 Global temperatures are rising rapidly and are already beyond the natural range of the current interglacial period, the Holocene. This means that Earth is experiencing a climate emergency, and unless drastic measures are taken, the planet will continue to experience increasing temperatures and sea levels will rise significantly. To avoid this, we must reduce our reliance on fossil fuels and transition to renewable sources of energy. Additionally, we need to take action to protect and restore ecosystems, as these can help absorb some of the excess carbon dioxide in the atmosphere. This article was authored by J. Hansen, M.
