It Now Appears We Will Pass the Critical Global Warming Target of No More that 2 Degrees Celsius About 2039 or Sooner. What it Means to Your and Your Children's Future.

Our review of the most current climate research points towards passing the world's most commonly recognized critical global warming target of no more that 2 Degrees Celsius warming (over pre industrial levels,) in  2039 or sooner.

That is very very bad news for future generations. Here is what missing the 2 degree Celsius target (or even less than the two degree target means to your future,):

The IPCC climate commission of the United Nations found that only moderate warming would lead to more extreme weather events and wipe out coral reefs and lead to the loss of Arctic sea ice in summer.

For example, warming of more than 1.5 degrees above pre-industrial levels (or less than twice the warming that has already occurred) would lead to the loss of 90% or more of all coral reefs.
 

Extreme weather events posed a “high risk” with an additional 1 degree warming above recent levels, or 1.6 degrees above pre-industrial levels.
 

“Extensive” species extinctions would follow additional warming of 3 degrees Celsius above recent levels, or 3.6 degrees above pre-industrial levels.
 

With more than 3 degrees warming above recent levels (3.6 degrees above pre-industrial), the potential for large and irreversible sea level rise took hold.
Beyond that, farmers worldwide would see serious crop damage.
 

“Global temperature increases of about 4°C or more above late-20th-century levels, combined with increasing food demand, would pose large risks to food security globally and regionally.”
 

In the longer term, impacts were more serious even at lower levels of warming. For example, over the next 1,000 years or so, the whole Greenland ice sheet would melt at warming of 1 to 4 degrees above recent levels (1.6 to 4.6 degrees above pre-industrial), contributing up to 7 meters sea level rise, the IPCC said.
 

Regional Risks:
 

The IPCC’s summary report described climate risks by region, at 2 and 4 degrees warming above pre-industrial levels.
 

In Africa, the biggest risk was to crop production, risks described as “very high” with or without adaptation with 4 degrees warming, and “medium” for 2 degrees with adaptation.
 

In Europe, the biggest threats were in the Mediterranean, from reduced water availability and economic losses from heat waves including wild fires.
 

In Asia, the biggest losses were also from heat waves, which adaptation could only ease slightly at 4 degrees warming.

In Australia the biggest risk was to coral reefs, which could not be protected at 4 degrees warming and faced high risks even with 2 degrees.
 

In North America the biggest threat was to natural ecosystems including forests from wild fires and water stress, where adaptations may not be able to cope with 4 degrees warming, and risks were also high with 2 degrees warming.
 

In South America, the biggest risk was to water availability, and in Polar Regions from melting ice and permafrost, which also impacted freshwater.
