    1.)The temperature of global warming has increased because of the oil petrol and gasses such as toxic and green house gases.
    2.)Some negative things are that animals are not surviving because of the heat that’s touching them that’s why they are losing their life.

    1.)The process of global warming is that pollution is been coming from factories and much more then it sinks into the clouds which damages many things.
    2.)It effects many species that are attached to the heat which will kill them and it might of have a chance to do it with us humans also it will cause the shops to close down and places will just be like landfills.

    1.)Global warming has being increased over the last 100 years because tech has improved.
    2.)It is effecting our environment such as crops not having any rain to absorb then be finished and millions of species and much more.
    3.)It is possible and not e.g it is possible because if you live close or near somewhere you can walk it there but it is impossible if you live far away somewhere you will need to take a vehicle.

  2. Global warming is a gradual rise in the average temperature of the earth’s climate system. Global warming is the result of emissions of greenhouse gases and changes in solar irradiance. Furthermore , the temperature of the earth has increased because people have used lots of greenhouse gases such as carbon dioxide and toxic waste. The greenhouse gases pollute the air and makes the atmosphere thicker which will stop the sun rays from escaping. Lots of animals habitats are being destroyed such as polar bears ,seal and penguins because the high temperature will melt the ice and the water levels will increase . Global
    warming may cause the death of people because they may not be adapted to the high temperature. Particualry,in the past 100 years global warming has increased because more people are using petrol for cars and houses and toxic sprays (toxic waste).Also there are more factories and industries which create pollution and deforestation, the destruction of forest to make lands for human uses. Global warming can be reduced by changing our life style and stopping some bad habits such as the excessive use of cars and gases.

  3. Global warming is a term used to describe an increase on the worlds natural temperature of the earths oceans and atmosphere , a change so serious some believe it may permanently affect the worlds climate .Climate scientists who have been studying the earths temperature have noticed a huge increase . While some view global warming as it has had a substantial impact on the earths climate change , some people dont . The actual increase global warming has had is from around four degrees celcius and eight degrees celcius

  4. Silver:
    The processes of global warming is when the temperature rises .If global warming continues the poles will start to melt and causes the sea level to go higher and floods island such as England and much more.The effect of global warming to our planet are pollution,toxic gasses and cvc gasses. Pollution can come from factory and industries.

    Global warming has carried on for 100 years because more people need appliances for having a normal life other wise more people are getting poor by losing there homes food and eveything they have. The impact that global warming have on our planet is or is making to

  7. The world is getting warmer. Whether the cause is human activity or natural variability—and the preponderance of evidence says it’s humans—thermometer readings all around the world have risen steadily since the beginning of the Industrial Revolution. (Click on bullets above to step through the decades.

  8. Increasing levels of carbon dioxide and other gases like methane causes greenhouse effect,where sun’s energy is trapped causing earth and particularly oceans to warm.In the past 100 years human activities began to increase resulting in greenhouse gases escaping into the atmosphere. The rising level of CO2 is caused mainly by burning of fossil fuels, manufacturing of cement, chemicals and metals and deforestation.
    Impact of Global Warming:
    1.Crops could fail or be damaged by temperature change and extreme weather changes.
    2.Sea level will keep rising as the polar ice sheets and glaciers melt.
    3.Coastal cities are vulnerable with increased risk of flooding.
    4.In summer more heat waves are likely.
    How we can reduce Global Warming:
    1. Reducing waste by choosing reusable products, recycling paper, aluminium cans and glass will reduce CO2 emission.
    2. Wherever possible use public transport and bicycle instead of car.
    3. Switch off the lights if not in use.
    4. Finally but most important, tree plantation will reduce CO2 from atmosphere as trees absorb CO2 from atmosphere and release oxygen.

  9. Global warming and climate change refer to an increase in average global temperatures. Natural events and human activities are believed to be contributing to an increase in average global temperatures. This is caused primarily by increases in “greenhouse” gases such as Carbon Dioxide.

  10. Global warming is very dangerous because when the levels increase many stuff get damage .Global warming is caused by technology and it is even caused by the gas. 100 years ago, gas could of escape however now gas can not escape because now the clouds get thicker.

  11. The temperature of the earth has increased because of global warming.Global warming is when the atmosphere gets more thicker and thicker after that the sun gets blocked so it gets hotter and hotter everyday and night.Because of CFC and POLLUTION it can go to the atmosphere and block it.SAVE OUR PLANET!!!!

  12. There is clear evidence that global warming has increased more rapidly in the past few years. Scientific reasons for increased global warming are increased levels of carbon monoxide due to industrial revolution. There is increase in greenhouse gases are almost due to human activity. The increase is due to deforestation, burning of fuels, pollution and manufacturing of chemicals and metals.

    Because of global warming ice is melting and this is resulting in rising sea levels.(2)Hurricane and other storm are likely to become stronger.(3)Floods and droughts will become more common.(4)Some diseases will spread such as malaria carried by mosquitoes (5)Less fresh water will be available.

    We can reduce global warming (1) by using reusable products instead of disposable ones and by recycling paper, plastic, glass and aluminium cans,(2) by buying energy efficient products that consumes less electricity, (3)choosing to bike or walk instead to go in car for short distance (4)turning down light when we are asleep and away from home (5)most importantly by planting trees

  13. The temperature has increased because of global warming. Polar bears ice caps will melt ,therefore sea levels will rise and the temperature will rise and change the landscapes in the Arctic circle it’ll endanger several species of animals. Economic consequences most of the effects of anthropogenic global warming won’t be good.
    Hurricanes do cause lots of money in damage and diseases because it’s lots of money to treat animals.

    Therefore anthropogenic means chiefly of environmental pollution.

  14. A few years ago, gases caused by factories passed through the earth’s atmosphere easily, but now we have more factories more gas needs to escape the atmosphere, but instead of passing through the atmosphere, the gases make the atmosphere thicker meaning it can’t escape so it has no choice but to come back down to earth, and just like the gases, the sun’s rays can’t escape the atmosphere once they are in it, so instead the sun’s rays leaving, they stay in the atmosphere causing global warming. Global warming effects our planet by melting ice in the arctic, making more sea,flooding many coastal villages and killing sea life by washing them up on the shore.

  15. The global warming is dangerous because when the gas go the clouds is getting thicker and the sun will be stuck in the earth and the earth people will be floated in the malten ice

  16. The global warming is dangerous because when the gas go the clouds it getting thicker anbs the sun will be stuck in the earth and the north pole will be floated of the ice melted

  17. Gold
    Global warming has increased rapidly in the last few years because when the sun rays in our city it can’t go back out again because the clouds are getting more thicker.Some cold countries will become hotter and the ice will melt and the North Pole has animals such as polar bears so they will lose their habitats if the ice melts and the water will rise.It is not possible for us to reduce global warming without comprising our lifestyle .

    Global warming is affecting our planet Because green house gases such as carbon dioxide is growing into our atmosphere and it is affecting our crops because of less rainfall.

  18. The average temperature of the Earth is increasing because of global warming,due to the increasing of greenhouse gases,such as,carbon dioxide and toxic gases,which go into the Earth’s atmosphere.The negative impacts on global warming is that land is being wasted,animals are being extincted and are humans are being dead.Global warming is having an effect on crops because of less rainfalls.Due to the heat that goes into the atmosphere,cold countries are getting very hot,meaning the ice is being melted,so the world is being flooded and animals,for example,polar bears can’t survive in these conditions.The process of global warming is that first pollution is being created from deforestation,factories and cars.Next,the pollution goes into the clouds,which makes it get damaged.After,the sun shines down,then it wants to get out but it can’t get out because clouds have been damaged,this causes global warming.Over the past 100 years global warming has increased because technology has improved.The impact on global warming on our environment,is that people are being sick,shops would be closed down and road would look like
    wastelands.

  19. Global warming has increased by the past 100 years by the use of:cars,factories,trucks and,also the most used is your technology at home.The change of climate has put animals in serious need of more ice such as polar bears,they have suffered from the lack of ice polar bears are suffering greatly.The Global warming has rapidly increased because of the use of your technology at home.

    Global warming has been impacting us by using sun rays and also creating toxic waste,oxygen’s population is decreasing and the nitrogen oxide and carbon,dioxide levels are rising.

    Yes it is possible we could stop using cars instead bikes,roller skates,skateboards and scooters.All of this is damaging our planet.SAVE OUR PLANET!!!!!!

  20. When smoke and gas reaches the sky, it goes through the earths atomphere however,if to much enters it won’t go through it will come back down and damages the cloud! Global warming is destroying our crops in addition, global warming is killing animals and there habitats. Animals in the pole can survive in this condition and they are at risk.
