As global warming ramps up, expect to see Greenland in the news a lot. That’s because its ice sheet is under threat of melting. But that’s not the only reason. The other reason is fire.Continue reading “There’s A Fire in Greenland… Again. It’s 10 Degrees Hotter Than Normal”
Between the scientific community, governments, humanitarian organizations, and even military planners, climate change is considered to be the single greatest threat facing humanity today. Between the increases in famine, disease, flooding, displacement, extreme weather, and chaos that result, it is clear that the way we are causing our planet to get warmer is having dire consequences.
But there a number of scenarios where the harm being done now could result in a runaway effect leading to mass extinctions. This possibility was illustrated in a recent study conducted by MIT professor Daniel Rothman with the support of NASA and the National Science Foundation (NSF). According to Rothman, we are in danger of breaching a “carbon threshold” that could lead to a runaway effect with Earth’s oceans.Continue reading “New Study Shows How Breaching “Carbon Threshold” Could Trigger Mass Extinction in Earth’s Oceans”
To the scientifically uninitiated, it might seem like a frivolous idea: That those slight, wispy clouds that trail behind jet aircraft at such high altitudes could contribute to climate change. But they do.
Scientists love to measure things, and when they measured these contrails, which is short for condensation trails, they found bad news. Though they look kind of beautiful and ephemeral on a summer day, they pack an oversize punch when it comes to their warming effect.Continue reading “Airplane Contrails are Contributing to Global Warming Too”
The Raikoke Volcano, dormant for a very long time, has awoken from its slumber. The volcanic island is in the Kuril Island chain, near the Kamchatka Peninsula in Russia. Unlike its more volcanically active neighbours, Raikoke has been dormant since 1924.
Thanks to astronauts on the International Space Station, we have gorgeous photos of the eruption.Continue reading “Eruption of the Raikoke Volcano, Seen From Space”
Great news! Humankind’s greatest-ever engineering project is nearing completion. Soon we will have warmed the Earth enough to get rid of all those pesky ice sheets and other frozen areas. The finish line is in sight.
If we all work together for the next thousand years, we’ll finally reach our goal!Continue reading “NASA Model Shows Greenland’s Ice Sheet Will Disappear Over the Next 1000 Years, Raising Sea Levels by 7 Meters”
There are a handful of major science institutions around the world that keep track of the Earth’s temperature. They all clearly show that the world’s temperature has risen in the past few decades. One of those institutions is NASA.Continue reading “NASA’s Long-Term Climate Predictions have Proven to be Very Accurate, Within 1/20th of a Degree Celsius”
Scientists at the University of Munster have discovered that Earth got its water from a collision with Theia. Theia was the ancient body that collided with Earth and formed the Moon. Their discovery shows that Earth’s water is much more ancient than previously thought.

Think about this for a minute: We humans and our emissions are helping turn back the climatological clock by 2 or 3 million years, possibly more. Not since that time, called the Pliocene Epoch, has the CO2 ppm risen above 400.
Way back then, the CO2 helped keep the Earth’s temperature 2 to 3 degrees C warmer than it is now. And the Earth was a much different place back then.Continue reading “Today is the Highest Concentration of Atmospheric CO2 in Human History. 415 Parts Per Million. Last Time it Was This High, There Were Trees at the South Pole”
Remember when Orson Welles’ 1938 radio show called “The War of the Worlds” fooled people into thinking that Earth was actually being invaded? That was fun.
Now, the ESA (European Space Agency) is tempting fate by live-tweeting the hypothetical approach of the hypothetical asteroid 2019PDC and hypothetically planning a hypothetical response to this hypothetically destructive asteroid. In their hypothetical scenario, 2019 PDC has a 1 in 10 chance of striking Earth in 2029. And you can follow the action on Twitter.Continue reading “The World’s Space Agencies are Responding to a Hypothetical Asteroid Impact. You Can Watch it all Unfold Online.”
Earth’s fleet of satellites is in a vulnerable position. When solar activity increases, high-energy particles are directed toward Earth. Our large fleet is in the direct path of all that energy, which can damage them or render them inoperable. But now we have another tool to help us protect our satellites.Continue reading “Space Weather Forecasts can now give Satellites One Whole Day of Warning when a Killer Solar Storm is Inbound”
