I am worried about global warming. Fearing an end of the world scenario. I am an old man and will probably die before the end of the world due to climate change.
I wouldn’t worry about it, the world has warmed and cooled before. Better warmer than cooler

The world will be fine, its just us who live on it that will be f***ed

The people sounding the alarm about global warming say the science is settled. Ninety-seven per cent of climate scientists say that global warming is real, and it is man made. It’s hard for me to believe that we can burn 20 million barrels of oil a day in the U.S. alone and not affect the climate. Look at China. The air is practically unbreathable in Peking because of coal fired electricity generation plants. The bad part is that there has been major breakthroughs in renewable energy, and we’re going to poison our water supply with this fracking. Solar energy is competitive with fossil fuels now, but we’re not going to pursue it because of this fracking.

Well some people believe it is about implementing a carbon tax.

I will be gone before the world ends, but the world has warmed and cooled before, not sure what will happen but mother earth will not be able to handle all the activity that a larger population will bring with it.

It is getting unseasonably warmer in the summer. Spring begins sooner than I used to remember it. Sea levels are rising. Melting permafrost and glacial minimum is happening everywhere. We are seeing the beginning of something massive.

I’ve done meteorology at university and I agree 100% that climate change is happening and is man made. Whether this affects you or not depends where you live in the world. The poles are getting warmer due to ozone depletion here, however mid latitude areas (areas between 30 and 60 degrees N and S of the equator) will not see temperatures rise as fast, relatively, to the poles, due to lower depletion. Overall on average the temperature of air on the earth is for sure rising and higher air temperatures means that the air can hold more water vapour, higher water vapour content is directly linked to more intense rainfall, though not all areas will see a rise in rainfall. Areas near the equator will see rainfall levels rise as a higher surface temperature means more convection and larger clouds which would bring more intense rainfall. However climate change at the mid latitudes (between 30 and 60 degrees north and south of the equator) is linked to the jet stream. The jet stream is a relatively narrow ribbon of air that circulates round the whole earth, anti clockwise in the northern hemisphere and clockwise in the southern hemisphere, at about 9-16km above the earth and travelling at speeds up to 200mph. It forms at around 50 and 70 degrees north and south of the poles, and forms due to temperature differences between these latitudes (relatively warm between 30 and 60 degrees N and S of the equator and relatively cool or cold between 60 and 90 degrees, N and S). Differences in temperature leads to differences in pressure and it is this difference in pressure that causes these winds high up in the atmosphere, called the jet stream. Now the reason why the jet stream is important in explaining global warming is because we know that the poles are heating up much quicker relative to their counterparts in the mid latitudes, thanks to ozone depletion. Over time this means that even though overall temperatures are rising over the world, temperatures between 30 and 60 degrees N and S will not rise as quickly, relatively, as temperatures between 60 and 90 degrees N and S. This gives rise to a decreased temperature difference between these latitudes. Decreased temperature differences results directly in decreased pressure differences which then results in less air flow between these latitudes, this air flow being the JET STREAM (air flows from high pressure to low pressure). As the jet stream flow slows down this means the speed of the jet stream also slows down. Now if we know that the jet stream naturally meanders north and south between these latitudes, the amount of meander depends directly on the speed of the jet stream. SLOWER jet streams meander more, just like slower rivers on flat ground meander more than fast rivers near hills or mountains. As we know the jet stream is naturally starting to slow down thanks to these decreased temperature and pressure differences I talked about before, we then know that meanders in the jet stream are much more likely in the future. The thing to know now is that meanders in the jet stream cause heat from the south to flow north and cold in the north to flow south, the heat that flows north is called a ridge in the jet stream and the cold that flows south is called a trough. More occurrence of these troughs and ridges means more occurrences of warmer, and also colder, than average temperatures for that area. So if you are between 30 and 60 degrees north and south of the equator, expect higher summer temperature but also lower winter temperatures in the future thanks to these greater occurrences of meanders in the jet stream. However if you think that rainfall will increase if you are between these areas too then you are wrong, meandering jet steams tend to stick in a certain position for longer periods of time, which is linked to how slow the jet stream is moving. Slower jet steams tend to stay in their position for longer than faster jet streams. This means that we are likely to see longer periods of dry weather when a ridge reaches a certain area (high pressure) and longer periods of wet weather when a trough reaches a certain area (low pressure) however these types of low pressure will bring less intense rainfall.

While there are many unanswered questions, it is quite likely that industrial pollutants are a contributor to global climate.

I know I’m a minority on here but there is so much fine tuning in this world I’m putting my faith in the one that has done all that fine tuning to make things tick in the first place.

I am worried about the coming generation of children who will have to live with this problem. I think it is wrong and a mistake to bring children into the present day world. Thank you all for your comments.

I’m on the fence about it. Yeah they say that a majority of scientists believe in it. I heard though that they what they believed is that carbon dioxide is a greenhouse gas. There have been some intelligent people that have come out against it too. You usually don’t hear about it that much though. The reason being is that the science is heavily politicized. For example why haven’t the predictions that they have made come true? The earth’s temperature should be much more than it is now. Anyway not a climatologist just someone that has heard intelligent people on both side argue one way or the other. I even posted a video about a nobel laureate in physics stating why he didn’t believe it. Just mentioning that because most people believe that global warming is true so they go with that. Counter opinion.

Not worried about it. We’re in an inter-glacial period, warming will likely turn out to be a good thing. More concerned with pollution and over population.

Yes…Where are the enormous sea rises we are told to expect?
It’s true that we are in an ice age of sorts. But we have been there for the entirety of human civilization. Coming out of it is not predicted to be a good thing for our species.

What about how the temperature records were adjusted historically to make it look like it warming but is in fact not. Have you see that data? I’d be curious as to why that was done
It is a problem. But there might still be time to fix it. And don’t listen to people who say it’s happened before. This is an excellent resource on that from an unlikely place:
