Along with its anxiety-inducing effects, climate change also offers an interesting opportunity to consider fascinating, interconnected processes on Earth. The smallest to the largest components of the planet – from bacteria to volcanoes – all somehow feel the effects of a changing climate. Here are six of the most unexpected ways climate change impacts Earth
Desert bacteria dies
Desert soil may appear desolate and void of life, but it actually teems with bacteria. Bacterial colonies can grow so thick that they form sturdy layers called biocrusts that stabilize soil against erosion. A study of these biocrusts across deserts in the United States showed that different types of desert bacteria thrive in different temperature regimes. Some prefer the sweltering heat of Arizona and New Mexico, while others fare better in the cooler climate of southern Oregon and Utah. As temperatures become more erratic with climate change, desert bacteria may struggle to adapt, leaving desert soil more prone to erosion.
Volcanic eruptions explode
As glacial meltwater floods into oceans and the global sea level rises with climate change, the distribution of weight on the Earth’s crust will shift from land to sea. This shift in weight distribution could cause volcanoes to erupt more often, some studies suggest. Evidence of this phenomenon has been detected in the rock record, with remnants of more abundant volcanic eruptions correlating with periods of glacial melt at several points in Earth history. Humans in the 21st century probably won’t experience this shift, however, since this effect seems to lag by up to about 2,500 years.
The Essay on Climate Changes Towards Global Warming
Climate Changes towards Global Warming For centuries human race has had a very strong detrimental influence upon natural environment. One of the largest areas of environmental concern is human-induced climate change. Through technological advancements human beings have accelerated earth on its course towards destruction. Here we clearly see that current state of development of the technology and ...
Oceans darken
Climate change will increase precipitation in some regions of the world, resulting in stronger-flowing rivers. Stronger river currents stir up more silt and debris, which all eventually flows into the ocean and makes the ocean more opaque. Regions along the coast of Norway have already experienced increasingly darker and murkier ocean water with increased precipitation and snow melt in recent decades. Some researchers have speculated that the murkiness is responsible for changes in regional ecosystems, including a spike in jellyfish populations.
Allergies worsen
As climate change causes springtime to spring out earlier in the year, sneeze-inducing pollen will ride the airwaves that much earlier in the year as well. This will increase the overall pollen load each year, and could make people’s allergies worse. Some temperature and precipitation models have shown that pollen levels could more than double by the year 2040.
Ant invasions slow
Pheidole megacephala, also known as the big-headed ant, is one of the top 100 most invasive species on Earth. Hoards of these insects thrive in South America, Australia and Africa, and their voracious populations spread rapidly. As invasive animals, they steal habitat and resources from native species, disrupting regional ecosystems and jeopardizing biodiversity. They have even been known to hunt bird hatchlings. Researchers have estimated that 18.5 percent of the land on Earth currently supports the big-headed ant. But as temperatures shift in the coming decades, the habitat range of these cold-blooded animals will likely shrink substantially. Some climate models suggest that the ant’s range will decrease by one-fifth by the year 2080. How native insects will respond to these changes, however, remains unclear.
Sunlight floods polar seafloor
As sea ice melts, more sunlight will bathe shallow coastal regions around the poles. Seafloor communities of worms, sponges, and other invertebrates accustomed to existing in darkness will begin to experience longer periods of sunlight each summer. Recent research has shown that this shift could significantly alter these communities, by allowing seaweeds and other marine plant-life to smother invertebrates. This transition from invertebrate-dominated communities to algae-dominated communities has already been observed in pockets of both the Arctic and Antarctic coastlines, and could significantly decrease biodiversity in these regions.

The Essay on How did WWII change America and the World
The World War II remains the bloodiest and deadliest crisis in world history. It involved the best ever battle lines, enormous armed forces, along with the most destructive weapons in the history of the world (Martel 245). The worldwide disagreement that was regarded as or labelled World War II emanated from the 1930s great depression, a turmoil that undermined, destabilized and weakened ...
Over 100 years ago, people worldwide began burning more coal and oil for homes, factories, and transportation. Burning these fossil fuels releases carbon dioxide and other greenhouse gases into the atmosphere. These added greenhouses gases have caused Earth to warm more quickly than it has in the past. How much warming has happened? Scientists from around the world with the Intergovernmental Panel on Climate Change (IPCC) tell us that during the past 100 years, the world’s surface air temperature increased an average of 0.6° Celsius (1.1°F).
This may not sound like very much change, but even one degree can affect the Earth. Below are some effects of climate change that we see happening now. Sea level is rising. During the 20th century, sea level rose about 15 cm (6 inches) due to melting glacier ice and expansion of warmer seawater.
Models predict that sea level may rise as much as 59 cm (23 inches) during the 21st Century, threatening coastal communities, wetlands, and coral reefs. Arctic sea ice is melting. The summer thickness of sea ice is about half of what it was in 1950. Melting ice may lead to changes in ocean circulation. Plus melting sea ice is speeding up warming in the Arctic. Glaciers and permafrost are melting. Over the past 100 years, mountain glaciers in all areas of the world have decreased in size and so has the amount of permafrost in the Arctic. Greenland’s ice sheet is melting faster too. Sea-surface temperatures are warming. Warmer waters in the shallow oceans have contributed to the death of about a quarter of the world’s coral reefs in the last few decades. Many of the coral animals died after weakened by bleaching, a process tied to warmed waters.
The Essay on Investigation into temperature change
Introduction. The following is an experiment into temperature change in an exothermic reaction taking place between Sodium hydroxide (NaOH) and Hydrochloric acid (HCl) and also how the concentration of the acid will vary these results. The characteristics of the reaction feature a neutralisation, an energy change (shown as a temperature change) that is usually exothermic (gives out heat). The ...
The temperatures of large lakes are warming. The temperatures of large lakes world-wide have risen dramatically. Temperature rises have increased algal blooms in lakes, favor invasive species, increase stratification in lakes and lower lake levels. Heavier rainfall cause flooding in many regions. Warmer temperatures have led to more intense rainfall events in some areas. This can cause flooding. Extreme drought is increasing. Higher temperatures cause a higher rate of evaporation and more drought in some areas of the world. Crops are withering. Increased temperatures and extreme drought are causing a decline in crop productivity around the world. Decreased crop productivity can mean food shortages which have many social implications. Ecosystems are changing. As temperatures warm, species may either move to a cooler habitat or die.
Species that are particularly vulnerable include endangered species, coral reefs, and polar animals. Warming has also caused changes in the timing of spring events and the length of the growing season. Hurricanes have changed in frequency and strength. There is evidence that the number of intense hurricanes has increased in the Atlantic since 1970. Scientists continue to study whether climate is the cause. More frequent heat waves. It is likely that heat waves have become more common in more areas of the world. Warmer temperatures affect human health. There have been more deaths due to heat waves and more allergy attacks as the pollen season grows longer. There have also been some changes in the ranges of animals that carry disease like mosquitoes. Seawater is becoming more acidic. Carbon dioxide dissolving into the oceans, is making seawater more acidic. There could be impacts on coral reefs and other marine life.
