The last ice age, known as the Last Glacial Maximum, occurred due to a combination of factors such as changes in the Earth's orbit and tilt, which affected solar radiation distribution, as well as the release of volcanic aerosols and greenhouse gases. These factors led to the cooling of the climate and the expansion of ice sheets across much of the Northern Hemisphere.

The increase in carbon dioxide in your atmosphere over the last 150 years was caused primarily by?
The increase in carbon dioxide in the atmosphere over the last 150 years can primarily be attributed to human activities, particularly the burning of fossil fuels such as coal, oil, and gas for energy. Deforestation and land use changes have also contributed to this increase by reducing the planet's ability to absorb carbon dioxide from the atmosphere.
How has the percentage of carbon dioxide changed in the last 4500 million years?
The percentage of carbon dioxide in the atmosphere has varied significantly over the last 4500 million years. There have been periods with much higher CO2 levels, such as during the early Earth with levels over 100 times higher than today, and periods with much lower levels, like during the last ice age around 20,000 years ago. However, the rapid increase in CO2 levels over the past century due to human activities is unprecedented in Earth's history.
Has atmospheres carbon dioxide changed over last 150 years?
Yes, atmospheric carbon dioxide concentrations have increased significantly over the past 150 years due to human activities such as burning fossil fuels and deforestation. This increase in carbon dioxide is a major driver of climate change and is contributing to global warming.
Why has acid rain increased over the last 20 years?
Acid rain has increased over the last 20 years due to factors such as industrial activities, vehicle emissions, and deforestation releasing pollutants like sulfur dioxide and nitrogen oxides into the atmosphere. These pollutants combine with water vapor to form sulfuric acid and nitric acid, leading to acid rain.
What is the change in the amount of carbon dioxide in the air over the last 50 years?
Atmospheric CO2 has gone from something on the order of 310 ppm (parts per million) to over 380 ppm in the last 50 years. That's about a 20% increase. In just 50 years. A graph from Wikipedia is linked. Go look. Can anything be more plain than that we, the people, are making more CO2 and making it more quickly than it was made before?

How long does a space shuttle last?
it was originally designed to last 10 years, but was retrofitted to be lighter and this caused it to last until present day, where project constellation will take over.
What are the damages caused by a tornado in US for the last five years?

How much has the Kwakiutl population declined over the centiries?
It has declined about 50,000
What caused the increase in carbon dioxide in your atmosphere over the last 150 years?
The primary reason for the increase in carbon dioxide levels in the Earth's atmosphere over the last 150 years is the burning of fossil fuels such as coal, oil, and natural gas. This releases carbon dioxide that had been locked away for millions of years into the atmosphere, leading to a rise in atmospheric CO2 levels and contributing to climate change.
