In this episode of NASA Explorers (Season 1 Episode 7), the scientists go back in time – by going underground. In the Arctic, a frozen layer of soil – permafrost, the “permanently” frozen earth – trapped dead plants and animals for thousands of years. As the climate warms, that soil is beginning to thaw, releasing carbon dioxide and methane – two harmful greenhouse gases which contribute to global warming.Continue reading Watch – NASA Explorers: Permafrost
Here is a quick summary of the Earth’s snow cover between March 2000 and December 2018. These snow cover maps are made from observations collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite.Continue reading Snow cover of Earth between Mar. 2000 and Dec. 2018
The polar vortex is a large area of low pressure and cold air surrounding the Earth’s north and south poles. It is the reason why extreme winter conditions are bringing record-breaking cold temperatures to parts of North America.Continue reading Polar Vortex is the reason why the winter is so harsh in North America
Our planet is getting warmer, with an increasing pace. This month, there were three bad, very bad news about global warming. According to a study published in Proceedings of the National Academy of Sciences, Antarctica is losing six times more ice mass annually now than 40 years ago. Another study, published in the scientific journal Advances in Atmospheric Sciences concluded that 2018 was the hottest year ever recorded for the Earth’s oceans. And, according to

Based on the Paris Climate Agreement, more than 6,000 cities, states, and provinces in dozens of countries must drastically reduce greenhouse gas emissions by 2050 to save life as we know it. The latest Intergovernmental Panel on Climate Change report foretells an inhospitable Earth unless we achieve this monumental undertaking.Continue reading Why We Need to Trust Technology to Fight Climate Change
With constant reports of record-breaking heat waves, increased hurricane activity, and deadly winter storms caused by climate change, it can seem hopeless to change course as an individual. Dire warnings about climate change can certainly be discouraging, but making an impact all by yourself isn’t impossible. Even if saving the world isn’t your thing, being environmentally conscious also tends to save you quite a bit of cash. So, how can you help the planet by saving energy at home?Continue reading Environmental Impacts of Saving Energy at Home
In the 1950s, the first reports of increasing global temperatures were found in local newspapers, where journalists referenced scientific studies on climate change. The term was casually used until the 70s when scientists began publishing their papers and other work regarding climate change. In the 80s, NASA climate scientists testified before Congress to the effects of climate change and the studies outlining the causes and potential consequences of rising temperatures.
Now, almost 70 years after the initial introduction to rising global temperatures, among growing natural disasters and extensive scientific evidence, global warming has become a political debate, dismissed by one party and spoken of with urgency by the other.Continue reading Global Warming: Where Are We Now?
A lazy buzz phrase – ‘Is this the new normal?’ – has been doing the rounds as extreme climate events have been piling up over the past year. To which the riposte should be: it’s worse than that – we’re on the road to even more frequent, more extreme events than we saw this year.
We have known since the 1980s what’s in store for us. Action taken then to reduce emissions by 20
An amazing video: a recent NASA long-duration balloon mission observed a thin group of seasonal electric blue clouds which are known as noctilucent clouds or polar mesospheric clouds (PMCs). Forming 50 miles (80 km) above polar regions in summer they are Earth’s uppermost clouds and only visible around twilight. PMCs are composed of ice crystals that glow bright blue or white
