Global Warming Proved Not a Hoax

The 130 years shows the effect of human fossil fuel burning.
Humans didn't burn much fossil fuel further back in time.


130 Years of Earth Surface Temperatures
http://apod.nasa.gov/apod/ap130731.html

Explanation: How has the surface temperature of Earth been
changing? To help find out, Earth scientists collected temperature
records from over 1000 weather stations around the globe since
1880, and combined them with modern satellite data. The above
movie dramatizes the result showing 130 years of planet-wide
temperature changes relative to the local average temperatures in
the mid-1900s. In the above global maps, red means warmer and blue
means colder. On average, the display demonstrates that the
temperature on Earth has increased by nearly one degree Celsius
over the past 130 years, and many of the warmest years on record
have occurred only recently. Global climate change is of more than
passing interest -- it is linked to global weather severity and
coastal sea water levels.



Draft APS Statement on Climate Change
http://judithcurry.com/2015/04/07/dr...limate-change/

On Climate Change:
Earth’s changing climate is a critical issue that poses the risk of
significant disruption around the globe. While natural sources of
climate variability are significant, multiple lines of evidence
indicate that human influences have had an increasingly dominant
effect on the climate warming observed since the mid-twentieth
century. Although the magnitudes of future effects are uncertain,
human influences on the climate are growing. The potential
consequences of climate change are great and the policies of the next
few decades will determine human influences on the climate for
centuries.



Berkeley Earth Report 2014
http://static.berkeleyearth.org/memo...Newsletter.pdf

Berkeley Earth has constructed an estimate of the global
average temperature during 2014, including land and sea.

The "margin of uncertainty" represents the 95% confidence
limit, obtained principally by comparison of results from
subdividing the data into independent sets. The global
temperature estimate is compiled as combination of a
land-only temperature estimate constructed by Berkeley Earth
directly, and an ocean temperature estimate produced by the
Hadley Centre in the UK and modified by Berkeley Earth.
