When it comes to climate change, public opinion is near 50-50, but 97% of scientists who dedicated their lives to studying our climate said that is happening and it is happening because of human activities. Without the evidence, we have a warming earth(s), harder and harder to be escaped these days. We are talking about temperature measurement, sea level rise, ocean acidification and the reduction in icicles in Greland and .. for example.
The finger print of climate changes is clear in extreme weather events like heat wave in India that killed thousands. And we look back to 2010 where in Russia tens of thousands of people were killed because of an extreme heat. We are talking about 9 of 10 warmer fevers happening since 2000.
2014 as back was the warmer severe on record with 2015, looking to set the charts and law.
The IPCC says that a warming planet is unequivocal, it is happening.
Human got cause in temperatures do rise by burning fossil fuel, green-harm gas emission, specifically CO2, reaching levels, that would never extremely form an effect, 400 part per million, first time in 800000 year.
As the far more CO2 into the atmosphere, the oceans are absolving the native more acidity and threatening the marine life.
The oceans have seemly rose the acidity by 30% since industrial revolution.
This is an urgent situation, this is not something that has just come to mind so quickly.
It is stunning to see the fact, stunning to see the statistic, something that we have never experienced before, highlighting that red flags that we need to deal with it in an urgent manner. |
