How can we “see” water from space? 🛰️ This visualization uses data from the GRACE-FO mission to show how wet or dry conditions have been over the past year — from moisture near the surface to water stored underground.

NASA’s Carruthers Geocorona Observatory has begun its 2-year science mission. 🛰️ From ~1 million miles away, the spacecraft is capturing the UV glow from Earth’s outer atmosphere. The data will help us understand how hydrogen (and water) from Earth escape to space. 🌎💦🌌 More:

Earth's ocean currents 🌊 This data visualization is showing how the ocean moves water across the planet using data from NASA’s ECCO model, or Estimating the Circulation and Climate of the Ocean. The model pulls data from spacecraft, buoys, and more. Researchers rely on the model output to study ocean dynamics and to track conditions that are crucial for ecosystems and weather patterns.

Farming information from space 🧑‍🌾🛰️ The @nasa @usgs Landsat and European Space Agency Sentinel-2 satellites can ‘see’ more than human eyes can. Combining near-infrared and visible light data allows us to monitor where crops are growing and how healthy the plants are.

POSOBIEC: "The climate agenda's fall from grace over the past year has been stunning — in speed, scale and scope." - this is from Axios!

🚨 JUST IN: Florida Gov. Ron DeSantis has just BANNED AI data centers from using up all the water needed by citizens during a drought And the law BANS utility companies from charging higher prices because of data centers "How are you going to say that somehow the water can go to a data center when we need to water for our own people and for the core functions of our society?"

The Rio Grand River is extremely dry A combination of drought and heavy water use is now resulting in entire stretches of the river being bone dry 87% of the water goes to agriculture. META’s data center is using 75 million gallons per year. There are also 21 operating or planned data centers Mexico uses the water for their agriculture as well No foreign country should get water when its this dry

No heating, no water, no electricity This is how Odesa looks after the Russian attack. The innocent Ukrainians suffer from the russian terrorism. We have to stop it.

This is before/after footage from Hurricane Helene. It cannot be overstated how resilient, kind, hard-working, and selfless the people of Appalachia have been to each other over the past year. We are Appalachian Strong ❤️

♨️Hot water from Poolbeg Incinerator will heat over 50,000 buildings from 2025 Currently the #Waste to #Energy facility uses energy from burning rubbish to feed power into the electricity grid... but the excess hot water is pumped into the Liffey (1/2)

Thirsty grapes? 🍇 The NASA/USGS Landsat can spot them from space! Through the research project, GRAPEX, scientists used Landsat data to estimate crop water use. This led to a free tool called OpenET, which helps farmers across the U.S. use water more efficiently.

James Talarico: “We have to stop data centers from jacking up our utility bills. We have to stop data centers from using up all our water. We gotta stop data centers from getting sweetheart tax deals. And we gotta stop data centers from being built if they can’t meet the demands of our communities”

The Rio Grande River in Arizona is completely dry in many locations They don’t want you to know, the majority of this water has been sold off over the past 5 years - A huge amount goes to agriculture, about 87% - Mexico gets an enormous amount of the water because of the US-Mexico Water Treaty Mexico is supposed to send about 1/3 of the water from certain rivers that flow into the Rio Grande to the US, mainly for Texas farmers - Minimum: Average of 350,000 acre-feet per year or 1.75 million over 5 years. - Mexico keeps the other 2/3 of that water for its own farms and cities - The US sends Mexico a lot of water from the Colorado River about 1.5 million acre feet per year During 2020-2025 Mexico only delivered about 50% of the water it owed to the United States at the end of the 5 year period Mexico continues to keep way more than their agreed share
