Why do so many people pay so much attention to the end of the world that a girl preaches and they don't pay attention to what the Nobel prizes say, about the Climate Change?
Weather changes all the time. It is highly dynamic in nature. The average pattern of weather, called climate, usually remains uniform for centuries if it is left to itself. However, the Earth is not being left alone. People are taking multi-dimensional actions that are gradually changing the morphology, physiology, and anatomy of the planet Earth and its climate in large scale. The single human activity that is most likely to have a large impact on the climate is the burning of "fossil fuels" such as coal, oil and natural gas. These fuels contain carbon. Burning them liberates carbon dioxide gas in the atmosphere. Since the early 1800s, when people started burning large amounts of coal and oil, the amount of carbon dioxide in the earth's atmosphere has increased by nearly 30%, and average global temperature appears to have risen between 1° and 2°F. This increment of temperature is keenly related to the basic property of the gas. Carbon dioxide gas traps solar heat in the atmosphere, partly in the same way as glass traps solar heat in a sunroom or a greenhouse. For this reason, carbon dioxide is sometimes called a "greenhouse gas." As more carbon dioxide is added to the atmosphere, solar heat faces more trouble in getting out. The result is that, if everything else remains unchanged, the average temperature of the atmosphere would increase. With increased rate of industrialization and urbanization the demand for fossil fuel based energy has hiked up. As people burn more fossil fuels for energy they add more carbon dioxide to the atmosphere. This creates a blanket of carbon dioxide over the Earth’s surface, which allows only the short waves of the sun to penetrate the Earth’s atmosphere, but prevents the long wave radiations (emitted from the Earth’s surface) to get out. If this activity continues for a long period of time, the average temperature of the atmosphere will almost certainly rise. This is commonly referred to as global warming. Global warming is thus the increase in the average temperature of the Earth’s near-surface air and oceans in recent decades and its projected continuation. The term “global warming” is a sub-set of the universal set climate change, which also encompasses another sub-set called “global cooling.” The United Nations Framework Convention on Climate Change (UNFCCC) uses the term “climate change” for human-induced changes and “climate variability” for other changes. Climate change is therefore any long-term significant change in the “average weather” that a given region experiences and involves changes in the variability or average state of the atmosphere over durations ranging from decades to millions of years. The roots of these changes can be related to several dynamic processes on Earth, external forces including variations in sunlight intensity, and more recently by human activities.

Well explained professor Mitra!
It is not "our" fault. It is intentional, part of the silence campaign by the Oil Business to hide the side effects of pollution of the air. Because the gas emissions are not visible nobody noticed them. Now, we all have to pay the price for hiding pollution from the public.
The "girl" is speaking the truth, much better than Nobel winners. She is right to be mad, her whole generation has been tricked and will suffer.
Human greed, population explosion, ignorance and profit oriented capitalism could be considered as the main factors for climate change.
These comments are nothing but echoes of the politically correct propaganda, one must say considering the intensity and barrage of this "information". Alternative information is silenced.
I completely agree with the Russian president Putin in this case:
Putin:
"I may disappoint you but I don't share the common excitement about the speech by Greta Thunberg.
"No one has explained to Greta that the modern world is complex and different and ... people in Africa or in many Asian countries want to live at the same wealth level as in Sweden."
"But when someone is using children and teenagers in personal interests, it only deserves to be condemned.
"I'm sure that Greta is a kind and very sincere girl. But adults must do everything not to bring teenagers and children into some extreme situations."
The problem in the USA and in other industrial countries is that we avoid acknowledging the huge cost of making our historically developed cultural life-styles affordable in a future economy. The total cost to the earth of an automobile is not paid for in the pricefrom the dealership or the price of the gasoline or electricity used. The taxes applied do not suffice. We need to shift to an economy that pays for all the real costs and unfortunately many current businesses would go bankrupt in making that shift. Our current government does not have a plan to deal with this problem on a national or international basis. Our government's current plan is to simply deny that global warming exists or is a real problem. Greta is a voice trying to make citizens of the world acknowledge the problem and to at least devise a workable plan. Both Alexander Kolker and Putin's opinions are currently held by ostriches with their heads in the sand.

It is pretty clear from the IPCC reports that human caused climate change is a real problem: https://www.ipcc.ch/sr15/chapter/spm/
Regarding Greta Thunberg, she has said: “I don’t want you to listen to me, I want you to listen to the scientists.”
Good advice in my view.
There are multiple references are being made on the IPCC reports. However it looks like that some of these reports published in various years contradict to each other. Some reports, such as the one referenced in the above post, state that humans caused the climate change due to one factor-producing excessive level of CO2.
However other reports presented by IPCC earlier state the following:
(see https://archive.ipcc.ch/ipccreports/tar/wg1/504.htm)
"The climate system is particularly challenging since it is known that components in the system are inherently chaotic; there are feedbacks that could potentially switch sign, and there are central processes that affect the system in a complicated, non-linear manner. These complex, chaotic, non-linear dynamics are an inherent aspect of the climate system. As the IPCC WGI Second Assessment Report (IPCC, 1996) (hereafter SAR) has previously noted, future unexpected, large and rapid climate system changes (as have occurred in the past) are, by their nature, difficult to predict. This implies that future climate changes may also involve surprises. …Observations, paleoclimatic data, and models suggest that such thresholds exist and that transitions have occurred in the past … Comprehensive climate models in conjunction with sustained observational systems, ... are the only tool to decide whether the evolving climate system is approaching such thresholds." and "We simply do not fully understand the causes of climate drift in coupled models (see Chapter 8, Section 8.4.2)." This quotation is the last line in https://archive.ipcc.ch/ipccreports/tar/wg1/504.htm
In summary -bullet point #6 in the link: https://archive.ipcc.ch/ipccreports/tar/wg1/501.htm
"The climate system is a coupled non-linear chaotic system, and therefore the reliable long-term prediction of future climate states is not possible."
Therefore, on one hand the IPCC promotes the idea of excessive amount of CO2 as the main reason for climate change but, on the other hand, it follows from other IPCC reports that attributing all climate change to only one factor-human generated CO2-is NOT substantiated because the long-term prediction of climate states is not posible.

"In future more comprehensive models, human activities need to begin to interact with the dynamics of physical, chemical, and biological sub-systems through a diverse set of contributing activities, feedbacks, and responses." See the last bullet point in

Climate Change Is Not Our Fault
The NPR article is headed “It is not our fault” but the text acknowledges that the use of fossil fuels has resulted in climate change. The many benefits arising from fossils are recognised and the author considers the climate impact a regrettable consequence of this progress.
Fossil fuels have advanced society technologically and improved living and health standards for the majority of the world’s population. At the same time, the world’s population has exploded placing pressure on food supplies and natural resources. As the climate gets hotter food production may slow down and as regions become less hospitable forced migration will lead to conflict. An apocalypse is on the way unless we take action on climate change.
Yes, it is our fault and we need to take action to precipitate change. Politicians balance many competing issues in formulating their policies. We all need to make it clear that we want governments to affect change and if they are non-responsive we will vote for someone else who will. There are potential solutions available to slow down and possibly reverse global warming: what is needed is the will to implement them.
