"The past century of human-induced warming has increased rainfall variability
over 75% of the Earth’s land area – particularly over Australia, Europe and
eastern North America, new research shows.
The findings, by Chinese researchers and the UK Met Office, were published
overnight in the journal
Science. They provide the first systematic
observational evidence that climate change is making global rainfall patterns
more volatile.
Climate models had predicted this variability would worsen under climate
change. But these new findings show rainfall variability has already worsened
over the past 100 years – especially in Australia.
Past studies of the observational record either focused on long-term average
rain, which is not systematically changing globally, or rainfall extremes where
changes are hard to measure accurately. This study looks solely at variability,
which refers to uneven timing and amount of rainfall.
The results are consistent with previous research, including ours. This means
dry periods are drier than in the past, and rainy periods are wetter.
Alarmingly, the problem will worsen as global warming continues. This raises
the risk of droughts and floods – a pertinent issue for Australia."
