NASA Climate Scientist Explains 15-Year ?Global Warming Hiatus? « CBS DC
Lol, so while his pause was occurring, the government stats still had record breaking temperatures set every month for like 8 years, lolol
I guess they shouldn't 'adjust' those temperatures so hard.

Global Warming Pause Puts 'Crisis' In Perspective - Forbes
A NASA scientist described a recent global warming hiatus that shows Earths surface temperatures warming at a slower rate than previous decades but it is still warming.
Norman Loeb delivered a lecture entitled, The Recent Pause in Global Warming: A Temporary Blip or Something More Permanent? at the NASA Langley Research Center auditorium on Tuesday. The talk addressed challenges to scientists and increased skepticism among climate change skeptics due to the recent hiatus of global warming.
The federal space agency climate scientist explored research into a slow-down in surface warming over the last 15 years referred to as the Global Warming Hiatus. In recent years, the global mean surface temperature on Earth has increased at a rate that is about one-third of that from the past 60 years.
The global warming hiatus occurred despite record-breaking temperatures in the 2000s, retreating Arctic sea ice, rising sea levels and a record high global concentration of carbon dioxide in the atmosphere, according to a statement released by NASA.

Global Warming Pause Puts 'Crisis' In Perspective - Forbes
The IPCC-affiliated scientists have made guesses that the unknown climate components will dramatically accelerate the modest warming caused directly by human carbon dioxide emissions. So-called climate skeptics have argued the UN guesses consistently overestimate the warming propensity of the unknown climate components.
The real-world temperature data appear to support the skeptics. Even before the recent global warming pause, temperatures were warming at a relatively modest pace. The ongoing global warming pause is rendering the longer-term pace of warming still more modest.
IPCC computer models dating from 1990 through the present have consistently predicted at least 2.4 degrees of global warming per century. Such warming would require at least 0.24 degrees Celsius per decade, for which we should see at least 0.80 degrees Celsius warming since 1979. However, real-world warming since 1979 is occurring at less than half that pace. And there has been absolutely no real-world warming during the past 17 years.
IPCC adherents claim short-term variance is masking longer-term climate trends. According to this line of reasoning, the 35 years since 1979 are simply not long enough to form meaningful conclusions about the longer-term pace of global warming.
This line of argument is unpersuasive for two important reasons:
First, the admittedly less reliable ground-based mercury temperature readings from the mid-1940s through the late 1970s reported global cooling during the three decades immediately prior to the satellite era. Accordingly, the time period for which real-world temperatures are not rising nearly as rapidly as IPCC predictions is now not just 35 years, but approximately 70 years.
Second, and even ignoring the 1940s-1970s global cooling, for global temperatures to meet IPCCs predicted 2.4 degree rise by late this century, global temperatures must immediately and that means immediately begin rising at a sustained 0.30 degrees Celsius per decade. That has never come close to occurring during our modern warm period, and the ongoing global warming pause suggests that is unlikely to begin happening any time in the foreseeable future, either.
