Have you ever heard of the butterfly effect? It's the idea that small, seemingly insignificant events can have a big impact on the world around us. This concept also applies to our climate. Small changes in weather patterns can lead to big impacts on our planet. One example of this is the El Niño Southern Oscillation (ENSO). ENSO is a natural climate pattern that occurs when the ocean and atmosphere interact in the tropical Pacific. It can cause droughts, floods, and other extreme weather events around the world. In fact, the 1997-1998 El Niño caused $45 billion in damages and over 20,000 deaths. But it's not just natural events that can impact our climate. Human activities like burning fossil fuels and deforestation also contribute to changes in our weather and climate. The emissions from these activities trap heat in the atmosphere, leading to global warming and climate change. One of the leading academics in the field of climate science is Dr. James Hansen. He was one of the first scientists to warn the public about the dangers of climate change back in the 1980s. He has continued to be an advocate for action on climate change and has published numerous papers on the topic. Another important concept in climate science is the feedback loop. A feedback loop occurs when a change in one part of the climate system causes a change in another part of the system, which in turn can cause more changes in the original part. This can lead to amplification or damping of the original change. So what can we do about the butterfly effect on our climate? It starts with small actions we can take in our daily lives, like reducing our carbon footprint and supporting clean energy. But it also requires larger actions from governments and businesses to reduce emissions and invest in renewable energy. Remember, small actions can have a big impact on our climate. So let's work together to make a difference.
Carbon dioxide (CO2) is one of the most dangerous greenhouse gases that is causing global warming and climate change. It stays in the atmosphere for much longer than other gases such as methane, which only stays in the atmosphere for about 12 years, while CO2 can remain in the atmosphere for thousands of years. Leading climate scientists such as Dr. James Hansen agree that increasing levels of CO2 in the atmosphere are causing global temperatures to rise, leading to melting glaciers, rising sea levels, and more frequent and intense natural disasters such as hurricanes, droughts, and wildfires. Decarbonization is the process of reducing the carbon footprint of our economy by transitioning from fossil fuels to cleaner, renewable energy sources such as wind and solar. This is crucial in order to prevent dangerous levels of global warming and ensure a sustainable future for generations to come. One promising innovation in the field of decarbonization is carbon capture and storage (CCS), which involves capturing CO2 emissions from power plants and industrial processes and storing them underground. Another is the development of electric vehicles, which produce zero emissions and have the potential to greatly reduce our reliance on fossil fuels. Leading academics in the field, such as Dr. David McCollum, have emphasized the importance of decarbonization in limiting global temperature rise to below 2 degrees Celsius, a threshold beyond which the impacts of climate change would become catastrophic and irreversible.

Geologists can find employment in a wide range of public and private sector organizations, including the US Geological Survey, ExxonMobil, the National Park Service, the United Nations, and many more.
Mining has been a crucial part of human civilization for centuries, providing us with the resources we need to build, create and thrive. But with this extraction comes consequences, particularly in the form of mine tailings. Mine tailings are the waste materials left over after the ore has been extracted, and they can have significant impacts on the environment, particularly with regards to climate change. To understand the impact of mine tailings, it's important to first understand the science behind mining. When ore is extracted, the minerals are separated from the rest of the material, leaving behind a mixture of minerals, water, and other substances. This mixture is called tailings, and it can contain harmful chemicals, such as heavy metals, that can leach into the environment. Leading academics in the field, such as Dr. Sara Colombo and Dr. Jian Kang, have studied the environmental impact of mine tailings and have found that they can lead to soil and water pollution, as well as contribute to greenhouse gas emissions. For example, Dr. Colombo's research has shown that tailings dams can release large amounts of methane, a potent greenhouse gas, into the atmosphere. These impacts are a concern for many communities, as well as for the planet as a whole. But despite this, there is hope for a more sustainable future. Researchers like Dr. Jian Kang are working to develop new technologies that can reduce the environmental impact of mine tailings, such as using them as a source of energy instead of just waste.

Traditional diamond mining is a billion-dollar industry with significant environmental impact, releasing large amounts of carbon emissions and causing damage to local ecosystems worldwide. However, carbon-negative diamonds are produced through a process that actually captures carbon emissions from the atmosphere, making them a much more sustainable alternative for the jewellery industry. Aether Diamonds, a major player in this industry, uses direct-capture technology for diamond production in a two-step process. First, a reactor is used to extract the carbon dioxide from the atmosphere, while this raw carbon material is placed in another reactor that kickstarts the diamond-growing process. The resulting diamonds are visually indistinguishable from traditionally-mined diamonds and have the same physical and chemical properties, but have been produced with a much lower carbon footprint. This ingenious solution reimagines existing carbon-capture services, where firms are paid by various multinational corporations to capture their carbon emissions, by recycling this extracted carbon dioxide for an inventive purpose. By eliminating 20 tons of carbon dioxide for every 1-carat diamond produced, each diamond can actively contribute to carbon emission reduction efforts. Beyond the jewelry industry, researchers have used a similar process to produce important industrial materials from carbon. Dr. Stuart Licht, a chemistry professor at George Washington University, is a leading academic in this field of renewable technology. His patented technology, the Solar Thermal Electrochemical Photo (STEP) energy conversion, captures carbon dioxide using renewable solar energy to create carbon nanofibers. This material provides a lighter and stronger alternative to metals like steel, and is used in luxury sports cars, aeroplanes like the Boeing Dreamliner, and high-end athletic equipment. These creative uses of carbon-capture technology offer a promising future, especially with carbon-negative diamonds for the sustainable fashion industry. Beyond that, these diamonds also offer a more ethical alternative — sustainable diamond production avoids the international human rights abuses and violence that traditional diamond mining has been linked to. All in all, carbon-negative diamonds have the potential to revolutionize the sustainable fashion industry and beyond, and are a fascinating scientific innovation with many exciting future implications.

Did you know that human activity can cause earthquakes? In fact, they're becoming more common due to drilling, mining, and other subsurface activities. For example, a 5.1 magnitude earthquake in Spain in 2011 was caused by farmers using underground water for irrigation, which caused a shift in the fault line. The oil and gas industry, geothermal power developers, and dam builders have also caused man-made earthquakes. Learning about the science behind earthquakes is not only intellectually fascinating, but it can also help us understand how to avoid making the problem worse. Earthquakes are one of the most catastrophic natural disasters, and there is currently no way to predict when they will strike. As students, we can take an active role in learning about the impact of human activity on the environment and how we can make a positive difference.
