| ^^^ Thanks mate, cheers. I'll have to look into that one. Sounds like a plausable reason for part of the temperature rise at least. |

| To be perfectly fair, we don't have measurements for Pluto for one of its years (273 Earth years, if I'm correct), so yes, you are correct. The links work for me on two different computers, perhaps it's just you. Dunno. Anyway, the gist of the Jupiter article is that Jupiter has warmed up slightly, which has caused Jupiter to lose two of its major perpetual storms that were in its atmosphere. The article about the Sun said that NASA announced that since the 1970s, the amount of solar radiation emitted has increased by 0.05% per decade. It said this interesting tidbit:
"This trend is important because, if sustained over many decades, it could cause significant climate change," said Richard Willson, a researcher affiliated with NASA's Goddard Institute for Space Studies and Columbia University's Earth Institute, New York. He is the lead author of the study recently published in Geophysical Research Letters. "Historical records of solar activity indicate that solar radiation has been increasing since the late 19th century. If a trend, comparable to the one found in this study, persisted throughout the 20th century, it would have provided a significant component of the global warming the Intergovernmental Panel on Climate Change reports to have occurred over the past 100 years," he said. 
So what you attribute to an industrial revolution starting in only a handful of countries can also (and probably more scientifically plausibly) attributed to a global increase in received solar radiation during that same period of time. Jus' saying |

| holysaiyan1 mate, two of your links are broke - the Jupiter and sun ones. The others are pretty interesting though, but I know for certain that warming on Pluto isn't linked to what's happening on Earth. Its due to axis change and it's funny orbit. (Its in the article ) Any your right, If we were heating up like Triton, we would be boned. I hadn't heard of the climate change there before - you learn something new everyday. As for where I sit on the issue of Global Warming, I'm on the worried side. Australia's weather over the past few years has been really fucked up and we can't seem to be able to blame it on phenomina like El Nino. The most damning evidence for a man made cause of most Global Warming comes from ice core samples from Antarctica. These samples show that concentrations of CO2 are in their highest point in 650,000 years. It's hard to blame that on the Earths natural cycles between ice ages - an interglacial cycle lasts about 150,000 years. This rise in CO2 seems to carrelate with the start of the industrial age. Coincidence? |

| I actually don't believe in 'global warming'..My 6th grade schoolteacher gave me this large packet with reasons why global warming doesn't exist, and prrof that it was just a hoax... So I float along without worrying about it for the most part! |

| Weird weather changes are taking place on some of the other planets in the solar system as well. Mars appears to be entering a phase of warming, as well. Jupiter has lost 2 of its 3 formerly perpetual White Oval storms to climatic change. If the Earth was experiencing climate change at the same rate as Neptune's moon Triton, we'd be majorly boned. Pluto's temperature has tripled in the last 14 years, and its air pressure is rising as well. The possible cause for this cosmic crisis? The sun is emitting more energy than usual. |

Perosnally Im not worried because I'd probably be dead before anything bad really happens. But I do think its a major issue and people should care more than they actually do. Is it right that we are heading for another ice age?
Yes. If the Grenland-ice melts the Gulf streems will stop, and it will become colder and colder. Ice ages can actually come pretty fast too. The assumption is 10-20 years. |

| It's really sad because we could still have an efficient (if just not smaller) economy that would help to reduce global warming and it could be easily implemented within 10-15 years. |

i'm really worried about it. if we dont take care of our environment it's going to get worse and worse for our children and our children's children.
i believe we are already at the point of no return... we need to stop trying to patch the "boo boo"s of the situation. [merely prolonging the inevitable] we need to find a FIX for the problem. lowering emmissions and polluting less will only delay what will eventually happen.. we need to [somehow] rebuild and reeforce the Ozone.. otherwise, theres really nothing we CAN do. |

| ok listen up. global warming is natural, whoever said governments should take action obviously know absoultely nothing. humans have no impact on the rising temperatures. the reason temperatures are going up is because right now the sun is the hottest its ever been for the longest period. by 2012, the sun will have expended all the engery and we will go into a global cooling phase that can last anywhere from 50-200 years while the sun stores its energy for the next warming trend. people, please stop listening to the media tellign u that HUMANS are the reasons for global warming. there is no sceintific evidence that says C02 emissions are the cause for global warming. if anyone cares, the ice caps on Mars are melting now too....humans or the sun? you decide. |

I know yea! wot makes it worse is that governments dont seem to be doin anything majorly about it ( if that makes sense) there more worried about this fucking war in iraq than global warming which is probably the bigger threat |
