7 NASA Selfies Show Just How Much Our Climate Is Changing

Climate

We’ve all heard the line that “a picture is worth a thousand words.” So to bring home what’s happening to our planet, we rounded up a series of pictures of Earth through the years from the U.S. National Aeronautics and Space Administration (NASA). And while some pictures could use a thousand words to make their point, these images only need four: “Our climate is changing.”

The largest glacier in Yosemite National Park, the Lyell Glacier, has lost almost 80 percent of its surface area and about 120 vertical feet (37 meters) of ice. While this change has occurred over the span of 132 years from 1883–2015, more than 10 percent of the total ice loss has happened in the past four years, thanks to warming temperatures and dry weather.

Scientific research shows glaciers have been losing mass since at least the 1970s and ice mass has been declining more quickly in the last 10 years. This melting ice has contributed to rising sea levels around the world, putting millions of people near coastal areas at risk to severe flooding as storms intensify.

Lake Mead, a reservoir outside of Las Vegas that sustains nearly 20 million people in California, Arizona and Nevada, has suffered from intense droughts in recent years. The reservoir’s water level declined about 120 feet (37 meters) between 2000–2015, hitting record lows as the drought spread across California and southwestern states in the U.S.

But it doesn’t end with dry heat: Droughts mean the water supplies we depend on are affected as bodies of water like Lake Mead decline. A report by the Natural Resources Defense Council found that one-third of all the counties in the U.S.’ lower 48 states are at higher risk of water shortages over the next 35 years because of climate change.

In May 2014, a series of wildfires hit the coastal area north of San Diego, California, thanks to a combination of heat, drought and dry winds that intensified the fires. The wildfires put thousands of nearby residents at risk, resulting in 175,000 evacuation notices.

Over the past decade, wildfires have caused significant damage throughout the western U.S. and other parts of the world and many scientists believe climate change is playing a role. There’s an average of 72,000 wildfires per year and nine of the 10 years with the most burned acres have occurred since 2000. We can’t yet say for sure, but we don’t think it’s a coincidence that the nine worst years for wildfires coincide with many of the hottest years on record.

Typhoon Haiyan, Philippines

On Nov. 7, 2013, Typhoon Haiyan, known locally as Typhoon Yolanda, approached Guiuan on the Philippine island of Samar with winds close to 195 miles per hour (315 kilometers per hour). The storm became the deadliest on record in the Philippines and was responsible for more than 6,300 lost lives, more than 4 million displaced citizens and more than $2 billion in damages. Not all the devastation came when Haiyan first struck, as the storm also swelled the Agno River, shown in the second image above, causing severe flooding later.

Research shows that hurricanes and typhoons are likely to become more intense with stronger winds as the planet, including ocean temperatures, continues to warm. In the northwestern Pacific Ocean specifically, damaging typhoons have become about 10 percent more intense since the 1970s and even stronger storms are expected there as climate change worsens.

Deforestation in the Brazilian Amazon

The images above show what deforestation looks like via satellite in the Amazon, specifically in the Brazilian state of Rondônia. Rondônia has the highest rate of deforestation in the Brazilian Amazon, partly because of the area’s growing population from government-promoted immigration and the expansion of the wood-products industry. Rondônia’s population has more than doubled over the past three decades, from about 500,000 in 1980 to more than 1.7 million today.

Deforestation or the clearing of forests on a massive scale, is a major contributor to climate change and responsible for about 15 percent of all greenhouse gas emissions. In the last 50 years, about 50 percent of the world’s original forest cover has been lost due to deforestation. Deforestation not only releases greenhouse gases into the atmosphere, but it harms many other areas of the environment, including wildlife, water cycles and the livelihoods of people who rely on forests. Plus, as forests decline, so does their ability to act as carbon sinks that help remove greenhouse gases from the atmosphere. Talk about lose-lose-lose.

Population Growth in Beijing, China

The images above show the drastic population growth and infrastructure expansion in Beijing between 2000 and 2009. This has created what’s known as a “heat island effect,” which has contributed to an increase in winter temperatures by 5—7 degrees Fahrenheit (3—4 degrees Celsius).

With a population of more than 1 billion, an expanding middle class and an economy that has been rapidly growing over the past two decades, many eyes are on China to do its part in fighting climate change. Thankfully, that’s what China has pledged to do in a commitment last year to peak carbon emissions by 2030 and source 20 percent of its primary energy consumption from clean energy sources. This was a major win for the climate movement.

Earth’s Temperature Changes

If we had to pick one satellite image comparison to sum up how climate change affects our planet, this would be it. These striking images compare temperatures in each region of the world more than 100 years apart. The left image shows Earth’s temperatures from 1880–1889 and the right image shows temperature from 2000–2009. What the two show is that Earth’s average surface temperature has increased 1.3 degrees Fahrenheit (0.7 degrees Celsius) since 1880, with two-thirds of this increase happening in the last 40 years.

Seen enough before-and-after images? So have we. Which is why it’s worth taking a step back to look at the big picture and see just what’s at stake with a recent shot from NASA’s Deep Space Climate Observatory (DSCOVR).

This beautiful planet is our home and it’s our responsibility to protect it from the devastation of a changing climate. Ready to learn how you can help?

VIETNAM, July 2019 – I'm chasing a ghost, I think not for the first time, as night falls and I gather up my gear in a hotel in a village in southern Vietnam. I pack my camera, a bottle of water, and a poncho; outside the window I can see a light rain.

The most destructive hurricanes are three times more frequent than they were a century ago, new research has found, and this can be "unequivocally" linked to the climate crisis.

The Office of Disease Prevention and Health Promotion and the World Health Organization currently recommend either 150 minutes of moderate intensity exercise (walking, gardening, doing household chores) or 75 minutes of vigorous aerobic exercise (running, cycling, swimming) every week.

But there's little research looking at the benefits, if any, of exercising less than the 75 minute minimum.

For 21 years, Doug Distaso served his country in the United States Air Force.

He commanded joint aviation, maintenance, and support personnel globally and served as a primary legislative affairs lead for two U.S. Special Operations Command leaders.

But after an Air Force plane accident left him with a traumatic brain injury, post-traumatic stress disorder (PTSD), and chronic pain, Distaso was placed on more than a dozen prescription medications by doctors at the U.S. Department of Veterans Affairs (VA).

If you had to choose a diamond for your engagement ring from below or above the ground, which would you pick … and why would you pick it? This is the main question consumers are facing when picking out their diamond engagement ring today. With a dramatic increase in demand for conflict-free lab-grown diamonds, the diamond industry is shifting right before our eyes.

The scourge of plastic waste that washes up on once-pristine beaches and finds its way into the middle of the ocean often starts on land, is dumped in rivers and canals, and gets carried out to sea. At the current rate, marine plastic is predicted to outweigh all the fish in the seas by 2050, according to Silicon Canals.
