Climate change (cid:862)a (cid:272)ha(cid:374)ge of (cid:272)li(cid:373)ate (cid:449)hi(cid:272)h is attri(cid:271)uted dire(cid:272)tly or i(cid:374)dire(cid:272)tly to hu(cid:373)a(cid:374) a(cid:272)ti(cid:448)ity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over (cid:272)o(cid:373)para(cid:271)le ti(cid:373)e periods. (cid:863) International treaty that set up framework to combat climate change, 92: objective = to stabilise greenhouse gas concentrations. In a sustainable way: do this at a rate that allows ecosystem to adapt naturally, does not threaten food production, enable sustainable economic development. Ippc: established by the un, environmental program and world meteorological. International panel on climate change organisation, 88: 157 member states, reviews and assesses studies on climate change to summarise them, 5 working groups, physical science. The greenhouse effect: natural is required to warm the earth"s surface and make it habitable, anthropogenic, causes earth to overheat due to oversupply of greenhouse gas, ghs"s trap extra heat, causing a rise in the earth"s temperature.
