Describe What a Warmer Earth Might Be Like

Global warming will shift major climate patterns possibly prolonging and intensifying the current drought in the US. Or of the earth without the atmosphere and if the Earths surface was like the moons.

What Is Global Warming Live Science

Cools the lower atmosphere and warms the upper.

. This could be the biggest example yet of climate change shaping human history. If you took a model globe and wrapped it up. The coldest it would get at night would be 3C 37F.

The last time the Earth was as warm as it is now was over 11000 years ago. Both summer and winter temperatures can be extreme because the influence of polar air masses is strong in winter while warm tropical air dominates in summer Warm moist air causes summers to be generally wetter than winters especially in latitudes that are close to the tropics. If we find ways to spew far fewer heat trapping gasses into the air global average temperature will increase less than 1 Celsius this century which will keep Earth a livable place.

For fun I set up a relatively simple model to simulate what the climate on an earth with a 0 degree tilt might be like. There are a few details that make this more of a. Global average temperature will increase between 3 and 5 Celsius 54 to 9 F.

The good news is that this doesnt have to happen. Oceans covers 70 of our planet and it takes a lot of energy to heat up that much water not to mention the air and land. Ice caps lakes and rivers which now flow to vast expanses of soil and underground water are still available.

This is what the Earth could look like within 100 years if we do barring huge leaps in renewable energy or carbon-capture technology. Thats not enough to get a decent worldwide water cycle going even if we melted the ice caps. The diameter of Earth is 12742km and the atmosphere is about 100km thick.

Rising sea levels more extreme weather events and acidification of the oceans. Higher albedo the Moon is quite dark and there could be a bright coating of salt where the oceans used to be - but might radiate less at night and a little bit more heat. During the day clouds can make the temperature on Earth cooler by blocking heat from the Sun.

The white ring of bleached rock on the once-red cliffs that hold Lake Powell indicate the drop in water level over the past decadethe result of repeated winters with low snowfall. At night clouds can make Earths temperature warmer by trapping heat that came from the Sun. Life on an Earth with no seasons would be an endless struggle.

A point in favor of possible life. The temperatures at the poles would never raise above 46C 115F during the day. In 10000 years if we totally let it rip the planet could ultimately be an astonishing 7.

Based on what weve observed in our own solar system large gaseous worlds like Jupiter seem far less likely to offer habitable conditions. Earth were unwaveringly warm and dry. Climate Explained is a collaboration between The Conversation Stuff and the New Zealand Science Media Centre to answer your questions about climate change.

As the Earth continues to warm this is increasingly melting ice from Greenland and Antartica which is feeding more freshwater into the oceans. Other similarities to Earth come into sharper focus in the search for life. Interestingly enough if the Earth was 60 million km 40 million miles further away from the Sun a 90-degree axial tilt wouldnt be so bad.

And so these regions can serve as archetypes for what a seasonless Earth might be like. If you have a question youd like an. The greenhouse effect which acts to warm the lower atmosphere and cool the upper atmosphere and atmospheric convection thermals clouds precipitation which does just the opposite.

Find out what it might be like to live on other worlds in our solar system from Mercury to Pluto and beyond in our 12-part series. Warming is also causing the oceans to rise from thermal expansion. Earths atmosphere is a remarkably thin layer of gases that sustain life.

Its sort of like clouds are wrapping Earth in a big warm blanket. Many rocky planets have been detected in Earths size-range. 31 2009 to mention latent heat release The climate of the Earth is profoundly affected by two competing processes.

Three big ones are. No water no snow no forests etc that is what the surface would come to. Added together those sources total about 35 percent of our present water supply the other 965 percent having disappeared with the oceans.
