Greenland lost a trillion tonnes of ice

While it is undeniable that the fight against climate change is ramping up, slowly but surely, rising temperatures and environmental degradation are getting scarier each month. An example among others was how Greenland lost one trillion tons of ice in just three years.

Climate change to make Middle East and North Africa unhabitable

Here is another scary climate change story: according to a new study, the Middle East and North African regions could become unhabitable by 2050 because of rising temperatures.

World hunger keeps on decreasing

What if we were actually on the right track to solve world hunger ? The UN FAO has published a report recently stating that there are 200 million hungry people less than in 1990, all this while global population increased.

IPCC fifth report is a stark warning

IPCC AR5 WG2As you perhaps know, the Intergovernmental Panel on Climate Change (IPCC) is publishing in 2014 its fifth Assessment Report. If the fourth, published in 2007, was a strong warning against business as usual, the latest one is even more serious.

Today the Working Group II considered ” the vulnerability and exposure of human and natural systems, the observed impacts and future risks of climate change, and the potential for and limits to adaptation. “

The findings are really scary and should – hopefully will – urge our governments towards more drastic and faster action towards greenhouse gases emissions reduction.

2013 was one of the warmest years since 1880

NASA 2013 annual temperature anomaliesBoth NASA and NOAA – US National Oceanic and Atmospheric Administration – have issued a joint presentation on how climate change made 2013 one of the warmest year ever recorded.

It is worth showing to any climate change deniers you may know. According to NASA : ” NASA scientists say 2013 tied with 2009 and 2006 for the seventh warmest year since 1880, continuing a long-term trend of rising global temperatures. “

” With the exception of 1998, the 10 warmest years in the 134-year record have all occurred since 2000, with 2010 and 2005 ranking as the warmest years on record “

Climate change endangers Winter Olympics

Sochi 2014As you know, the Russian city of Sochi is the host of the Winter Olympics since Friday. According to a brand new study, this might be the right time as it is most probable the city won’t be able to do so in the future because of climate change.

According to the climatologists from the University of Waterloo, Canada : ” Only six of the previous Winter Olympics host cities will be cold enough to reliably host the Games by the end of this century if global warming projections prove accurate ”

Even artificial snow making won’t be enough to provide snow for Winter Olympics by mid-century if rising temperatures were to continue unabated.

Stunner : carbon dioxide role known as early as 1932

While vested interests are still denying the warming role in our atmosphere of carbon dioxide, TreeHugger has unearthed a study from early as 1932 showing that this gas is actually warming our Planet. This was 81 years ago ! I had heard or rather read that this was known from at least since the 1980s … Read more

Soot’s underestimated role in climate change

Soot, aka black carbonAccording to the most comprehensive research on the subject, soot – also known as black carbon – may have a significantly higher role in climate change than previously estimated.

According to a BBC article quoting the study : ” (soot) dark particles are having a warming effect approximately two thirds that of carbon dioxide, and greater than methane. “

Tackling its emissions – which come mostly from wood and coal burning as well as diesel engines in developed countries – would be easy to tackle.

Are our cities just too big to flood ?

Flood in BangkokThis was the question asked on the the Yale Environment 360 blog and I believe the timing is perfect as last year cities such as New York City, Manila and Bangkok got it by record floods. Now it is the turn of Jakarta.

The capital megacity of Indonesia now has water in its streets and people to evacuate because of another flood. Given that rising temperatures mean rising sea levels and more extreme weather, the threat is huge.

First in terms of people – as the majority of people will live in cities in 2050 and as 14 of the world’s 17 largest cities are located along coasts.

Hopefully I won’t be late for the selection of tweets next month. Nota : the layout is broken. Nonetheless, the tweets are readable. Sorry for the inconvenience.

Global emissions need to peak before 2015-2020

As TreeHugger reports :emissions must peak by 2020 and be reduced “well below” 1990 levels by 2050, if we are to have a “likely” (greater than 66%) chance of keeping temperature rise below 2°C by 2100. “

” If emissions peak at 2030, we may be able to hold temperature rise to 3°C. Should emissions continue on a business-as-usual trajectory, sometime between 2040-2060 we will cross the 2°C threshold. “

I had read once that they needed to peak by 2015. I also noted previously that even a mere 2°C might be too much for all of us as carbon sinks are becoming less efficient.
