This before/after comparison shows the dramatic reduction in pollution since the COVID-19 pandemic forced people to work from home.

NASA released the images below which show NO2 levels in 2019 (on the left), before the COVID-19 pandemic, and in 2020 (on the right). The reduction in NO2 pollution levels is dramatic. The pandemic gave NASA a once-in-a-lifetime opportunity to study human impact on the climate. Even before the pandemic has ended, it is already clear that mankind produces a dire impact on the planet's climate - and shows us how easily and quickly we can turn it around if we try.

The mural on the side of this building absorbs as much pollution as 780 trees!

Big cities don't just contribute to the pollution problem, the lack of trees and other greenery robs the landscape of its ability to heal itself. But scientists have found a way around this problem - photocatalytic paints. Located on a busy metro street in Warsaw, the mural on the side of this building was painted with photocatalytic paint dosed with titanium dioxide. Photocatalytic paints use light energy to neutralize pollution. Add a bit of titanium dioxide and the chemical reaction is even stronger. The reaction between the paint and pollutants converts Nitrogen Oxides and other harmful airborne pollutants into harmless nitrates. The paint is called KNOxOUT (nitrogen oxide, NOx - get it?) and it absorbs the nitrogen oxides created by cars, factories, and power stations. Sunlight acts

Largest solar flare since 2017 has scientists excited that maybe the Sun is entering a new, active cycle.

The Sun has been really quiet lately. In fact, since late in 2017, the Sun's activity seems to have slowed down. That changed this week when scientists spotted the largest solar flare since October 2017. A solar flare is a burst of radiation coming from sunspots (relatively cool patches on the surface of the Sun). The solar flare occurred on May 29 and was rated a M-class. Flares are rated as A, B, C, M, or X. An M-class flare is a medium sized flare and is not big enough to cause problems such as radio interference. The flare has scientists excited that maybe the Sun is moving back to a more active phase of its normal 11-year cycle. The Sun's cycles can range from 9 to

How does global warming cause changes to our normal weather patterns?

The jet stream drives weather patterns The jet stream is a strong wind current flowing about 10 miles above the ground. In the Northern Hemisphere, it almost always blows from west to east and always in a fairly straight line. The jet stream is extremely important to weather systems – it drives the weather patterns throughout the year. The strength of the jet stream, and to what degree it impacts our weather, is determined by the temperature difference between the Arctic and the southern half of the world. CO2 causes temperatures to rise The level of CO2 in our atmosphere has been measured atop the Mauna Loa volcano in Hawaii since around 1958. At the time measurements began, the CO2 measured 315 parts per million (ppm). Today it

Black snow falls in Siberia – and it’s toxic and dangerous to the people who live there.

In early 2019, black snow fell from the sky in several towns in the Siberian region of Kuzbass. About 2.6 million people live in the area. Most work in the area’s coal fields which are the world’s largest. Scientists say the snow is tainted with black coal dust that has been released from the area’s coal pits – and this isn’t the first time black snow fell from the sky. In fact, it’s a common occurrence in the area. One resident told reporters: “It’s harder to find white snow than black snow during the winter. There is a lot of coal dust in the air all the time. When snow falls, it just becomes visible. You can’t see it the rest of the year, but it is

This company is trying to solve climate change by using giant machines to suck CO2 out of the air.

As we consume oil (by driving cars) and coal (by generating electricity) that we extracted from the ground, it releases large amounts of carbon dioxide into the atmosphere which causes our planet to heat up. Kids around the world say the same thing – “Let’s just remove all the carbon dioxide from the air and put it back into the ground where it came from.” Meanwhile, scientists pooh-poohed the “silly idea” saying, “They’re just kids! What do they know!” Well today kids can triumphantly raise their fists in the air and shout “We told you so!” A company out of British Columbia has created a machine that can suck carbon dioxide out of the atmosphere and put it back into the ground! The company is Carbon

Let’s be #ClimateHeroes! Here’s what you can do to battle climate change and be the generation that literally saves the world!

Science will help reverse climate damage but there are still lots of things you can do to battle climate change while we wait. Together we can beat climate change and become the generation that literally saves the world! Let's become #ClimateHeroes! Here's how: Can we beat climate change? Humans have overcome insurmountable odds in the past. There's no reason to believe we can't do it again and crush the climate change problem. It will of course, require sacrifice, money, and hard work. The single most important goal will be to limit the use of fossil fuels such as oil, carbon, and natural gas and replace them with renewable energy sources such as wind generation and solar energy. Here are other ways you can help battle climate change. Cut back

What plant is best for offsetting global warming and combating climate change?

Global warming, or “climate change” is a manmade catastrophe for our planet. It is mainly caused by our emissions of CO2 (carbon dioxide) which is created when we burn fuel in cars and power plants that generate electricity. In short, we pull substances rich with CO2 from deep inside the earth (i.e. oil) and when burned, release CO2 and other gases into the air. The gases act like an insulating blanket around the planet which keeps heat from the Sun inside our atmosphere and thus warming the planet. The production of carbon dioxide and other “greenhouse gases” is further worsened by our purposeful destruction of trees. It is common for entire forests to be cleared for development of housing, shopping centers, and roads and highways. This

NASA’s 20-year satellite-time-lapse of the planet shows a earth breathing as the climate changes

The geeks at NASA released a time-lapse photo revealing how our planet has changed over the past two decades.  The photos were taken from NASA satellites that continuously monitor populations of plant life on land and in the oceans.  The ocean color changes are caused by changing populations of phytoplankton (purple is low population numbers and yellow is high).  If it looks like the planet is breathing - well it is!  NASA stated: That's the Earth, that is it breathing every single day, changing with the seasons, responding to the sun, to the changing winds, ocean currents and temperatures. The space-based view of life allows scientists to monitor crop, forest and fisheries health around the globe. As NASA begins its third decade of measurements, these discoveries point

Grab your bathing suits and sunscreen – ocean levels are rising much faster than we thought

Scientists this week admit that they goofed (again) when estimating the increasing sea levels that result from global warming. If you live in any of the eleven of the fifteen largest cities in the world, you might want to make sure you have a bathing suit handy. Eleven of the fifteen largest cities in the world are located on the coast with lovely oceanside views. Typically these seaside residents take great pride in their sunny beachfront locations, proclaiming with renewed fervor, “Nah, nah, nah, we live by the ocean and enjoy frolicking on the beach all day!” In 100 years however, these cries of joy may change tune and sound more like, “Blub, blub, blub” as the Oceanside residents wonder how the waters rose so fast (and
