Answer:
1- One of the most immediate and obvious effects of worldwide warming is the increase in temperatures around the world. The average worldwide temperature has increased by about 1.4 degrees Fahrenheit (0.8 degrees Celsius) over the past 100 years, according to the National Ocean-related and (related to the air outside) Management (NOAA).
The (related to the air outside) carbon dioxide concentration has risen from about 270 parts per million (ppm) before 1700 to about 355 ppm today. Climate changes, including a mean worldwide surface temperature rise of between 2.8 and 5.2°C, have been (described a possible future event) by five independent general circulation models (GCMs) for a doubling of the carbon dioxide concentration. The goals of this paper are to examine plant responses to rising carbon dioxide levels and (related to the Earth's weather) changes and to understand/explain the results of these changes on crop water use and water supplies for the United States.
2- Human activity has increased the direct warming effect of carbon dioxide in the atmosphere by 50 percent above pre-industrial levels during the past 25 years, according to NOAA's 10th Once-a-year (glass building where plants are grown) Gas Index.
I hope this helped you! Make sure you put this in your own words, and if you want me to put it in your own words for you, let me know! Also, you do not have to write all of that, just write the most important stuff! : )
True
Air mass is a volume of air with similar temperatures and humidity. It forms above its source region after days or weeks picking up its particular temperature and humidity. When it is blown over to a region with a different characteristic, it becomes a storm.
Ocean currents are driven by wind
Your question is asking about
Human Impact
Introduction to Human Impact
Human impact on the environment carries many negative longterm consequences.
Consumption, altering habitats, and carbon emissions are all human activities destroying the natural world.
Habitat Alteration
Habitat alteration is changing earth's natural compositing by destroying habitats to build upon or fragmenting habitats for roads and access. This is the biggest threat to biodiversity.
Pollution
Pollution is the contamination of Earth's atmosphere and surface (land and bodies of water).
Disposal of human waste results in land pollution, while burning fossil fuels results in air pollution. Land and air pollution affect water contamination.
Deforestation
Deforestation is the removal and destruction of forests.
Clear cutting completely removes all trees in an area for human consumption, such as building materials, paper products, etc.
Human Population Growth
The human population has continued to increase, which means human impact on the environment will increase as well.
Concerns include lack of space, food, and other resources, as well as disease outbreaks.
Acid Rain
Acid rain is caused by burning fossil fuels, which releases acidic gases into the atmosphere. The gases latch on to water molecules and the result is acid (low pH) rain.
Acid rain results in organism death and destruction of infrastructure.
