Climate change is real. The #water crisis is the No1 global risk based on impact to society and it is caused, in part, by climate change. Here are a few things you can do daily to make a difference: change your #diet , go #vegan; don't let the water run while shaving or brushing your teeth; take shorter showers; don't wash your car that often-let the rain do it for you ;) Conserve water. Use it mindfully. l #Repost @nasagoddard
Happy World Water Day 💧🌍💧 We're raising #awareness and celebrating by sharing our favorite water #planet , Earth!
Viewed from space, the most striking feature of our planet is the water. In both liquid and frozen form, it covers 75% of the Earth’s surface. It fills the sky with clouds. Water is practically everywhere on Earth, from inside the rocky crust to inside our cells.
This photo-like view of Earth is one of many images of our watery world featured in a new story examining water in all of its forms and functions. Here is an excerpt: “In all, the Earth’s water content is about 1.39 billion cubic kilometers (331 million cubic miles), with the bulk of it, about 96.5%, being in the global oceans. As for the rest, approx 1.7% is stored in the polar icecaps, glaciers, and permanent snow, and another 1.7% is stored in groundwater, lakes, rivers, streams, and soil.
Only a thousandth of 1% of the water on Earth exists as water vapor in the atmosphere. Despite its small amount, this water vapor has a huge influence on the planet. Water vapor is a powerful greenhouse gas, and it is a major driver of the Earth’s weather and climate as it travels around the globe, transporting heat with it.
For human needs, the amount of #freshwater for drinking and agriculture is important. Freshwater exists in lakes, rivers, groundwater, and frozen as snow and ice. Estimates of groundwater are particularly difficult to make, and they vary widely. Groundwater may constitute anywhere from approximately 22 to 30% of fresh #water , with ice accounting for most of the remaining 78 to 70%.” NASA image by Robert Simmon and Marit Jentoft-Nilsen, based on MODIS data.
