Understanding Algal Calcification May Help Climate Change

Panayiota Siskos ’23 Increased interest in quantifying marine ecosystems’ ability to trap carbon and offset it from the atmosphere has led to efforts for this process to be harnessed in global carbon offset schemes. Early studies to this end were focused on organic carbon, with an underlying belief that marine ecosystems were believed to only have photosynthesizing plants. In time, it was discovered that ecosystems … Continue reading Understanding Algal Calcification May Help Climate Change

Tree Diversity and Climate Change

By Raymond Cheung ‘22 Since trees can absorb greenhouse gases through photosynthesis, reforestation efforts are becoming a more crucial way to combat climate change. However, new research suggests that the number of tree species planted is as essential as the quantity. A recent study conducted by Yuanyuan Huang and more than sixty scientists from China, Switzerland, and Germany analyzed over 150,000 trees planted in the … Continue reading Tree Diversity and Climate Change

The Effects Of Climate Change On The Macroporosity Of Soil

By Kavindra Sahabir ‘21 Climate change, in addition to contributing to rising temperatures around the globe, may also be affecting the availability of water and production of food. Soil macropores are, at their most basic level, holes in soil that act as natural drains of water due to gravity. They affect factors such as nutrient transport for plants and water runoff in fields, which in … Continue reading The Effects Of Climate Change On The Macroporosity Of Soil

Determining the History of the Earth’s Orbit

By Anna Tarasova‘19 Milankovitch cycles are an established part of geological theory that describes the long-term effects of changes in the movements of the Earth on its climate. Specifically, these cycles describe the relative positions of planetary bodies and the resulting exposure of the Earth to sunlight. However, Milankovitch cycles are only reliable in describing climate change over limited time periods within the last 50 … Continue reading Determining the History of the Earth’s Orbit

Mobilizing Courts in the Fight Against Climate Change

By Meenu Johnkutty ‘21 Attempts to amend national attitudes towards climate change have been at the forefront of the climate change movement. The recent movement to involve the national court system may prove effective in mitigating the future effects of climate change, especially in regard to coal pollution and the risk it poses to public health. A study conducted by Dr. Sabrina McCormick from George … Continue reading Mobilizing Courts in the Fight Against Climate Change

Graphitic Electro-catalytic Fuel Cells

By Meenu Johnkutty ‘21 For decades, climate scientists have touted wind, solar, and nuclear energy as alternatives to fossil fuels, which, due to their affordability, nonetheless remain an attractive avenue for big oil companies. Recent studies have demonstrated that fuel cells, electrochemical cells that convert hydrogen into electricity, have potential to replace current energy sources. These novel forms of energy are characterized by high efficiency, … Continue reading Graphitic Electro-catalytic Fuel Cells

Weight of Rising Sea Levels Causes Ocean Floor to Sink

By Marcia-Ruth Ndege ’21 Over the past few decades, global climate change has become a widely debated issue. Its believability, however, is no longer relevant as we are living through its effects across the globe; whether it be through melting glaciers in the Arctic, droughts and wildfires in California, or decreased rainfall in Ethiopia, the effects of climate change are prominent and devastating. A new … Continue reading Weight of Rising Sea Levels Causes Ocean Floor to Sink

Positive Feedback Loop Implicated in Methane Emissions from Aquatic Environments

By Meenu Johnkutty ‘21 Scientists have long forewarned of the detrimental effects of climate change on the planet. Rising global temperatures coupled with the lack of due diligence in handling the environmental crisis have scores of ecologists worried about the many fragile ecosystems on the brink of a biodiversity crisis. A recent study conducted by researchers from Radboud University Nijmegen in the Netherlands provides new … Continue reading Positive Feedback Loop Implicated in Methane Emissions from Aquatic Environments

Using Biointelligence to Combat the Effects of Climate Change on Coffee Agriculture

By Meenu Johnkutty ’21 For a number of years, many scientific models predicted a decline in bee populations due to the increase in the use of bee-killing pesticides in industrial agriculture. As global temperatures continue to rise, it is expected that biodiversity among bees will also continue to decrease, jeopardizing the pollination of many crops. As pollinators are essential to the pollination of the coffea … Continue reading Using Biointelligence to Combat the Effects of Climate Change on Coffee Agriculture

Small-Scale Modeling Shows Influences on Climate Change

by Jenna Mallon (’18) Due to their low-latitude location, Mesoamerica and the Caribbean are at particularly high risk of experiencing the effects of climate change. There are currently many global models that show the effects of climate change on a large scale, but fail to take into account the effects that topography and land use have on temperature and precipitation.  This prompted Robert Oglesby, of … Continue reading Small-Scale Modeling Shows Influences on Climate Change
