Conversely, any future decision about albedo modification will be judged primarily on questions of risk, and there are many opportunities to conduct research that furthers
basic understanding of the climate system and its human dimensions — without imposing the risks of large - scale deployment — that would better inform societal considerations.
But the issue of ineffective negotiations and lack of in - depth
understanding of the climate system from regions of the world, developing and developed alike, pose a threat to achieving a low temperature increase that is sustainable for livelihoods and in eliminating greenhouse gas emissions.
«The fact that there is a distribution of future climate changes arises not only because of
incomplete understanding of the climate system (e.g. the unknown value of the climate sensitivity, different climate model responses, etc.), but also because of the inherent unpredictability of climate (e.g. unknowable future climate forcings and regional differences in the climate system response to a given forcing because of chaos).
Focus: Long - standing model biases (at least a few of them); Understand how model errors or shortcomings impact projections and predictions; Gain physical
understanding of the climate system through model development.
Given those findings and the rest of the
improved understanding of the climate system, the IPCC projects that if carbon dioxide gas emissions — the primary cause of warming — continue to grow at the recent rate, the world would warm 2oC above 19th - century levels by the middle of this century.
It opposed deployment of albedo - modification techniques, but recommended further research, particularly «multiple - benefit» research that simultaneously advances
basic understanding of the climate system and quantifies the technologies» potential costs, intended and unintended consequences, and risks.
Some surprises in the climate system may be inevitable, but with improved scientific monitoring and a
better understanding of the climate system it could be possible to anticipate abrupt change before it occurs and reduce the potential consequences.
This discrepancy may result from a gap in
our understanding of the climate system or from what we know about the Eocene, said David Evans, the study's lead author and Leverhulme Research Fellow at the University of St Andrews» School of Earth and Environmental Sciences.
These characteristics make the Eocene a good period on which to test
our understanding of the climate system, said Laura Cotton, study co-author and curator of micropaleontology at the Florida Museum of Natural History.
And the evidence of change has mounted as climate records have grown longer, as
our understanding of the climate system has improved and as climate models have become ever more reliable.
Co-author of the study Professor Ian Hall, from the School of Earth and Ocean Sciences, said: «Our results highlight the challenge of basing
our understanding of the climate system on generally short observational records.
So understanding why you would have this brief hiatus in sea - level rise is really key to
our understanding of the climate system and being able to monitor the system,» he said.
It casts doubt upon
our understanding of the climate system and ability to predict future climate changes.»
This is evident from the increasing greenhouse gas concentrations in the atmosphere, positive radiative forcing, observed warming, and
understanding of the climate system.
Although the report does say that achieving a concentration of 400ppm of carbon dioxide by 2100 gives the best chance (80 % according to the Baer research; see footnote 14) of preventing a 2 degree C rise, the Taskforce members are well aware that other emission pathways are possible and that between now and 2100
our understanding of the climate system will improve.
The magnitude looks consistent with
our understanding of the climate system.
