NASA satellite images capture extreme weather events in 2020

NASA satellite images capture extreme weather events in 2020

Besides a deadly pandemic, 2020 also provided a reminder of its severity Climate crisis Facing the world – droughts and floods, Heat wavesAnd the Forest fires Hurricanes continue to disrupt the lives of communities around the world, in addition to the challenges that the Covid-19 virus has brought and despite it.

Images of some of these climate events – both visually stunning and equally real – were captured by NASA’s fleet of Earth observation satellites and instruments on International Space Station.

On this day last year, NASA’s Moderate Resolution Imaging Spectrophotometer captured images of dense tan smoke drifting across southeastern Australia, captured as the country ravaged one of the worst wildfire seasons on record.

Australia’s fire season is always dangerous – but conditions were extraordinarily severe in 2020, fanning the fires and making the firefighting conditions extremely challenging.

Experts say climate change has exacerbated the scale and impact of natural disasters like fires and floods – weather conditions are getting harsher, and for years, fires started early in the season and spread more strongly.

2020 was also a year that many residents should remember West Coast states of the United StatesDeadly wildfires in California, Oregon and Washington have pushed tens of thousands of people into shelters amid the coronavirus pandemic.

In the image below, taken on September 9, a thick blanket of smoke can be seen along the West Coast.

“Climate and fire scientists have long predicted that fires in the western United States will increase in intensity, intensity and severity. But even the most experienced of them were at a loss in describing the scale and intensity of the fires raging in the West Coast states during September 2020.”

This image shows North America on September 9, 2020, as a thick blanket of smoke blanketed the West Coast.

Many this year The fires were caused by lightning strikes, but extreme conditions including record temperatures, dry air, strong winds and droughts caused the fires to destroy neighboring forests and, ultimately, homes.

The VIIRS, Ozone Mapping Sensors and OMPS array, on the NOAA-NASA Suomi NPP satellite, have collected daily images of dense plumes of aerosol particles blowing across the western United States, according to For NASA it was on a scale rarely seen by satellites and scientists.

On July 3, 2020, Landsat 8 operational ground imager captured this false-color image of the river near Rosario, a major port city in Argentina.

Although this photo appears to show a lush and green oasis, the NASA Landsat photo actually reveals the dry river basin of the Argentine Parana River.

2020 was supposed to be the year of climate action.  Instead, a lost contract was crowned

A prolonged period of unusually hot weather and drought in southern Brazil, Paraguay and northern Argentina caused the river to plummet to its lowest level in decades. The drought has not only contributed to an increase in fire activity in the delta and surrounding floodplains, but it has also affected local businesses and residents, with ships grounding and falling water levels costing millions of dollars to make the grain.

It was human activity Linked to the risk of drought in the world Since the beginning of the twentieth century: greenhouse gases from power plants, agriculture, cars, trains, and human activities in general have affected drought risks, and experts predict that droughts linked to climate change will worsen.

Hurricane Laura, one of the 10 most powerful hurricanes to make landfall in the United States, swept southwest of Louisiana in August, killing at least six people and leaving a wide path of devastation.

The 2020 Atlantic hurricane season was Most Active in Registration, The many storms that struck the Gulf Coast, Central America and the Caribbean last year showed signs of a worsening cargo load due to global warming.
The Visual Infrared Imaging Radiometer (VIIRS) group at NOAA-20 obtained this image of Hurricane Laura at 2:20 AM CST on August 26, 2020.

In the image above, captured by VIIRS on the NOAA-20 satellite, a storm looms off the US coast, highlighted by the darkness of the night, while infrared clouds are visible using brightness temperature data and superimposed on images showing city lights.
