Toxic algae blooms are becoming more frequent in some lakes, including Chile’s Lake Villarrica seen in this #Landsat image.

The blooms are likely caused by warmer surface waters and nutrient-laden runoff from urban or agricultural areas. https://go.nasa.gov/423UHCA

In Spain, a drought turns the world’s largest olive oil producing region brown.

NASA’s Terra satellite shows where green vegetation in May 2022 (left) turned brown by May 2023 (right). The drought dried up reservoirs, parched olive groves, and led to water restrictions.

Petermann Glacier, one of Greenland’s largest glaciers that ends at the ocean, is thinning, retreating, and its flow is accelerating.

These satellite images show the glacier in August 2002 (left) and 2022 (right). https://go.nasa.gov/43bj6ra
#NASAEarth

As the glacier stretches and thins, it becomes more prone to rifts that can break and form icebergs.

Climate change is causing rising sea levels, longer and more intense heat waves, melting ice, extreme weather events and more.

But there are other, often surprising, ways Earth’s changing climate is affecting our world. 🧵 https://go.nasa.gov/3pNh4Pg
#NASAEarth

Climate change may make airline flights bumpier. 🛩️

Climate change may strengthen vertical wind shear in jet streams – creating irregular air motions, or turbulence. Pilots use or avoid jet streams to make flights more efficient.
#NASAEarth

As Arctic sea ice melts due to climate change, sailing through the Arctic Ocean could become easier and shorten travel times.

However, traveling over sea ice using snowmobiles, trucks or other vehicles could become unsafe as the ice thins. 🧊
#NASAEarth

Climate change is expected to increase the frequency and intensity of droughts and floods.

Water levels in rivers and reservoirs could shift drastically, impacting cargo ships. 🚢 https://go.nasa.gov/3pNh4Pg
