discuss current and future trends of climate change.
Answers
Answer:
In recent years, there has been complaints of rising sea levels, increase in temperatures, acid rain and increases in amounts of gases in the atmosphere around the global.
Explanation:
auses of Greenhouse Effect:
Deforestation or the clearing of forest trees. Forest trees are responsible for absorbing a high percentage of the Earth’s carbon dioxide gas and when these trees are cleared and not replanted, the levels of gas increases globally.
Burning of fossil fuels and vehicle emissions are also adding to high levels of carbon dioxide within the atmosphere.
Releasing the use of Chlorofluorocarbons into the atmosphere from aerosol sprays.
Release of industrial emissions.
How can we reduce its effect on the Earth?
Forest reserves is an important natural resource and should be kept protected by strict laws.
Reforestation should be practiced wherever clearing has occurred.
Use of alternative sources of energy such as solar, wind and tidal energy that does not contribute to pollution.
Car pool is a practice that should be encouraged as well as walking and cycling.
Use of CFC free sprays wherever necessary
Little to no industrial emissions (filter gases and toxic substances exiting the factories at all times.
Do not burn garbage or other waste materials since this adds to the increased levels of carbon dioxide in the atmosphere.
What is Global Warming?
This is a continuous rise in the average temperature of the Earth’s climate system. Since 1971, 90% of the warming has occurred in the oceans. Despite the oceans dominant role in energy storage, the term "global warming" is also used to refer to increases in average temperature of the air and sea at the Earth's surface. Since the early 20th century, the global air and sea surface temperature has increased about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980. Each of the last three decades has been successively warmer at the Earth’s surface than any preceding decade since 1850.
Causes of Global Warming
Increased concentrations of greenhouse gases produced by human activities is the main contributor of Global warming. According to the International Panel on Climate Change (IPCC) 2013, explains that the largest driver of global warming is carbon dioxide emissions from fossil fuel combustion, cement production and land use changes such as deforestation.
Burning fossil fuels release large amounts
of gases into the atmosphere.
Slash and burn agriculture practices contributes to removal of natural vegetation from the land as well as it adds to the amount of carbon dioxide gases in the atmosphere.
What are some of the effects of Global warming?
Human influence has been detected in warming of the atmosphere and the ocean.
Changes in the global water cycle.
Reductions in snow and ice (less glacier formations).
Global mean sea level rise.
Extreme climate changes - more frequent extreme weather events including heat waves, droughts and heavy rainfall.
Ocean acidification (caused when carbon dioxide dissolves into the ocean to form carbonic acid and this lowers the pH of the water making it more acidic resulting in coral bleaching, calcified plankton and threatens food chains) and species extinctions due to shifting temperature regimes.
Effects significant to humans include the threat to food security from decreasing crop yields and the loss of habitat from inundation.

What can be done to decrease the effect of global warming?
Answer:
Future changes are expected to include a warmer atmosphere, a warmer and more acidic ocean, higher sea levels, and larger changes in precipitation patterns. The extent of future climate change depends on what we do now to reduce greenhouse gas emissions. The more we emit, the larger future changes will be.
