Global Warming Report


GlobaGlobal Warming Reportl Warming Report
Friends, global warming is now "unequivocal," and scientists are more than 90 percent sure that humans are mainly to blame for Earth’s recent heat increase. Or, so says the latest report from the Intergovernmental Panel on Climate Change (IPCC), the main international network of climate scientists.

The report, released Friday, is actually the first part of a more comprehensive assessment set to be published in stages this year (the IPCC conducts such assessments every five or six years). But it’s hard to imagine that the other parts will pack as much punch as this one.

The head of the United Nations Environment Program even said, "February 2 will be remembered as the date when uncertainty was removed as to whether humans had anything to do with climate change on this planet." Some will surely dispute that, but the IPCC’s findings are clearly worth a look.

So, we’ve pulled the report’s highlights into three key categories for you: things IPCC scientists say unequivocally, things they say are "very likely" (have a more than 90 percent chance of being so), and things they say are "likely" (have a more than 66 percent chance of being so).

What IPCC Scientists Say Unequivocally

It’s Getting Warmer

"Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level."

"Eleven of the last twelve years (1995-2006) rank among the 12 warmest years in the instrumental record of global surface temperature (since 1850)."

"The linear warming trend over the last 50 years . . . is nearly twice that for the last 100 years."

Sea Levels Are Rising

"Global average sea level rose at an average rate of 1.8 mm per year over 1961 to 2003. The rate was faster over 1993 to 2003, about 3.1 mm per year."

"Observations since 1961 show that average temperature of the global ocean has increased to depths of at least 3000 m and that the ocean has been absorbing more than 80 percent of the heat added to the climate system. Such warming causes seawater to expand, contributing to sea level rise."

"Mountain glaciers and snow cover have declined on average in both hemispheres. Widespread decreases in glaciers and ice caps have contributed to sea level rise."

What IPCC Scientists Say Is "Very Likely"

We’re to Blame

"Average Northern Hemisphere temperatures during the second half of the 20th century were . . . higher than during any other 50-year period in the last 500 years."

"Global climate change of the past fifty years . . . is not due to known natural causes alone."

"Most of the observed increase in globally averaged temperatures since the mid-20th century is . . . due to the observed increase in anthropogenic greenhouse gas concentrations."

It Will Get Worse

"Continued greenhouse gas emissions at or above current rates would cause further warming and induce many changes in the global climate system . . . larger than those observed during the 20th century."

"Hot extremes, heat waves, and heavy precipitation events will continue to become more frequent."

What IPCC Scientists Say Is "Likely"

We’re Changing the Weather

"There has been significant anthropogenic warming over the past 50 years averaged over each continent except Antarctica."

"Anthropogenic forcing . . . [has] contributed to changes in wind patterns, affecting extra-tropical storm tracks and temperature patterns in both hemispheres."

"Future tropical cyclones (typhoons and hurricanes) will become more intense, with larger peak wind speeds and more heavy precipitation."

  1. Good  Morning, dear one!
    It\’s a shame, really, that in our quest for "better and more", the world, our true natural resource is dying away.  Would we still do the same?  Probably.  We are human beings are so sure we have all the answers. 
    Love the verse you sent me.  I must stretch and growl, a whole lot more!
    Smooches, hon!

  2. I read your response to Thotman\’s blog on Global Warming which is what lead me to check out your space several days ago.  While I completely agree with the scientific evidence of Global Warning and there is an incredible need for us to do something about it, I\’m going to stick with my initial view on the matter.  When we aren\’t willing (and when I say we, I mean Americans) to make any sacrifices to solve the problems that are effecting all of us every day whether we realize it or not i.e., the hungry and homeless, a broken health care system, the working poor, etc. etc., I really don\’t feel much hope that people will do so for something they don\’t even believe will effect them.  After all, Jesus is going to return to scoop up \’the righteous\’ before it gets too bad and it will only be us non-believers left here to suffer, right?
    I will be doing my little part and maybe that\’s the best we can hope for … we certainly can\’t wait for our government to find solutions or even admit there\’s a problem.
