Scientists have found that winters warmer than -8C could lead to water shortages. River basins around the world that once regularly experienced snow are now increasingly witnessing their snowpack shrinking.
In their pursuit of improved water conservation strategies along the Colorado River, scientists are now examining the influence of mountainous regions on how El Niño and La Niña events affect precipitation in the western part of North America.
You have probably noticed when you go for a walk in the winter that everything is much calmer or quieter and this is largely due to the fact that many birds hide underground, migrate or simply change colour to survive the cold temperatures.
