Eighth historical minimum for the Arctic ices

By | Notizie | No Comments
The National Snow & Ice Data Center (NSIDC) reiterates it in the premise of its announcement: changing wind or a late warm season are still possible (events that already occurred in 2005 and 2010) to vary the minimum ice extension at the end of the Arctic summer. For this reason, official data will only be communicated in October. The 13th September result at the moment to have recorded the seasonal minimum extension, with a reduction of 4.64 million km2, the eighth lowest in the 38-year satellite record of Arctic ice extension. It should also be noted that the overall rate of ice loss this summer was slowed by a persistent pattern of low sea level pressure, focused over the central...

A connection between Irma hurricane and climate change?

By | Notizie | No Comments

It is a difficult question, though inevitable to ask ourselves. A recent New York Times article opens with a simple consideration. Having a warmer atmosphere is equivalent to allowing the accumulation of more moisture in the air and consequently releasing more water as precipatations. The image contained in the article, correlating the temperature pattern and the frequency of extreme rain that hit the USA since the early 1900s does not need any further comment on it. “There is overwhelming evidence that climate change is altering the weather. Irma and Harvey weren’t caused by climate change, but they almost certainly would not have been so powerful if the air and the seas fueling them hadn’t been so warm”. The article continues…

Only one year to complete the adaptation to the ISO 14001:2015 standard

By | Notizie | No Comments

Last turning point to adapt to the new standards on Environmental Management System (EMS) ISO 14001:2015. According to certifiers’ data, only a small number of companies have completed this important transition, while many companies seems to have not yet paid enough attention to the transition. It is important to remember that it is a substantial change, not comparable with the minor aspects introduced with the 2004 version. It is therefore not neglegible the risk for the companies not to successfully complete the transition within the leatest deadline of September 15th, 2018. Meanwhile, two important novelties will be discussed today in Milan within the UNI National mirror group on EMS (GL1) coordinated by Daniele Pernigotti. The first is the publication of…

It’s time for training on ETS directive

By | Notizie | No Comments

South Korea has long developed its own national ETS scheme (KETS), currently under revision. The objective is also to increase its compatibility with the European scheme, in order to foster the creation of a single international carbon trading platform. In this regard, an important workshop was held last week in Seoul with the various stakeholders who manage the various aspects of KETS. Daniele Pernigotti and English verifier have also attended the meeting, in order to share the ETS experience. This was the occasion to discuss the European accreditation system of verification bodies and recruiting of ETS verifiers in the three phases of European ETS. The training appointments at European level, however, continue also this week. Daniele Pernigotti, in fact, today…

CDP Report: more than 70% of global GHG emission is produced by 100 companies

By | Notizie | No Comments

50% of global GHG (Greenhouse Gases) emissions is produced by 25 world companies. If we consider the first 100 in the world, we cover 71% of global emissions. This is the different perspectives used by CDP (Carbon Disclosure Project), where the center is the market instead of Member States, to map the emissions responsible for anthropogenic climate change. Pedro Faria, CDP’s technical director, highlights companies’ huge role to play in driving climate change, also recognizing the “absolute tension” existing between short term profitability and the urgent need to reduce emissions. A Carbon Tracker study in 2015 found that fossil fuel companies risked wasting more than $2tn over the coming decade by pursuing coal, oil and gas projects that could be worthless in the face…

IEA: Electric car market continues to grow worldwide

By | Notizie | No Comments
In 2016 the number of electric cars in circulation reached 2 millions, still far from the number of 600 million cars that will have to circulate by 2040, which is the target indicated by IEA for the transport sector in order to stay below 2°C rise in temperature. The electric car market is driven by China, which represented 40% of global sales in 2016, but the market is already very interesting in Europe. In Norway, about a third of the cars sold in 2016 were electric and 6 European countries are among the top 10 countries in the world for this market. Among these countries Italy is not included that, among other things, has not introduced into the draft National...

Alarming signals from the Atlantic Meridional Overturning Circulation

By | Notizie | No Comments

The National Snow and Ice Data Centre reports a recent article published on Nature about the growing risk of slowing down of the Atlantic Meridional Overturning Circulation (AMOC), the ideal oceanic conveyor belt of the equator’s heat to northern Europe. It is in fact thanks to the AMOC that Amsterdam enjoys a milder winter than Winnipeg, Canada, despite being at the same latitude. The merging of Arctic ice may interrupt this current due to the introduction of large masses of cold water. These absorb part of the heat of the AMOC and can create a cap for such a circulation, based on delicate temperature-salinity balances, parameters that affect the water density and therefore the basis of the thermohaline circulation.

New York Times: Exxon Mobil contributed quietly to climate science and loudly to raising doubts about it

By | Notizie | No Comments

The New York Times has published the results of a study conducted with the support of Harvard University and the Rockefeller Family Fund, which already promoted a research on the topic of the Columbia University, published by The Los Angeles Times. The object of the controversy is well known and still under investigation by prosecutors of New York and Massachussets. Some employees and shareholders have denounced the world oil giant for fraud. The company would have been aware of the problem of climate change since the 70s and the consequent need to reduce the consumption of petroleum products, but would have sponsored mass media information in the news channels in the opposite direction. The NYT study examines 187 company documents…

Greenland’s ice melts faster than expected

By | Notizie | No Comments
Scientists show a growing concern about the state of the ice in Greenland, given the ever-faster pace it is melting. The total disappearance of these ice sheets, which are about 3 km thick, would lead to a rise of about 7 meters in the oceans, but it is certain that this extreme scenario will not come to fruition over the course of a few centuries. Today, however, the melting of Greenland ice contributes, by about 1 mm, to just under a third of the annual rise of the oceans. The new source of concern is related to the proliferation of algae populations on the ice surface, favoured by the already recorded increase in temperature. The surface of the ice thus...
