Since the industrial revolution, humans have been altering this process by adding more carbon dioxide to the atmosphere than plants can take up. That’s driven carbon dioxide levels higher and with it, global temperatures, along with a host of other climate change impacts.
Quote:
In the centuries to come, history books will likely look back on September 2016 as a major milestone for the world’s climate. At a time when atmospheric carbon dioxide is usually at its minimum, the monthly value failed to drop below 400 parts per million.

Check out the moving graphic, scroll down a page and you will see it, showing how carbon dioxide moves. Global warming is a misnomer though, I think people should think of this as... well look at Japan for instance, 6 Typhoons in one year. Or say, negative 50 faren in Indiana winter two years ago... I think "intensity of seasons due to climate change due to carbon monoxide levels outpacing ability of plants to absorb it" is sort of a better saying... saying global warming, the common man in winter will say, well I don't see it.

It just needs to be explained better imo. lol (yes I know my explanation isn't that great either"

If you look at that graph and think about it logically, look at the Amazon Rainforest region... imagine if that ever gets overwhelmed with red... I honestly think that would be the last lung of the Earth gone, compounding interest of carbon, and rapid change climate speaking. You can sort of see as the graph moves through its timeline, the Amazon Rainforest almost looks like a lung breathing... interesting. thumb.gif

Is my description of climate change off? I honestly don't know, I just know global warming is sort of a weird term to describe it all.

Also, PM with part of Ireland your from! I need someone to drink Orchards Thieves with! :DDDDD

Not you the topic. Yes, its permanently over 400ppm. Climate doesn't change, ppm doesn't fluctuate. Carbon Dioxide is the thermostat for global climate warming change, blah blah blah. I'm more worried about pollution and man cutting down the rainforest than this nonsense, personally.

I get where SA is trying to go with this, but their timescale is off by about 11000 years. When large scale farming and domestication took off with the Neolithic Revolution. Combined with slash-and-burn technique that became widespread 6000 years ago, humans have directly and indirectly contributed to CO2 (and other greenhouse gases such as CH4) for millennia.

I'll grant them that the industrial revolution turned that from a linear rise to an exponential rise in CO2 and other gases. This 'Since the industrial revolution, humans have been altering this process by adding more carbon dioxide to the atmosphere than plants can take up,' sentence is a bit of a farce when you track atmospheric conditions via ice core samples though.

The 400k year Vostok sample is the easiest to read, but you can see atmospheric content of CO2 and CH4 track up starting ~10k years ago.

The 2K year Law Dome sample shows the effect of the industrial revolution and the linear to exponential shift.

There are 2 kinds of people that deny climate change:

Those that make a lot of money by what could be causing it.
Those that are afraid that it's true.

And those who see all predictions made by global warmers have failed to pass and the models warmers use don't even take into account the SUN with regards to climate. Beyond retarded. All predictions wrong, don't include the sun, but very credible. Oh and caught cooking the numbers too.
Oh and seen as global warming wasn't working, changed to climate change, because ya know, without humans, the climate was always the same.

Friends of government get a pass on the carbon tax to "fight" global warming, smaller companies get raped and competition of the largest companies go out of business.

Whilst actual pollution continues unchecked and rich people flying around in private jets preach to cut your carbon footprint.

The only logical course of action from here on out is global depopulation. Time to bring out the suicide booths.

I just looked BulletBait's graphs, checked other sources, found the same info presented by credible sources (often scientists.)

To me this is a question of faith in certain scientists / politicians, not a question of faith in science itself. It's not even a question of faith in climate change; it's a question of faith in human-caused climate change. And if this climate change is human caused, it's a moral question and a question of realism surrounding the way people plan to deal with it.

Population control? Deny energy to developing worlds? Reduce our own energy consumption and risk becoming economically or militarily weaker than other nations? By the way, what if those other nations don't believe us, and will only end up buying up fuel that we decide not to?

What if we lose our influence and can't force China / Russia to adhere to our plans to stop global warming? If it truly is a question of survival for the human race, do we stop them now? If not, when?



No, people who deny or question human-caused climate change and the implications of it are not just scared. They're not just worried about their money. They're worried about faith driven decisions, when those people asking for our faith are not giving us realistic information to make decisions.. yet still forcing us to make a decision.

Not as simple as you want it to be. The world isn't sunshine and lollipops; if we aren't being given information about decisions, we need to remain skeptical about the implications of passive approval. We need to know what it means to fight climate change. It does not mean magical free energy. To some, it might mean eugenics, or genocide. To some, it might mean food can't be delivered to their bustling populations. Fossil fuels are a product of American industrialism, which is a product of American freedom, which is a product of rebellion against the British Empire, which many still view to be a reckless thing that led to THIS destabilization of the world.

I'm not saying that's a good point of view, I'm saying that people abroad might hold this point of view. Possibly certain religious extremists, or maybe entire countries who fought against American influence just in the last two world wars.

Global warming is kind of a big deal when you're in China, Russia, The Middle East, Argentina, Vietnam, South America, Cuba, Ukraine, Turkey.. I don't know? It's a long list of people who rely on America to keep the oil flowing to their country. The thought of American politicians and possibly military viewing global warming as a threat to America.. that MIGHT cause certain world leaders to be concerned about what America will do as the world's military, economic, and energy superpower.

Or maybe it's just that climate denying is stupid because science.

The word you're looking for is "Climate Change". Global Warming is considered a redundant term, as not all climates get warmer as a result of climate change.

For example, melting sea ice is weakening the gulf stream, which may cause the UK to actually get colder as the gulf stream is a transatlantic current of warm water.
