How much does CO2 needs to be reduced today to get the climate back to normal?
What is considered a "safe" level?
How much CO2 is in the atmosphere now?
If we took action now, we wouldn't see it back to normal for twenty five years. If we do nothing, we can expect it to start compounding. An ice age can stop this, it has done it before. The correction of the earth to this is to form an ice age.
Where can I look at those estimations?
Ihere in Southern Ca it is way warmer than usual. The whole southwest is having one very mild winter.
Imho, the GEo-engineering is causing the drought to be worse. from Texas all the way to Cali, massive drought. worst ever.
OVERALL.. the funny thing is the 'warmers' stated very clearly that global warming would include harsher winters. then when it is harsh, people ridicule warming. that is so typical..

Warmer summer and winter
North-west will experience more warming in the winter and will likely increase by at least 5°C in about 30-50 years.
Central and east Canada will experience more warming in the winter, while central and east coast US will warm more in the summer months.
I am so past trying to understand the reasons behind climate change. It has gone beyond that point now because, in my opinion, we are where we need to begin dealing with the effects. While the crazy weather we have been experiencing lately in places as divergent as Alaska and California, England and Australia or even Russia and Canada's arctic tundra regions, the overall issue is one of dangerous situations, whether it is heat waves, floods or hellish storms.
Los Angeles, a metropolis perched on the edge of a coast, can expect to experience sea level rise of as much as two feet due by 2050 due to climate change, according to current projections.
In anticipation, a team from USC partnered with the City of Los Angeles to gauge the impact of the rising tides on local communities and infrastructure. The results, according to a report that was released today, are a mixed bag -- but at-risk assets can be protected by proactive planning and early identification of adaptation measures, according to the report's authors.
"Some low-lying areas within the City's jurisdiction, such as Venice Beach and some areas of Wilmington and San Pedro, are already vulnerable to flooding," said Phyllis Grifman, lead author of the report and associate director of the USC Sea Grant Program. "Identifying where flooding is already observed during periods of storms and high tides, and analyzing other areas where flooding is projected are key elements in beginning effective planning for the future.”
Australia’s warmest September on record
Australia’s record for warmest 12-month period has been broken for a second consecutive month. This continues a remarkable sequence of warmer-than-average months for Australia since August 2012.
September 2013 was easily Australia’s warmest September on record. The national average temperature for September was +2.75 °C above the long-term (1961–1990) average, which also sets a record for Australia’s largest positive anomaly for any monthly mean temperature. The previous record of +2.66 °C was set in April 2005.
The mean temperature for Australia, averaged over the 12 months from October 2012 to September 2013, was 1.25 °C above the long-term average. This was also 0.17 °C warmer than any 12-month period prior to 2013.
