349ppm

2024 January 15th


Last year, I got this tattoo to commemorate my three rounds of the zodiac. 349ppm is the CO2 level in the atmosphere in the year I was born. Many climate scientists say we should stay below 350ppm to make the planet safe and inhabitable. (the pre-industrial time, it was around 280ppm) It is somehow significant for me that I was born in the year that it was barely okay, and it has kept worsening since. Alarmingly, it reached 421ppm last year. You might be thinking "Is it that bad?" And I would say “Yes, REALLY bad” - because the last time CO2 levels exceeded 400ppm (not even 420ppm) was around four million years ago, during the Pliocene era when global temperatures were 2-4C warmer and sea levels were 10-25m higher than today.

I placed the tattoo here so that I can see it many times a day. It works as a reminder that ecological breakdown keeps happening even if I do not see it with my own eyes. And I should do some actions every day, even if it seems minor. Some friends asked me the meaning of the tattoo – that was a good way to start a chat about climate and environment.

What is happening in Gaza makes me feel so powerless. I lost the motivation to act on environmental issues for a while. But all the injustices are connected. I think that having sincere compassion for others (including other species) and demanding ethical standards have become more crucial than ever. Climate justice can only exist if everyone is free.
去年、干支を3周した記念にタトゥーを入れた。349ppmは空気中のCO2の濃度を意味している。気候変動を研究する人たちの間では、安全で人間や生き物が生き続けられる地球を保つためにはCO2濃度を350ppm以下にするべきだと言われているのだけど、2023年CO2の濃度は421ppmを超えた。それがどれくらいやばいかというと、以前に400ppmを超えたのは人間が今のような暮らしをし始めてからは記録がなく、遡ること約400万年前で、その時は2-4度地球の平均気温が高く、海面が10-25m高かったとされている。

目につく場所にタトゥーを入れることで、普段の忙しい生活の中でも気候変動が起きていることを忘れないようにという思いを込めた。いくら自分の行動に意味がないように感じても、冬で気候変動を肌で実感しなくても、何かしらのアクションをしようというリマインダー。

ガザで起きていることを目の当たりにして、さらなる無力感に苛まれ、気候変動や生物多様性のための行動への気力が落ちていた。画面越しの同時代に起きている虐殺を見ながら、他者(広くは他の生き物も含め)の痛みへの想像力を失うことで、あるべき社会が崩れていくということに尽きるとも思った。何か危機が起きた時に切り捨てられる人々がいることを容認してはいけない。その不正義をなくすためにも自分のできることをしていきたい。
