Howdy ,

First, I would like to state that we (humanity?) do not control Global Change nor Climate Change. We do not even control human demography, one of the main triggers of Global Change. There are many cultural, religeous and economic bottlenecks to overcome in a short delay, to get a grip on Global Human demography. Humanity has no lack of technological know-how, but for example the president of the US prefers old technologies to be applied in his country as opposed to durable and hence advanced technologies. Hence, I am rather pessimistic when we are looking for pathways of how to get control on Global Change, Climate Change, declining Biodiversity, and hence all the impacts on the Earth's biomes and resources.

I figger that only hope but especially (a better) understanding of system Earth can lead to a new human generation that will not accept the future plotted out by an old human generation of which the (rich and mostly corrupt) decision makers plot a route of 'laisser faire' to the end of humanity as we know it now.

Just imagine how many folks in the global population of this planet would stick to an offspring of two children, instead of the more, the better. Any demograph will tell you that an offspring of two kids, will stabilize human population and even on the long-term, will slowly decline it.

The Earth cannot be raped indefinitely, to feed an ever increasing number of hungry mouths. Even potable water is a problem for almost half of the world population. Incroyable mais vrai, water wars are the result. In general wars for important resources are legio.

Hence, what in fact do we control? Not so much according to me.

I do not believe it, its consequences are clearly estimated if the patterns of its mathematical modeling are maintained, the problem does not lie in the estimates of the damages, but rather, in taking control of the triggering elements.

We may hope that the continuing uncertainties in climate projection (so called the patterns of mathematical modeling in climate sciences) will be narrowed in future. But I wonder, with the massive information flow with uncertainty in it which is coming in the way of analyzer and decision makers and others must not make it more uncertain.

I think, need of how to overcome such difficulties will arise soon in coming future.

Cheers!

I agree with previous opinions!

If we continue pumping more and more carbon dioxide into the atmosphere we are bougrnd to reach +1.5 C and later +2.0 C. Do you know what the consequences of that will be? Is not the future uncertain.

One thing is certain; the melting of the Greenland ice sheet will accelerate and Florida, Holland, and Bangladesh will slip below the waves.

Alastair Bain McDonald,

Thank you for the valuable remarks.

In terse, I can tell, the consequences would be very devastating in both the levels.

I hope associated uncertainties in climate projection based on climate modelling will not make the future unlike we want. I am not sure how accurate the climate models (with existing uncertainties for example- the snow-albedo feedback etc…) are in simulating the ice sheet, considering the carbon emission rate at present day value. Lot is work is still required in the line.

And, I hope that uncertainties in projection should not lead uncertainties in analyzing and decision making. Besides, hope it should not make the whole issue difficult to handle and creates problem in implementation of measures to curb carbon.

Cheers!

We know very well that many of the issues of global concern has become a subject of political bickering. Particularly the theory of climate change and global warming, where it has become subject to geopolitical ploys of some superpowers.

But it is true, the Temperature rates are constantly rising.

I will attach a graph showing that

Yes, I agree with you. Nice information. Hope the constructive awareness through emerging knowledge will narrow the existing differences in the implementation strategies.

I will absolutely grant that their is an incredible amount of uncertainty when it comes to climate change. However, I would also point out that even our boldest estimates of how impactful climate change "will be" and how quickly those changes will manifest have consistently fallen short of reality. Things always seem to be worse than we hoped 5-10 years ago.

I agree with Ian Rayan that realties are more grim than projected once and foregoing argument of economic, social, cultural, technological & religious bottlenecks to this issue. The need of the hour is awakened policy makers with firm implementation. Hope this need becomes reality in near future.

Frank Veroustraete,

Thanks for placing your valuable points. With time, many ongoing capacities controlling or handling (especially decision making) the issues will undergo transformation so probably not sure into which side it will turn. Uncertain to predict; in the line, I feel.

Cheers!

Thanks, Ian Ryan and Swaroop for making a point.

I can sense the amount of uncertainties lying in handling the GB issues.

To me it looks that we are heading TOWARDS an uncertainties in controlling the global warming (GB) issues and its impacts.

But I understand there will be different thoughts on the line of discussion.

Would be happy to know different school of thinking or views “Are we truly heading TOWARDS an uncertainties in controlling the global warming (GB) issues and its impacts?”

There are many possibilities which favor the idea and many which un favor the idea. Seems, it is going to be an interesting discussion!

What you say?

You are absolutely right. Unfortunately, we will witness continuing uncertainties in climate changes scenarios and this will lead to the complication in the predictions and results inferences. We know very well that the main industrialized countries ,specially USA and China are the main contributors in the global warming gas emissions.

We have to reduce our pollution productions and we r the person's for climate change so do some regulations and laws to prevent pollution

I wonder uncertainties mentioned may not lead to uncertainty in the global economic development. The below mentioned recent report may manifest it. You may read it..

According to new analysis (by Oxford Economists: hotter World Will Be Poorer and More Unequal), 3°C of warming by 2100 has the potential to reduce the level of global GDP in 2100 by 21%. More surprisingly, it identified that a country whose average annual temperatures today are cooler than 15° C, including those in North America and Europe, stand to benefit slightly in the short term from rising temperatures. Tropical and subtropical countries whose average temperatures are already warmer than 15° C today, including the entire global South, face catastrophic economic degradation. In short, hotter World Will Be Poorer and More Unequal. I hope such findings will not create unwanted trouble to Paris climate agreement' accomplishment. Because recent finding may create political differences in accepting the Paris climate agreement. For example, countries which are getting benefited by rising temperatures may not encourage immediate efforts to impede rising temperature by curbing CO2 emission, if they choose to be prejudiced. And may consider to be away from the Paris climate agreement.
