The earth is now warmer than at almost any time since the end of the last ice



The earth is now warmer than at almost any time since the end of the last ice age and, on parcent trends, will continue to reach a record high temperature for the entire period since the down of civilization , a stady has found .

The stady publiched in the journal Science aims to give a Global overview of Earth’s temperatures over the 11300 years relatively balmy period known as  the Holocene that began after the last major ice age ended and encompasses all of recorded human civilization.
Their data(compiled by studying such as ice cores, fossils and ocean sediment) back over a much longer era than previous research , which went back 1,500 years.
Scientists say it is further evident that mordern day global warming isn’t  natural , but the result of rising carbon dioxide  emissions that have repidly grown since the industrial revolution began roughly 250 years ago.scientist say that if natural factors were still governing the climate, the Northern Hemisphere would probably be destined freeze over again in several thousant years .Instead, scientists believe the enormous increase in greenhouse gases caused by industrialization will almost certainly prevent that.
Shaun Marcott, a geologist at oregan state University,says “global temperatures are warmer than  above 5% of anything we’ve seen over the last 11,000 year or so”The other way to look at that is 25% of the time since the last ice age, it’s been warmer than now.

It’s taken just 100 years for the average temperature to change by 1.3 degrees, when it took 5000 years to do that before.By the end of the century, climate-warming ,models predict an additional increase of  2 to 11.5 degrees. Due largely to carbon emissions, the study, noted.
