Aquarium Algae: Global Warming in Your Tank

Algae growth is a common problem in aquariums, but it can also be a major issue in natural bodies of water, such as lakes and oceans. While the causes of algae growth in these two environments may differ, they both have negative impacts on the ecosystem and require management strategies to prevent excessive growth. This article will compare and contrast the conditions that cause aquarium algae and those that cause algae blooms from climate change, including their similarities and differences, causes, controversies, and solutions.

Aquarium Algae: A Microcosm

Algae growth in aquariums is a common problem that can be caused by various factors, including:

1. Overfeeding: Overfeeding fish can lead to an excessive accumulation of nutrients in the water, which can promote algae growth.

2. Poor water quality: Poor water quality, such as high levels of ammonia and nitrate, can also promote algae growth.

3. Lighting: Algae require light to grow, so if an aquarium is exposed to too much light or light for too long, it can promote algae growth.

4. Lack of water flow: Algae require nutrients to grow, and without sufficient water flow, nutrients can accumulate in certain areas, promoting algae growth.

Aquarium algae can be controlled by taking measures to reduce the factors that promote growth. For example, reducing feeding, improving water quality, reducing light exposure, and increasing water flow can help prevent excessive algae growth.

Climate Change

Climate change has been a topic of discussion over the last few decades. It refers to changes in Earth's weather patterns, including temperature, precipitation, and more. But did you know that the history of climate change dates back to the 1800s?

Let's go back to 1824, when French mathematical physicist Joseph Fourier first proposed that Earth's temperature was affected by the gases in its atmosphere. Math could not account for the temperature of the Earth on Solar radiation alone. In 1859, Irish physicist John Tyndall began researching the heat-absorbing properties of gases, such as carbon dioxide and water vapor.

Then, in 1896, Swedish scientist Svante Arrhenius published a paper in which he calculated that burning coal would increase the amount of carbon dioxide in the atmosphere, leading to global warming.

However, the term "climate change" wasn't widely used until the 1950s. In 1956, American geoscientist M. King Hubbert was among the first to suggest that fossil fuel consumption could lead to climate change.

Then, in the 1960s, scientists began studying ice cores from Antarctica and Greenland, which allowed them to reconstruct Earth's temperature and atmospheric composition over the last 800,000 years. This research confirmed that temperatures were rising and that the concentration of greenhouse gases was increasing.

Over the years, many studies have shown that human activities are the main cause of climate change. In fact, in 2013, the Intergovernmental Panel on Climate Change (IPCC) reported with 95% certainty that human activity is causing global warming.

Despite the overwhelming evidence, climate change remains a controversial topic. Some people argue that climate change is a natural occurrence and that humans have little to no impact on the environment. Others claim that climate change is a hoax or a conspiracy theory created for political reasons.

Climate change is a global issue that threatens the well-being of both humans and the environment. Despite the scientific consensus that humans are the main driver behind global warming, some corporations have actively worked to prevent climate change action.

Their propaganda campaigns have included the promotion of false information and cherry-picking data to deny the existence of climate change. They've also targeted key decision-makers and politicians, using their wealth and influence to sway them away from climate change policy.

This corporate influence on politics has been a major obstacle to climate change action. The US Government even withdrew from the Paris Agreement in 2020, a landmark international treaty to combat global warming, largely due to pressure from fossil fuel industries.

ExxonMobil, one of the largest oil and gas companies in the world, has been accused of intentionally misleading the public about the role of fossil fuels in contributing to climate change. In 2015, an investigation by the Pulitzer Prize-winning news organization InsideClimate News found that Exxon had conducted extensive research on climate change as early as the 1970s.

They found that the company's own scientists had warned top executives about the potentially catastrophic consequences of burning fossil fuels, including rising sea levels, melting Arctic ice, and more frequent extreme weather events approximately 11 years before climate change came to the forefront. However, instead of acting on this information, Exxon continued to fund climate denial groups and lobby against climate action.

In fact, according to a report by the Union of Concerned Scientists, Exxon spent over $30 million between 1998 and 2014 funding organizations that promoted climate denial. They eventually made their findings available to the "public" in the interest of "transparency" by hiding their documents in basements in the hopes no one would actually go looking…but some people looked.

But why would Exxon do this? The answer is simple: money. Fossil fuel companies like Exxon have a vested interest in maintaining the status quo and protecting their profits, even if it means sacrificing the long-term health of the planet.

Exxon's efforts to deceive the public about climate change have had far-reaching consequences. They have delayed urgent action to reduce greenhouse gas emissions, contributed to the loss of biodiversity, and put the lives and livelihoods of millions of people at risk.

The consequences of this inaction are already being felt, with more frequent and severe weather events, rising sea levels, and the destruction of ecosystems. These effects disproportionately impact low-income communities, Indigenous peoples, and communities of color who are the most vulnerable to climate change.

But there is still hope. Grassroots movements, led by activists like Greta Thunberg and the Sunrise Movement, have successfully campaigned for climate change action. And consumers can also make a difference by supporting sustainable companies and divesting from fossil fuel industries.

In recent years, climate change has become a hot-button issue in politics, with some governments refusing to acknowledge its existence or combat its effects. But the scientific consensus is clear: climate change is happening, and we need to take action to mitigate its effects.

Climate Change and HABs

Algae blooms from climate change, also known as harmful algal blooms (HABs), are a growing concern in natural bodies of water. HABs are caused by a combination of factors, including:

1. Warmer water temperatures: Climate change has led to warmer water temperatures, which can promote algae growth.

2. Changes in precipitation: Changes in precipitation patterns, such as increased rainfall or drought, can alter the nutrient levels in water bodies and promote algae growth.

3. Nutrient pollution: Nutrient pollution from agricultural runoff, sewage, and other human activities can promote algae growth.

4. Ocean acidification: Climate change is also causing the ocean to become more acidic, which can negatively impact marine organisms, including those that compete with algae for nutrients.

HABs can have negative impacts on ecosystems and human health, including fish kills, oxygen depletion, and toxic effects on humans and wildlife.

So What Can We Do About It?

The causes of algae blooms from climate change are complex and often controversial. One major controversy is the role of nutrient pollution in promoting HABs. While some studies have shown that nutrient pollution is a significant factor in HABs, others have argued that climate change and warmer water temperatures are the primary drivers.

There are several solutions to prevent or manage HABs, including:

1. Reducing nutrient pollution: This can be achieved by reducing agricultural runoff, improving sewage treatment, and reducing the use of fertilizers and other chemicals.

2. Monitoring and predicting HABs: Monitoring programs can be established to track the growth of HABs and predict when they may occur, allowing for early warning and management strategies.

3. Developing mitigation strategies: Mitigation strategies, such as the use of algaecides, can be developed to manage HABs when they occur.

In conclusion, while algae growth in aquariums and harmful algal blooms from climate change have different causes and impacts, they both require management strategies to prevent excessive growth. By understanding the causes and impacts of these blooms, researchers and managers can develop effective strategies to prevent and manage them, reducing their negative impacts on ecosystems and human health.
