Why Antarctic Sea Ice Stopped Growing In 2015
Though numerical models and popular films like An Inconvenient Truth projected Arctic ice collapse due to global warming and then climate change, the reverse was true in the real world. Ice expanded. That changed in 2015 and a new model estimates why. The authors say the Southern Ocean which surrounds Antarctica has gotten warmer, bringing salty water from the deep up to the surface.Those water changes led to record-breaking lows in 2023, which could destabilize the world’s ocean current systems, and it will be due to three changes.In 2013, they write stronger winds led to salty Circumpolar Deep Water getting closer to the surface.
Wealth Correlated To Loneliness
You may have read that Asian cultures respect the elderly more than Europe but Asian senior citizens may not agree. However, it may not be that young people have gotten less respectful, it could be that young people are wealthier than in the past.

Yet a new cross-temporal meta-analysis says that despite the changes in wealth which make socializing more possible, young people report more loneliness.
