Who was the first person to propose the climate zone?
Eighty years ago, Guy Callendar built the first climate change model to predict the effects of greenhouse gases.
What is global bal warming?
“Global warming is a gradual increase in the earth’s temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
How does a changing climate impact the ocean food chain?
“Warmer temperatures can cause metabolic rates to accelerate faster than growth rates, which reduces the energy available to predators in the next level up the food web.”
What would happen to plankton if the oceans heated up another 2 degrees?
If total global heating increases to 2–3 degrees Celsius, these figures could rise to nearly 25%. Saline water is heavier and moves deeper into the ocean. This reduces the nutrients available at the ocean surface, which once again harms the phytoplankton population.
What happens if the ocean food chain collapses?
Less productive marine plants will mean less energy is passed to plant-eaters, which will slowly dwindle the population of these grazers for predators to eat up the line. This could lead to a cascade of negative effects for a great many species.
How did Greta Thunberg learn about climate change?
Thunberg received numerous invitations to speak about climate change. She gave speeches at the World Economic Forum in Davos, Switzerland, and at the European Parliament as well as in front of the legislatures of Italy, France, the United Kingdom, and the United States.
Who is the founder of climate?
In 1896 Svante Arrhenius calculated the effect of a doubling atmospheric carbon dioxide to be an increase in surface temperatures of 5–6 degrees Celsius. This 1902 article attributes to Svante Arrhenius a theory that coal combustion could eventually lead to human extinction.
Who was the founder of climate change?
Svante Arrhenius (1859-1927) was a Swedish scientist that was the first to claim in 1896 that fossil fuel combustion may eventually result in enhanced global warming. He proposed a relation between atmospheric carbon dioxide concentrations and temperature.
How will the climate warm over the next 100 years?
State-of-the-art climate models suggest that this will result in an increase of about 3.5oF in global temperatures over the next century.
What would happen if all plankton died?
Plankton are the base of the marine food web, without them all larger organisms will probably die. No plankton=no fish= no food for millions of people. Without ocean life millions (if not billions) of people will start to starve.
