Infrastructure and transportation are at risk.
Global climate change has already had observable effects on the environment.More nasa: What are the chances of another Hurricane Katrina?Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.Warmer freshwater makes it easier for disease-causing agents (such as bacteria) to grow and contaminate drinking water.Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner.Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires.However, based on the published literature, the impacts have not yet become established trends.Arctic sea ice extent both affects and is affected by global climate change.This is the result of added water from melting land ice and the expansion of seawater as it warms.Summer temperatures are projected to continue rising, and a reduction of soil moisture, which exacerbates heat waves, is projected for much of the western and central.S.Coral reefs are highly sensitive to small changes in ocean temperatures.Arctic likely to become ice-free The Arctic Ocean is expected to become essentially ice free in summer before mid-century.Forests are more prone to deadly infestations.More, visualization comparing 1950s and 1920s, this nasa visualization presents observational evidence that the growing season (climatological spring) is occurring earlier in the Northern Hemisphere.Many states and cities are beginning to incorporate climate change into their planning.Wgii.3,.2,.2, SPM, there is high confidence, based on substantial new evidence, that observed changes in marine and freshwater biological systems are associated with rising water temperatures, as well as related recits coquin changes in ice cover, salinity, oxygen levels and circulation.Smog irritates lungs and triggers asthma attacks.That assessment concluded that there is high confidence that recent regional changes in temperature have had discernible impacts on physical and biological systems.
The quality of the data sets has also improved.
Hurricanes will become stronger and more intense.
According to the ipcc, the extent of climate change effects on individual regions will vary over time and with the ability of different societal and environmental systems to mitigate or adapt to change.
