Earth’s climate is changing in a big way, and it’s because there's more carbon dioxide in the atmosphere than at any point in our species’ history. But Earth’s climate has changed before. How do we know that this time we’re the cause? We know thanks to tiny bubbles of ancient atmosphere trapped in ice. #climatechange #globalwarming

It's Okay To Be Smart lets fix it by making extremely large wind/solar farms and destroy all the trees on earth. Cause trees arent part of the agenda

[@MsCherade9]

@@ltok4695 What's the correlation between solar and wind farms being created, and cutting down all the trees? I can't see the connection there.

[@ltok4695]

MsCherade9 do you realize that if we entirely cut off all fossil fuel power generation and shut down all of our nuclear plants, like many 2020 us presidential canidates suggest, that our best clean energy solutions are wind and solar. Both are very inefficient and will not work all the time ie, cloudy days/windless days. We would need giant battery farms. Using america as an example, the east coast has alot of trees, solar farms dont work in the shade, wind cant blow efficiently through the trees. We would need to cut down many trees for that. Also since the technology is inefficient we would need alot of these power generation types. Now just do that all over the world you get my point. Im no expert but thats common sense. Nuclear energy is the best option for “clean” energy. Until our other clean energy technologies get more advanced it is not possible to achieve the goals that activist want. Until nuclear fusion power is readily available we have to use fossil fuels.

[@Eric14492]

@@ltok4695 Trees are definitely part of the agenda and are a major way of reducing CO2. Wind and solar do not need to destroy any trees, and very rarely significantly do. The major cause of deforestation is agricultural expansion. If everyone would have one meatless day a week, it would have a huge impact.

[@msyemaya]

I watched a documentary a while ago about our ice core samples, it was by Gregg Braden. In that doco the ice showed that the rise in CO2 happens AFTER the Earth's temperature rises, so if CO2 causes global warming, why would that be the case ??

[@talroitberg5913]

My non-expert answer: there are feedback mechanisms. CO2 causes warming, which causes the release of even more CO2. For instance, there is a lot of organic carbon locked up in permafrost, which can be released when the permafrost melts. There's plenty more carbon in boreal forests, which can burn when they warm up.

[@BrentonSmythesfieldsaye]

CO2 concentration in Earth's atmosphere can either lead or lag temperature change depending on circumstances. If this "Gregg Braden" has only explained that CO2 lags temperature, then he has not told the full story. Why would that be? Why would he tell only part of the story and thereby mislead people? For example CO2 lag events can be associated with transitions between glacial and interglacial phases. The topic of CO2 leading or lagging temperature change is well understood and documented in the scientific literature. There is a very good article at the skepticalscience Website that explains the CO2 leading/lagging temerature aspect very well for average citizen to understand. Do a search at that site for "CO2 lags temperature - what does it mean?" The content originates from vocationally active climate research scientists. A word of advice if I may. The best and most definitive scientific facts surrounding the topic of anthropogenic global warming and climate change are to be found in the peer reviewed scientific research literature. Not from social media platforms. For genuine science based content that can be better understood and trusted by the average everyday person, please check online sites such as NASA, NOAA, UK Met Office, CSRIO, skepticalscience and climatefeedback, as just a few examples. Cheers

[@ianrowley5762]

@@talroitberg5913no because there has to be a temperature rise first which releases more of the 0.04% of CO2.

[@vladimirdavidovic4438]

Short answer is that CO2 is only one driving factor of change in climate. Throughout history other event such as solar radiation, earth orbit etc.. did impact Earth temperature quite a lot. With this warming driven by external factors, water evaporated, glaciers melted and stuff burned thus driven CO2 up.

[@BrentonSmythesfieldsaye]

CO2 changes can lead or lagg temperature change depending on several other factors in play at the same time. You have been duped by this Gregg Braden giving you only half the story. This is clearly an example that confirms, the only place to get defnitive answers is the actual scienctific literature. That is actually where the genuine research/evidence based reliable information is found. Not in "documentries".

@w9j15g It may be possible to get away from using fossil fuels, but the solutions currently proposed do not work and would bankrupt our economy. The only source of power that could realistically replace fossil fuels is nuclear power. Either nuclear fusion or nuclear fission. Nuclear fusion would be the best option, but it may be a long time before that technology can be developed. Nuclear fission is already something that can be done, but we still need to solve problems such as dealing nuclear waste. Either we need cleaner nuclear power plants that don't produce it, or we need a better way to dispose of it. Once that issue is sorted out, we could build enough nuclear power plants to provide all of our energy needs. That would not only not bankrupt our economy, it would likely stimulate it. All while being much friendlier to the environment. Solar, wind, hydro, and geothermal power are useful in some cases. They work well in some specific locations, but they cannot provide more than a small fraction of our energy needs. So the people proposing replacing fossil fuels with them are either out of their minds, or are not serious about solving the problem. Likely their agenda is political in nature rather than environmental. And since this is completely obvious to any sensible person, those people are currently being ignored.

[@TerryProthero]

@w9j15g Either the goal is to get away from fossil fuels or it isn't. And I'm not suggesting sitting on our hands. I'm suggesting doing something that could actually work. Not to waste trillions of dollars on something that can't possibly work. And I'm in no way underestimating what solar can do. It can work rather well in a few small cases. But it cannot even come close to providing for our nation's or any other nation's energy needs. Try doing rooftop solar in New York City and tell me how that works. It's a completely moronic idea. Nuclear works anywhere, and natural gas is cheaper and cleaner than any other fossil fuel. So it's definitely an improvement. Officials are probably against solar because it's expensive to implement, and doesn't produce much power. They actually care if a proposed solution works. The reason people like fossil fuels has nothing to do with politics. Fossil fuels are a cheap and abundant energy source which can be implemented with existing technology. A big reason for that is the high energy density of fuels like gasoline. Because of these advantages, fossil fuels are very difficult to replace. An alternative has to provide a similar amount of power at a similar price. And nuclear power is the only option available to us that even comes close. We simply don't have the ability to produce the required power any other way. Propose things that actually work or no one is going to take you seriously. That's the bottom line.

@w9j15g I have never worked for the nuclear power industry or the fossil fuel industry. You clearly can't dispute anything I have said with facts, so you are trying some personal attack.

Good question! The oldest ice core I know of is 2.7 million years old. Because of bedrock heating and glacial flow, we likely can't find ice cores dating much farther back in time than that.
