She is more wise than all the experts put together.

At least some know the truth. It will unfold over the next couple of decades and of course beyond. I'm sorry for the younger generation who will have to deal with the climate situation that will border on catastrophic.

Some of us were once your age. We panicked as we "ducked and covered". We marched to stop war, promote disarmament, stop police brutality, and protect the world for our future children. We fought in union halls for sexual equality, racial equality, and against hatred. But we are getting older and we need to pass the torch to you, young lady. We who care still panic at the thought of the stupidity that causes pain to the people of our planet.

We were once the younger generation with great ideals and high idealism. The generation than spawned Green Peace and Ban The Bomb. But in real life we didn’t care. We had the opportunity to change things but got sucked into the consumer way of life and hypocritically forgot our message. Why would the current young generation be any different to us?

This new generation of realists will face stiff competition from those of their age group who are brought up as haters & bigots (what they're taught at home). The upside of these realists is they are making their voices heard in the face of adversity. What we need is a real education system, a right being denied them, where truth and acceptance are nurtured instead of shunned. Too many parents are blind to reality and pass along their fears and prejudices. I call this child abuse, and it is truly sad that is so pervasive. There is still some hope as I see more and more people coming to their senses. Getting rid of FOX "news" and its' ilk would be a good starting point.

The fundamental problem for humanity is population expansion - climate change, food and water shortages, plastics, air and other pollution, all go back a rapidly growing number of humans all wanting more of the earths resources. In any other species we would define it as a plague - and like other plagues will be self extinguishing as resources run out.

I love Greta! She's motivated, clever, and on the correct path. I hope to raise my kids with as much concern for the future as she has.

Unfortunately we are acting on the ideals our adults gave us, and they likewise. Cultures change very slowly and almost never without a crisis. The"don't worry be happy" meme is a failure. A former partner was alcoholic and refused to have children because alcoholism was in her family and she didn't want to take a chance and pass on what she had to deal with onto another. That seems to be a rare idea because too many don't care; they just follow their instincts and procreate no matter how difficult things are for them or how bleak the future for future generations. There are also plenty of young people who also won't see the future realistically. I think history and the world experiences have proven great changes don't come without a lot of pain. I really feel for these young people. I also feel tRump is not a problem, he is a symptom of a bigger problem.
My question is just who is it that lacks maturity?

BOOYAH. I find it interesting she used the word "maturity." For sure, intellectually honest people don't ignore evidence, but is it "immature" to do so?

Global warming means dramatic changes in weather patterns, some heatwaves, droughts, storms and floods but none of that will end human life on the planet - though of course large parts of many coastal cities and towns (London, New York etc) will be submerged.
The more probable end of humanity will be a virus, maybe ebola variants, particularly once antibiotics become ineffective.
Then of course there are the ever present possibilities of nuclear war, meteor strike, supervolcano, sunspot energy pulses and too many other routes to devastation,
Moral of all this - don't worry - live well and seek happiness and maybe you will grow old and die with a broad smile on your face.

My advice to older generation is sit down, STFU, and hear them roar. For good or bad, most of the younger are so much smarter than we were.....and many of us are.

Unfortunately it's fear that keeps people from acting. It's fear that causes people to abandon common sense and leads them to follow anyone that tells them it's all a hoax. They prefer to attack the facts and revel in their ignorance as long as it's not their house that's on fire or under water, yet.

Her speech was a home run..spot on

I often think I am happy I am the age I am. I think I will be gone when it really starts hitting the fan. I am glad I have no children

She's right. We need to be raging against the inaction to correct and prevent climate change.

She's right..governments need to put aside corporations well being and start concentrate on the climate change..
