Register

U.S. emissions of greenhouse gas from fossil fuels such as coal, oil, and natural gas fell a record 7 % in 2009 due to the recession and more efficient use of fuels 

In China and India the emissions increased by 9 and 6 %

Oceans  

 

Carbon Dioxide Emissions Causing Ocean Acidification to Progress at Unprecedented Rate.

 

 

Average pH of ocean surface waters has decreased from about 8.2 to 8.1. Models project an additional 0.2 to 0.3 drop by the end of the century. 

 

 

 NEW REFRIGERANTS  

 

First hydrocarbon refrigerant approved by the U.S.EPA for sale in U.S.

  • a patented blend of ethane, propane, butane, and other pure hydrocarbons
  • ASHRAE expected to give designation of R-441A
  • operates in equipment containing mineral oil
  • expected use in small charge refrigerators

GM announced it will switch to a new refrigerant for all 2013 models

  • HFO-1234yf
  • R-134a replacement
  • low GWP of 4

 

 International Energy Outlook

Global energy consumption grows by 49% from 2007 to 2035.

 

Liquid fuels remain the largest source of energy

 

World production of unconventional liquid fuels increases to 12.9 million barrels per day and accounts for 12%of total world liquids supply in 2035.

 

Use of natural gas for electricity generation increases from 33% in 2007 to 36% in 2035.

 

By 2035 world net electricity generation increases by 87%.

 

Nuclear power generation will grow 2% per year.

 

Hydropower and wind power will be the primary renewable energy sources.

 Global Warming 

NOAA: 2010 Tied with 1998 as Warmest Global Temperature on Record

 

The first eight months of 2010 tied the same period in 1998 for the warmest combined land and ocean surface temperature on record worldwide.
 

WMO/UNEP "Scientific Assessment of Ozone Depletion 2010"

Chlorine from ODSs and methyl chloride had declined to 3.4 ppb from its peak of 3.7 ppb

 

Increasing abundances of radiatively important gases, especially carbon dioxide (CO2) and methane (CH4), are expected to significantly affect future stratospheric ozone through effects on temperature, winds, and chemistry.

 

Abundances of HCFC-22, the most abundant HCFC, increased more than 50% faster in 2007-2008 than in 2003-2004
