Why is this climate change different?
This climate change is different:Because of its speed. Previous climate changes took many thousands of years, this has taken 200 years.Because it is being caused by human activity, deforestation and burning fossil fuels (coal, oil and natural gas).
How many degrees has the earth warmed in the past 150 years?
1.5 degrees.
What is the critical difference between today's global warming and Eath's previous climate changes?
Earth's previous climate changes were natural and took place over tens of thousands of years.Today's global warming is caused by human activity (the burning of fossil fuels and deforestation) and is happening very quickly (gradually since 200 years ago and then very rapidly since 1980).
How long does climate take to change?
The minimum time scale used by climate scientists is five years. This is why most of their data is represented by seasonal measurements (to indicate the extent of noise) and a five year running average to chart climate trends. Natural climate change during most of the Cenozoic has occurred over a hundred thousand year cycle known as the Milankovich Cycle. This has been earth's primary driver of climate for many millions of years.
Why is the climate changing so fast?
It normally takes thousands of years, for example, from the last Ice Age till now. However the recent global warming and climate change has been happening extremely fast, like in the past twenty or thirty years. The earth has never warmed up so fast before. This is why climate change is so dangerous!
What is known as climate?
The temperature around us is weather. The temperature trends over years and a large area is climate. For example the weather may be cold today. The climate though has warmed almost 0.2 degrees in the past 150 years in this area.
How did government spending during the Civil War compare to that during previous years?
During the Civil War government spending tripled compared to previous years. The United States government was forced to take a loan from France.
What conditions allowed so many different kinds of mammals to evolve during the Cenozoic era?
Earth's climate warned during the tertiary period which allowed marine life to evolve and grasses evolved as well which meant grass eating mammals had a food source. Then the earths climate cooled facing a series of ice ages. Then 20000 years ago earths climate warmed again so ocean animals and land animals thrived.
How did the presence and absence of ice affect the early settlement of Canada?
The first groups to arrive moved south because Canada was covered with ice. Over thousands of years, though, Earth’s climate warmed. The ice sheets over most of Canada melted. As Canada warmed, people occupied the land there.
How do the growth rings of a tree provide evidence of climate conditions of previous years?
A2. Using fossil tree rings, a complete year by year record is available for about 11 000 years, and with an accuracy of as little as 1 year! Dendrochronology is the name of this science.A1. Thicker rings indicate that the climate during that time period was favorable to growth, which may indicate that there were optimal rainfall and temperatures during that time, whereas thinner rings indicate the opposite.
Why is this climate change different?
This climate change is different:Because of its speed. Previous climate changes took many thousands of years, this has taken 200 years.Because it is being caused by human activity, deforestation and burning fossil fuels (coal, oil and natural gas).
What started climate change?
Climate change is a natural phenomenon. It has happened many times in earths past and will continue to do so.A:Climate change is the result of the global warming that has been happening, especially in the last forty years, when the earth has warmed more quickly than it has ever warmed before. Global warming is being caused by deforestation and the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2).
How many degrees has the earth warmed in the past 150 years?
1.5 degrees.
What makes the current extinction events different from the previous?
Because - previous extinction events happened due to natural causes. Over the last 200 years, the human race has wiped out more species through their selfish domination of the planet - than the last 20,000 years of 'natural' disasters !
Approximately How many real tress are sold during Christmas?
Enough to delay the effects of climate change by a few years.
