Is all this recent Climate Change stuff pure hysteria?

Have I? I didn't know my posts included sounds.

Also - you're quoting my first post in this thread.



Willful ignorance is bad. Yes, I agree.

However, I think it's vastly understated how those in the West have taken to becoming outraged by topical issues as if it's some kind of hobby. The MeToo movement turned out to be a disgrace for example.
The me too movement isn't science.
Global warming is testable, observable and is the expected, predictable outcome of the measurable increase in atmospheric carbon accumulation.

And how far off into the future are these apocalyptic ramifications expected to become effectual?
Depends what you mean by "apocalyptic". By mid-century, i.e. in your lifetime, there are expected to be major effects.

But we are already seeing effects today. Here is an article on the insurance industry, which is having to adapt to the increased level of payouts for weather-related damage and is trying to plan how to cope in the future. Insurance in a Climate of Change

What's rather sad and pathetic is how many people actually believe that fossil fuel lobbyists and their puppet politicians are more honest and trustworthy than the international scientific community, as if it's the latter who hide a dishonest agenda and who have something to gain by deceiving the public.

There are basically two major uncertainties in projecting the future of climate change. The first one is what we, the human race do, and how fast we reduce our emissions or if we continue on a "business-as-usual" path.

The second is the sensitivity of global temperatures to changes in the concentration of greenhouse gases in the atmosphere. This is a major source of uncertainty in climate modelling, but the biggest concern is that we introduce "positive" feedback effects which take the course of climate change out of human control. One basic example is that as the polar ice caps melt, that reduce the amount of the sun's energy that is reflect out in to space and is instead absorbed by the earth's surface. So the world's surface absorbs more solar radiation and hence there is more "energy" in the climate system, raising global temperatures.

Timelines for this are therefore based on probabilities, and predictions don't extend beyond 2100. My understanding is that scientists are ruling out the lower ranges of these projections, because we aren't reducing our emissions fast enough and the data suggests a high sensitivity to greenhouse gas emissions, so projections are now anticipating increases in the higher temperature ranges with more serious consequences for the future of the planet and humanity.

(edit: In laymen's terms, we should go beyond the 2 degree threshold considered "safe", admittedly dubiously by the middle of the century and hit maybe 3 or 4 degrees by 2100)

In your opinion, what defines "qualified opinions" in this context?

Is it any person who understands what climate change is, or does it strictly refer to those who hold a PHD in ecology? Because if it is the latter, I think you are wading into dangerous territory.
Not playing this game, pal.

Science has a reputation for a reason.

It's already happening, and the effects are accelerating. Have you been reading the news?
The academics who are employed by corporate and political entities to assist them with their agendas.
So you think this is a conspiracy; that all these millions of unrelated researchers in dozens of different disciplines are all in cahoots? With whom? To whose benefit?

I agree that there is an element of conspiracy, but the "corporate and political entities" are paying off the climate deniers, not the unaffiliated scientists reporting the effects within their own areas of study. The conspiracy is in the denial.

I can remember being a young boy in primary school learning, in great scientific detail, about what climate change is, why it is happening and the role that human beings play in causing it.

This was something like circa 1998.

Since then, there have been modest yet genuine attempts to rectify the issue through carbon emissions schemes, changes to the materials corporations use, et al. It's modest, but progress has been made.

On the other hand, apocalyptic visions for the outcome of our impact of the world and a complete exaggeration of how we are all in imminent danger seems to have exploded into the forefront of the international media this year.

Personally, I think the biggest problem humans face today is that too many people in the West get off on being outraged.
If you learned about this in primary school, you did not learn about it "in great scientific detail". Have you made any attempt to learn more subsequently?
