Sydney hits record 45.8 deg

I know people have asked you about 500 times but when you use the term climate change denialist it's can you mention (man-made) climate change as some people aren't denying climate change, but that man is the cause.

I am sure he does it on purpose, first it was man made global warming, then global warming now it's man made climate change or climate change but alf is spot on please distinguish between man made climate change and climate change. Global warming is no longer used. Climate change or man made climate change.

The climate is obviously changing, no one is denying that. Some people do not have faith that humans are the cause like you do ghoti. We know very little about our planet and this sort of climate change could have happened in the past but it could also be man made but you have to stop calling people mentally ill or stupid because we may not agree that humans are the cause. Most of us are open to the idea that humans are the cause but we can also see there may be other forces driving the change where as you don't believe for one second there could something else causing the rapid increase. You ignore the sun entirely, the very thing that gives us life you rule out.

It's fine to have your opinion and have belief in man made climate change but you have to look at other options as well. Ok you never will but we will continue to question the man made aspect.

By definition a denier is someone who tries to say that the climate change we are having right now is not man made. I don't think anyone argues that it hasn't got hotter over the last 36 yrs, especially the last 14 years.

Because most people do not understand the science it is easier for the climate sceptics to get the message across by using staw men.

BTW, re that volcano thing. If hypothetically 10 volcanos all around the world erupted in the same year without any smoke plumes then the heat effect on the average global temperatures will be infinitessimally small and not of the order of what we are experiencing. Yes, previous climate changes may have ben caused by volcanoes but it is the affect of the insulation from plumes.
Now, we have not seen this type of volcanic activity in the period we are dealing with right now. I think vulcanologists know pretty well where the active volcanos are.

BTW BTW...today it is 19 deg in Sydney and now sprinkling rain...does that mean the global temps are going down. No. We know the average temps here, in USA and around globe are trending up.
Hot days like yesterday and cold days like in N Hemisphere now are both the result of global warming.

Can you tell me where that is happenning to create this pattern?
At the moment we have definite measurements of CO2 content and other gases in abundance due to industrial activity...we know that. We also know the temperature trends plus other global warming parameters that people don't know about...we know this.

I am willing to listen to logic too



Yes, yesterday and last Tuesday with the northwesterly had humidity in mid teens and when you got out of car it "wow, that is hot" but not sweaty.
When we have the usual high temps of say 30 in city and 36 out west i.e. sea breeze then the humidity is high and it is less bearable.

The only reason I am writing this post if because I know you have the ability to understand the science if you look at the information so its late at night and I wanna show you the evidence.

Fact: CO2 is a greenhouse gas. They cause the earth to increase.
Fact: CO2 levels are increasing quickly.
Fact: We are taking CO2 out of the ground and putting it into the air.

To argue that this is not the reason, you need to show us A) CO2 is not increasing or B) CO2 is not a greenhouse gas.

Its kinda really that simple.


But you said you are willing to listen to logic. Is it logical to assume you know more about climate change than the combined ability of just about every respected climate scientist in the world, and every respected scientific institution in the world? Without having any training in the sciences?

I wouldnt even begin for a second to pretend I know better than all the scientists and governments around the world combined. Either you really are a savant with insight missed by everyone, in which case you deserve a nobel prize...

Or a person who claims better is an egotistical idiot who doesnt realize how stupid they are and you are being used by big oil and big coal (this is not directed or insinuated at you and is completely general).

If you really think you have an argument, please see this website: http://www.skepticalscience.com/argument.php

It deals with the most common lies, arguments and perceptions of climate change denialists.

How many of these can you spot in this thread?:
View attachment 36026

For instance, that climate change is "natural".

- Is global warming part of a natural cycle? No: http://www.skepticalscience.com/global-warming-natural-cycle.htm

One of the most common lies told in this debate by one of the forums bigger fibbers is that global warming is caused by the sun (yes, we all know the sun warms the earth and is the source of our energy, but its not the reason for this temp increase):

http://www.skepticalscience.com/solar-activity-sunspots-global-warming.htm

Im sure if you read back in this thread you can find the false argument about how the planets warming is somehow evidence that its the sun. As per usual its false:
http://www.skepticalscience.com/global-warming-other-planets-solar-system.htm

Finally, yes, we are causing the CO2 : http://www.skepticalscience.com/human-co2-smaller-than-natural-emissions.htm

EDIT : Has the "Antarctica is gaining ice argument been used yet? http://www.skepticalscience.com/antarctica-gaining-ice.htm

I have just watched a very interesting video by a guy that really seems to know what he is talking about.

Anyway, he says:

1. CO2 is at it's lowest levels in 600 million years, even if we have recently experienced spikes in CO2 levels.
2. The earth's magnetic shield is weakening - this has been happening for the last 400 years.
3. Earth is overdue for a reversal of its magnetic fields.
4. The magnetic North is moving at a much larger rate than it has before.
5. Space Weather has a far greater influence on our local climate than people realise.
6. We should be more worried about Solar Flares than climate change.

Here is the video: http://www.youtube.com/watch?v=Xcm9qsVaf0o&feature=youtu.be

He has a lot of other videos that I am also watching.

Ghoti, I am looking at the information you have linked for me. I will report back once I have looked at everything, including the other videos from this guy I just watched.

EDIT: He also states that Methane is 25 times more potent at affecting Greenhouse effects than the equivalent amount of CO2.

There are a lot more than 10 erupting volcanoes globally at this very moment, 23 to be exact. With a lot more showing activity.

Volcano activity of January 18, 2013

Larger eruptions actually contribute more to global cooling than global warming.

In the Historical cases one can see how a single large eruption affected global weather patterns.
http://en.wikipedia.org/wiki/Volcanic_winter

Case in point, read the consequences to different parts of the world.
http://en.wikipedia.org/wiki/Laki#1783_eruption

The amount of SO2 released by volcanoes is much less compared to man-made sources but the impact of some eruptions might be disproportionately large. The gases emitted by most eruptions and by man-made sources never leave the troposphere, the layer in the atmosphere from the surface to about 10 km.

However, volcanic gases reach the stratosphere, a layer in the atmosphere from about 10 km to about 50 km in altitude, during large eruptions. This relationship is complicated by the fact that the elevation between the volcano summit and the distance to the troposphere/stratosphere decreases with latitude. So, some smaller eruptions at higher latitudes can eject as much SO2 gas into the stratosphere as larger eruptions closer to the equator.
