    we have enough data to conclusively prove that the temperature is going up. there is also a consensus that human induced global warming is about 0.4°C - so far. most also agree that our climate models are not good enough to make reliable predictions, which is why scientists are worried.

    very good presentation of the whole topic: http://webcast.berkeley.edu/course_...d=2010-D-52040|2010-D-69342&semesterid=2010-D
    lecture 19. if you want to know more about physics, to pwn your friends and people in this forum, watch all lectures

    Ya'll should be less worried about Global Warming, and more worried about what's to come in the next several years...

    Climate change is real for sure, the causes of how ever are debatable.

    After all we've had both warmer and cooler times on our planet.

    It may not be due to us that it's happening now. ( but could be heh)

    To be honest, probably not doing our self favours by cutting down so many trees.

    agreed.
    that's what i have a problem with.if our models are inaccurate, how is there a consensus
    with a specific number assigned to our impact. we simply don't know enough to accurately
    measure that.

    i don't debate the warming, i debate the human influenced part. and it's more as devil's advocate.

    i think it is more likely than not that we do affect temperature. how could we not with our industry
    and building and pollution. but what is it that tells us conclusively our impact on it?

    i will surely watch those. i love ted and use MIt open courseware often, Berkley is a fine addition :)

    Jesus? But he told me to live in the present. Unless you're speaking of Santa Claus, he hasn't visited me since I was 12 and I miss him. :(

    Anyways global warming is real. We do not need to take drastic measures to do anything about it. I think if we individually gave a damn about what we do to effect the environment that will be all that's needed.

    Quoted for truth.

    Shame so many humans can't fathom that.

    and whether you do believe we are the cause or not, there is no reason NOT to take care.

    The underlying global temperature has continued to rise, despite the fact that solar irradiance for the past few years has been stuck in the deepest solar minimum in the period of satellite data. Once Solar Cycle picks up to a normal level, I think we will see global tempatures rise at even faster rate than they already have been in the past 100 years.

    Just a quick thought as others alluded to on the first page . . .

    If the question was:
    1) Do you believe in climate change?
    Yes, anyone who says otherwise is a lunatic.​
    2) Do you believe in [anthropogenic] global warming?
    It would be an empirical fallacy to say that some amount of anthropogenic global warming is not occurring.​

    In a lot of ways climate science is in it's infancy. Science takes time and contemporary climate theories need refining.

    Whats the holdup with launching GoreSAT?

    Further to that, although I know many to not like iTunes, I ahve an iPhone, so use it ALOT.

    iTunesU carries many university-level courses, from start to finish, in video format, from universities around the globe. I enjoyed many a lecture while flying across the country earlier this week.



    ON-TOPIC.

    Since I am one of the most northerly TPU members..well..it's been colder than normal as late, with far more precipitation than ever before. You know the rhyme "April showers bring May flowers"?

    Yeah, try May showers.


    Weather, and the sun, is affected largely by an almsot 11-year cycle, and I've lived here 12 years. While weather has definitely changed over that time, until I've bene here for another 12 years, I hold no real opinion on this subject.

    Because, really, if climate change data is accurate, we've long since been past the point of no return, and nobody is really making any efforts to negate teh effects daily life has on our environs.

    And now that I've geeked out a bit, I'm going to bed. :laugh:

    I'm a skeptic because there's really only 40 years of good (satellite-based) temperature data.

    Yes very much so, but the government/me cant do anything about it unless your rich. ($20grand to install solar panels)

    I have lived here for almost 30yrs and i can tell you that it has only got hotter and hotter yr by yr, less snow each winter that we basically have NONE now. Also the drought that lasted 10yrs and is technically still going is enough proof to me that global warming is real.

    How old is the earth? How many Ice ages has it had? I think its fair to say its getting hotter. And than its going to get cold. 10 years / 100 years / 1,000,000 years this is a drop in the bucket in the life of this planet. Maybe we have impacted this. Ok, what we have done to this planet is disgraceful. But it can recover. Look at all the oil in the golf. Were did it go? We just need to use common sense. IMO I dont think we will impact much by buying different light bulbs.

    I didn't know there was oil in golf balls :p It just sank to the bottom of the ocean, that's where it went. Just like most of our crap. Lightbulbs will not do much, but in a case where everything little helps, I think it can go a long way in reducing our energy use.

    The problem is that sometimes switching to the "energy efficient" product actually ends up wasting more energy and creates a worse negative environmental impact due to factors we don't take into account. Such as the weight of the product and it's size compared to the non energy efficient unit (transportation energy costs), plus the materials used to make the efficient product may do more damage to the environment from extraction and disposal and or require more energy to extract and transport.

    So while you can reduce your energy usage, this in no way means it is having any affect at the global level.

    "Green" technologies are essentially just a marketing ploy. You can, however, save energy in more simple ways, such as using natural light during the day, turning your computer off when you're not using it, etc.

    I think climate change is a serious problem, but not an insurmountable one. I think humanity should focus some effort on it, but more importantly focus effort on space colonization, so if we screw up Earth we have somewhere else to go. :)

    Ok, Saying the earth is getting warmer and is headed for a catastrophe based on 100 years of research is like saying the worlds oceans are draining based on 1 hours observation of natural tidal movements.
