Our Atmosphere is Escaping!

Earth's atmosphere, crucial for life, is slowly leaking into space. To escape Earth's gravity, objects must reach 34 times the speed of sound, requiring significant energy. Hydrogen and helium are the primary gases escaping, influenced by solar heat and magnetic field interactions. The solar wind affects Earth's magnetic field, allowing particles to escape. Mars, lacking a magnetic field, loses its atmosphere more rapidly. Despite Earth's protective measures, hydrogen loss continues, but it will take billions of years to deplete.

What would happen to Earth's atmosphere if it did not have a magnetic field?

What is the estimated time frame for Earth to lose all its hydrogen due to atmospheric escape?
