A 2 degree celcius rise will doom humans

1. Summary of the results

The claim that a 2-degree Celsius rise will doom humans is a subject of debate among various analyses. Some sources suggest that a 2-degree rise could lead to severe consequences, including heat stress, increased risk of wildfires, and other extreme weather events, which could be catastrophic for human health and the environment ^[1]. Limiting global warming to 1.5 degrees Celsius is also emphasized as a way to avoid risks of extreme changes that could appear if it increased to 2 degrees ^[2]. However, other sources argue that the expected global surface warming for the 21st century will likely be mild, with a temperature increase of no more than 2.5-3.0°C, and on average, likely below the 2.0°C threshold ^[3]. Additionally, some sources highlight the importance of limiting global warming to 1.5-2 degrees Celsius, emphasizing the significant risks to human health, livelihoods, and ecosystems associated with exceeding this threshold ^[4]. The origin of the 2 degree Celsius target is also explained, tracing it back to the work of William Nordhaus in the 1970s and its subsequent adoption as a benchmark for international climate policy ^[5]. Uncertainty and the need for further research are also stressed, rather than a definitive doom prediction ^{[6] [7]}.

2. Missing context/alternative viewpoints

• The evolution of the 2 °C target and its adoption as a benchmark for international climate policy are important contexts that are missing from the original statement ^{[5] [6]}.
• Alternative viewpoints on the severity of the consequences of a 2-degree Celsius rise are also missing, with some sources emphasizing the potential for catastrophic outcomes ^[1] and others highlighting the uncertainty and low-probability high-impact risks ^{[6] [7]}.
• The importance of limiting global warming to 1.5 degrees Celsius is also a key context that is missing from the original statement, with some sources emphasizing the significant risks associated with exceeding this threshold ^{[2] [4]}.
• The role of political negotiation in addressing climate change is also an important context that is missing from the original statement, with some sources highlighting the need for urgent action to reduce greenhouse gas emissions ^[4].

3. Potential misinformation/bias in the original statement

The original statement that a 2-degree Celsius rise will doom humans may be misleading or exaggerated, as some sources suggest that the consequences of a 2-degree rise will be severe, but not necessarily catastrophic ^[1]. Environmental groups and health professionals may benefit from this framing, as it emphasizes the urgent need for action to reduce greenhouse gas emissions and mitigate the effects of climate change ^[4]. However, other stakeholders, such as industries or governments, may be misrepresented or ignored in this framing, as they may have different perspectives on the severity of the consequences of a 2-degree rise and the need for urgent action ^{[3] [6]}. A more nuanced and balanced approach to understanding the consequences of a 2-degree Celsius rise is necessary, taking into account the various perspectives and contexts that are missing from the original statement ^{[2] [5] [6]}.
