This documentary says otherwise. Just look at what some of the reputable people interviewed in it have to say, right at the very beginning.

https://www.youtube.com/watch?v=oYhCQv5tNsQ

Climate change fluctuates initially because of the sun and it's variable output. Clouds and carbon, etc, follows as a result, so they explain. They even bring to light the politics behind it, which we all know politics has it's hands in almost everything.

The title of the video is a little misleading, as it doesn't try to disprove climate change, it just explains the main factor is not carbon as we've been told.

That's pure bullshit. If it were true then the earth would be cooling off for years again, as solar activity is very low right now.

Solar activity is cyclic, every dozen years or so the sun switches between high and low activity, but the climate doesn't follow suit. The melting isn't stopping (which it should have by now according to that theory), it's not getting cooler, the sea level continues to rise (even outside of the melting due to thermal expansion, the warmer the oceans, the more volume they take)...

That "documentary" had been largely criticized by most climatologists, and also some scientists appearing in the flick who got quote mined and misrepresented.

If you live in the west then the effects of climate change are unlikely to be felt in your life time. I wouldnt worry about it or waste my 'energy' trying to save energy.

The changes are already felt in Europe, where the summers keep getting hotter and dryer. Forrest fires were extremely rare 20-30 years ago, now you get several each and every year.

In the US, it's mostly felt in Miami and New Orleans which are fighting against drowning from sea level rise. Miami has puddles of saltwater in some streets at high tide due to seawater flowing through the sewers and spilling up into the streets. New Orleans is subsiding on top of the sea level rise, the wetlands around the city are shrinking as they get filled with saltwater. Another Katrina would pretty much make the city unhabitable.

I don't know if you have a family or even kids, but if you do, would you really want to leave a wasteland for them since you couldn't care for the future?

I dont have any, and dont have interest in having any. Yeah Miami is going down, but the US is a big place and there's a lot of land those people can move to. Here in the northeast we're going to have much milder weather than we did before - we already do. So there's trade offs either way. Keep the status quo and the north remains a cold wasteland, while the south remains nice and warm. Or we can let things take their course and make the north more hospitable and let the south dry out. Since I'm up north I'll go with the latter.

But I don't wanna be responsible for the next generation being screwed over.

Atmospheric Carbon is the primary regulator of Earth’s average temperature. Reforestation would allow more to be filtered out of the atmosphere, but emissions would still need to decrease to ensure a net loss of atmospheric carbon. Responsible leaders who accept the conclusions of peer-reviewed scientific papers as outlined in scientific literature will be necessary. The Left has a near-monopoly on the right people and the right ideas to do what needs to be done.

This is why I miss Obama. -_-

Nothing and just relax. Every winter are announced as exceptionnal, like summers.

If we have a too cold winter --> it is because of the climate change

If we have a too sweat winter --> it is because of the climate change

If we have a too cold summer --> it is because of the climate change

If we have a too warm summer --> it is because of the climate change

 

Believe me if you just stop to think about it you will have plenty of new freetime in your mind and less stress. We have no influence on the climate as individual citizens.

Yes I don't believe at all into global warming, like Trump.

Get with the times. It was global cooling, but then it started warming. Then, it was global warming, but then we had a pause. Now, it's climate change. So no matter what it does, they are right and we need to give them tons of power and money to fix the problem. 

You can't be serious. -_-

I know it's probably just a dream at this point, especially with idiotic decisions by, ahem, a certain Western superpower since 2016, but it's still a nice thought to have.

Are there ways, any at all, to reverse climate change? Would it help if we planted new forests, reduced our garbage output, used more renewable energy sources, invested further into water bottles and re-hydration stations, etc?

I try my hardest to help out, I'm even trying to use lights that are more energy efficient. What else can we do?

That actually makes a lot of sense when you think about it.

Volcanic ashes cool down the earth. A couple of nukes can set off the big one. Big problem, big solution!

If you're not going to take my concerns seriously then get out.



Changing human behavior is hard, very hard. Using more energy efficient lights is not going to make a dent. Energy consumption keeps going up with more and more electronics getting used in every day life.

Things that will make a difference are a break through in Fusion power, more nuclear power plants until then. More electric vehicles. Switching cargo ships to clean hydrogen for fuel source, as well as trucks. Electrify the rail network and build high speed rail lines to replace domestic air travel. Develop roof tiles with built in solar panels and make them mandatory for new housing projects.



Some people need to realize that climate change has always existed on earth since the forming of our planet, besides the political fuss its also just a scientific fact and it just might be of importance to limit our minor or big impact on it since it would be hard for humanity to adapt on a grand scale if temperatures change drastically in a short timeframe . "Reversing climate change" is a weird term since its just an ongoing forever happening thing but it could go slower .
It might be more stable then we think it is but its just good to be sure and live greener and healthier.

As I said before, reducing input of sunlight is one way to fight the change. Not that we really want the nuking and all. Also hard to balance this right, too much and it gets colder.

Another option is to build a solar shield / mirror the circumference of the earth at the Lagrange point between earth and sun. Huge LCD shutter glasses to control how much light can get through :) Of course with current tech no chance.

I wonder if solar panels provide cooling. They keep your roof 3c cooler, yet that's just preventing the heat from reaching your roof. Do they actually convert solar heat to energy? I'm guessing using mirrors to focus sunlight at a central point to turn water into steam does take heat away. You probably need to cover the entire desert with these to make any kind of difference.

No, solar panels don't cool on a global level. The reason is pretty simple, the solar energy is already at earth. If you don't want it, reflect it (ice caps keep the balance low, if ice and snow is melting the earth absorbs more energy). But for obvious reasons you don't want your solar panels to reflect light.

You might have a local cooling effect in the shadows of a solar panel though. Not sure about that.

It's true that climate change happened in the geologic past. But usually over tenthousands of years, not in decades. Such fast change never happened before.

Fast change did also happen before and was mostly invoked by massive vulcanic eruptions,releases of big amount gasses ,changes in jetstreams and ocean currents. 

But i agree we most likely have a big impact on the current state and must do what we can to lessen our footprint as a species on this earth if we want to keep this an environment we would like to enjoy for the coming thousand years.

Such changes as you describe only had local changes (local can be a whole continent in this context, but still not the whole earth), and it often was temporary.

It's not stoppable or reversible anymore (maybe in the 70s or 80s), we can only try to slow it down to have more time to prepare for the consequences. I think mankind won't change much unitl a large part of the economic power will have to be used for technology to secure our survival.
