Environmental Topics; Laws & Regulations; Menu For example, American lobster, red hake, and black sea bass in the Northeast have moved northward by an average of 119 miles. Learn more », The populations of some marine species are shifting to more northerly waters since the 1960s.Learn more ». March sea ice extent reached a new low in 2015 and hit roughly the same low again in 2016—about 7 percent less than the 1981–2010 average. 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 average length of the growing season for crops in the contiguous 48 states has increased by nearly two weeks since the beginning of the 20th century. 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. Ocean heat content not only determines sea surface temperature, but also affects sea level and currents. Water levels in lakes are influenced by water temperature, which affects evaporation rates and ice formation. Data sources: World Resources Institute, 2014; Food and Agriculture Organization, 2014. The annual minimum extent of Arctic sea ice has decreased over time, and in September 2012 it was the smallest ever recorded. Some of these health impacts are already happening in the United States. The warming effect associated with carbon dioxide alone increased by 30 percent. The scientific information and tools can be used by communities to effectively and sustainably manage the impacts from a changing world. Lakes in the northern United States are freezing later and thawing earlier compared with the 1800s and early 1900s. What is climate change? Annual heat-related hospitalization rates ranged from fewer than one case per 100,000 people in some states to nearly four cases per 100,000 in others. This section of the report helps to illustrate how climate change can affect human health, and demonstrates how EPA’s climate change indicators advance the dialogue in connecting climate change and human health. Three independent analyses show that the amount of heat stored in the ocean has increased substantially since the 1950s. Slight increases in Antarctic sea ice are outweighed by the loss of sea ice in the Arctic during the same time period. searchable inventory offers freely available models, tools, and databases. This page provides a framework for displaying NCEA EIMS records. Comprehensive information from U.S. EPA on issues of climate changeglobal warming, including climate change science, greenhouse gas emissions data, frequently asked questions, climate change impacts and adaptation, what EPA is doing, and what you can do. Contact Us to ask a question, provide feedback, or report a problem. President-elect Joe Biden will make combatting climate change a top priority, calling it “an existential threat." 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. A particularly large and steady increase has occurred over the last 30 years. Changes in sea level relative to the land vary by region. Within the United States, temperatures in parts of the North, the West, and Alaska have increased the most. Freeze dates have shifted later at a rate of roughly half a day to one-and-a-half days per decade, while thaw dates for most of the lakes studied have shifted earlier at a rate of half a day to two days per decade. 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. Advertisement. Tick habitat and populations are influenced by many factors, including climate. Higher acidity affects the balance of minerals in the water, which can make it more difficult for certain marine animals to build their protective skeletons or shells. The EPA’s industry-friendly climate rule for power plants violates federal law, the D.C. Biden's nominees include North Carolina regulator Michael Regan as EPA administrator and Rep. Deb Haaland to head the Interior Department. Data sources: O’Neel et al., 2014; USGS, 2015. The occurrence of abnormally high annual precipitation totals has also increased. EPA research improves knowledge of the impacts of climate change on human health and the environment. But when President Donald Trump took office in 2017, everything changed at the EPA. The September maximum extent reached the highest level on record in 2014—about 7 percent larger than the 1981–2010 average. Read More The report summarizes years of work by scores of scientists as part of the EPA’s Climate Change Impact and Risk Analysis. Data source: Compilation of 10 underlying datasets. The Earth's climate is changing. Heating and cooling degree days measure the difference between outdoor temperatures and the temperatures that people find comfortable indoors. Main menu. Lyme disease is most common in the Northeast and the upper Midwest, where some states now report 50 to 100 more cases of Lyme disease per 100,000 people than they did in 1991. Glaciers in the United States and around the world have generally shrunk since the 1960s, and the rate at which glaciers are melting has accelerated over the last decade. T he head of the Environmental Protection Agency (EPA) defended big energy infrastructure projects and said Thursday that climate change is not his highest priority.. EPA must consider the potential impacts of a changing climate on the proposal, and the potential contribution the proposal will have to the state's greenhouse gas emissions.
