地球温暖化がこのまま進めば、人類の繁栄に適した気象条件の範囲から数十億人が外れ、危険な暑さにさらされることになるとの新たな研究結果が報告された
If global warming continues, billions of people will be exposed to dangerous heat outside the range of weather conditions suitable for human flourishing, a new study reports.

チームはこの中で、世界の平均気温が現時点で予想されている通り、今世紀末に産業革命前から2.7度上昇した場合の人間への影響を予測した
In it, the team projected the impact on humans if global average temperatures were to rise by 2.7°C above pre-industrial levels at the end of the century, as currently projected.

気候変動と人口増加の両方を考慮すると、2030年までに世界で20億人、90年までには37億人が、人類の繁栄に適した「気候ニッチ」の外に追いやられ、年平均気温が29度以上という過酷な暑さにさらされるという
Taking into account both climate change and population growth, 2 billion people in the world by 2030 and 3.7 billion people by 1990 will be pushed out of the ”climate niche” suitable for human prosperity, and the average annual temperature is said to be exposed to extreme heat of 29 degrees or more

こうした人々は世界人口の3分の1を占めることになり、地球上で人間の住める場所が変動して、人口分布も一変する可能性があると、レントン教授は指摘する
These people will make up one-third of the world’s population, shifting where humans can live on the planet and potentially altering population distributions, Professor Renton said.

研究チームが世界の人口分布と年平均気温の関係を示したデータによると、これまで最も多くの人口が集中してきたのは年平均気温が13度の地域で、27度前後にもうひとつのピークがある
According to the research team’s data showing the relationship between the world’s population distribution and the annual average temperature, the most populated areas have been concentrated in areas with an average annual temperature of 13 degrees Celsius, with another peak around 27 degrees Celsius. there is
