New research led by geophysicist Martin Siegert suggests that extreme climate events in Antarctica, such as the recent heatwave and the significant loss of sea ice, are now virtually certain to continue. These changes have global implications, as Antarctica's ice plays a crucial role in regulating Earth's temperature and sea levels. The loss of ice leads to increased heating, triggering more extreme weather events and rising seas. The researchers warn that with continued high levels of greenhouse gas emissions, global sea levels may rise by more than 1 meter this century and even more thereafter. Reducing greenhouse gas emissions to net zero is crucial for preserving Antarctica and addressing the global consequences of climate change.
Despite widespread dislike for Vladimir Putin, many world leaders are hesitant to openly support his ouster due to concerns about the potential chaos and instability that could follow. The lack of a clear successor and the possibility of a violent warlord taking charge leave too many uncomfortable variables. The United States, while taking steps to weaken Putin through economic sanctions, has repeatedly stated that it does not back regime change in Russia. The international community is also concerned about the safety of Russia's nuclear arsenal and the rekindling of frozen conflicts in neighboring countries. The preference is to avoid outright demands for regime change, as past efforts have resulted in violence and long-term failure. However, some officials acknowledge the gravity of the challenge facing Putin and believe that cracks are emerging in his power.
