Shifts have occurred among several economically important fish and shellfish species. Antarctic sea ice extent in September and February has increased somewhat over time. Other factors that affect the number of Lyme disease cases include changes in the populations of host species (particularly deer), which affect tick population size. B. Since 1979, more than 9,000 Americans were reported to have died as a direct result of heat-related illnesses such as heat stroke. 19911997 wildland fire statistics. 86(2):320327. Climate Change Indicators: Ocean Acidity This indicator describes changes in the chemistry of the ocean that relate to the amount of carbon dioxide dissolved in the water. Thus, with less than four decades of data shown here, it might be challenging to draw conclusions about long-term trends. Sci. Temperatures are rising, snow and rainfall patterns are shifting, and more extreme climate events like heavy rainstorms and record high temperatures are already happening. Since the 1970s, unusually hot summer temperatures have become more common in the United States while unusually cold winter temperatures have become less commonparticularly very cold nights (lows). Johnston, G. Pouliot, and A.G. Rappold. However, shifting weather patterns have caused certain areas, such as the American Southwest, to experience less precipitation than usual. One important way to track and communicate the causes and effects of climate change is through the use of indicators. This figure shows the total number of wildfires per year from 1983 to 2021. 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. Greenhouse gases from human activities are the most significant driver of observed climate change since the mid-20 th century. USGCRP (U.S. Learn more , The populations of some marine species are shifting to more northerlywaters since the 1960s.

Global Greenhouse Gas Emissions by Gas, 1990-2010 This figure shows worldwide emissions of carbon dioxide, methane, nitrous oxide, and several fluorinated gases from 1990 to 2010. In this map, warmer colors indicate an increase in temperatures, leading to less of a need to turn on the heatthat is, fewer heating degree days. 19. Changes in the frequency and magnitude of river flood events vary by region. Figure 1. Chapter 5: Vector-borne diseases. These maps focus on the parts of the United States where Lyme disease is most common. Concentrations of carbon dioxide and other greenhouse gases in the atmosphere have increased since the beginning of the industrial era. This figure shows the annual incidence of Lyme disease, which is calculated as the number of new cases per 100,000 people. From 2001 to 2010, a total of about 28,000 heat-related hospitalizations were recorded across 20 states. 4. 21. The report analyzes 24 key indicators that show how climate change impacts the health and environment across the nation. However, the most recent levels are all within the range of historical variation. Burned acreage in the West has increased noticeably in nearly every month of the year (see Figure 7). These data cover the contiguous 48 states. 2019. 11. Stewart, H. Cleveland, L. Bramwell, and V.C. Non-accidental health impacts of wildfire smoke. Cases are reported based on the patients county of residence, which is not necessarily the place where they were infected. Community Connection: Cherry Blossom Bloom Dates in Washington, D.C. The depth or thickness of snow on the ground (snowpack) in early spring decreased at more than 90 percent of measurement sites in the western United States between 1955 and 2016.

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. The warming effect associated with carbon dioxide alone increased by 30 percent. Web update: July 2022. Storm intensity is closely related to variations in sea surface temperature in the tropical Atlantic. 23. www.cdc.gov/media/releases/2013/p0819-lyme-disease.html. The ocean has become more acidic over the past few centuries because of increased levels of atmospheric carbon dioxide, which dissolves in the water. About EPA's Indicators. Int. Hyg. 11. The extent of area burned bywildfires each yearappears to have increased since the 1980s. Of the total area burned each year from 1984 to2020, the proportion of burned land suffering severe damage has ranged from 5 to 23percent (see "high" category inFigure 3). The annual minimum extent of Arctic sea ice has decreased over time, and in September 2012 it was the smallest ever recorded. R. Soc. Explore , U.S. wildfires burned more than 10 million acres in 2015, the largest annual amount of land burned since 1983. When averaged over all of the worlds oceans, sea level has risen at a rate of roughly six-tenths of an inch per decade since 1880. The data do not show an obvious trend during this time. climate change 2021 report. 22. The area covered by ice is typically smallest in September, after the summer melting season. Reidmiller, D.R., C.W. Water levels in lakes are influenced by water temperature, which affects evaporation rates and ice formation. 13. This chapter looks at some of the ways that climate change affects ecosystems, including changes in wildfires, streams and lakes, bird migration patterns, fish and shellfish populations, and plant growth. Global Change Research Program. A more focused analysis of drought in recent years shows that between 2000 and 2015, roughly 20 to 70 percent of the United States experienced drought at any given time.

Global Average Absolute Sea Level Change, 1880-2015 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. Kunkel, K.L.M. Wildfire Frequency in the United States, 1983-2021. Total snowfallthe amount of snow that falls in a particular locationhas decreased in most parts of the country since widespread records began in 1930. Host species populations and habitats can be affected by climate change and other ecosystem disturbances. In the United States, the snow cover season has become shorter by nearly two weeks on average since 1972. U.S. Of the 10 years with the largest acreage burned, nine have occurred since 2000, with many of the largest increases occurring in western states. Water levels in lakes are influenced by water temperature, which affects evaporation rates and ice formation. 2016. Flooding is becoming more frequent along the U.S. coastline as sea level rises. The EEA was established by the European Economic Community (EEC) Regulation 1210/1990 (amended by . Short, K.C. Longer-term climate patterns also play a role by creating conditions that may be conducive to wildfire (for example, a multi-year regional drought). 1 The indicators in this chapter characterize emissions of the major greenhouse gases resulting from human activities, the concentrations of these gases in the atmosphere, and how emissions and concentrations have changed over time. 8. NIFC (National Interagency Fire Center). Many environmental impacts associated with climate change can affect the severity and timing of the wildfire season, including changes in temperature, precipitation, and drought. MTBS (Monitoring Trends in Burn Severity). One important way to track and communicate the causes and effects of climate change is through the use of indicators.

The occurrence of abnormally high annual precipitation totals has also increased. The indicator describes two types of sea level changes: absolute and relative. Accessed 2019. Floods have generally become larger across parts of the Northeast and Midwest and smaller in the West, southern Appalachia, and northern Michigan. Global Change Research Program. 2022. These totals include all reported wildfires, which can be as small as just a few acres. The annual minimum extent of Arctic sea ice has decreased over time, and in September 2012 it was the smallest ever recorded. Data source: CDC, 201912 Whyte, and A.F. Gregory, A.F. Cooler colors indicate the opposite. As the U.S. climate has warmed in recent years, heating degree days have decreased and cooling degree days have increased overall, suggesting that Americans need to use less energy for heating and more energy for air conditioning.

Climate Change Indicators: Greenhouse Gases | US EPA This map shows how the number of acres burned in each state as a proportion of that states total land area has changed over time, based on a simple comparison between the first half of the available years (19842001) and the second half (20022020). 2016. When they burn, they immediately release carbon dioxide into the atmosphere, which in turn contributes to climate change. U.S. A few states did not have any fires that were large enough to be included in this analysis. Changes in temperature, precipitation, snowpack, and glaciers can affect the rate of streamflow and the timing of peak flow. Garofalo, M. Hahn, M. Hayden, A.J. This map shows how reported Lyme disease incidence has changed by state since 1991, based on the number of new cases per 100,000 people.

Quadrennial fire review. what are countries doing about climate change 2022 2018. Along the U.S. coastline, sea level has risen the most along the Mid-Atlantic and Gulf coasts, in some places by more than 8 inches since 1960. From 1960 through 2014, water temperature increased at 79 percent of the stream sites measured in the region. Ecol. This indicator defines a wildfire as "a wildland fire originating from an unplanned ignition, such as lightning, volcanos, unauthorized and accidental human caused fires, and prescribed fires that are declared wildfires.17 This indicator tracks four aspects of wildfires over time: the total number of fires (frequency), the total land area burned (extent), the degree of damage that fires cause to the landscape (severity), and the acreage burned by fires starting in each month of the year (seasonal patterns). Stewart, and T.K. Official websites use .gov These species also moved an average of 20 feet deeper. The average portion of North America covered by snow has decreased at a rate of about 3,300 square miles per year since 1972, based on weekly measurements taken throughout the year. Lyme disease is the most common vector-borne disease (that is, a disease transmitted by mosquitoes, ticks, or fleas) in the United States. Along the U.S. coastline, sea level has risen the most along the Mid-Atlantic and Gulf coasts, in some places by more than 8 inches since 1960. Concentrations of carbon dioxide and other greenhouse gases in the atmosphere have increased since the beginning of the industrial era. Kersh, H. Hooks, S.K. Barker, J.F. 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. Explore Climate Change Indicators Drought Oceans Summary Ocean Heat Sea Surface Temperature Sea Level Coastal Flooding Ocean Acidity Glaciers Lake Ice Along with the influence of ongoing climate change, wildfire patterns can be influenced by natural climate cycles that tend to shift every few decades.
