Do Scientists Know What Causes Solar Storms?

April 11, 2019

Most of us only think of the sun in passing. On hot afternoons when we hide beneath the shade, or rainy mornings when we wish for a little light, the sun is a subject of discussion. Otherwise, it’s all too easy to forget that our planet survives on the heat from a fiery ball of hot plasma 1.3 million times its size.

With this enormous number in mind, the concept of a “solar storm” is somewhat frightening. After all, the scale of our sun is immense and its power is incredible. It seems probable we’d eventually have to reconcile the fact that we live a very short distance from it, by astronomical standards.

In truth, solar storms aren’t as dangerous as they sound. They’re part of a cycle of high and low activity that repeats every 11 years. This cycle’s “solar maximum,” or peak, occurred between 2013 and 2014. As NASA predicted, we didn’t see any catastrophic solar events like some feared.

So what exactly are “solar storms” and how do they affect the Earth? Do scientists know what causes them? If so, what are the reasons behind this fascinating phenomenon? We’ll answer those questions and others like them by taking a comprehensive look at the many intriguing aspects of solar storms.

Ocean Heat Waves Threaten Marine Wildlife

April 8, 2019

You usually hear on the news about large heat waves that occur over land, but we rarely hear about them happening in the ocean. They do take place, and according to a new study published in Nature Climate Change, they’re becoming more frequent.

The paper, titled Marine Heatwaves Threaten Global Biodiversity and the Provision of Ecosystem Services, says marine heat wave days have increased by more than 54 percent over the last 30 years. These periods of abnormally high water temperatures for a given region not only became more frequent but also began lasting longer over the study period.

These trends, the study’s authors wrote, is consistent with decreasing amounts of marine life. Marine heat waves are another stress on seas that are already facing pollution, overfishing, declining oxygen levels, increasing acidity and other challenges.

World’s First Plastic-Free Flight Paving the Way for Green Aviation

January 28, 2019

The aviation industry’s relationship with sustainability is somewhat complicated. Though industry leaders have acknowledged the environmental impact of air travel, progress is slow, and the damage is considerable. As of 2017, aviation was responsible for 11 percent of transportation-related emissions in the United States.

So how can today’s airlines affect change? Portuguese carrier Hi Fly has proven small changes are the best place to start, taking a significant step toward green aviation with the world’s first plastic-free flight. On December 26, they made a trip between Lisbon and Brazil without any single-use plastic items on board.

In this article, we’ll explore the implications of this simple, but no less important example of sustainability in air travel. As we examine the efforts of Hi Fly and carriers like them, we’ll show how the aviation industry is transitioning toward eco-friendly practices.

December 31, 2018
environmental news

The future of the planet isn’t often a positive topic of discussion, and it’s admittedly easy to see the negatives. As fluctuating temperatures, unseasonable weather and natural disasters such as hurricanes and forest fires grow more common, it seems our current course is taking us toward even greater environmental disaster.

In truth, there’s still time to change the future’s trajectory, and politicians and entrepreneurs have made incredible progress in the renewable energy sector and other areas of restoration and conservation. 2018 was a pivotal year for the planet, and we’ll recap some important environmental news everyone should know about.

Reliance on fossil fuel paints a grim picture of the future. Heavy pollution and poor air quality, tainted groundwater and ravaged ecosystems comprise a landscape where nothing grows — the Earth salted without hope of restoration. Given the current political climate, this is a pressing threat.

The optimistic men and women at GRID Alternatives Mid-Atlantic picture the future differently. They view the future as one of long-term sustainable energy, using affordable alternatives to conventional methods to preserve the environment while enjoying the same level of comfort and convenience.

In their picture of the future, the air is clean, the groundwater is clear and wildlife receives the respect it deserves. The grass grows a little greener, and harmony exists between the natural and artificial. So how is GRID working toward making this dream a reality?

Have you recently booked an Uber trip? There’s a chance the driver’s vehicle was an electric car, but Uber still has progress to make in that area.

To put things in perspective, 4 billion people took Uber trips in 2017, but only 4 million of those were in Uber electric cars.

The relatively few drivers who have electric vehicles (EVs) and work for Uber face challenges such as having difficulty finding charging points. In addition, the time it takes to recharge the cars interferes with time they could spend earning money.

In Light of National Aviation Day, How Can We Make Flight Greener?

August 16, 2018
National Aviation Day

On August 19, you can celebrate National Aviation Day. Perhaps you’ll do that by taking a flight to a place you’ve always wanted to explore, making good on your goal of signing up for flight lessons or just spending time feeling thankful we have that method of transportation at our disposal.

But, despite all the conveniences and innovations traveling by plane brings, it’s not kind to the environment. So, what can we do to start changing that bit by bit?
