Hi, my name is Jemmy! I’m a CO2 molecule. There are lots of things a CO2 molecule can do. My brothers are melting Greenland's ice. My sisters are helping the fires in Australia.

I haven’t figured out my purpose yet so I'm going to travel the world. I’m so ready to spend a long, long time on this amazing planet and share my journey with you!


TUVALU I'm a teeny, tiny island archipelago in Oceania and I'm warming up, fast. I'm sad because I love the people who live here and I want them to be safe, but the global CO2 emissions leave them vulnerable to coastal erosion and sea level rise. There is very little time before they might have to leave to live somewhere else. The people shouldn't have to leave their home because of rich countries that emit almost all the greenhouse gases. There must be justice! For now, Tuvalu's leaders have built sea walls and worked to raise the land to try to keep people safe.


Adaptation will only take us so far, because greenhouse gas emissions exceed our ability to adapt, especially as our climate becomes increasingly unpredictable.

Like Tuvalu, many small island nations are vulnerable and their residents might be displaced. The impact of greenhouse gas emissions in NYC directly and indirectly impact me. This is because of the global atmospheric and oceanic circulation systems.

Maybe I should just hang out in the atmosphere for a bit until more of my friends join me? Then we can jump into the ocean together and make a difference to its pH.

If there aren’t enough of us going into the ocean, the phytoplankton will eat me through photosynthesis. The biological pump will take me all the way down to the dark, cold deep ocean and bury me in sediment. I don’t want to live there for the next million years! I will be so cold and lonely!


Planting mangroves as part of CDR

Look! People living in Tuvalu started to plant mangroves. It's only a small group still, but let's see what they can achieve!

Mangroves help pull CO2 out of the atmosphere. They use their chloropasts which turn CO2 into glucose through photosynthesis. It's like the mangrove leaves are eating the CO2 with their mouths - their stoma!

The mangrove trees keep growing using all the glucose! Their trunks get thicker and their roots thrive in the soil. Then they eat more CO2!

Look! More people are joining together to plant mangroves. The community knows the mangrove forests are important for the environment, economy and the climate! People are working to manage the mangroves sustainably so the trees keep helping the community. , e t i n u s e i t i n u m When com y B ! g n o r t s e r a y e th y e h t , r e h t e g o working t e t a m i l c e t a g i t i m can help d i r t e g n a c y e h T change. ! s d n e i r f s t i d of Jemmy an

Thank you for joining us on Jemmy's journey! Let's keep working together to make sure our world doesn't warm more than 1.5C! And let's support small, island nations like Tuvalu which are experiencing the worst effects of climate change but which have contributed the least towards causing it!
