The hockey stick gang assumed annual growth rings were due to temperature when most are
about precipitation levels.
Not exact matches
Uncertainty
about rain, little uncertainty
about sea
level rise Climate change could also affect
precipitation in California, though the two models USGS used in its research produced different results.
Sea surface temperatures are higher because of climate change, he said, adding
about 5 to 10 percent to
precipitation levels.
Although Everest is
about 1,500 miles to the north and not at sea
level, these storms can greatly impact the mountain, bringing heavy
precipitation.
For instance, Milly et al., 2003 (Open access) used computer simulations and results from the CMAP reanalysis of
precipitation levels to calculate that climate - related changes in water storage on land were causing a sea -
level rise of
about 0.12 mm / year in the period 1981 - 1998 (although, they admitted they couldn't calculate an error bar for that estimate).
Finally, while economics may be critical to your definition of «catastrophic» anthropogenic global warming, economics says nothing
about the science underlying the projections of sea
level rise, the physics of Arctic amplification, changes to albedo that lead to greater warming that may lead to significant releases of methane clathrate deposits, regional projections of reduce (or enhanced)
precipitation, and so on.
I've presented videos and gif animations to show the impacts of ENSO on ISCCP Total Cloud Amount data (with cautions
about that dataset), CAMS - OPI
precipitation data, NOAA's Trade Wind Index (5S - 5N, 135W - 180) anomaly data, RSS MSU TLT anomaly data, CLS (AVISO) Sea
Level anomaly data, NCEP / DOE Reanalysis - 2 Surface Downward Shortwave Radiation Flux (dswrfsfc) anomaly data, Reynolds OI.v2 SST anomaly data and the NODC's ocean heat content data.
Your political views have nothing whatsoever to do with the physical facts of increasing CO2 due to our emissions, the warming that will cause (~ 1.1 C / doubling), the feedbacks that will occur (to a total of
about 3C / doubling), crop movements, sea
level rise, ocean acidification,
precipitation changes, etc..
Projected temperature would increase by 2050 by
about 2 °C above the current
level (a warming similar to that predicted by the ensemble mean of the CMIP5 simulations) and
precipitation would decrease by an additional 30 % compared to the current conditions.
If we agree with you that CO2 readings are false and surface temperature rise is false, then what
about sea
level rise,
precipitation reduction, reduction in the temperature of the upper atmosphere, or evaporation pan reduction?
We can also think
about hydrological drought, or how decreased
precipitation affects streamflow, soil moisture, reservoir and lake
levels, and groundwater recharge.
The climate science question is easily separated from policy because it only talks
about temperature,
precipitation, sea
level, sea ice, etc., regardless of humans.
