Global Warming

Global Warming is the century-scale rise in the average temperature of the Earth's surface, oceans, and atmosphere due to an increase in the greenhouse effect. Greenhouse gases such as carbon dioxide from burning fossil fuels or from deforestation trap heat that would otherwise escape from Earth. This warming is causing climate patterns to change.

When heat from the sun causes water to change to a gas or water vapor condensation when water vapor cools and changes into water?

Water change to gas state or water vapour when a heat break bands between molecules, these molecules now are free, but they flow under special pressure(low) when molecules have an accident with any cool surface the instanteneous break in bands return to be more strong to convert vapour to a liquid water again, the pressure now is higher (pressure of water>pressure of air)...

How do carbon sinks reduce greenhouse gases?

A carbon sink is a storage for carbon. A tree is a carbon sink because it absorbs carbon dioxide (a greenhouse gas) from the atmosphere, stores the carbon and releases the oxygen. So forests are major carbon sinks which reduce the levels of greenhouse gas in the atmosphere.

Does greenhouse and global warming have anything to do with hurricanes and typhoons?

Hurricanes and typhoons are weather. Climate is a longer term look at how weather averages out over the years. So one severe tornado is not evidence of climate change and global warming. But if the numbers and the severity of weather events change over time, then that may be a part of climate change caused by global warming.

How are non renewable energy sources better than renewable resources?

Because renewable sources can be replenished

(apex)

because we will not run out of them

How food security threatened by climate change explain with diagram?

Climate change can impact food security in multiple ways, such as through extreme weather events, changes in temperature and precipitation patterns, and impacts on crop yields. These factors can disrupt food production, increase food prices, and affect crop quality, ultimately leading to food scarcity and malnutrition. Here is a simplified diagram illustrating this relationship:

Climate Change --> Extreme Weather Events, Temperature/Precipitation Changes --> Crop Yield Reduction, Food Price Increases, Food Scarcity, Malnutrition.

What are the effects of man made fire on the environment?

There are two types of fires

1 man made fires

2 natural fires

as natural fires cause many smoke but are caused rarely such as forest fires they are less harmfull to the environment but man made fires had made can many harms to environment . They also produce many smoke and are use most wich is harmfull to ozon layar. It is the best example of global warming. they are good for humanbeings but not for nature.

What are three ways humans affect earth's system?

Three big ones are:

  • Global climate change
  • Plastic, chemical, sewage and other pollution in oceans and fresh water
  • Depletion of fish stocks and forests by unsustainable use

How does deforestation increase greenhouse gases?

Basically, tree's body is a storage of Carbone "C"... when forest grows, it takes Carbone from the CO2 and release O2.

So it produce O2 and decrease CO2 WHEN IT GROWS.

if you cut a tree to make furnitures, you dont release any C in the atmosphere, but you reduce the forest's size that then can grow again.

Small trees grow faster than large ones therefore they consume more carbone.

As a result, by doing deforestation and using the wood, you decrease CO2 concentration.

What causes the coriolios effect?

The Coriolis effect is caused by the rotation of the Earth. As the Earth rotates, objects traveling on its surface appear to be deflected due to the difference in speed of rotation at different latitudes. This effect is strongest at the poles and decreases towards the equator.

How will animals be affected by ozone layer depletion?

Ozone layer depletion can increase the amount of harmful ultraviolet (UV) radiation reaching the Earth's surface. This can lead to various health issues for animals, including skin cancer, cataracts, and immune system suppression. Additionally, it can affect the food chain by damaging phytoplankton and disrupting ecosystems.

How are plants affected by ozone layer depletions?

Ozone layer depletion leads to an increase in ultraviolet (UV) radiation reaching the Earth's surface. This excessive UV radiation can harm plants by damaging their cellular processes, reducing photosynthesis rates, and increasing the risk of mutations in their DNA. Overall, ozone layer depletion can hinder the growth and development of plants and disrupt ecosystems.

Does warm air have more density tan cold air?

No, warm air is less dense than cold air. As air warms up, its molecules move faster and spread out, leading to a decrease in air density. Cold air, on the other hand, has slower-moving molecules that are closer together, making it denser.

Is it true people are major polluters of earths fresh water supply?

Yes, human activities such as industrial waste, agriculture runoff, and improper disposal of pollutants can significantly contribute to the pollution of Earth's fresh water supply. This pollution can impact ecosystems, human health, and water quality. Implementing sustainable practices and regulations can help mitigate this problem.

What can you do to reduce the human impact on climate change please give three practical strategies?

  1. Reduce energy consumption by using energy-efficient appliances, LED lighting, and insulating your home.
  2. Shift to renewable energy sources like solar, wind, or hydroelectric power.
  3. Cut down on meat consumption and choose plant-based diet options to reduce greenhouse gas emissions associated with livestock farming.

Can Global warming lead to flooding in coastal areas?

Yes, global warming can lead to flooding in coastal areas due to melting ice caps and glaciers raising sea levels, as well as increasing the severity of storms that can cause storm surges. This can result in higher tides and more frequent and severe coastal flooding events.

What is one of the worst causes of global warming?

One of the worst causes of global warming is the burning of fossil fuels, such as coal, oil, and gas, which release greenhouse gases like carbon dioxide into the atmosphere. These gases trap heat and contribute to the warming of the planet.

Is pollution a major cause for global warming?

Pollution, specifically greenhouse gas emissions, is a significant contributor to global warming. Human activities like burning fossil fuels release these gases into the atmosphere, trapping heat and causing the Earth's temperature to rise. Efforts to reduce pollution can help mitigate the impacts of global warming.

Is tornado caused by climate change?

Tornadoes are a result of specific weather conditions such as warm, moist air meeting cooler, drier air. While there is ongoing research on the relationship between climate change and tornado frequency/intensity, it is currently unclear if climate change directly causes tornadoes. Climate change may influence the conditions that can lead to tornado formation, but the direct link is not yet definitive.

How does the increasing carbon dioxide level in the atmosphere influence the amount of energy leaving earth's atmosphere but not the quantity coming from the sun?

Radiation from the sun comes to earth in the form of ultraviolet waves. The more harmful ones are blocked by the ozone layer and the useful ones come through the atmosphere unhindered and warm the earth. This warmth then rises in the form of infrared rays. Infrared heat is trapped by greenhouse gases, so not as much heat leaves the earth as enters it.

What is the environmental impact of energy?

I would think the lost of or Troposphere it is the lower most portion of the Earth's Atmosphere and the one in which most weather and the greenhouse effect occurs may be one of the reason why our sun flairs has been getting throw the ozone ?

What has happened to global temperatures as atmospheric levels of carbon dioxide have increased?

Global temperatures have increased as atmospheric levels of carbon dioxide have risen, due to the greenhouse effect trapping heat in the atmosphere. This phenomenon is known as global warming, leading to climate change and resulting in more frequent and severe weather events.

What percentage of china's population own a car?

As of 2021, around 25% of China's population owns a car. This percentage has been steadily increasing over the years with the country's growing economy and middle-class population.

What three factors contribute to global warming?

1) Continued burning of fossil fuels releasing the greenhouse gas carbon dioxide.

2) Improper disposal of waste, release the greenhouse gas methane.

3) Deforestation, where vast forests were destroyed. All those trees no longer remove carbon dioxide from the atmosphere.
