The impacts of human-induced climate change are increasing nationwide. Southeast. The official website for NASA's fleet of Earth science missions that study rainfall and other types precipitation around the globe. How much do you know about Earth's water cycle and the crucial role it plays in our climate? This buildup of CO2 leads to one of most obvious impacts of climate change: a hotter world. Because human-induced warming is superimposed on a naturally varying climate, the temperature rise has not been, and will not be, uniform or smooth across the country or over time. Global Change Research Program: Northeast. "Taken as a whole," the IPCC states, "the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time." Some existing health threats will intensify and new health threats will … For example, many natural ecosystems are already subject to urban encroachment, fragmentation, deforestation, invasive species, introduced pathogens and pressure on water resources. Furthermore, small changes in temperature correspond to enormous changes in the environment. An indicator of current global sea level as measured by satellites; updated monthly. Loosely defined, climate … The impacts of climate change include warming temperatures, changes in precipitation, increases in the frequency or intensity of some extreme weather events, and rising sea levels. Impacts from climate change are happening now. Projected impact of climate change on yields of corn, wheat, soybeans and cotton by the years 2080-2099. It is projected to rise another 1 to 8 feet by 2100. Changes in the timing of streamflow reduce water supplies for competing demands. Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves. The intensity, frequency and duration of North Atlantic hurricanes, as well as the frequency of the strongest (Category 4 and 5) hurricanes, have all increased since the early 1980s. Earth's climate record, preserved in tree rings, ice cores, and coral reefs, shows that the global average temperature is stable over long periods of time. Extreme heat will affect health, energy, agriculture and more. Two degrees may sound like a small amount, but it's an unusual event in our planet's recent history.
