Mann-made Global Warming.

Steven Goddard, on his Real Science blog shows

History Of How The Hockey Stick Was Manufactured

IPCC Graph
There wasn’t any hockey stick prior to the year 2000.
The 1990 IPCC report showed that temperatures were much cooler than 800 years ago.

 Steve then details, with graphs, the original IPCC graph showing the MWP and the LIA (See image) followed by Briffa's tree proxies; 1975 NAS report; NCAR graph; USHCN daily temperature data; GISS graph; etc etc

Hansen getting rid of the 1910-1940 warm period gave Mann cover to claim that something was wrong with Briffa’s trees – and throw them out. This opened the door for the creation of hockey stick.
Once the flood gates opened, they went nuts – erasing the MWP and LIA, erasing the 1930s and jacking up recent temperatures. All over the world, the past got cooler and the present  got warmer.

Real Science concludes:
And now we have this completely manufactured temperature trend. The spike that we see is indeed Mann-made, and Hansen-made.

  1. Are the sea levels rising? Yes, according to the unbiased scientific data easily accessible to everyone via Google. Sea levels have been rising at a consistent rate of 2 - 3mm per year for the past 6000 years. At this rate the sea level will increase about one inch over the next ten years. Current research on the Pacific atolls indicates the atolls are growing at the same rate. Contrary to popular misinformation, atmospheric CO2 levels are not the highest they have ever been.

    Evidence suggests much of the ice that regularly melts from the polar caps during the summer becomes water vapour that is redistributed as snow further inland, which inturn freezes and recycles back into glaciers. Throughout our planetary history the ice ages have occurred for much longer periods of time than the brief intermittent cycles of warmth. Humankind and population growth has only flourished during the warm cycles. Our global population is now the highest its ever been and its still growing. Controlling population growth is within the realm of human potential but controlling the planetary weather isn't.

    During the next 100 years it's more likely over population will be the biggest concern for future generations to address than any of the theoretical threats from global warming, aka 'climate change'.
