Why do people believe global warming is occurring on Earth? lw19267 https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331373667 There is ice melting rapidly throughout the world. According to NASA, the planet's average surface temperature has risen about 1.62 degrees Fahrenheit since the late 19th century. 

The main cause of this is the large increase of carbon dioxide and other human-made emissions.]]> 2019-02-14 16:18:23 UTC https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331373667 2. Why are some people skeptical of global warming? lw19267 https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331374197 The rising sea levels may not have anything to do with climate change at all. Global sea level rise is simultaneously one of the most certain and uncertain impacts of climate change. ]]> 2019-02-14 16:19:09 UTC https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331374197 3. Where is the fastest warming of Earth's atmosphere occurring? lw19267 https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331374408 The Great Barrier Reef in Australia due to the coral mortality rate is above 50 percent.]]> 2019-02-14 16:19:30 UTC https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331374408 4. Compare global population numbers with rising carbon dioxide levels. Are they related? lw19267 https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331375286 "Population causes CO2. T The more people there are on our planet, the more CO2-generating activities there will be, such as electrical power generation, industrial activity, automobiles, cooking fires, etc."

"CO2 causes population. Population growth in these regions is dependent to a large extent on the food supply, and as we know, crop yields increase with CO2 levels. The greater the food supply, the longer people will live."

Where will they go? lw19267 https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331376596 Environmental refugees are a subset of environmental migrants who were forced to flee due to sudden changes to the environment and climate. ]]> 2019-02-14 16:23:04 UTC https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331376596 7. In 50 years, would we be fleeing our area or accepting environmental refugees into our area? lw19267 https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331377573 Warmer global temperatures will play out differently in different regions of the world, but I think we will be accepting more refugees here because climate will change more in the northern and southern areas of the world.]]> 2019-02-14 16:24:37 UTC https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331377573 8. Does gasoline that cars need to operate and function contribute to Earth's greenhouse effect? lw19267 https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331378306 Materials like gasoline for our cars and burning gas, coal, oil for our homes release greenhouse gases. These include CO2, methane, and water vapor. 

Heat gets trapped and the earth’s temperature rises when greenhouse gases build up. In order to decrease the amount of gases in the atmosphere, people can try to use less energy.]]> 2019-02-14 16:25:42 UTC https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331378306 9. How does an increasing consumption of and demand for meat in a human's diet relate to carbon emissions? lw19267 https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331378695 Meat can be obtained through different farmings, livestock production, agriculture hunting, and fishing.

All agricultural practices have been found to have a variety of effects on the environment. Some of the environmental effects that have been associated with meat production are pollution through fossil fuel usage, animal methane, effluent waste, and water and land consumption.]]> 2019-02-14 16:26:14 UTC https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331378695 10. How does an increasing consumption of and demand for fish in a human's diet relate to carbon emissions? lw19267 https://padlet.com/lisle202/qxr3k8ol4dfv/wish/331379395 Due to people littering, pollution has increased more than ever. The fish we eat are exposed to toxic chemicals in the bodies of waters they live in. Mercury has shown up at disturbingly high levels in many fish
Sometimes fish even get chemicals from the plastic debris they ingest.

What can ice cores tell us about the history of Earth's climate over time? How far back in time can ice cores provide info? lw19267 https://padlet.com/lisle202/qxr3k8ol4dfv/wish/332749273 They allow us to go back in time to sample accumulation, air temperature and air chemistry. 
Ice core records allow us to generate continuous reconstructions of past climate, going back at least 800,000 years.
Scientists can calculate how modern amounts of carbon dioxide and methane compare to those of the past and compare past concentrations of greenhouse gasses to temperature.]]> 2019-02-19 15:50:16 UTC https://padlet.com/lisle202/qxr3k8ol4dfv/wish/332749273 13. How have sea levels fluctuated over the last thousand years? Is this driven by natural circumstances or is this caused by humans? lw19267 https://padlet.com/lisle202/qxr3k8ol4dfv/wish/332749411 "Between 1900 and 1990 studies show that sea level rose between 1.2mm and 1.7mm per year on average. By 2000, that rate had increased to about 3.2mm per year. Sea levels are expected to rise even more quickly by the end of the century."

Scientists have said how sea levels have increased over time mainly due to climate change. They also agree that changes in climate are mainly caused by humans and their activities.

Can it be used to irrigate crops for 7 billion Earthlings? lw19267 https://padlet.com/lisle202/qxr3k8ol4dfv/wish/333223665 According to ScientificAmerican.com,  "Less moisture is trapped in ice sheets, so more is found in liquid form.
When ice pieces fall off landmasses, such as Antarctica or Greenland, and into the ocean, the ice melts even faster."

According to water.usgs.gov, "Seawater is toxic because your body fails eventually when it has to try to get rid of the salt that comes from sea water. Your body normally gets rid of excess salt by having the kidneys produce urine, but it needs freshwater to dilute the salt in your body for the kidneys to work properly."

Why is there less heat escaping into space? lw19267 https://padlet.com/lisle202/qxr3k8ol4dfv/wish/333692611 The surface of the Earth is absorbing most of the sun's heat, but it gives infrared radiation to space.]]> 2019-02-21 15:54:34 UTC https://padlet.com/lisle202/qxr3k8ol4dfv/wish/333692611 18. How does CO2 trap infrared radiation on Earth? lw19267 https://padlet.com/lisle202/qxr3k8ol4dfv/wish/333712703 CO2 molecules vibrate in ways that simpler nitrogen and oxygen molecules cannot, which allows CO2 molecules to capture the IR photons. Greenhouse gases and the greenhouse effect play an important role in Earth's climate.]]> 2019-02-21 16:25:57 UTC https://padlet.com/lisle202/qxr3k8ol4dfv/wish/333712703 19. Clouds (water vapor) are considered a greenhouse gas. How can cloud coverage both complicate the heating of Earth and also help alleviate the heating of Earth? lw19267 https://padlet.com/lisle202/qxr3k8ol4dfv/wish/333712937 Clouds cool the Earth by reflecting incoming sunlight. The tiny drops or ice particles in clouds scatter between 20 and 90 percent of the sunlight that strikes them.

Clouds warm the Earth by absorbing infrared radiation emitted from the surface and reradiating it back down. The process traps heat like a blanket and slows the rate at which the surface can cool.
