Question: How are the major rivers of india affected by climate change?
I have some homework, i need to make a chart about how the major rivers of india are affected by climate change. it would be really really helpful if you can give me a link to a site or any information on the topic. thanx!!
thanx soooo much for the answers!! u guys rock!!

Answer:

Answer by Tom A
Many rivers in India are fed by melt water from glaciers. Many of these glaciers are rapidly disappearing due to climate change. When the glaciers are gone, so is a reliable source of water from the rivers.

Question: Climate change is an environmental issue in the news almost daily. Air pollution impacts us on a global level.?
Climate change is an environmental issue in the news almost daily. Air pollution impacts us on a global level. What are the implications of global warming? And, do you feel the efforts to improve air quality are worth the economic costs?

Answer:

Answer by A Modest Proposal
I am very strongly inclined to think that this is a prompt for an essay for school. The wording is very similar to ones I have seen. I have to wonder why you would decide to lead into the post with a statement, and not a summarizing question that would lead in to further details (as most people anywhere on this site, even outside of the Global Warming section, do), if your intent was really to ask this and not get answers for homework.

I think you should do your own work. However, to answer your question vaguely so I don’t get reported:

>>>What are the implications of global warming?

Rising sea levels, acidification of oceans, alteration of weather patterns around the globe.

>>>And, do you feel the efforts to improve air quality are worth the economic costs?

Yes.

Question: Who else seems to think that Congress used the MJ death to sneak in the Climate Change bill?
I personally think that Congress used the media attention on MJ’s death to sneak in the Climate bill without it gaining attention from the masses. It sounds like something they would do. Anyone else agree, disagree?
Pelosi is probably the one person in this country who is the most out of touch with society.

Question: Since everyone here knows for a fact only humans can change the climate how did the cavemen mange to do it?
I mean it was very cold during the last ice age yet the planet’s climate changed to make the earth warmer. Since everyone here knows for a fact only humans can change the climate how did the cavemen mange to do it?

Question: How Are Penguins Affected By Climate Change in the NORTHERN Hemisphere?
What are some facts or statistics showing that penguins are being affected by climate change in the northern hemisphere NOT southern.

and also what are they being affected by and how do these factors change the penguins life in a negative way ( being related to climate change or global warming) Thanks!

Answer:

Answer by NW Jack
Wild Penguins do not exist in the Northern Hemisphere.

http://en.wikipedia.org/wiki/Penguin#Distribution_and_habitat

The closest thing was the great awk. It went extinct nearly 16 decades ago. http://en.wikipedia.org/wiki/Great_Auk

Edit:
Most of the Global warming that has happened in the last 3 decades has happened in the Arctic (0.5 kelvins), while the Antarctic has not changed much at all. http://www.ssmi.com/msu/msu_data_description.html#figures
During the 3 decades from 1940 to 1970, when the earth was cooling, most of the cooling happened in the Arctic (-0.5 kelvins), while the Antarctic did not change much at all. http://en.wikipedia.org/wiki/File:Global_Cooling_Map.png

So perhaps, you were asking because most of the changes have been in the Arctic. Note that the cooling map linked to above looks like a negative of the warming map linked to above.

Edit @Antarcticice:
The increase of 0.5 Kelvins for the Arctic, and the lack of change in the Antarctic is based on the TLT (Temperature Lower Troposphere) map in the SSMI.com (satellite measurements) link that covers the last 31 years. The decrease of the same amounts between 1940 and 1970 is based on the Wikipedia link right next to the numbers.

Yes, Arctic warming and cooling at twice the global average is about right as per the same links.

If you wish to know whether or not the ice cover in the Arctic is “normal”, you need to consider the 95% confidence level, normally considered the minimum for statistical significance. (Expect a result outside of 95% confidence once in twenty samples if everything remains normal.) This is at 2.1 standard deviations from the curve for a 22 sample data set. Here is a link to your graph with the the 94% confidence level (2 standard deviations) added. http://nsidc.org/data/seaice_index/images/daily_images/N_stddev_timeseries.png
Notice that the current ice cover is not an outlier. http://en.wikipedia.org/wiki/Outlier

As for where the penguins actually live, ice cover is also normal, but slightly above average. http://nsidc.org/data/seaice_index/images/daily_images/S_stddev_timeseries.png

Interesting article you provided about the Antarctic warming. They used 1957 as a base reference point based on the establishment of one of the weather stations there in that year. Note that they did not say how much it warmed, and that they used the same data for the last 31 years that was used to create the map that shows almost no net change for the last 31 years. Their data includes the period from 1957 to 1979 based on a hand full of temperature recording stations that the TLT map I linked to does not. The cooling map that shows no net cooling in Antarctica from ~1940 to ~1970 is based on averages around the start/stop dates based on existing temperature recordings from existing stations there.

You can show either a warming trend or a cooling trend for Antarctica if you cherry pick your dates.

Question: Why did climate change happen during other time periods?
Because climate change happen one way in the past, does that mean it must happen the same way again?

Answer:

Answer by John Terry
“Why” is not fully understood. We do know that CO2 levels were lower during many of those periods than they are today. That does mean that whatever caused those comparable periods COULD have caused the early and late 20th century warming periods.

Climate change happened in the past without an increase in CO2 and for reasons not fully understood – apparently we agree on that point. Does it mean that the 20th century warming necessarily WASN’T caused by CO2?

No.

It DOES mean that we cannot simply INFER that it was caused by CO2.

And that inference is the entire case for man-made global warming.

…..that inference plus long-range predictions made by models that haven’t accurately predicted shorter-term temperature shifts – which means it’s dishonest or ignorant to insist that the models accurately reflect – and thus can rule out – all natural climate variables.

It’s simply not accurate to conclude that “natural forcings cannot explain the late 20th century warming” – it’s accurate to conclude that “our understanding of how natural forcings is limited and we cannot prove a natural cause or causes for the late 20th century warming – but we cannot prove what caused prior, comparable warming or cooling periods either.”

Question: Are we all doing our part to tackle climate change?
Admit it, some of you guys are not encouraging climate change as you should be. So, give me some ideas about what you are doing to tackle it in order to save our planet for future generations to come.

Answer by Raptor
My company and I are doing a whole lot to reduce our carbon footprint, and I am President of the Company. My AC is kept at a higher temperature, but made just as comfortable by running fans using the principal of a wind chill. I don’t use any plastic bottles for beverages. I drive a Chevy Aveo, which has lower emissions and gets excellent gas mileage. And when I can get my hands on them, I’m going to roll solar foil on the roof, generate more electricity than I make, and get paid for the power I send back. But most importantly, I’m creating a proposal for energy independence by 2020 and am building support so that I can make a genuine impact.

Question: The judge and jury have spoken regarding climate change: why is the gallery still seating in their seats?
In the real world, questions have been asked and answered and many countries are making good preliminary progress in acknowledging the problems that exist and will unfold due to human influenced climate change. Why are so many members of the gallery in Yahoo Q&A glued to their seats and protesting the verdict?
