Climate change is real...weather patterns are shifting and it's the future generations that are going to suffer....
Not what we want to hear but it has been Scientifically proven that we are heading up shit street. Major steps are needed to be taken to avoid the inevitable catastrophies that have been predicted.
Easier said than done as most people don't think of tomorrow.
The Shop
We need more Co2, it is the life blood for living things on this planet, the foundation for life. It has a small warming effect on our climate but we may have reached a saturation point; and the amount from human involvement even smaller effect yet.
The climate is not doing anything unprecedented, and there is not extreme change going on.
At this moment we are in low sunspot activity which effects our jet stream pattern, causing warmer air to travel further from the equator, and cooler air from the poles to travel closer to the equator.
To sustain the amount of life(humans) on our planet we need more Co2. This will help green the planet, help crops grow with less dependence on harmful fertilizers we currently use to make up for the lack of Co2.
lower than about 200ppm plants start to struggle, below about 150ppm life dies off.
The real threat is global cooling.
This a take I wasn't expecting
The past few months it's really been cooling down in Cape Town...we are in middle of effing winter and I'm ducking off to bed now before my nuts turn blue.
Ps. One of my best mates believes the earth is flat and I bet he also believes in Global cooling..
Think of it like water. We all need water, but there is a point where it is toxic. There will be a point when the CO2 level rises enough that we are not able to withstand the heat in many parts of the planet. The only question is how long it will take us to get there without some considerable change in our methods of producing energy and food.
I think what was proven is that with higher Co2 the plants would grow better and larger(increased biomass), but without other nutrients added the % of nutrients per the size of plant went down, because the plants size increased more than the nutritional output.
But also more Co2 means less water needed to get them to grow.
i will dig into this... but, greenhouses dont pump Co2 into the greenhouse for nothing. And the earth is greening with the increase in Co2.
Pit Row
Increased air temperatures could definitely increase the rate of the water cycle leading to more precip, but when and where that happens is functionally very important.
Regardless of what fossil fuels do, diversifying and decentralizing energy is likely to reduce other problems down the road not related to weather.
2. there were not many weather stations outside of the US before the early 1900s
3. life exploded on earth when Co2 was like a 10,000 ppm, yes the climate was warmer, but the planet did not burn off because of this extremely high Co2, in fact life thrived more than any other period.
i will address some of this when time permits.
Edit: I don't think more CO2 means less water. Water provides the H for plants to make carbohydrates through photosynthesis.
Humans didn't cause the last ice age,and they didn't cause it to end...and we aren't causing it to warm up now...we are just along for the ride, until we aren't...And the earth will wipe us all out, and then keep on keeping on like its done for billions of years.
I see no point at all in crippling economies, impoverishing societies, and shackling businesses and individuals with regulations in the name of preventing something that has been going on since the beginning of the earth-climate change.
We ought to protect our air, our forests, our water in the name of having a nice place to live...not in a vain effort to save the planet and not at the expense of catastrophic economic consequences.
I don’t think I’ve ever seen anything saying that less water is needed with higher CO2 levels. It would seem like more water would be needed due to increased respiration. Especially with plants out in the atmosphere, where wind and heat increases evapotranspiration by large amounts.
I'm starting to think that when some folks hear the term "Global Warming" they think that presipitation is lessoning globally.
The fact is that due to global warming, precipitation patterns through the last 100 yrs are rapidly changing. Some parts of the world are seeing more precipitation than ever before while other parts are seeing less.
Here's the problem - global climate is heating up which effects rainfall patterns whilst evaporation increases... glaciers melt and sea levels rise. These factors are already affecting the availability of fresh water. More frequent and severe droughts and rising water temperatures are expected to cause a decrease in water quality. It's happening everyday.
George - Your Graph showing USA precipitation ending 2020 may well be spot on but elsewhere, countries are drying up.
We all know Vital has a bunch of amateur gynecologists but for now we could use a legitimately qualified Climatologist to educate and enlighten us.
Land plants are absorbing 17% more carbon dioxide from the atmosphere now than 30 years ago, our research published today shows. Equally extraordinarily, our study also shows that the vegetation is hardly using any extra water to do it, suggesting that global change is causing the world’s plants to grow in a more water-efficient way.
Water is the most precious resource needed for plants to grow, and our research suggests that vegetation is becoming much better at using it in a world in which CO₂ levels continue to rise.
The ratio of carbon uptake to water loss by ecosystems is what we call “water use efficiency”, and it is one of the most important variables when studying these ecosystems.
Our confirmation of a global trend of increasing water use efficiency is a rare piece of good news when it comes to the consequences of global environmental change. It will strengthen plants’ vital role as global carbon sinks, improve food production, and might boost water availability for the well-being of society and the natural world.
another thing, we are also in a solar minimum, which drastically affects normal weather patterns because of how it changes the jet streams.
i can show you many examples of extreme heat and drought from the past if needed.

What is the impact of the Three Gorges Dam?
That biodiversity is threatened as the dam floods some habitats, reduces water flow to others, and alters weather patterns.
