Andrei's background is in geophysics, and he's been fascinated by it ever since he was a child. Feeling that there is a gap between scientists and the general audience, he started ZME Science -- and the results are what you see today.

CLIMATE STRIKE
ZME Science is supporting and participating in the September 2019 Climate Strike.

Our planet is burning up. Throughout Earth’s history, the planetary climate has varied substantially over geologic time -- but this time, it’s different.

There is unequivocal scientific evidence that our emissions of greenhouse gases (most notably CO2 but also methane and others) are fueling this heating and without strong and timely measures, the damage will be catastrophic.

We are already approximately 1 °C (1.62 F) above pre-industrial levels. Limiting the heating to 2 °C (or even better, 1.5 °C) is mandatory if we want to prevent irreversible, catastrophic damage to the environment, to our society, and potentially to ourselves as a species. This would require sustained global action from all the world’s countries -- and this is just not happening.

The science is in. We know the cause of the problem, and we know how to fix it. All that’s required now is the political and social impetus to bring forth these healthy changes. If we continue with “business as usual”, we will be the ones responsible for unprecedented disasters. We have to do more to ensure a sustainable, low carbon transition. We owe it to this planet, we owe it to ourselves, and we owe it to our children.

Today, ZME Science will not be publishing any new stories. We will be highlighting scientific evidence on climate change and what can be done to limit it.We hope you will join us in the quest for building a better world for ourselves and future generations.

Thank you!
