Each week the NASA State of Flux gallery features images of different locations on planet Earth, showing change over time periods ranging from centuries to days. Some of these effects are related to climate change, some are not. Some document the effects of urbanization, or the ravage of natural hazards such as fires and floods. All show our planet in a state of flux.
MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.
BRIEFING ROOM
Paris Climate Agreement
• STATEMENTS AND RELEASES
ACCEPTANCE ON BEHALF OF THE UNITED STATES OF AMERICA
I, Joseph R. Biden Jr., President of the United States of America, having seen and considered the Paris Agreement, done at Paris on December 12, 2015, do hereby accept the said Agreement and every article and clause thereof on behalf of the United States of America.
Done at Washington this 20th day of January, 2021.
JOSEPH R. BIDEN JR.
NRDC (The Natural Resources Defense Council) works to safeguard the earth and the natural systems on which all life depends. It’s a tall order. Here’s how you can help!
Sign NRDC's petition calling on the Biden-Harris administration to use its crucial first 100 days in office to take key actions to protect the climate, our public health, and our environment. They are off to a promising start, acting in their first week in office to rejoin the Paris climate accord, cancel permits for the Keystone XL pipeline, halt rollbacks to clean car rules, impose a temporary moratorium on drilling on federal lands, and more. But after four years of destruction and neglect under the Trump administration and decades of inaction before that, there is much more to do and no time to waste. CLICK HERE TO SIGN.
