Effects of global warming
Apr 15, · The Effects of Climate Change Future Effects. Global climate is projected to continue to change over this century and beyond. The magnitude of climate Temperatures Will Continue to Rise. Because human-induced warming is superimposed on a naturally varying climate, the Changes in . Apr 19, · That’s why “global warming” is a bit of an oversimplification. Instead, some scientists have suggested that the phenomenon of human-caused climate change would more aptly be called.
The potential future effects of global climate change include more frequent wildfires, longer periods of drought in some regions and an increase in the number, duration and intensity of tropical storms. Global climate change has already had observable effects on the environment.
Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. Effects what shoes to wear without socks scientists had predicted in the past would result from global climate how to upload web pages to google sites are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves.
Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. 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. The IPCC predicts that increases in global mean temperature of less than 1.
Net annual costs will increase over time as global temperatures increase. Some of the long-term effects of global climate change effecst the United States are as follows, according to the Third and Fourth National Climate Assessment Reports:.
Global climate is projected to continue to change over this century and beyond. Go backward and forward in time with this interactive visualization that illustrates how the Earth's climate has changed in recent history. Because human-induced warming effeects 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. The length of the frost-free season and the corresponding growing season has been increasing nationally since the s, with the largest increases occurring in the western United States, affecting ecosystems and agriculture.
Across the United States, the growing season is projected to continue to lengthen. In a future in which heat-trapping gas emissions continue to grow, increases of a month or more in the lengths of the frost-free and growing seasons are projected across most of the U.
The largest increases in the frost-free season more than eight weeks are projected for the western U. The increases will be considerably smaller if heat-trapping gas emissions are reduced. This NASA visualization presents observational evidence that the growing season climatological spring is occurring earlier in the Northern Hemisphere. Average U. More winter and spring precipitation is projected for the northern United States, and less for the Southwest, over this century.
Projections of future climate over the U. This trend is projected to occur even in regions where total precipitation is expected to wafming, such as the Southwest.

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? Droughts in the Southwest and heat waves periods of abnormally hot weather lasting days to weeks everywhere are projected effectss become more intense, and cold waves less intense everywhere. 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 U.
By the end of this century, what have been once-inyear extreme heat days one-day events are projected to occur every two warminb three years over most of the nation.
Droughts in the Southwest and Central Plains of the United States in the second half of the 21st century could be drier and longer than anything humans have seen in those regions in the last 1, years, according to a NASA study published in Science Advances on February 12, 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 s.
The relative contributions of human and natural causes to these increases are still uncertain. Hurricane-associated storm intensity and rainfall rates are projected to increase as the climate continues to warm.
This video explains the findings of this study. Global sea level has risen by about 8 inches since reliable record keeping began in It is projected to rise another 1 to 8 feet by This is the result of added water from melting land ice and the expansion of seawater as it warms.
In the next several decades, storm surges and high tides could combine with sea level rise and land subsidence to further increase flooding in many regions. Ocean waters will therefore continue to warm and sea level will continue to rise for many centuries at rates equal to or higher than those of the current century.

“Global warming is a gradual increase in the earth’s temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants. 4 hours ago · Pictures around the Earth from NASA’s website. Nine of the hottest years in human history have occurred in the past decade. PUBLIC DOMAIN. As the consequences of global warming become more dire, a research team led by Stony Brook University Professor Jessica Gurevitch is examining the ecological impacts of using a form of geoengineering to mitigate the effects of global warming. Sep 14, · Leer en espanol The effects of global warming in the Arctic are so severe that the region is shifting to a different climate, one characterized less by ice and snow and more by open water .
The fact that global warming poses a threat to the environment and wildlife has been a public concern for years. Lesser known is the degree of global warming's direct impact on humans around the world. Research has been conducted to explore the effect on biological, ecological, and geological systems, but less research has focused on how humans specifically are affected by global climate change.
The humans most directly affected by these issues are those living in poverty and marginalized communities. Not only are these individuals more likely to experience the negative consequences of global warming, but are also less likely to have the financial resources to deal with these issues.
As a result of these changes, the World Health Organization estimates that at least , lives have been lost since Other experts, like the Global Humanitarian Forum, believe that number is much higher and estimate that over , deaths occur annually as a result of global warming.
This article takes a closer look at the global warming threats facing humans around the world. The health issues that result from ecological systems changes are often secondary effects of events like changes in agricultural production, coastal ecosystem production, and mosquito population size.
The global warming events that directly influence human health include: droughts, air pollution, natural disasters, and heat waves. Indirectly, human health is affected by conflicts over natural resources particularly fresh water , forced resettlement, mental issues after disaster survival, and increasing levels of poverty. As the climate becomes warmer, dengue- and malaria-carrying mosquitos are able to rapidly multiply and infect thousands of unsuspecting victims. Additionally, food is at risk of contamination in warmer climates, resulting in increased diarrheal disease which often kills children, particularly those under 5 years of age.
Crop production is also reduced, leading to increased malnutrition and even starvation in extreme cases. Additionally, increased temperatures often result in increased pollutants in the air, which has been linked to asthma and other respiratory problems. Global warming also allows for faster and wider spread of infectious diseases.
Community location is also at risk as a result of global warming. This is particularly true of coastal regions, which are threatened by continuously rising sea levels. Rising sea levels are particularly detrimental on small islands as people living in these areas have no alternatives for resettlement.
Within coastal communities, the poorest individuals tend to live in the floodplains. When flooding does occur due to increasing natural disasters like hurricanes and tsunamis, the poorest individuals most often lose their homes.
Unfortunately these people are less likely to have home insurance, savings accounts, or access to credit in order to overcome the disasters. Estimates suggest that millions of people will suffer sea level rise flooding by This will disproportionately affect large urban areas.
Climate security is a term used to describe threats and insecurity to a country due to the effects of climate change. These changes often make an already difficult situation worse, which can lead to violence and instability in international relations. As global warming continues to cause sea level rise, unpredictable weather patterns like heavy rains , drought, desertification, and lack of access to water sources, inhabitants of the most affected regions will likely take part in environmental migrations as they search for safer homes.
These large-scale migrations are expected to provoke violent conflict as groups of people begin fighting for access to scarce resources. Researchers have already identified several instances in which global warming and climate change have resulted in conflict.
For example, the Syrian Civil War began after approximately 1. The Somali Civil War has also been connected to extreme heat waves and drought. History shows that this pattern of climate change followed by conflict has been happening since before the preindustrial age. Just as global warming and climate change can negatively influence access to food and water, it also has an impact on access to energy resources.
Thermal power stations, which use fossil fuel derived heat energy to create electricity, require freshwater for cooling. As freshwater becomes more scarce due to drought, the demand becomes more pronounced. Additionally, as temperatures continue to increase, thermal power stations produce electricity less efficiently, which requires burning more fossil fuels to maintain output levels. Oil and natural gas deposits are often found off of coastal areas.
Higher occurrences of hurricanes, flooding, cyclones, and tropical storms threaten the infrastructure used to extract these resources. In the post-Hurricane Katrina Gulf of Mexico, oil and gas stations were destroyed and another were damaged. This disruption in extraction often results in increased prices for consumers, which again has a more detrimental impact on those individuals living in poverty. The same natural disasters that threaten the oil and gas industry also work against nuclear energy.
Because salt water causes corrosion to processing plants, freshwater must be utilized. When freshwater is unavailable, explosions, nuclear meltdowns, and leaked radioactive materials are all likely to occur. This was seen in the Fukushima Daiichi nuclear disaster in Japan after the earthquake and tsunami of Increased temperatures have also forced other nuclear power plants to shut down over safety concerns, as in France in , , and Even renewable energy sources such as hydroelectricity are not safe from the effects of global warming.
Hydroelectricity relies on a large amount of freshwater to run over dams in order to move turbines and produce energy. Decreases in water availability mean decreases in energy production at these sites as well. The evidence is clear and should not be ignored.
Global climate change and warming threaten the lives of plants, animals, and people. If governments and industries do not come together soon to reverse these effects, it may be too late. The impact of climate change on the lives of humans could be disastrous if more isn't done to prevent it.
