Global 'sunscreen' has likely thinned, report NASA scientists
A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases – sunlight blocked by dust, pollution and other aerosol particles – appears to have lost ground.
The thinning of Earth’s "sunscreen" of aerosols since the early 1990s could have given an extra push to the rise in global surface temperatures. The finding, published today in the journal Science, may lead to an improved understanding of recent climate change. In a related study published last week, scientists found that the opposing forces of global warming and the cooling from aerosol-induced "global dimming" can occur at the same time.
Winter in the Northern Hemisphere this year has been the warmest since records began more than 125 years ago, a US government agency says.
The combined land and ocean surface temperature from December to February was 0.72C (1.3F) above average
The Japanese capital has experienced its first winter without snow for 131 years, weather officials say.
The Japan Meteorological Agency said it had recorded no snow in central Tokyo between December and the end of February, the official winter months.
This the first time no snow has fallen in winter since records began in 1876, the agency said.

Particles in the atmosphere from pollution and natural volcanic eruptions which caused a phenomena called Global dimming ........ has diminshed in a new report from NASA.

This has been a concern for me for a while now, ever since I learned about global dimming.
I believe this report may also accounts for the following news:
Winter warmth breaks all records

Snowless winter first for Tokyo

Now this is truly what we call runaway effect.
We need to somehow increase the particulate in the atmosphere in a non toxic way as well as reduce carbon emissions to be able to fight global warming.
I wonder if all the stories of chem trails are really a secret project to increase particulate??
All the best,

So, how does a snowless winter have anything to do with Global Warming and a temperature increase of less than 1.5 degrees? 1.5 degrees is not enough to stop snow from falling, sorry.

But it did not see the high temperature as evidence of man-made global warming.

From the same article:
But it did not see the high temperature as evidence of man-made global warming.
However, Mr Lawrimore said the research was part of the Intergovernmental Panel on Climate Change (IPCC) process, which released a report last month that found global climate change "very likely" has a human cause.
"We know as a part of that, the conclusions have been reached and the warming trend is due in part to rises in greenhouse gas emissions," he said.
The IPCC panel concluded that it was at least 90% certain that human emissions of greenhouse gases rather than natural variations are warming the planet's surface.
The combined temperature for the December-February period was 1.3 degrees F (0.72 degree C) above the 20th century mean, the agency said.
Lawrimore did not give an absolute temperature for the three-month period, and said the deviation from the mean was what was important. He did not provide the 20th century mean temperature.
