A lack of rain or snow for an extended period causes dry weather, otherwise known as a drought (**). When temperatures rise because of the global climate change, moisture from the land and water evaporates, which leaves less water on the Earth (**). While some places are getting more snow and rain to make up for the climate change, others are getting less.
Droughts are becoming longer and more intense internationally since the 1970’s (**). If there is no change, studies show that droughts are going to keep getting longer and more severe. Droughts are dangerous because they mean less water for things like watering crops, drinking, and production electricity by hydroelectric dams. The Southwest United States is currently at risk for droughts because water supplies are draining in states like Arizona, where water is insufficient enough as it is.
Wild Weather
Warm ocean water serves as the energy to power hurricanes and other tropical storms. The storms and hurricanes get fiercer with faster winds and denser rain when the upper layer of the ocean gets warm. Climate change causes storms to be more extreme because of the higher heat and added evaporation. Storms in the Atlantic have become even stronger over the past twenty years. The United States has also experienced more powerful one-day storms since the 1980’s that generate rain and snow at an unusual rate (**). With the weather getting warmer, it is expected that heavier snowstorms and rainstorms will happen more often, and that storms around the globe will keep getting stronger. Storms and hurricanes are hazards that can damage buildings, hurt crops, cause floods, and put people’s lives in danger.

In the Great Plains, rising temperatures, quick evaporation, and the occurrence of drought cause water to be even scarcer. The reduced water supplies and hotter temperatures are threatening things affiliated with agriculture, like ranching and the natural lands. The climate change is also affecting plants and animals by shifting major habitats, such as the prairie dog’s potholes.
In the Coastal region, sea levels continue to drastically rise, increasing the risk of people living in coastal cities. Because of the temperature rise and warmer waters, there is a seasonal decline of oxygen in the coastal ecosystems that will continue to increase. High temperatures and high acidification of the ocean will affect coral reefs. And, fluctuating ocean currents will affect coastal ecosystems and ways of life.
For example, then, drought is difficult to define in modern standards, it is typically classified as a shortage of water, usually associated with a deficit of rainfall. That is, drought occurs when the demand or use for water exceeds the current supply of water. It follows, then, the Colorado river drought does not solely affect one area, it’s grandeur has affected the whole southwestern United States. Additionally, the Colorado River Basin Water Management: Evaluating and Adjusting to Hydroclimatic provides information on the meager volume of rain fall. In theory, then, combined with increased temperatures from global warming, and a deficient of rainfall both circumstances have had a descending effect on most surrounding
While it is hard to directly connect Hurricane Sandy to global warming, it is clear that warmer waters and increased sea level contributed to the severity of the storm. Higher sea levels increase the chance that hurricane winds will bring more water on land and storm surges that reach further inland. The Atlantic region is already experiencing sea level rise, and globally this trend is expected to continue. Ocean temperatures are also on the rise, an...
For more than five years the state of California has been in a drought, and now all the people of California want is a break from all the rain. The state is being put under water from top to bottom. More than 200,000 people have left their homes in parts of north California, in fear of the dams breaking. With this amount of rain the question on many people’s mind “Is California’s epic, record-setting drought, five years long, finally over?” Some are saying yes while the other are sure it is not. The top part of the state is out of the wood from drought, while the middle and southern part is still very much in a drought. The last time the state had what is considered an abnormal amount of rain/snow was in 82/83. This year’s amount is almost
The coral reefs of the world are of vast importance because they host 25% of all marine life on the planet. Now that corals have been briefly described, we can see why the effects of climate change damage coral reef systems. Ocean acidification is a result of climate change. Acidification is caused by an increase in carbon dioxide in our oceans and leads to a decrease in the pH levels of seawater. This pH decrease reduces the ability of corals to make their hard skeletons.
Hurricanes are enormous heat engines that generate energy on a staggering scale. They draw heat from warm, moist ocean air and release it through condensation of water vapor in thunderstorms. The current hurricane that occurred was Big Sandy. FEMA became involved with the issue when the hurricane hit Rockaway, New York. President Obama declared a major disaster on October 30, 2012.
There are different beliefs as to the probable causes of the California drought. The two primary theories are that the drought was either caused by climate change or climate variability. Alan Stahler, a columnist, followed a group of scientists who discovered the true cause of the drought, “The recent multi-year drought was caused not by global warming, but by the sea surface temperature pattern – itself caused by natural variability” (Stahler par. 14).Regardless of the cause of drought, the drought itself has many negative effects on the people of California. Many individuals will suffer due to the drought, but one of the most affected will be farmers. Katharine Mieszkowski, a senior reporter for Reveal, reports the effects of the drought
One resource that thoroughly explains the effects of a drought are websites and these couple of websites were very thorough in their explanation of the causes and effects of droughts.
Due to geography and population growth, the Middle East nations are faced with a growing demand for a shrinking water supply. Throughout most of the Middle East region rainfall is irregular and the rainy season is very short. The World Bank reports that this area (including North Africa) has 5% of the world’s population, but only 1% of the world’s water. Droughts have been occurring more frequently and lasting longer, warning of a bleaker future.
My first article, “Study Finds Pattern of Severe Droughts in Africa” which I retrieved from The New York Times, written by Andrew C. Revkin on April 17, 2009, has the main point that Sub- Saharan Africa is home to tens of millions of the world’s poorest people as said by climate researchers. Most of Africa’s 390 million people live off of less then a $1.25 a day. These people’s lives depend on the quality of the land and rainfall. Kevin Watkins, director of Human Development Reports of the United Nations, says, “Even small climate blips such as a delay in rains, a modest shortening of the drought cycle, can have catastrophic effects”. Timothy M. Shanahan of the University of Texas and Jonathan T. Overpeck of the University of Arizona have warned that global warming that is caused by human exposure of greenhouse gases is a major reason for droughts in Africa. Major droughts have also been linked to pattern increases and reductions in surface temperatures of the Atlantic Ocean. In 1972 to about 1974, Ethiopia’s human population was about 31 million; from 31 million, one million died due to t...
A drought is a very long and abnormal duration of time where there is a place with less very low rainfall, which makes the place, have no enough water for their users. Natural disasters are bound to happen around the world at anytime. Tsunamis, Storms, Earthquakes, droughts, etc. some of them are bound to happen due to the locations of the place and their weather conditions. Droughts are common in subtropical areas of the world and are faced by countries such as USA and Nigeria. Due to climate change, USA and Nigeria there has been a rise of temperature by nearly 1C since the beginning of the 20th century.
They say that warmer waters will increase the power of tropical storms such as hurricanes and typhoons. Again the statistics given are made by a select group of notoriously bias paid scientists. Meaning the waters won’t get warmer. The waters get warmer every year because of the natural warming and cooling of the earth’s environment. This is the way that the earth works because of the shape and rotation of the earth around the sun. Added on to that is the fact that the storms that have been forming nowadays have been the same size as always just in new locations. This is just one e...
Climate change is one of the major issues surfacing earth over the past century. The earth’s temperature has increased over the years leading to detrimental effects on the economic and life sources of people, especially that of agricultural production and livestock. The Merriam-Webster online dictionary (2014), defined climate change as a change in global climate patterns apparent from the mid late 20th century. The Intergovernmental Panel on Climate Change, IPCC, (2007) predicts that by 2100 the increase in global average surface temperature may be between 1.8° C and 4.0° C. With increases of 1.5° C to 2.5° C, approximately 20 to 30 percent of plant and animal species are expected to be at risk of extinction. Moreover, the IPCC (2007) purported that climate change has severe consequences for food security in developing countries. There are numerous factors that are solely responsible for this change which are both natural and man-made. Climate change has led to a decrease in quality and quantity of plant produce and livestock because of heat stress, drought and an increase in plant and animal diseases.
Climate change is currently affecting agriculture because it is causing prolonged droughts, violent flooding, sea level to rise, and also health related issues. Droughts and flooding utterly affect agriculture because it damages cultivation since the amount of water applied to crops and farming is fundamental to the...
One of the major effects of global warming is the rise of sea level due to thermal expansion of the ocean, in addition to the melting of land ice. Now there are dozens of land areas that sit well below sea level and the majority of those land areas are very well populated. At least 40 percent of the world 's population lives within 62 miles of the ocean, putting millions of lives and billions of dollars ' worth of property and infrastructure at risk. (Juliet Christian-Smith, 2011) This means if the sea level rises to the projected level of 25 meters (82 feet) half of the world will retreat back to the ocean. (Rohrer, 2007) Also rising sea levels means higher tides and storm surges riding on ever-higher seas which are more dangerous to people and coastal inf...
