Prolonged Drought Contributed to Maya Civilization’s Collapse

drought-maya-civilization

The Maya civilization, which occupied much of modern-day Mexico and Central America, collapsed rapidly between 800 and 1000 AD. This collapse has often puzzled archaeologists. There hasn’t been a clear explanation for why the society collapsed, which was known for its sophisticated calendar system and pyramid construction.

Changing Gulf Stream is Destabilizing Gases Trapped in Sediments

Methane gas is escaping from the seabed sediments somewhere off the coast of North Carolina. Researchers think that a shifting Gulf Stream, the Atlantic Ocean current that flows north from the Gulf of Mexico, is to blame since it is delivering warmer waters to areas that had previously only received colder waters.

While it may seem that melting arctic snow isn’t as dramatic as the record ice melt that’s occurred this year, the loss of arctic snow potentially has profound consequences for weather patterns, especially in the USA.

Amazon Fire Analysis Might Close Gaps in Climate Models

amazon-burning

Brazilian and British scientists have been examining the heavy smoke plumes from wildfires in the Amazon, gathering data, to understand how the burning of biomass in South America is affecting the local weather and air quality. This might help close crucial gaps in climate models about how the process changes the Earth’s radiation balance.

Unusually High Frequency of Heatwaves Indicates Human Influence on Global Warming

heatwave-2006-usa

There has been a definite, palpable impact on the Earth’s climate by global warming. The unusual high frequency of heatwaves indicate that there has to be a human influence. As much of the USA sizzles through another scorching summer and the Midwest endures a historic drought, NASA’s climatologist James Hansen states that the future he predicted in 1988 has finally arrived.
