Why is sea level rising? Global sea levels are rising as a result of human-caused global warming, with recent rates being unprecedented over the past 2,500-plus years. @NASAJPL’s Ben Hamlington explains how our warming planet is causing sea levels to rise. http://sealevel.nasa.gov/understanding-sea-level

Experiences surrounding Dr. Martin Luther King Jr.’s time spent working on a tobacco farm likely influenced his future as a minister and civil rights activist.

This #Landsat 9 image shows the Meadowood tobacco farm, where King worked, in Simsbury, CT. https://go.nasa.gov/3X8BbmJ
#NASAEarth


The @Space_Station captured this view of Martin Luther King, Jr.’s birthplace, Atlanta, Georgia, in 2013.

@nasa honors Dr. King’s life and legacy by expanding mission equity, engaging in public service, and sharing knowledge for the benefit of humanity. https://go.nasa.gov/3IKKwNg

These swirls of discolored water are signs that Kaitoku, a triple-peaked submarine volcano north of Io Jima, is active. 🌊🌋

@nasa’s #Landsat 8 satellite captured these images on Jan. 3, 2023. Activity started in August 2022 has continued periodically. https://go.nasa.gov/3GFjh4i

NASA’s Aqua satellite took this image of the Antarctic peninsula in Dec. 2022 when sea ice around the continent was breaking up and melting—a seasonal occurrence that usually begins in September and continues into February. 🧊

But the decline so far in the 2022-2023 season has been especially steep.

According to the @NSIDC, the extent of sea ice around Antarctica at the end of December 2022 was the lowest in 45 years of satellite records.

Are humans causing climate change?

@nasa has powerful supercomputers that we use to recreate Earth’s climate and run simulations of different scenarios that could impact Earth’s climate.

And what we’ve seen is… it’s us. Human activities are responsible for climate change.
#NASAEarth


A series of back-to-back atmospheric rivers has drenched much of California since late December 2022, with more on the way. 🌧️

These maps show surface soil moisture (higher in blue) from before the storms (left) and after, on Jan. 9 (right). https://go.nasa.gov/3CDzztd
#NASAEarth


Why is Earth getting warmer?

The release of greenhouse gases, like carbon dioxide, from human activities is responsible for the majority of climate change. In our atmosphere, these greenhouse gases trap heat in the atmosphere, raising Earth’s temperature.
#NASAEarth


How do we know Earth’s climate is warming?

It’s not just us. Our partners at @noaa and other agencies and researchers around the world analyze the temperature records too. Their climate records show the same thing: Earth is warming significantly and rapidly.

Rainfall from Tropical Cyclone Ellie western Australia causing extensive flooding.

Floodwater is apparent in these false-color images from NASA’s Aqua satellite, taken on Dec. 17 (before the flooding) and Jan. 9 (after). https://go.nasa.gov/3ZpgvZm
#NASAEarth


NASA produces a record of Earth’s surface temperature from 1880 until the present day. 🌎 🌡️

On Thursday, we’ll announce where 2022 stands in our temperature record and share more about Earth and the ways it's warming. https://go.nasa.gov/3vWlVxz

Greenland’s largest ice stream is expected to contribute more to sea level rise by the end of the century than models previously indicated.

This animation shows thinning since 2007 and projected through 2100, with the greatest thinning in yellow.

Update: @nasa’s retired Earth Radiation Budget Satellite reentered Earth’s atmosphere over the Bering Sea at 11:04 p.m. EST on Sunday, Jan. 8, the @DeptofDefense confirmed.
#NASAEarth


NASA’s retired Earth Radiation Budget Satellite (ERBS) is expected to reenter Earth’s atmosphere after almost 40 years in space.

The @DeptofDefense currently predicts reentry at approximately 6:40 pm EST on Jan. 8.

An atmospheric river drenched California on Jan. 4 and 5, 2023. 🌧️

A plume of moisture from the tropical Pacific interacted with a low-pressure system that rapidly strengthened over the northeast Pacific, producing an intense storm.

#NASAEarth


The map above shows how much potential liquid water is in the atmosphere on Jan. 4, 2023. The dark green swoop on the map indicates moisture flowing from the tropical Pacific toward California.

Data are from @nasagoddard's GEOS ADAS. https://go.nasa.gov/3GIAQ4u
#NASAEarth


This @NOAA-20 image from Jan. 4, 2023, at 1:20 p.m. PST and shows the storm intensifying.

When air pressure in a mid-latitude cyclone rapidly drops and winds intensify, these storms can undergo a process can become “bomb cyclones.” https://go.nasa.gov/3GK7wdR

This #Landsat image shows an area of central Ireland where multiple peat bogs – water-logged ecosystems that can store thousands of years of carbon in their soil – have been dug up for fuel. https://go.nasa.gov/3CndcIs

2022 ended with a shiver, but the start of 2023 broke a sweat. 🥶🥵

This weather whiplash may have been caused by changes in the polar vortex, the band of strong westerly winds over the Arctic. Details: https://go.nasa.gov/3XaD4iK

Heavy rain on New Year’s Eve 2022 flooded California near San Francisco and Sacramento.

Flooding is visible in the false-color satellite image from Jan. 1, 2023 (right), with water in blue, compared to the image from Dec. 16, 2022 (left).
