Atmospheric Blocking Increase
Climate change is thought to increase the frequency of large scale atmospheric pressure patterns with little or no movement—referred to as atmospheric blocking—by increasing changes in planetary wave activity that causes the atmospheric equivalent of a traffic jam.[1] Studies have begun to identify an anthropogenic component in recent blocking events that drove sustained extreme weather, including the 2003 European heatwave, the 2010 Moscow wildfires, the 2011 Texas and Oklahoma drought, the 2011-2016 California drought, and the 2018 Northern Hemisphere heat wave.[2][3]

Earth Systems Signals
Global warming is causing widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere.
Heat Signals
The Earth is getting hotter due to human activities that release heat-trapping gases into the atmosphere.
Drought Signals
Climate change is making droughts more likely to occur, and more severe when they do.
Wildfires Signals
Climate change is increasing the size, frequency, intensity and seasonality of wildfires.
Hurricanes Signals
Warmer temperatures increase the rate of water evaporation, which feeds moisture and energy into storms.
Floods Signals
Worsening floods due to climate change are putting a growing number of communities at risk.
