UN Panel: Fossil Fuels Must Be Phased Out by 2100

The Intergovernmental Panel on Climate Change, a UN-backed panel of experts, has concluded that the unrestricted use of fossil fuels without carbon capture and storage (CCS) technology should be phased out by 2100 if we are to avoid dangerous climate change. While the costs of phasing out fossil fuel use and transitioning to renewable energy sources will undoubtedly be steep, failing to make the necessary changes will be more costly in the long run.

The problem is more than just greed. Many still think it's some kind of a hoax.

HAHAHAHAHAHA! Good luck with that one! "Good, after my life expectancy. Someone will get right on that."

Make every post as if it was the first one in the thread.

The changes required are extremely drastic. It'll take a lot of time to enforce them. Personally, I don't believe the world has the political will to do what is required until it's too late.

I can't believe there are still people who are sceptical of climate change. I think most countries will wait until the last minute to make changes. Politicians worry about now & the next election Shame on you
Mind you, we're voters. We've got to make our voices heard at election time. Think

We, who think were aware of this problem some 35 to 40 years ago but we have been fought by the corrupt and extremely greedy corporations and politicians, and are still being "stalled" by them. The Koch brothers are an excellent example of what is wrong with this country (America) and the only real answers lies in a revolution, because they and their types will never change until they are dead...

If we teach young children and growing teenagers how to stand up to stale corrupt power, and the military that supports it, then positive changes can happen.

From the magazine Nature. It's a long article, and I won't put all of it here, and there are many more, if anyone is interested in reading them.

No one knows for certain, one way or the other, and to claim anyone can, is not possible, especially the politicians at the UN.


CLIMATE CHANGE

COMMENTARY:
Overestimated global warming over the past 20 years
John C. Fyfe, Nathan P. Gillett and Francis W. Zwiers
Recent observed global warming is significantly less than that simulated by climate models. This difference might be explained by some combination of errors in external forcing, model response and internal climate variability.
Global mean surface temperature over the past 20 years (1993–2012) rose at a rate of 0.14 ± 0.06 °C per decade (95% confidence interval)1.

This rate of warming is significantly slower than that simulated by the climate models participating in Phase 5 of the Coupled Model Intercomparison
Project (CMIP5). To illustrate this, we considered trends in global mean surface temperature computed from 117 simulations of the climate by 37 CMIP5 models (see Supplementary Information). These models generally simulate natural variability — including that associated with the El Niño–Southern Oscillation and explosive volcanic eruptions — as well as estimate the combined response of climate to changes in greenhouse gas concentrations, aerosol abundance (of sulphate, black carbon and organic carbon, for example), ozone concentrations (tropospheric and stratospheric), land use (for example, deforestation) and solar variability. By averaging simulated temperatures only at locations where corresponding observations exist, we find an average simulated rise in global mean surface temperature of 0.30 ± 0.02 °C per decade (using 95% confidence intervals on the model average). The observed rate of warming given above is less than half of this simulated rate, and only a few simulations provide warming trends within the range of observational uncertainty (Fig. 1a).

The inconsistency between observed and simulated global warming is even more striking for temperature trends computed over the past fifteen years (1998–2012).
For this period, the observed trend of 0.05 ± 0.08 °C per decade is more than four times smaller than the average simulated trend of 0.21 ± 0.03 °C per decade (Fig. 1b). It is worth noting that the observed trend over this period — not significantly different from zero — suggests a temporary ‘hiatus’ in global warming 2–4. The divergence between observed and CMIP5-simulated global warming begins in the early 1990s, as can be seen when comparing observed and simulated running trends from 1970–2012 (Fig. 2a and 2b for 20-year and 15-year running trends, respectively).

The evidence, therefore, indicates that the current generation of climate models (when run as a group, with the CMIP5
prescribed forcings) do not reproduce the observed global warming over the
past 20 years, or the slowdown in global warming over the past fifteen years. This interpretation is supported by statistical tests of the null hypothesis that the observed and model mean trends are equal, assuming that either: (1) the models are exchangeable with each other (that is, the ‘truth plus error’ view); or (2) the models are exchangeable with each other and with the observations (see Supplementary observed and simulated 20-year trends have pvalues (Supplementary Information) that drop to close to zero by 1993–2012
under assumption (1) and to 0.04 under assumption (2) (Fig. 2c). Here we note
that the smaller the pvalue is, the stronger the evidence against the null hypothesis. On this basis, the rarity of the 1993–2012 trend difference under assumption (1) is obvious. Under assumption (2), this implies that such an inconsistency is only expected to occur by chance once in 500 years
