Climate consists of physical and chemical processes under interaction with solar radiation on the Earth. Solar radiation is the main source of energy on the Earth, forming and maintaining both human and creature life, including plants and animal. The Earth is just one of the planets in the solar system. Therefore, only one part of solar energy comes to the Earth. In term of the total solar energy coming to the Earth, one third will be reflected back out to the universe due to clouds and glaciers, while two third of the energy will be reflected back out to the universe due to clouds and glaciers, while two third of the energy will be absorbed by the Earth, including the atmosphere, hydrosphere, cryosphere and biosphere.

It is called this because of a similar effect produced by the glass panes of a green house. Shorter wavelength solar radiation from the sun passes through the Earth’s atmosphere, and is then absorbed by the surface of the Earth, causing it to warm. Part of the absorbed energy is then reradiated back into the atmosphere as long wave infrared radiation. A fraction of this long wave radiation escapes back into space; but most of the radiation cannot pass through the GHG in the atmosphere. The GHG selectively transmits the infrared waves, trapping some, while allowing others to pass through into space. The GHGs absorb these waves and re-emits them downwards, causing the lower atmosphere to …show more content…
Runoff is projected with high confidence to increase by 10 to 40% by the middle of the century at higher latitudes and in some wet tropical areas, including populous areas in East and South-East Asia, and decrease by 10 to 30% over some arid regions at mid-latitudes and arid and semi-arid tropics, due to decreases in rainfall and higher rates of evapotranspiration. Drought-affected areas are projected to increase in extent, with the potential for adverse impacts on multiple sectors, such as agriculture, water supply, energy production and health. o It is likely that up to 20% of the world • population will live in areas where river flood potential could increase by the 2080s. Increases in the frequency and severity of floods and droughts are projected to adversely affect sustainable development. Increased temperatures will further affect the physical, chemical and biological properties of freshwater lakes and rivers, with predominantly adverse impacts on many individual freshwater species, community composition and water quality. In coastal areas, sea level rise will exacerbate water resource constraints due to increased salinization of groundwater
Greenhouse gases are those that absorb and emit infrared radiation in the atmosphere. The most abundant greenhouse gases in Earth 's atmosphere are: Carbon dioxide, Methane, Nitrous oxide ,Ozone ,Chlorofluorocarbons (CFCs). Human activities also contribute to climate change by the amounts of greenhouse gases, aerosols (small particles). The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas in the atmosphere.
The Southwest Water Crisis Although the current drought is exceptional for its high temperatures and affecting the largest supply of water in Southwestern United States, the Colorado River Basin, by decreasing the water levels. With the lack of water source it is also negatively impacting human health, agriculture, energy, and ecosystems. Water resources are crucial for any sort of living organism, but very scarce due the current drought, which holds complications for the future and alterations people have to construct to maintain water sustainability. Due to the climate change and warmer weather during the summers caused low snowpack in Rocky Mountains.
Changes occurring in the sun itself can affect the climate change on Earth. The intensity of the sunlight reaching the Earth can cause either warming or cooling. The sun flows a natural 11 year cycle of small ups and downs in intensity, but the effect of it on the Earth’s climate is negligible. However, over the past years, the sun’s intensity has been lower than the mid 20th century, and therefore does not explain the recent warming of the Earth. • Also
California needs a lot of water, since it is one of the top agricultural state. As, water accessibility states choices for “crops and irrigation” approaches. Since, most of the water that is utilized by agriculture goes to five main produces like:” alfalfa, cotton, rice, grapes, and irrigated pasture”. Most water is received from the Sacramento River, Colorado River, as the San Joaquin River. However, all these rivers carry a quite a lot of salt and with climate change happening is creating tings worst.
The greenhouse gases in the atmosphere absorb some of this energy, while the rest is emitted back into space, as a naturally occurring cycle that repeats daily which is needed to keep the earth 's surface warm. The green house gases that humans are adding to the atmosphere are like the steroids of the climate system. The problem is that humans are producing far too much greenhouse gases due to increased human activities that demand the use of energy, which has led to emissions and an increase in greenhouse gases. An increase in these greenhouse gases in the atmosphere means more heat is trapped in the atmosphere, and less is emitted into space, which essentially warms up the average temperature of the earth. A small increase in temperature creates major effects to our environment, which is seen in the idea of climate change.
Rivers, specifically, the potomac river is main water systems that I have chosen to report. The potomac river surrounds multiple states including Virginia, Washington D.C. and Maryland is one of the largest rivers in the eastern coast of the United States. A report from the nonprofit advocacy group American Rivers, noted what locals have said for years: “that urban development is funneling tons of polluted rainwater to the river, that chemical fertilizer and manure from farms make matters worse, and that wastewater overflowing from sewers, along with pharmaceuticals flushed down toilets, contribute to dead zones in which marine life dies and might cause fish to switch sexes. Some male fish in the river mysteriously have eggs.”
This shows that flooding is the most influential consequence of climate change because of how it influences
The energy that comes from solar radiation, as well as heat transfer, create energy which in turn creates temperature. Chapter 3- Temperature : All The temperatures around the world occur because of many reasons.
Finally, the sea level rise and flooding is a big problem people-wise. Flooding causes millions in damage that sometimes cannot be reversed. Flooding is encouraged by climate change because of the increase in moisture trapped in the air, and rain happening earlier in the year and falling on still frozen ground. Houses being destroyed by increased water also leave people homeless and cost a lot to fix. Climate change will cause more natural disasters such as flooding, tornadoes and
So What Causes It? Global warming occurs when greenhouse gases, such as carbon dioxide, nitrous oxide, and methane trap heat inside the earth 's atmosphere. Think about what happens when you open your car door after the windows have been rolled up on a hot day.
The Earth normal temperature rose about 0.6° Celsius in the 20th century. There have been legion global warming durations in Earth history. The long effects awaited from the global warming in the 21st century include heat waves, dryness, flooding, sea levels improving, melting of glaciers and polar ice caps, hastiness and temperature irregularity and forest fires. Accordant to the National Resources Defense Council, climate changes will directly influence water supply sustainability profound the United States in future orientate.
Desertification and climate change in drier areas causes severe water shortages and even droughts. Western culture has created an increase in urbanisation, population and industrialisation,
The effects of the climate change are undeniable in the scientific research. The Intergovernmental Panel on Climate Change and other meteorological organizations measures the temperature of the earth on the daily basis and has indicated the potential increase. Furthermore, the dramatic decline in ice and glaciers in the North and South Pole verify the rising temperature and its impact on the sea level. It should be noted that from last decade, the sea level has been increased due to melting of the ice that ocean currently pose a threat (Shrestha, Babel, & Pandey,
Now another natural cause of global warming is the rising of the seas. The biggest reason for sea level rising is that global warming is causing the air to be warmer and that 's causing glaciers and ice-caps to melt. Sea level rise would affect about 11 out of the 15 biggest cities in the world. The reason this is happening because gases are being released into the atmosphere which is causing the temperatures to rise, which causes the seas to rise. Sea level rising means more money that we have to spend for people living on the coastlines because coastal populations are growing and people are crowding into coastal areas and that area could be underwater in a few years if sea levels keep rising how they have been.
Rising sea levels and higher temperature, dangerous rainstorms and droughts are going up commonly. When the temperature increases, the ice will melt at the North Pole. This result leads to the effect that sea levels
