Hola amigos: A VUELO DE UN QUINDE EL BLOG., hemos recibido información de la Agencia Espacial NASA, sobre que la: The National Oceanic and Atmospheric Administration (NOAA) , ha encontrado el clima más cálido durante el año 2014 como un recordó en tiempos modernos; el año 2014 filas como la de la Tierra más caliente desde 1880, de acuerdo con dos análisis separados por los científicos de la NASA y la Administración Nacional Oceánica y Atmosférica (NOAA).
Los 10 años más cálidos en el registro instrumental, con la excepción de 1998, ahora se han producido desde el año 2000. Esta tendencia continúa el calentamiento a largo plazo del planeta, según un análisis de las mediciones de temperatura superficial por los científicos de: NASA’s Goddard Institute of Space Studies (GISS) in New York.
En un análisis independiente de los datos en bruto, también difundido el viernes, científicos de la NOAA también encontraron 2014 para ser el más cálido registrado.

The year 2014 ranks as Earth’s warmest since 1880, according to two separate
analyses by NASA and National Oceanic and Atmospheric Administration (NOAA)
scientists.
The 10 warmest years in the instrumental record, with the exception of 1998,
have now occurred since 2000. This trend continues a long-term warming of the
planet, according to an analysis of surface temperature measurements by
scientists at NASA’s Goddard Institute of Space Studies (GISS) in New York.
In an independent analysis of the raw data, also released Friday, NOAA
scientists also found 2014 to be the warmest on record.
“NASA is at the forefront of the scientific investigation of the dynamics of
the Earth’s climate on a global scale,” said John Grunsfeld, associate
administrator for the Science Mission Directorate at NASA Headquarters in
Washington. “The observed long-term warming trend and the ranking of 2014 as the
warmest year on record reinforces the importance for NASA to study Earth as a
complete system, and particularly to understand the role and impacts of human
activity.”

Since 1880, Earth’s average surface temperature has warmed by about 1.4
degrees Fahrenheit (0.8 degrees Celsius), a trend that is largely driven by the
increase in carbon dioxide and other human emissions into the planet’s
atmosphere. The majority of that warming has occurred in the past three
decades.
“This is the latest in a series of warm years, in a series of warm decades.
While the ranking of individual years can be affected by chaotic weather
patterns, the long-term trends are attributable to drivers of climate change
that right now are dominated by human emissions of greenhouse gases,” said GISS
Director Gavin Schmidt.
While 2014 temperatures continue the planet’s long-term warming trend,
scientists still expect to see year-to-year fluctuations in average global
temperature caused by phenomena such as El Niño or La Niña. These phenomena warm
or cool the tropical Pacific and are thought to have played a role in the
flattening of the long-term warming trend over the past 15 years. However,
2014’s record warmth occurred during an El Niño-neutral year.
“NOAA provides decision makers with timely and trusted science-based
information about our changing world,” said Richard Spinrad, NOAA chief
scientist. “As we monitor changes in our climate, demand for the environmental
intelligence NOAA provides is only growing. It's critical that we continue to
work with our partners, like NASA, to observe these changes and to provide the
information communities need to build resiliency.”
Regional differences in temperature are more strongly affected by weather
dynamics than the global mean. For example, in the U.S. in 2014, parts of the
Midwest and East Coast were unusually cool, while Alaska and three western
states – California, Arizona and Nevada – experienced their warmest year on
record, according to NOAA.
The GISS analysis incorporates surface temperature measurements from 6,300
weather stations, ship- and buoy-based observations of sea surface temperatures,
and temperature measurements from Antarctic research stations. This raw data is
analyzed using an algorithm that takes into account the varied spacing of
temperature stations around the globe and urban heating effects that could skew
the calculation. The result is an estimate of the global average temperature
difference from a baseline period of 1951 to 1980.
NOAA scientists used much of the same raw temperature data, but a different
baseline period. They also employ their own methods to estimate global
temperatures.
GISS is a NASA laboratory managed by the Earth Sciences Division of the
agency’s Goddard Space Flight Center, in Greenbelt, Maryland. The laboratory is
affiliated with Columbia University’s Earth Institute and School of Engineering
and Applied Science in New York.
NASA monitors Earth's vital signs from land, air and space with a fleet of
satellites, as well as airborne and ground-based observation campaigns. NASA
develops new ways to observe and study Earth's interconnected natural systems
with long-term data records and computer analysis tools to better see how our
planet is changing. The agency shares this unique knowledge with the global
community and works with institutions in the United States and around the world
that contribute to understanding and protecting our home planet.
