Два кључна показатеља климатских промена – глобалне површинске температуре и количина арктичког леда – су оборили низ рекорда у првој половини 2016., према анализама NASA на основу опажања на Земљи и сателитски података
Сваки од првих шест месеци 2016 је поставио рекорд као глобално најтоплији од када се врше температурна мерења, од 1880 године, како наводе научници NASA Годар института за свемирска исраживања [NASA's Goddard Institute for Space Studies (GISS)] у Њујорку. Период од шест месеци, од јануара до јуна, је такође био најтоплији планетарни полугодишњи рекорд, са вишим просечним температурама од 1.3 степена Целзијуса (2.4 степена Фаренхајта) поредећи са XIX веком.

Сваки од првих шест месеци 2016 је поставио рекорд као глобално најтоплији поредећи са свим досадашњим температурним мерењима, која датују од 1880 године. Пет од шест месеци су, такође, поставили рекорде са најмањим месечним површинама леда на Арктику од када су ова стална сателитска праћења започела 1979 године.

ARE WE IN SERIOUS TROUBLE - THE WARMEST YEAR SINCE 1880

2016 Climate Trends Break Records

Two key climate change indicators -- global surface temperatures and Arctic sea ice extent -- have broken numerous records through the first half of 2016, according to NASA analyses of ground-based observations and satellite data.
Each of the first six months of 2016 set a record as the warmest respective month globally in the modern temperature record, which dates to 1880, according to scientists at NASA's Goddard Institute for Space Studies (GISS) in New York. The six-month period from January to June was also the planet's warmest half-year on record, with an average temperature 1.3 degrees Celsius (2.4 degrees Fahrenheit) warmer than the late nineteenth century.

Each of the first six months of 2016 set a record as the warmest respective month globally in the modern temperature record, which dates to 1880. Meanwhile, five of the first six months set records for the smallest monthly Arctic sea ice extent since consistent satellite records began in 1979.

THE SCIENCE RUNS FOR THE BORDER - NEW RESEARCH IN SPACE

First DNA Sequencing in Space
a Game Changer

For the first time ever, DNA was successfully sequenced in microgravity as part of the Biomolecule Sequencer experiment performed by NASA astronaut Kate Rubins this weekend aboard the International Space Station. The ability to sequence the DNA of living organisms in space opens a whole new world of scientific and medical possibilities. Scientists consider it a game changer.
DNA, or deoxyribonucleic acid, contains the instructions each cell in an organism on Earth needs to live. These instructions are represented by the letters A, G, C and T, which stand for the four chemical bases of DNA, adenine, guanine, cytosine, and thymine. Both the number and arrangement of these bases differ among organisms, so their order, or sequence, can be used to identify a specific organism.
