Well... critics have a point when they say that temperature rise has halted for about 15 years.
But imo it's too soon to tell if this is really statistically significant compared to the longer (fairly reliable) data of the past 50 years, or the more historical data of 150 years in the past.
Imho it'll take a while before things really become noticeable. So far there was an increase of less than 1 degree celcius (on average), that's hard to notice. In 50 years time the statistics will be more significant and maybe the effects will become more noticeable than right now.
However, what I don't get about them, is that the deniers completely ignore evidence from the ancient past, and they ignore the sheer quantities of carbon dioxide that are produced every year. I mean... it's mind-boggling and hard to understand, but if you just look at the numbers, it's really a lot... and they don't want to do an extrapolation of carbon build-up in the future and what that means for our future.
And their excuse is ... you cannot extrapolate because we don't know what's going on yet. Well... we do have a lot of numbers on it already and it's crystal clear to me that we're heading for a disaster. They say the numbers aren't reliable... well, that's always the case, we work with the knowledge we have at the moment.
Or maybe they're bad at math. I don't know.
Or maybe they cannot imagine that nature is pretty slow at storing carbon. And that the coals we are digging up, which took nature millions of years to accumulate, are now injected back into the atmosphere at a very, very high rate. Far higher than any time in the past. It is hard to understanding how incredibly slow such a geological process is... it works at an enormous scale, sure (at a scale of the whole earth), but actually absorbing and burying hundreds of billions of tons of carbon... well that just takes a very long time.
But reality is, some people only wake up when they cannot deny things anymore. That is human nature. You see it in politics. In corporations... people who are responsible are often in complete denial about problems, and only admit them at the last moment when denying is no longer possible. And people who are not responsible, they don't care, they have no responsibility and do not need to think about things. So what do they do ... the thing that is easiest: do nothing as long as possible.
But well... it's also pretty clear to me that it'll take decades, maybe even 100 years, before things are going to get a lot hotter, maybe by that time people will take action. I would prefer if they did that now. It's a shame generations will face the additional task of having to clean up the extra mess that we've made in those 100 years and they will have 100 years less time to change the economy.
Deniers sometimes also gamble that by that time, the problem has already disappeared by itself because of cheap solar panels, or because of nuclear fusion. But it's a long stretch to say that those technologies will be much cheapier by that time than they are now... that's a big gamble.
For example, the cost of a solar panel comes from the cost of its raw materials and the machinery and labor that's required to build them... why would those become cheaper?
For example nuclear fusion... it's not guaranteed that nuclear fusion will ever work. If it works, maybe the installations that are required will be so costly, that it'll be an extremely expensive source of energy. Maybe it'll take more than 100 years before that technology has matured, maybe even longer.
Will future generations have the same (or better) capacity to deal with the problem as we have? If temperatures rise in the next 100 years, that will affect agriculture, which will require a costly relocation of plants. If storms and droughts become more extreme over the next 100 years, more resources will be needed to repair for damages and crop losses.
If there are 2x more people at that time than there are now, will that mean that it'll be easier to tackle the climate warming, or will it be harder? Maybe it'll be harder, because so many people will require at least 2x more resources than we use now. Resources will become more expensive, meaning that solar panels will become more expensive. Maybe poverty becomes so widespread, that there is simply no money or interest left to handle other problems.
Oh but wait... I said I'd stop... I'd better stop posting.
