Still, a great portion of the «summary for policymakers» deals with the recent temperature rise, and it concludes that it's «likely» that there is a human contribution to the observed
trend (by which I assume CO2
emissions are especially
understood, even more so considered the negative forcings mentioned).
I would have said it is transparently obvious that ice volume is a better measure than ice area, if you want to
understand long - term
trend and the impact of human
emissions — though it's great to have both measures.
My
understanding is that at this point we can control the situation somewhat; reducing our
emissions should eventually reduce or stop the warming
trend.
Monitor
trends in energy use and CO2
emissions: follow the evolution of 50 global energy efficiency indicators to better
understand policies» impact.
They also limit our
understanding of how anthropogenic
emissions will affect future warming
trends.
Even worse, the paper's authors concluded «the new data call into question our
understanding of observed stratospheric temperature
trends and our ability to test simulations of the stratospheric response to
emissions of greenhouse gases and ozone - depleting substances.»
Ultimately, the latest scientific
understanding of climate change allied with current
emission trends and a commitment to «limiting average global temperature increases to below 4C above pre-industrial levels», demands a radical reframing of both the climate change agenda, and the economic characterization of contemporary society.
Finally, the researchers examined collections of model simulations with and without human
emissions factored in to
understand to what degree human
emissions were responsible for a given impact, by comparing these simulations against observed
trends.
You clearly don't
understand my statement «the
trend in temp... is not inconsistent with the
trend in predicted CO2 forcings» saying in response: «The
trend... is consistent with * actual
emissions *.
For example, they pointed to additional temperature data gathered in the last few years, which have been substantially warmer than any similar string of years in many centuries; to improvements in computer models designed to project future
trends; and to better
understanding of the influence of other climate - influencing
emissions, like particles of sulfates that can cool the earth by reflecting sunlight back into space.
While this
trend is not evident in observational data to date, our research highlights the immediate importance of
understanding how climate variability and disturbance affects savanna dynamics if landscapes in this region are to be used as enhanced carbon sinks in
emission offset schemes.
