What is the number of years of data needed to predict Global warming?
Scientists have been using the data over the last 250 years (since the start of the Industrial Revolution) to monitor the rise of Global Warming.
What is the reason scientists think the tundra has shrunk by almost 20 over the last 20 years?
Global warming is melting the tundra.
Is global warming a rapid or slow change?
Global warming is a rapid change. The earth's temperature has risen very fast in the past 50 years, compared to the very gradual rise over the past 12,000 years, the time of the last Ice Age.
Has there been global warming for the past 11 years?
Yes, the ten hottest years on record have all occurred since 1998.
An increase in average temperatures around the planet is known as what?
Global Warming
How has the Earth's natural warming system been thrown out of balance over the last 200 years?
earths natural warming system been thrown out of balance over the last 200 years
Why is global warming cold?
Global warming is not cold, as it (if it really exists) causes to temps around the world to increase. There was no doubt that the earth went through a period of warming, but now this seems to have reversed itself over the last 17 years. Many areas are experiencing some of the coldest winter temps in decades this year.
Is global warming anthropogenic?
Yes, global warming is anthropogenic, which means 'caused by human activity'. Humans began burning fossil fuels (coal, oil and natural gas) at the start of the Industrial Revolution, 200 years ago. Over the years this has added billions of tonnes of carbon dioxide to the atmosphere, and is the main cause of global warming.
Did global warming bother humans just after the ice age?
After the ice age, humans likely did not directly recognize or attribute global warming as a concern. Instead, they would have been more focused on adapting to the changing environment and finding ways to survive in the new climatic conditions. The concept of global warming as a result of human activities is a more recent understanding.
What trends have been observed in global temperature over the past 2,000 years?
Over the past 2,000 years, global temperature trends have shown fluctuations, with periods of warming and cooling. However, in recent decades, there has been a notable increase in global temperatures, largely attributed to human activities such as burning fossil fuels and deforestation. This phenomenon is known as global warming.
What will be the condition of earth in next 50 years?
There is way too much emphasis on "Man made global warming." There is no such thing. There is global warming and global cooling that has taken place over the past ten thousand years. It is cyclical. Most of the global warming that has taken place was prior to any use of fossil fuel. Don't let people try to pull the wool over your eyes. Don't let them scare you into their mold. That's what they are trying to do. The earth will be in fine shape in 50 years.
Why is the process of global warming crucial to earth?
The process of global warming, that is the recent warming over the past 200 years since we began to seriously burn fossil fuels (coal, oil and natural gas), is notcrucial to earth. In fact it is extremely dangerous.The greenhouse effect, which has kept the earth warm enough for life for millions of years is crucial to earth. But the greenhouse effect is not the same as global warming.
