Climate change is now a full-blown crisis


Today’s Video of the Day from The Sanders Institute introduces The Climate Crisis, a series aimed at bringing urgent attention to the fact that climate change must now be addressed as a full-blown global emergency.

Bill McKibben is an author, environmentalist, and a founding fellow of The Sanders Institute who hosts the series.

“Scientists have warned us for 30 years that we were changing the climate, and now those predictions are coming true with a vengeance,” says McKibben, who has been writing about the climate crisis for three decades.

According to The Sanders Institute, 97 percent of scientists agree that climate change is happening and that humans are causing it.

The new series will highlight ways that the climate crisis could still possibly be averted. McKibben says that we must act “collectively, decisively, and fast.”

NASA database will help predict extreme fire events


Today’s Video of the Day from NASA Goddard features an interview with research scientist Robert Field as he describes the agency’s newest fire monitoring system, the Global Fire Weather Database (GFWED).

GFWED will be the first consistent dataset for use by researchers and land managers around the world. The system will utilize different satellites to provide critical information on rainfall, temperature, and land cover that can help experts identify the conditions that drive extreme fire events.

Farming has a visible impact on Lake Huron


Today’s Video of the Day from the European Space Agency highlights the prevalence of agriculture near Lake Huron, as well as the consequences of heavy farming that are visible along the coastline.

The rich land is farmed to support the growing demand for corn, soybeans, and other crops. The resulting fertilizer runoff from the agricultural industry, however, causes major concerns about harm to the environment such as algae blooms.

Spectacular views of lava river flowing from Kilauea vent


Today’s Video of the Day from the U.S. Geological Survey features unbelievable views of the river of lava that is moving across Hawaii’s Big Island from Kilauea’s fissure 8 to the Pacific Ocean.

The lava can be seen gushing out of a cone that is now 164 feet high and is traveling at speeds of up to 17 miles per hour, according to the Hawaiian Volcanic Observatory.

Fissure 8 is currently Kilauea’s most active vent and shows no signs of slowing down. Since May 3rd, explosive activity from the volcano has covered at least 6,000 acres and destroyed over 500 homes.

Scientists climb Mount Makalu to raise awareness about climate change

Today’s Video of the Day is part of the Earth From Space series by the European Space Agency (ESA) and features images of Mount Makalu in the Himalayas. Swedish explorer and climate campaigner Carina Ahlqvist organized a climb up the mountain to support the ESA’s climate change initiative.

Located between Nepal and China just southeast of Mount Everest, the mountain is the fifth highest in the world. Mount Makalu is also considered to be one of the most difficult mountains to climb due to its extreme ridges and harsh environment.

Data collected on the journey led by Ahlqvist will help scientists understand the dynamics of this remote region and how these dynamics are being affected by changing climate conditions.

Scientists use laser scans to study the Amazon rainforest


Today’s Video of the Day from NASA Goddard describes how laser scans of the Amazon rainforest help researchers track changes that are triggered by climate change and other influences. Airborne laser measurements of the forest’s canopy provide details about structural changes among the massive trees that could not be obtained from the ground or from space.

In particular, the experts use the laser data to investigate how climate change is affecting the ability of the rainforest to store carbon. They also use the observations to examine the impacts that logging and extreme weather events have on the forest.

The Republic of Cabo Verde in the Atlantic Ocean


Today’s Video of the Day comes from the European Space Agency’s (ESA) Earth from Space series and features a look at the Republic of Cabo Verde.

Cabo Verde consists of 10 volcanic islands in the Atlantic Ocean located 350 miles west of the Cape Verde Peninsula in West Africa.

These images were captured by the Copernicus Sentinel-3A satellite and also reveal a considerable amount of dust being kicked up by the wind and carried over the ocean.

Northern Italy and the Alps


Today’s Video of the Day comes from the European Space Agency’s Earth from Space series and features a look at northern Italy and the Alps.

These images were captured by the Copernicus Sentinel-2B satellite and reveal the transition from the stunning mountains down to the lower plains that surround the city of Milan.

Also visible is the southern portion of Lake Maggiore, the longest lake in Italy that also extends into Switzerland.

Changes in global sea surface temperatures since 1991


Today’s Video of the Day comes from the European Space Agency’s (ESA) Climate Change Initiative and features a look at changes in global sea surface temperatures from 1991 to 2010.

This data was collected by ESA’s ERS and Envisat Along Track Scanning Radiometers and the National Oceanic and Atmospheric Administration’s (NOAA) Advanced Very High Resolution Radiometers on board the Polar Orbiting Environmental Satellites.

New expedition to study how clouds impact Arctic melting


Today’s Video of the Day comes from Stockholm University and features a look at a new expedition aimed at investigating how marine microbiology and clouds impact the Arctic climate and rapid rate of Arctic melting.

“The goal is to provide unique measurements that will provide detailed information about basic processes for cloud formation in the Arctic. These results are necessary to understand the Arctic climate and its sensitivity and response to the changes in climate caused by human activity,” said Caroline Leck, professor in chemical meteorology at the Department of Meteorology (MISU) and chief scientist in charge of the expedition.

How the International Space Station affects everyday life on Earth


Today’s Video of the Day features a look at Destination Station, a campaign launched by NASA and the Center for the Advancement of Science and Space (CASIS) to share how work done on the International Space Station impacts our everyday life here on Earth.

Scientists on the International Space Station are able to utilize its unique conditions like microgravity and low-Earth orbit to conduct more than 2,000 experiments by 2,400 researchers from over 95 countries. The research extends from human health, biotechnology, and Earth science.

Mount Mayon in the Philippines


Today’s Video of the Day comes from the European Space Agency’s Earth from Space seres and features a look at Mount Mayon in the Philippines.

Mount Mayon is a stratovolcano located on the island of Luzon and is one of the most active volcanoes in the world. It is known for its symmetrical shape, often referred to as a “perfect” volcano.

These images were captured by the Copernicus Sentinel-1B satellite and shows five of the island’s volcanoes.
