What is the biggest constraint on reducing climate uncertainties?
Many uncertainties about how the planet will react to a future anthropogenic warming still exist. It is of critical importance that we reduce these uncertainties as much as possible and as fast as possible. So what do you believe is holding us back the most?
Is it lack of sufficient computing power? Lack of observational data? Lack of brain power (e.g. fundamental theory)? Something else?
Phrased differently: If you had million to put towards the sole goal of reducing the uncertainty of one specific climate variable, how would you spend it? And which specific uncertainty would your investment aim to tackle?
Read MoreWhat are some genuine uncertainties regarding climate change?
It’s widely accepted that human activities are impacting upon the climate and this is supported by reconstructed, observational and empirical evidence. Within the climatic systems there are many inherent complexities and uncertainties. There are known inconsistencies and apparent contradictions and of course, there is much that we don’t fully understand.
What do you consider to be the uncertainties regarding climate change, what are the inconsistencies and in which specific areas do you feel a greater comprehension would be of significant benefit?
Read Morehow is it possible for climate models to be as reliable as the models used in other branches of science?
In other branches of science, through observation and trial and error one can refine and reduce the uncertainties. In climate science it is acknowledged that the observations of our climate system are inadequate. Trenberth called it a "travesty".
He thinks it is a travesty that we lack proper observations, not that he thinks that the models are inadequate.
How do we play our hand in dealing with global climate change?
Due to uncertainties in projected climate changes and in how systems respond to those changes, adaptation options offer varying degrees of uncertainty,or risk if you will.
No-regret: Actions that make sense or are worthwhile regardless of additional or exacerbated impacts from climate change.
Opportunity: Actions that capitalize on observed or projected climatic changes. The proactive farmer who switches to a more adaptative crop, for example.
“Win-win”: Actions that provide adaptation benefits and meet other social, environmental, or economic objectives.
Low-regret: Measures with relatively low costs for which benefits under climate change scenarios are high, like factoring climate change into public land management policies.

I need help with my project please help.
What is the greenhouse effect?
List three greenhouse gases.
List three facts about global warming.
List three uncertainties about global warming.
What’s your opinion? Is global warming a real threat or are there more important environmental issues to resolve?
Please don’t be silly.
