Don’t blame God or nature. We’re the culprits (By David Suzuki)

Don’t blame God or nature. We’re the culprits. 

By David Suzuki

Traditionally, we’ve labelled events over which we have no influence or control “acts of God” or “natural disasters.” But what’s “natural” about climate-induced disasters today?

Scientists call the interval since the Industrial Revolution the “Anthropocene,” a period when our species has become the major factor altering the biological, physical and chemical properties of the planet on a geological scale. Emp...

The Paris climate deal won’t save us – our future depends on de-growth

Posted by Maria Spiliotopoulou on Wednesday, September 27, 2017, In : Global 

By Jason Hickel. From The Guardian. Published on July 3rd, 2017. 


When Donald Trump pulled the United States out of the Paris climate deal, the world reacted with outrage. And rightly so: the agreement represents a remarkable achievement in international diplomacy – a breakthrough after 20 years of failed climate negotiations. But as we rally to defend the Paris deal against the onslaught of an ill-informed bully, we need to resist the temptation to cast the agreement as some kind of saviour...

Scientists made a detailed “roadmap” for meeting the Paris climate goals. It’s eye-opening

Posted by Maria Spiliotopoulou on Friday, April 7, 2017, In : Climate change 

Article by Brad Plumer 
  Mar 24, 2017  


Back in 2015, the world’s governments met in Paris and agreed to keep global warming below 2°C, to avoid the worst risks of a hotter planet. See here for background on why, but that’s the goal. For context, the planet’s warmed ~1°C since the 19th century.

One problem with framing the goal this way, though, is that it’s maddeningly abstract. What does staying below 2°C entail? Papers on this topic usually drone on about a “carbon budget” ...

C40 Mayors agree to bold and concrete actions to meet Paris Agreement

Posted by Maria Spiliotopoulou on Thursday, January 5, 2017, In : Climate change 
From: buildup.eu

One year after the critical Paris Climate Agreement, global mayors from the world’s megacities met in Mexico City from 30 November to 2 December 2016 at the C40 Mayors Summit to commit to turn the climate deal agreed by nation states from aspiration to action.

The mayors welcomed Anne Hidalgo, Mayor of Paris, as the group’s new chair and discussed findings from Deadline 2020: How Cities Will Get the Job Done, the critical research released by C40 in partnership with Arup. A...

Fate of Earth’s Ice Comes Further Into Focus

Posted by Maria Spiliotopoulou on Sunday, January 4, 2015, In : Climate change 
HAPPY NEW YEAR!! 2015 is here and more effort is needed for our planet to survive (with us on it!).

Reproduced from The Climate Central. By Andrea Thompson.

The frigid, ice-covered expanses that make up Earth’s poles are some of the fastest warming parts of the planet as human activity drives up greenhouse gas levels in the atmosphere, altering the global climate.

What happens to all that ice isn’t just a concern for these remote, frozen wilds: The ice sheets that cover Greenland and Antarc...

Lessons for Climate Change in the 2008 Recession

An interesting (and not so impartial) outlook on climate change, by Henry M. Paulson Jr., former US Secretary of the Treasury; reproduced from the New York Times online.

There is a time for weighing evidence and a time for acting. And if there’s one thing I’ve learned throughout my work in finance, government and conservation, it is to act before problems become too big to manage

For too many years, we failed to rein in the excesses building up in the nation’s financial markets. When ...

WHO: 7 million premature deaths annually linked to air pollution

Posted by Maria Spiliotopoulou on Thursday, March 27, 2014, In : Global 
25 MARCH 2014 | GENEVA
In new estimates released today, the World Health Organization reports that in 2012 around 7 million people died - one in eight of total global deaths – as a result of air pollution exposure. This finding more than doubles previous estimates and confirms that air pollution is now the world’s largest single environmental health risk. Reducing air pollution could save millions of lives.

New estimates

In particular, the new data reveal a stronger link between both indoor ...

Volcanic eruptions may cause global warming slowdown (new study)

Posted by Maria Spiliotopoulou on Tuesday, February 25, 2014, In : Climate change 

=> article reproduced from Reuters and The Guardian (24 Feb. 2014).

Small volcanic eruptions help explain a hiatus in global warming this century by dimming sunlight and offsetting a rise in emissions of heat-trapping gases to record highs, a study showed on Sunday.

Eruptions of at least 17 volcanoes since 2000, including Nabro in Eritrea, Kasatochi in Alaska and Merapi in Indonesia, ejected sulphur whose sun-blocking effect had been largely ignored until now by climate scientists, it said.

Six decades of warming earth (a 14'' NASA video)

Posted by Maria Spiliotopoulou on Sunday, February 2, 2014, In : Climate change 
This visualization shows how global temperatures have risen from 1950 through the end of 2013. Global warming is indeed happening. Time to face it and do our part to prevent it from continuing so.




NASA scientists say 2013 tied for the seventh warmest of any year since 1880, continuing a long-term trend of rising global temperatures. With the exception of 1998, the 10 warmest years in the 133-year record all have occurred since 2000, with 2010 and 2005 ranking as the hottest years on record.

Does suburbanization undermine greenhouse gas benefits of urban population density?

Posted by Maria Spiliotopoulou on Tuesday, January 21, 2014, In : Energy & Sustainability 
This is a brief presentation of a new study on suburbanization and carbon footprint in dense cities. I read it on Pando.sc and, although I don't have access to the full journal article, I think that these results are very important in terms of sustainable development of urban areas. We shouldn't however jump to opposite conclusions ("what? now they tell us to build high and densely?"), because obviously sustainable city dwelling doesn't correspond to what we see in many cities such as Athens ...

4 News Outlets Ban Climate Change Deniers

By Kevin Mathews, on ecowatch.com.

If a climate change denier has no place to voice his opinion, does he still make a sound?

Earlier this year, Care2 writer Beth Buczynski debated the merits of publications eliminating the opinions of climate skeptics from their pages. On the one hand, it never seems right to stifle discussion, but on the other hand, is there a point where the facts are so overwhelming and the consequences so catastrophic that it’s tim...

Should we turn deserts into carbon-sucking tree plantations?

Posted by Maria Spiliotopoulou on Wednesday, August 21, 2013, In : Climate change 
Not all scientists agree that planting more and more trees can help with the climate change and CO2 problems, but here is an interesting idea about tree planting in deserts, presented at grist.org by John Upton.


To fight climate change, some scientists think we should vegetate the hell out of deserts. The latest such idea calls for large plantations of a hardy species of Central American tree to be planted in near-coastal desert areas and irrigated with desalinated water.

While forests soak up ...

Climate change is happening too quickly for species to adapt!

Another interesting study on climate change impacts on biodiversity!
Here is the article from the Guardian, published on July 14, 2013.

Among the many strange mantras repeated by climate change deniers is the claim that even in an overheated, climate-altered planet, animals and plants will still survive by adapting to global warming. Corals, trees, birds, mammals and butterflies are already changing to the routine reality of global warming, it is argued.

Certainly, countless species have adapted...

Forests, health and climate change: what is the way forward?

Posted by Maria Spiliotopoulou on Tuesday, July 2, 2013, In : Climate change 

Forests are essential to our survival and well-being. Forests clean our air, our water, our soil and they regulate our climate, amongst many other things. Trees and forests are not always associated with urban landscapes. However, there too they provide invaluable, often invisible, services. Simply by acting as 'green oasis' in our concrete jungles, they offer recreation and health services for many European citizens.

How many of us love strolling through parks and green spaces in cities, te...
