Google Earth now shows CLIMATE CHANGE




The data is from the University of East Anglia Climate Research Unit
Users can see temperature changes at 6,000 global weather stations
There are 20,000 graphs showing monthly, seasonal and annual changes  dating back to 1850
The move is part of an effort to make climate change data ‘transparent’











The UN says climate change is " almost certainly " caused by humans, and now users of Google Earth you can see the impact it is supposed to have made changes in temperature in your local area .
Climate researchers from the University of East Anglia temperature records have been added to the world as a layer in the map service .
It allows users to zoom in on 6,000 weather stations worldwide and are monthly changes in seasonal and annual temperature 1850.


Users can access more than 20,000 graphics , in addition to the raw data from the Climate Research Unit Temperature Version 4 ( CRUTEM4 ) land surface temperature dataset air.
The set is one of the most used records of the climate system , and is based on readings from weather stations around the world.

The move is part of an ongoing effort to make the data on past climate , and climate change as accessible and transparent as possible .
Dr Tim Osborn of the Climatic Research Unit , University of East Anglia , said: " The beauty of using Google Earth is that you can instantly see where the weather stations are zoom in certain countries and see the sets station data much more clearly .
' The data itself comes from CRUTEM4 the latest figures , which have been available for free on our website and through the Met Office . But we wanted to make this set of key data as interactive and easy to use temperature as possible. "
As part of the layer of Google Earth climate , the world has been divided into 5 ° latitude and longitude of the network boxes .
The boxes are about 550 km wide along the line of Ecuador , tapering towards the north and south poles.

The red and green checkerboard covers most of the Earth and indicates the areas of land where the station data is available .

Clicking on a cell in the mesh annual temperatures reveals that area , as well as links to more detailed data from the station.
While the new initiative does not allow greater accessibility, the research team , admitted he did not expect to find errors.
' This dataset combines monthly records of 6,000 meteorological stations around the world - some of which date back over 150 years, " said Dr. Osborn.
- That's a lot of data , so we would expect to see some bugs.
' We really encourage people to alert us to any records that appear unusual .
He added that there are some gaps in the network , in remote locations where there is no weather , such as the Sahara desert in Africa stations .
Moreover, the location of some weather stations is not exact because the issues of fact latitude and longitude for each parcel is limited to a decimal .
This means that some markers stations could be a few miles from the actual location.
' This is not a problem because scientifically temperature records do not depend on the precise location of each station. But it is something that will improve over time as more detailed location information is available , "continued Dr. Osborn.
