<p>El Niño is a climate event without equal. It affects almost every
region of the globe, causing droughts in some areas, and floods,
hurricanes and typhoons in others. Famine, disease, disruption to
infrastructure and transport follow in their wake, causing
humanitarian as well as economical problems. Understanding El Niño, and
ideally predicting what it will do in a given year, is crucial — and
here maths can go a long way.</p><p><a href="https://plus.maths.org/content/elninowhatearthwillhappennext" target="_blank">read more</a></p>

<p>A team of researchers at the University of New South Wales has delivered dire news for polar
ecosystems, predicting that in some regions biodiversity may be
reduced by as much as a third within decades. This is a result of
global warming: as the poles warm up, sea ice will melt earlier,
allowing a lot more sunlight to reach the sea bed. The team's study
predicts that this can have a significant effect on the creatures
that live there. Invertebrates that are adapted to live in dark
conditions will be pushed out and replaced by algae that thrive on
light.<p><a href="https://plus.maths.org/content/tipping" target="_blank">read more</a></p>

The concept became known as <em>Laplace's demon</em> and was a thought experiment which sought to clearly explain the existence of uncertainty.
