Describe One Explanation for Why Earth's Climate Is Becoming Warmer

Explain why many scientist think that the earths climate is becoming increasingly warmer. The earth surface is warmer in the northern hemisphere when it issummer there because of the angle of the sun.

The effects of warming are already being seen and will become more extreme as temperature rise.

. We know this warming is largely caused by human activities because the key role that carbon dioxide plays in maintaining Earths natural greenhouse effect has been understood since the mid-1800s. Too many animals are becoming extinct. The think that because greenhouse gases trap heat near the earths surface more greenhouse gases in the atmosphere will result in a increase in global temperature.

There are approximately five main climate types on Earth. Climate is the average weather conditions in a place over a long period of time30 years or more. High thin clouds trap some of the Suns heat.

When life first evolved more than 35 billion years ago Earths surface environment looked very different. Most of this change is warming because of human activities that release greenhouse gases into the atmosphere. This cools Earths surface.

There is no question that increased levels of greenhouse gases must cause Earth to warm in response. This is science not social studies I couldnt find science on there. This is part of the climate systems natural cooling mechanism and all climate scientists agree with this basic fact.

Based on a combination of paleoclimate data and models scientists estimate that when ice ages have ended in the past it has taken about 5000 years for the planet to warm between 4 and 7 degrees Celsius. Sea ice and snow retreat reducing the amount of sunlight the Earth reflects. Which of the following could be a reason the earths climate is getting warmer.

Lower-altitude clouds tend to help an area cool off. Climate Change in Earth History Climate has changed throughout Earth history. But recent research suggests that the Earths natural climate variabilitynatural short-term fluctuations in the climate system that occur on a year-to-year basis or longermay have played the most pivotal role of all by transferring excess heat from the Earths surface into the deep ocean.

Just as you feel more infrared heat radiation coming from a hot stove than from a warm stove the Earth gives off more infrared energy to space the warmer it gets. The earth is moving closer to the sun. Unless it is offset by some equally large cooling influence more atmospheric carbon dioxide will lead to warmer surface temperatures.

All three of these gases when theyre present in any planets atmosphere act the same way a blanket does when you place it over a warm. Some have suggested that current global warming is the result of natural variations in the Earths climate. The ocean warms and releases dissolved carbon dioxide which traps even more heat.

Clouds high up in the atmosphere have the opposite effect. The basic physics behind this has been establish for over 100 years. For example when forests are cut down less carbon dioxide can be taken out of the atmosphere.

Its generally drier in the winter when our local atmosphere is colder and its more humid in the summer when its warmer As carbon dioxide and other greenhouse gases heat up the planet more water evaporates into the atmosphere which in. Ice cores drawn from Greenland Antarctica and tropical mountain glaciers show that Earths climate responds to changes in greenhouse gas levels. Greenhouses gases such as carbon dioxide trap heat in the atmosphere that was on its way out to space causing Earths greenhouse effect to grow more intense warming the climate.

The impacts of climate change are growing and we need to stop adding to the problem. The warming of the past century07 degrees Celsiusis roughly eight times faster than the ice-age-recovery warming on average. Earths unexpectedly warm early climate is probably explained by some combination of less land erosion clearer skies a shorter day and a peculiar atmospheric composition before Earth had an oxygen-rich atmosphere.

The Short Answer. The stratosphere gets warmer during solar maxima because the ozone layer absorbs ultraviolet light. In recent years Earths climate has begun to change again.

Yale researchers have provided a new explanation for why Earths early climate was more stable and warmer than it is today. Unfortunately humans are very much the cause of climate change. And as you probably already know there are lots of different types of climates on Earth.

The sun was much weaker but Earth remained warm enough to keep liquid water at the surface. Warming is also linked to the destruction of tropical forests. Global warming is often linked to the burning of fossil fuels coal oil and natural gas by industries and cars.

Changes in the way land is used also have an impact on climate. Ozone depletion explains the biggest part of the cooling of the stratosphere over recent decades but it cant account for all of it. This warms Earths surface.

The explanation for the cyclical alternation of ice and warm periods stems from serbian mathematician milutin milankovitch 1879-1958 who calculated the changes in earths orbit and the resulting. But climate change isnt just a matter of the air temperature being a few degrees warmer. Wispy clouds high up in the atmosphere generally make an area warmer.

One possible explanation for the increase in average global temperature is global warming. More ultraviolet light during solar maxima means warmer temperatures. Driving cars gives off gases that trap heat in the atmosphere.

One of the most well-known natural climate oscillationsthe El Niño-Southern. The result of this buildup of greenhouse gases is that were trapping heat within the climate system. The temperature is rising at a similar rate to the increase in greenhouse gases in the atmosphere which made scientists hypothesize that the increase in greenhouse gases caused the temperature to increase.

Warming increases atmospheric water vapor which is a powerful greenhouse gas. What we dont agree on is how the climate system responds to warming by either. They tend to warm Earth more than they cool.

Large glaciers are melting in Antarctica. For the same reasonthe Earths surface is warmer in the southern hemisphere when it. Permafrost thaws and decomposes releasing more methane and carbon dioxide.
