WhatsAppThe energy you use isn''t lost, but stored by your body as gravitational potential energy, which you could use to do other things (whizzing down a slide back to ground level, for example). What you do when you climb steps, ladders, mountains, or anything else is work against Earth''s gravitational field.
WhatsAppThis decreases the amount of solar radiation reflected out to space and increases the amount that is absorbed by the Earth''s surface and oceans. The added energy warms the polar regions, accelerating the rate of ice to melt and thus causing more warming. As the polar regions warm, the land, ice, ocean, and living things are affected.
