10 Ways Humans Impact the Environment
We as humans have become dependent on luxuries such as cars, houses, and even our cell phones. But what does our love for manufactured metallic and plastic goods do to the environment? Human activity can be directly attributed to the cause of hundreds of extinctions in the last two centuries, versus the millions of years that extinctions naturally occur.

Sea animals are more vulnerable to warming than are land ones
Ecologists, conservationists and policymakers are struggling to understand how much of a threat climate change poses to Earth’s biodiversity — estimated to be some 3 million to 100 million species1 — and what to do about that threat. Knowing whether terrestrial or marine species are more vulnerable to climate change, as well as how the risks vary with latitude, could inform the deployment of limited conservation resources, nationally and globally. Writing in Nature, Pinsky et al.2 combine robust experimental data with a careful model-based approach to compare the vulnerability of biodiversity to warming across latitudes on land and in the ocean. There is contradictory evidence about the relative vulnerability to warming of land and ocean animals.

AP Environmental Science Test: Pollution
The correct answer is (C). Polychlorinated biphenyls, or PCBs, are a group of industrial compounds that have caused many environmental problems. Until 1979 they were manufactured in plastics and insulating electrical transformers. Even though they are not longer manufactured, they are still present in the environment because of their long-term persistence.
The Greenhouse Effect - Causes of the Greenhouse effect
What is the Green house effect ? The Earth is kept warm by it’s atmosphere, which acts rather like a woolly coat – without it, the average surface temperature would be about -18 degrees Centigrade. Heat from the sun passes through the atmosphere, warming it up, and most of it warms the surface of the planet. As the Earth warms up, it emits heat in the form of infra-red radiation – much like a hot pan emits heat even after it’s taken away from the cooker.

Evidence for climate change
This page has information on what climate change is, how we know it is happening, and what this might mean for the future. What is climate change? Earth’s atmosphere is made up of oxygen, a large amount of nitrogen and a small percentage of greenhouse gases, such as carbon dioxide and methane.

Climate Change
The term "climate change" refers to a rise in the average global temperature due to an increase in the concentration of atmospheric greenhouse gases, resulting in numerous climatic shifts and impacts around the globe. The term “global warming” is also used, although it is important to recognize that the increase in temperature is a global average and individual locations will experience varied temperature and precipitation changes. Several gases, such as carbon dioxide (CO2) and methane (CH4), exist naturally in the atmosphere and contribute to the warming of the Earth's surface by trapping heat from the sun, in what is known as the greenhouse effect.
Is wood a green source of energy? Scientists are divided
It took half a century for an acorn to grow into the 20-meter-tall oak tree standing here in a North Carolina hardwood forest near the banks of the Northeast Cape Fear River. But it takes just seconds to turn the oak into fuel for the furnace of a European power plant. A logging machine—a cross between a tank and a one-armed crab—grabs the tree with a metal claw.
Global Warming: 2018 Articles, Facts, Causes & Effects
Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. There is great debate among many people, and sometimes in the news, on whether global warming is real (some call it a hoax). But climate scientists looking at the data and facts agree the planet is warming.While many view the effects of global warming to be more substantial and more rapidly occurring than others do, the scientific consensus on climatic changes related to global warming is that the average temperature of the Earth has risen between 0.4 and 0.8 °C over the past 100 years.

Facts – Climate Change: Vital Signs of the Planet
› en español Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves. Taken as a whole, the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time. Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities.
