Climate change is a major topic of concern today,
scientifically, socially, and politically. It will
undoubtedly continue to be so for the foreseeable
future, as predicted changes in global temperatures,
rainfall, and sea level take place, and as human society
adapts to these changes.
In this remarkable new
work, Jan Zalasiewicz and Mark Williams demonstrate how
the Earth's climate has continuously altered over its
4.5 billion-year history. The story can be read from
clues preserved in the Earth's strata - the evidence is
abundant, though always incomplete, and also often
baffling, puzzling, infuriating, tantalizing, seemingly
contradictory. Geologists, though, are becoming ever
more ingenious at interrogating this evidence, and the
story of the Earth's climate is now being reconstructed
in ever-greater detail - maybe even providing us with
clues to the future of contemporary climate change.
The history is dramatic and often abrupt.
Changes in global and regional climate range from
bitterly cold to sweltering hot, from arid to humid, and
they have impacted hugely upon the planet's evolving
animal and plant communities, and upon its physical
landscapes of the Earth. And yet, through all of this,
the Earth has remained consistently habitable for life
for over three billion years - in stark contrast to its
planetary neighbours. Not too hot, not too cold; not too
dry, not too wet, it is aptly known as 'the Goldilocks
planet'.
