How and Why U. Greenhouse Gas Emissions Are Falling Recent data clarify the trends causing emissions to shrink to their lowest level since Greenhouse gas emissions in the United States fell to their lowest level in 17 years in , according to a new report from the Environmental Protection Agency. Additional data from the U. The picture is less encouraging globally. Although a report by Reuters shows that greenhouse gas emissions in industrialized nations fell by 1.

Article Recommendations Abstract Thermoluminescence TL dating is a valuable tool for chronometric dating of heated minerals and has been shown to agree very well with independent age control. Comparison with argon dating of samples from identical events, however, revealed age underestimations of volcanic eruptions dated by orange-red TL R-TL of quartz extracts from some xenolith samples, while good agreement was obtained for others. While the data is not entirely conclusive, it leads to the current working hypothesis that exposure to high temperatures might be responsible for an effect similar to the anomalous fading phenomena observed for some feldspar luminescence.
It therefore appears to be prudent not to sample xenoliths from high temperature context, like basalt dykes in volcanic context. An investigation of pulsed-irradiation regeneration of quartz OSL and its implications for the precision and accuracy of optical dating Paper II.

The show’s debut received largely harsh reviews; The New York Times described it as “dizzyingly absurd” and The Washington Post denounced it as “the trashiest stab at candycane journalism yet. A Memoir, Roone Arledge recalled that probably the most embarrassing part of that initial program was the Claymation segments featuring caricatures representing then-President Jimmy Carter singing ” Georgia on My Mind ” and Walter Cronkite closing the show intoning, “That’s the way it was”.
As a result of the scathing reviews, serious and drastic changes were immediately made: Hayes and Hughes were fired as was original executive producer Bob Shanks , and a then semi-retired Hugh Downs was recruited to take on the role of sole host on the following week’s program. The program was originally launched as a summer replacement series; it was then presented on a once-a-month basis during the —79 television season, before being given a regular weekly timeslot on Thursdays at Eastern Time beginning May 31, It was around this time that the program started using the Brock Brower-written signoff line “We’re in touch, so you be in touch” to end each program,  which continues to be used to now the program also used the line “Around the world and into your home, the stories that touch your life” as the introduction during the show’s opening titles for much of the s.
Barbara Walters joined the program in in a role something less than a co-anchor and soon became a regular special contributor in the fall of In , she became Hugh Downs’s equal, thus reuniting a duo which had already anchored together on NBC’s Today from to The team would remain together on-air for the next 15 years.

Share 40 shares ‘This is a window into the future. We need to reach a peak in global emissions in the next few years and drive emissions down rapidly afterwards to address climate change and limit its impacts. According to the Global Carbon Budget , carbon dioxide emissions from fossil fuels and industry are projected to grow by 2 per cent this year, following three years of nearly no growth.
Experts found the plateau of last year was not peak emissions after all. The amount of carbon dioxide in the Earth’s atmosphere grew at a record rate in to a level not seen for millions of years, the United Nations revealed last month.

Blog home Carbon emissions per person, by country Looking at a country’s total carbon emissions alone doesn’t tell the full story of the country’s contribution to global warming Roll over the lines to get the data. Looking at a country’s total carbon emissions doesn’t tell the full story of a country’s contribution to global warming. China, for example, is the world “leader” in total emissions m metric tonnes of carbon dioxide since it overtook the US in But all that really tells you is that China is a fast-developing country with a lot of people.
A more useful measurement is carbon emissions per capita person. Under that measurement, the average American is responsible for Examining CO2 per capita around the world also shows us the gulf between the developed world’s responsibility for climate change and that of the developing world. While Australia is on Poorer African nations such as Kenya are on an order magnitude less again — the average Kenyan has a footprint of just 0.

Car sales slumped across Europe in September, industry data published Wednesday showed, with the hangover from a sales binge before new emissions tests came into force knocking Volkswagen out of its traditional top spot in monthly sales.
By Parth Vaishnav , Iddo K. Wernick International transport, which includes ocean shipping and aviation, is among the fastest-growing sources of human-generated greenhouse gas emissions. Between and , carbon dioxide CO2 emissions from international transport grew faster— I at 7 and 6. Although was a year of especially rapid growth as global trade and travel bounced back from the recession, emissions from this activity are expected to grow to between two and three times their current level by This growth will start from a small but substantial base: If the sector were a country, its current emissions would be roughly the size of those of Japan or Germany.
Rising emissions from international transport could dilute hard-won reductions in other sectors, such as the switch from coal to wind and solar electricity. To see how, consider the case of the United Kingdom. In , it emitted about million tons of CO2. The United Kingdom has instituted a legally binding commitment to reduce its annual greenhouse gas emissions in to one-fifth of their level in This means that in , the United Kingdom ought to emit a mere million tons of CO2. The unchecked growth of emissions from transport is therefore inconsistent with the drastic reduction in the overall production of greenhouse gases that is required to forestall dangerous climate change.
Given the nature of global transport, it is difficult to allocate its environmental impacts to any one country.

New emission tests brake EU car sales in September 17th October , 0 comments Car sales slumped across Europe in September, industry data published Wednesday showed, with the hangover from a sales binge before new emissions tests came into force knocking Volkswagen out of its traditional top spot in monthly sales. Sales had jumped by nearly a third in August, traditionally a soft month for car sales as many Europeans are on vacation, as carmakers discounted vehicles that hadn’t been certified using the new WLTP test.
The new EU-wide test procedure is one front of authorities’ reaction to VW’s admission to mass cheating on diesel vehicles, with suspicions since spreading to other manufacturers. Wolfsburg-based VW manipulated 11 million cars worldwide to meet limits for emissions of harmful nitrogen oxides NOx under lab conditions. In real on-road driving, they spewed many times the allowed amounts of the harmful gases — which the World Health Organization WHO says aggravate asthma and bronchitis symptoms and are linked to cardiovascular and respiratory disease.
In the event, VW — Europe’s largest car group by sales volume — was the hardest hit by the introduction of the new tests.

Now you know the year of production, you need to find the day and month: From August , VW fixed a production plate which holds the information you need for the next step. The Air-cooled Production Plate This plate is found on Beetles, Type 3s and Type 4s on the front panel near the chassis plate, but painted in the body colour.
It gives the production date as the week of the calendar year, and the weekday. Thus this car was made on Monday, Week 18 a calendar lets you work out the actual date. Its factory colour code is 21, which is Marina blue shown in brochures.

Summary[ edit ] The Coneheads are an alien family, natives of the planet Remulak, who find themselves stranded on Earth. The Coneheads’ most distinguishing feature is that, as their name implies, the tops of their heads are shaped like large cones. It is unclear if “Conehead” is the name of their race or just their surname , but in their interactions with humans, it is used in the latter sense. When questioned by Earth neighbors as to their strange behavior, they invariably reply that they are from France , Remulak being the purported name of their home village.
With the exception of Agent Seedling and his assistant in the feature-length version , they are never suspected of being extraterrestrial aliens by anyone who encounters them, even when accidentally referring to their neighbors as “Earthlings”. Much of the humor is derived from this clash between their odd behavior and appearance, and the casual acceptance of the Coneheads by those they encounter.

A number of other manufacturers used internal EGR. Ammonia-SCR is an important competing technology. The introduction of EGR technology to diesel passenger cars in the s went almost unnoticed and was not considered a major breakthrough for several reasons. Typical passenger car engines operate mostly at part load conditions where temperatures are relatively low. The wide scale launch of cooled EGR on heavy-duty engines that attracted a lot of attention to the technology took place in late in the North American market.
High pressure loop cooled EGR was the most expedient in-cylinder NOx reduction technology that could achieve this emission level [ ]. There was a considerable apprehension in the field regarding the performance, fuel economy, and the durability of these new engines. While initial statements from fleet managers appeared to praise the new technology [ ] , some users have complained of the increase in fuel consumption.
