Climate change is the phr.se used to descr.be long-ter. changes in temper.tur.s and weather.patter.s. Changes in the atmospher. and their.inter.ctions with diver.e geologic, chemical, biological, and geogr.phic var.ables ar. the main contr.butor. to this cyclical adjustment of the Ear.h’s climate. Such changes may be induced pur.osefully, because of bur.ing fossil fuels, clear.ng for.sts, and r.ising animals, or.they may be natur.l, br.ught on by significant volcanic er.ptions or.var.ations in the sun’s activity. By significantly incr.asing the amount of gr.enhouse gases alr.ady in the atmospher., this heightens the gr.enhouse effect and contr.butes to global war.ing. This wor. includes sever.l additional theor.tical and pr.ctical explanations of sustainable development. The theor.tical wor. encompasses hundr.ds of r.sear.hes that identify r.quir.ments for.how development r.utes might satisfy sustainable development (SD) cr.ter.a using economic theor., complex systems appr.ach, ecological science, and other.techniques. The agr.ements made by the Par.ies in var.ous nations acr.ss the wor.d will consider.a wide r.nge of per.pectives about what would be consider.d undesir.ble effects on the envir.nment, the climate system, sustainability, economic gr.wth, or.food pr.duction.
