climate change is about people as well as climate. During the last

20 years climate scientists have confirmed that global warming over

the last century is “unequivocal” and that human activities are “very

likely” the major cause (

iPcc 2007).

it is important now to study in

more depth the anthropogenic causes and consequences of climate

change. m

any of these are grounded in demographic change (

o’neill

et al. 2010).
