what are the possible consequences of global warming?

Question

thank you!!!!!!!!!!

Answer 1

Global warming is objectively irrefutable. It is vested interests, such as oil companies, who are spending hundreds of millions of dollars trying to run a campaign to deny global warming, but most independant scientific research demonstrates that it is already happening: "These conclusions have been endorsed by at least 30 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries. The American Association of Petroleum Geologists is the only scientific society doubting the predominant opinion, but a few individual scientists also disagree with parts of it.".

Potential consequences of global warming include rising sea levels, melting ice caps, changes in weather patterns worldwide, climate changes worldwide, and other phenomena: "An increase in global temperatures can in turn cause other changes, including a flooding of coastal cities, an increase in the frequency and intensity of extreme weather events, reduction in agricultural yields due to changes in the amount and pattern of precipitation, increases in the ranges of disease vectors, reduced summer streamflows, further melting of glaciers, and species extinctions."

1 - 4 are all 'possible'. 1 & 2 are likely and are being observed. I'm not sure about 3 - it depends on the level of warming. Generally a bit of warming increases plant growth but if you warm it up so much that most of the planet turns to desert (this almost certainly isn't going to happen!) then tree growth would go down. So it's possible that 3 won't happen. 4 is possible - ocean currents are driven by a combination of heat flow and the Earth spinning. The Arctic is warming faster than the equator, which is reducing the temperature gradient between the pole and equator, which should reduce heat flow in the long term. It's also possible that melting ice will release a load of freshwater and disrupt currents. On the whole this is very unlikely from what I've read. Zach needs some corrections: 1 - The last 20 years are warmer than the rest of the last 200[1] The coldest temperatures found from ice cores are up to 10C cooler than today. This is still an average temperature that's above freezing if that temperature change was the same across the whole planet. 3 - The Earth has a measurable magnetic field, but that doesn't really affect polar molecules like ozone. The magnetic force is F = q(v x B) where q is a charge, v is velocity and B is the magnetic field. x is the 'vector cross product' which determines the direction[2]. A dipole can be split into 2 equal and opposite charges separated by a small distance. When the dipole is moving, v is the same for both charges. (as is B). The q's will be equal and opposite though, which means the force cancels out. 4 - The IPCC studies[3] say that greenhouse gases all cause net warming, as does this realclimate article covering a NASA climate model[4]. CO2 is important because if you put too much in the atmosphere, it doesn't rain out like water does. So it can be around long enough to 'force' warming. CO2 is a bigger contributor than all the other gases that can stay around for that long - this is why it's concentrated on. Not because methane etc are reflective!

Answer 3

This is taken from the website listed below. You should really see the film "An Inconvenient Truth".



Carbon dioxide and other gases warm the surface of the planet naturally by trapping solar heat in the atmosphere. This is a good thing because it keeps our planet habitable. However, by burning fossil fuels such as coal, gas and oil and clearing forests we have dramatically increased the amount of carbon dioxide in the Earth’s atmosphere and temperatures are rising.

The vast majority of scientists agree that global warming is real, it’s already happening and that it is the result of our activities and not a natural occurrence.1 The evidence is overwhelming and undeniable.

We’re already seeing changes. Glaciers are melting, plants and animals are being forced from their habitat, and the number of severe storms and droughts is increasing.

The number of Category 4 and 5 hurricanes has almost doubled in the last 30 years.2
Malaria has spread to higher altitudes in places like the Colombian Andes, 7,000 feet above sea level.3
The flow of ice from glaciers in Greenland has more than doubled over the past decade.4
At least 279 species of plants and animals are already responding to global warming, moving closer to the poles.5

If the warming continues, we can expect catastrophic consequences.

Deaths from global warming will double in just 25 years -- to 300,000 people a year.6
Global sea levels could rise by more than 20 feet with the loss of shelf ice in Greenland and Antarctica, devastating coastal areas worldwide.7
Heat waves will be more frequent and more intense.
Droughts and wildfires will occur more often.
The Arctic Ocean could be ice free in summer by 2050.8
More than a million species worldwide could be driven to extinction by 2050.9

There is no doubt we can solve this problem. In fact, we have a moral obligation to do so. Small changes to your daily routine can add up to big differences in helping to stop global warming. The time to come together to solve this problem is now – TAKE ACTION

Answer 4

Here are some of the main consequences~
climate change
dirty earth

worst cases~
extinction
end of world

Answer 5

Just watch The Day After Tomorrow. Informative and entertaining.

Answer 6

check out that movie about global warming. Ah.. "An Inconvenient Truth"

Answer 7

watch th emovie An Inconivnient Truth its really good if you want to know about global warming and yes your grandchildren will suffer but you might to if it doesnt slow down

Answer 8

the oceans would rise and cover up lots of inhabited land. half of Florida would disappear. people would need special clothes to go outside to their cars or back inside buildings. special sunglasses, too. water would be rationed all the time or they'd have to figure out how to make water pure enough for drinking. it would be like we all lived in Africa.

Answer 9

It's a scam to initiate global taxation.

Answer 10

Probably the main consequence is the massive waste of resources spent fighting something that doesn't exist.
