Such programs as Paideia, Microsociety, and the Coalition of Essential Schools already use project - based and hands - on learning,
embrace alternative assessments, and encourage students to apply their knowledge to real - life problems.
«The Earth's climate system is highly nonlinear: inputs and outputs are not proportional, change is often episodic and abrupt, rather than slow and gradual, and multiple equilibria are the norm... there is a relatively poor understanding of the different types of nonlinearities, how they manifest under various conditions, and whether they reflect a climate system driven by astronomical forcings, by internal feedbacks, or by a combination of both... [We] suggest a robust
alternative to prediction that is based on using integrated
assessments within the framework of vulnerability studies... It is imperative that the Earth's climate system research community
embraces this nonlinear paradigm if we are to move forward in the
assessment of the human influence on climate.»
