Group 1 - The mainstream academic consensus is that climate change is significantly accelerating, leading to an increase in extreme weather events [2][5] - Human activities are identified as the primary cause of the surge in greenhouse gases, with current warming rates being 50 times faster than natural climate variations [5][6] - The greenhouse effect, while beneficial to a certain extent, can become dangerous if it exceeds a certain threshold, potentially leading to catastrophic climate scenarios [7][8][11] Group 2 - Global warming is expected to cause both droughts and floods, as increased temperatures enhance evaporation and alter precipitation patterns [12][14][15] - The frequency of extreme weather events, such as unprecedented heavy rainfall, is rising, posing challenges to existing infrastructure built on historical climate data [17][19] - A critical concern is the potential for irreversible changes, such as the melting of ice caps and the release of methane from permafrost, which could accelerate global warming [23][24] Group 3 - There are some potential benefits from global warming, such as the northward shift of precipitation lines, which has led to increased rainfall in certain regions [25][26] - Efforts to combat desertification and improve vegetation cover in arid areas have shown positive results, indicating that proactive measures can mitigate some effects of climate change [28] - However, the overall economic impact may not shift significantly, as major economic activities remain concentrated around oceans and rivers [29][30] Group 4 - The increasing severity of extreme temperatures poses risks to human habitation, particularly in regions experiencing unprecedented heat [32][33] - The social implications of climate change, including exacerbated inequalities and threats to vulnerable populations, are becoming more pronounced [36]
