We can keep global warming below the danger-threshold of 2 degrees C, even below 1.5 degrees of warming. But this is only possible if we make deeper and faster emissions cuts and all governments introduce ambitious policies, backed by strong ...
In business-as-usual scenarios, consumption grows by 1.6 to 3 per cent per year. Ambitious mitigation would reduce this growth by only around 0.06 percentage points a year. This estimate does not take into account economic co-benefits of taki...
Scientists predict that more than half of the 103 ski resorts in the Northeast are at risk of not being able to maintain a 100-day season by 2039. >> Team Climate
Over the last decade, the ski industry has lost $1.07 billion in aggregated revenue between low and high snow fall years. The corresponding employment impact is a loss of between 13,000 to 27,000 jobs. >> Team Climate
In the Northeast, the length of the snow season will be cut in half. >>Intergovernmental Panel on Climate Change
In the West, snow depths could decline by 25 to 100 percent. >>Intergovernmental Panel on Climate Change
Warmer winters will lead to shifts in precipitation from snow to rain, a shorter snow season, and decrease snow cover area. >>Intergovernmental Panel on Climate Change
Winter temperatures are projected to rise 4 to 10 degrees Fahrenheit before the end of the century. >>Intergovernmental Panel on Climate Change
Snow cover in the Northern Hemisphere has decreased in March and April by 1.6% per decade and in June by 11.7% per decade for the last thirty years. >>Intergovernmental Panel on Climate Change
In the Northern Hemisphere, the last thirty years were warmer than any other of the last 1,400 years. >>Intergovernmental Panel on Climate Change
Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, sea level has rise...
In 2013, daily average CO2 measurements exceeded 400ppm for the first time in at least 800,000 years. >> Climate Central
