Dear MEL Topic Readers,
World's oceans hit record-high July temperatures
Oceans regulate the climate, absorb excess heat, and produce half of
the planet’s oxygen. Ocean warming expands seawater and causes sea level rise,
marine heatwaves that affect ocean biodiversity, and evaporates more heat and
moisture into the air, which intensifies tropical storms. El Niño is an unusual
warming of ocean surface waters in the tropical Pacific. Combined with global
warming, it can cause temperature spikes and more extreme weather conditions,
including heatwaves and drought. This year, the effects of El Niño are seen in
many places. Western Europe experienced the hottest June-July period, about
2.8 degrees Celsius above average, and the US recorded the hottest-ever July. Record-high
temperatures and heatwaves cause rapid evaporation, sucking moisture from
soils, plants, and reservoirs, and severe droughts across Europe and the western
US, triggering intense and widespread wildfires in Spain, France, and Canada. Global
warming fuels El Niño, and El Niño intensifies extreme weather conditions. How
hot and dry is this August going to be?

Northern Hemisphere.
