest increase in frequency over time. Leaf and bloom events are generally happening earlier throughout the North and West but later in much of the South. EPA partners with more than 40 data contributors from various government agencies, academic institutions, and other organizations to compile a key set of indicators related to the causes and effects of climate change. Long-term studies have found that bird species in North America have shifted their wintering grounds northward by an average of more than 40 miles since 1966, with several species shifting by hundreds of miles. EPA's updated Climate Change Indicators in the United States report presents evidence that climate change is already affecting our atmosphere, weather, oceans, ecosystems, and society. Tropical storm activity in the Atlantic Ocean, the Caribbean, and the Gulf of Mexico has increased during the past 20 years. There has been much year-to-year variability, however. What is climate change? Average drought conditions across the nation have varied since records began in 1895. From 1960 through 2014, water temperature increased at 79 percent of the stream sites measured in the region. A particularly large and steady increase has occurred over the last 30 years. Stormwater Management in Response to Climate Change Impact EPA and NOAA have led workshops and other community efforts across the Chesapeake Bay and Great Lakes regions to discuss how projected land use and climate change could impact local water conditions. Water levels in lakes are influenced by water temperature, which affects evaporation rates and ice formation. An increase in the atmospheric concentrations of greenhouse gases produces a warming effect over time. This page provides a framework for displaying NCEA EIMS records. Climate Change: EPA - Environmental Protection Agency, Ireland Climate Change. The area covered by ice is typically smallest in September, after the summer melting season. Antarctic sea ice extent in September and February has increased somewhat over time. What’s different about this period of the earth’s history is that human activities are significantly contributing to natural climate change through our emissions of greenhouse gases. Main menu. Of the 10 years with the largest acreage burned, nine have occurred since 2000, with many of the largest increases occurring in western states. No obvious long-term trend can be detected using available data. The rate of increase has accelerated in recent years to more than an inch per decade. The Environmental Protection Agency is creating higher barriers for regulating the emissions that contribute to climate change, setting new rules that effectively block the federal government from imposing new restrictions on several heavy industries. Data sources: World Resources Institute, 2014; Food and Agriculture Organization, 2014. This week EPA released a final report containing findings from these workshops.
