Although global temperatures fluctuate naturally, over the past 50 years the average global temperature has augmented at its fastest rate in recorded history. The emission of greenhouse gasses such as Carbon Dioxide (CO2), Nitrous Oxide (N2O) and Methane (CH4) render the Earth’s atmosphere more transparent to visible radiation from the sun than to infrared radiation … Read more
Climate change is a global concern that affects many species and ecosystems; polar bears are essentially the poster child for species impacted by Earth’s warming temperatures. “Earth’s 2015 surface temperatures were the warmest since modern record keeping began in 1880,” according to independent analyses by NASA and the National Oceanic and Atmospheric Administration. Polar bears … Read more
There are many common arguments used by climate change skeptics. There is both human caused and non-human caused climate changes. Global warming may be a hoax or due to changes in nature. Natural changes such as sunspots and orbital change has had an effect on climate. Sun spots have been investigated since the 1800’s. Research … Read more
The ocean is home to many of the most prominent, yet commonly looked over, indicators of anthropogenic climate change present in society today. Often these indicators are in connection with many other obvious, more recognized factors such as the emission of greenhouse gases or the drastic change in global temperatures. More specifically, ocean acidity can … Read more
Climate change and pollution have immensely increased every day and this rise is beginning to take a serious toll on Australia’s environment and wildlife. Modern Australians habits, lifestyles and attitudes have caused severe problems on wildlife and nature that will continue getting more serious unless action is taken. This essay will be discussing how climate … Read more
The issue of conservation has been discussed, dissected, and debated over for centuries by people who understand that endlessly destroying habitats and over-hunting species inevitably leads to permanent damage that affects everyone. Sure, there have been major milestones in the efforts to stabilize natural habitats such as Theodore Roosevelt’s actions in creating national parks and … Read more
Collecting Photosynthetic Rates in Spinach (Spinacia oleracea) Introduction: The purpose of this study was to see which light color would cause the spinach sample to photosynthesize the most within the given time. In order to understand photosynthesis, we need to know that chloroplasts absorb light energy from the sun, the plant then takes that energy … Read more
Human activity has contributed to the deterioration of the earth as global warming and climate change have proven to be a prevalent issue within our society. One of human’s biggest contribution to climate change is animal agriculture. Animal agriculture is the largest user of land and is the number one contributor to the emission of … Read more
All living organisms respire and they need energy to carry out their life processes in order for organisms to survive and produce. The gases involved in cellular respiration is oxygen and carbon dioxide. The process of cellular respiration is releasing energy from sugars using oxygen and the product is carbon dioxide and water and in … Read more
Waveform capnography to today’s paramedic is what it felt like with the invention of the washing machine becoming available to generations of people who grew up using a wash board. Now that people have a machine to do the work for them, they cannot imagine going back to hand washing. The same holds true for … Read more
The topic of my essay is extremely significant to the time we are in now to understand the greenhouse effect and global warming issues that are talked by geologists. Bill McKibben has in his article ‘Sounding the Alarm Bell, explained the reasons for spreading awareness on global warming. Global warming has been a big issue … Read more
Introduction During the final week of January 2009, Victoria endured one of its most severe and prolonged heatwaves. The temperature in Melbourne was above 43°C for three consecutive days for the first time since records had been kept. Saturday 7 February was forecast to reach temperatures in the low 40s, accompanied by strong winds, igniting … Read more
Ocean acidification is the continuous reduction of the ocean’s pH, carbonate ion concentration, and saturation states of biological calcium carbonate minerals. Ocean acidification is caused by the uptake of carbon dioxide from the atmosphere. According to “Ocean Acidification: The Other CO2 Problem,” after the industrial revolution, carbon dioxide levels in the atmosphere has increased nearly … Read more
The melting of the polar ice caps and glaciers produce negative effects on environment and humans, including habitat destruction and disruption of animal lives. The ice glaciers are slowly melting over time resulting a rise of sea-level. The cause for the sea-level increasing is global warming. The planet’s heat is increasing slowly over time creating … Read more
The main factors of this article called “Methanol–the fuel in Waiting” explains how Methanol could both have positive and negative effects in the environment and the economy. The article discusses how methanol could be another alternative to gasoline and it is a made from natural gas, which makes it easier to make and use. Methanol … Read more
