The World Climate Research Programme s Open Science Conference taking place this week aims to increase understanding of the naturally occurring variability and human
influenced change in our climate system and its impact on our society and ecosystems.
Abrupt climate change is defined as a large scale
change in the climate system which takes place over a few decades or less and is anticipated to persist for at least a few decades, and causes substantial disruption in human and natural systems.
Dramatic and unprecedented warming in the Arctic is driving sea level rise, affecting weather patterns around the world and may trigger even
more changes in the climate system.
If you are looking to
see changes in the climate system, then look at climate data, not loss data (climate data can however be used to test the fidelity of loss normalization methodologies)
In episode 53 of Forecast, Mike talks with Julia Pongratz from the Max Planck Institute for Meteorology about the role of land cover and land
use change in the climate system.
The flap about sea level is a reminder that I.P.C.C. doesn't work well on topics that are outside the normal bounds of consensus science — yet those «extremes» are key to understanding the tails of the distributions, especially those that relate to possible
catastrophic changes in climate systems.
It's the long - term range (30 - plus year cycles) that scientists look at to determine
real changes in the climate system, and the changes scientists see are unmistakable.
The study, appearing this week in the Proceedings of the National Academy of Sciences, also ties the shifting monsoon to changes in Earth's orbit and other
periodic changes in the climate system.
Several studies have found that some models were not getting the timing right of the kind of short - term
natural changes in the climate system that can happen over the course of a decade or so, such as volcanic eruptions that have a cooling effect or El Niño weather patterns that have a warming effect.
N (1) Natural mechanisms play well more than a negligible role (as claimed by the IPCC) in the
net changes in the climate system, which includes temperature variations, precipitation patterns, weather events, etc., and the influence of increased CO2 concentrations on climatic changes are less pronounced than currently imagined.

Between Changes in the Climate System and Biogeochemistry.
The World Meteorological Organisation (WMO) says: «Dramatic and unprecedented warming in the Arctic is driving sea level rise, affecting weather patterns around the world and may trigger even
more changes in the climate system.
I'd venture to say that even if we stopped producing all forms of GHG emissions TOMORROW, we'd still experience
the changes in the climate system that will determine how we live our lives in the future.
Most will eventually be faced with the reality that
changes in the climate system are impacting the programs they manage.
This is a very good case for studying how quickly the Earth's temperature responds to
changes in the climate system.
Press Trust of India: Continuous emissions of greenhouse gases will cause further warming and
changes in the climate system, R K Pachauri, the head of the UN body of climate change has said and called for effective risk management to mitigate global warming.
