Fabio Bergamin, ETH Zurich The average temperature on Earth has barely risen over the past 16 years. ETH researchers have now found out why. And they believe that global warming is likely to continue again soon. Global warming is currently taking a break: whereas global temperatures rose drastically into the late 1990s, the global average temperature has risen only slightly since 1998 – surprising, considering scientific climate models predicted considerable warming due to rising...

Does Solar Activity Have Influence On Earth's Global Warming?
2014-06-06 03:12:26

Science China Press A recent study demonstrates the existence of significant resonance cycles and high correlations between solar activity and the Earth's averaged surface temperature during centuries. This provides a new clue to reveal the phenomenon of global warming in recent years. Their work, entitled "Periodicities of solar activity and the surface temperature variation of the Earth and their correlations" was published in CHINESE SCIENCE BULLETIN (In Chinese) 2014 No.14 with the...

North Atlantic Climate Variability Influenced By Solar Activity
2014-03-11 08:11:32

redOrbit Staff & Wire Reports - Your Universe Online A 1,000-year period of pronounced climate variability occurring in Europe could have been the result of changes in the sun’s energy output, according to research published in Sunday’s edition of the journal Nature Geoscience. In the study, lead author Dr. Paola Moffa-Sanchez of the Cardiff University School of Earth and Ocean Sciences and her colleagues studied seafloor sediments to uncover changes to the temperature and...

Solar Activity Little Effect On Climate
2013-12-23 10:45:26

Brett Smith for redOrbit.com - Your Universe Online From the Medieval Climate Anomaly to the Little Ice Age, average temperatures on Earth have varied significantly over the past thousand years. And according to a new study in Nature Geoscience that variation has little to do the amount of activity from the Sun. The Medieval Climate Anomaly, which lasted from approximately 950 to 1250, was a warming period in certain regions. The Little Ice Age, which lasted from about 1450 to 1850, is...

New Instrument Continues To Gather Effects Of The Sun On Earth
2013-12-05 15:56:22

NASA Maintaining a record of solar measurements is important in understanding the sun's effect on Earth and the National Oceanic and Atmospheric Administration's (NOAA), Total solar irradiance Calibration Transfer Experiment, or TCTE, is now providing that information. Many natural conditions on Earth such as the surface temperature or air temperature depend on energy that comes from the sun in the form of electromagnetic radiation. A solar cycle lasts about 11 years and typically has...

Powering The SUn's Atmosphere
2013-11-15 09:30:08

John P. Millis, PhD for redOrbit.com - Your Universe Online The core of the Sun is a nuclear furnace, burning at 15 million degrees Kelvin. This heat travels to the surface, creating surface plasma that is still a balmy 6,000 Kelvin. However, a strange thing happens above the surface of the Sun; in the solar atmosphere, known as the corona, temperatures can exceed a million degrees Kelvin. Researchers have long suspected that the cause for this dramatic heating is due to interactions...

Weather Balloon Helps Measure Earth's Reflectivity
2013-11-01 04:20:18

Lee Rannals for redOrbit.com - Your Universe Online The amount of sunlight reflecting off of Earth’s atmosphere is a key measurement for better understanding climate change, and weather balloons could help advance data collection techniques even more. NASA’s Earth Science Technology Office is supporting the development of the HyperSpectral Imager for Climate Science (HySICS). This instrument made its inaugural engineering balloon flight at the end of September, providing realistic,...

Science Experiment Requires New Altitude For Space Station
2013-07-02 10:44:28

Lee Rannals for redOrbit.com - Your Universe Online Crew members aboard the International Space Station (ISS) had to add a little more distance between the orbiting laboratory and Earth on Sunday for a science experiment. NASA said astronauts raised the space station's altitude to accommodate a research project aimed at learning about Earth's atmosphere and climate change. "The European scientists requested that we reposition the station slightly because by having this period of time...

Climate Study Finds Earth Is Warmer Than At Any Time In Past 1,400 Years
2013-04-22 13:01:02

Lee Rannals for redOrbit.com — Your Universe Online Another study is backing up climate change claims, saying Earth is at the warmest it has been in at least 1,400 years. The study shows that the planet has warmed more between 1971 and 2000 than during any other three-decade interval during the model period. "This paper tells us what we already knew, except in a better, more comprehensive fashion," study co-author Edward Cook, a tree-ring scientist at Lamont-Doherty Earth...

Our ℠Blue Dot´ is adrift in a cosmic soup of powerful solar winds, magnetic fields, and cosmic rays; even the Vatican Observatory has studied the heavens for hundreds of years. Climate change focus on global warming and carbon dioxide (CO2) is near-sighted, causing wasteful climate policies that have pushed millions into a “heat or eat poverty crisis” that is based on faulty science. Calgary, Alberta, Canada (PRWEB) March 22, 2013 Earth Hour purports to unite people...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...

Incoming Solar Radiation Impacts By Various Weather Cycles

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Honolulu Hawaii, during the month of March. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 48% efficient for the month, producing less than 50% of the month which is due to the large amount of daily cloud cover that is seen on the island during the early morning and...

Being a meteorologist for over thirteen years you start to take note of many things in the atmosphere and how they repeat themselves. Our Climate is no different. The definition of climate is stated as: the collective weather data in regards to moisture and temperature for over 30 years for the same location. So to better understand our climate we need to look at this. First, we have average temperatures for given places based on the 30 year average. Some years the temps are warmer or...

Incoming Solar Radiation Impacts By Various Weather Cycles

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Austin Texas. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 60% efficient for the month, producing enough solar energy that only 40% of the month would have not had strong incoming radiation. EL-Nino: This phase provided the area with an extended number of...

Charles Greeley Abbot (May 31, 1872 "“ December 17, 1973) was an American astrophysicist and astronomer born in Wilton, New Hampshire. He graduated from Phillips Academy in 1891 and MIT in 1894, with a degree in chemical physics. In 1895 Abbot was hired by Samuel Pierpont Langley as an assistant at the Smithsonian Astrophysical Observatory (SAO) despite his lack of experience in astronomy. Hired originally for his laboratory skills, Abbot became acting director of the SAO in 1896. When...
