The albedo is defined as the fraction of sunlight that the Earth reflects back directly into space, and it varies according to cloud composition, ice, snow, and the nature of the surface onto which the sun’s rays fall.

Thank you scientist’s for the good news.Your awesumness is greatly appreciated.

Nearly all of the energy arriving on planet Earth and driving the various weather events, oceanic currents, and distribution of ecosystems originates with the sun. This intense solar radiation as it is known in physical geography originates in the sun’s core and is eventually sent to Earth after convection (the vertical movement of energy) forces it away from the sun’s core. It takes approximately eight minutes for solar radiation to reach the Earth after leaving the sun’s surface.

Once this solar radiation arrives on Earth, its energy is distributed unevenly across the globe by latitude. As this radiation enters the Earth’s atmosphere it hits near the equator and develops an energy surplus. Because less direct solar radiation arrives at the poles, they in turn develop an energy deficit. To keep energy balanced on the Earth’s surface, the excess energy from the equatorial regions flows toward the poles in a cycle so energy will be balanced across the globe.

Climate Change: Vital Signs of the Planet: News

Many very interesting NASA articles at the link below.

This is just a sample of some very interesting reading on Earth systems and  major shifts.
Let’s do our research and get the facts straight.

Expanding tropics are pushing high altitude clouds towards poles.

A new NASA analysis of 30-years of satellite data suggests that a previously observed trend of high altitude clouds in the mid-latitudes shifting toward the poles is caused primarily by the expansion of the tropics.

Clouds are among the most important mediators of heat reaching Earth’s surface. Where clouds are absent, darker surfaces like the ocean or vegetated land absorb heat, but where clouds occur, their white tops reflect incoming sunlight away, which can cause a cooling effect on Earth’s surface. Where and how the distribution of cloud patterns change strongly affects Earth’s climate. Understanding the underlying causes of cloud migration will allow researchers to better predict how they may affect Earth’s climate in the future.

How cheap does solar power need to get before it takes over the world? – Vox

http://www.vox.com/2016/4/18/11415510/solar-power-costs-innovation

I was curious to hear reactions to Sivaram and Kann’s argument, so I ran it by (among others) Justin Baca, the vice president for markets and research at the Solar Energy Industries Association, the main trade group for the solar industry.

By and large, he agreed that value deflation was a real issue, although he thought the paper downplayed some of the ways we might ultimately solve it. For instance, if countries electrify their vehicle fleets, that could create a massive new outlet for solar electricity during the day.

Importantly, Baca also pointed out that many US electricity markets remain heavily regulated, and are likely to be for many years to come. In those regulated grid systems, solar could end up being shielded somewhat from declining wholesale prices. (Though, again, value deflation would happen regardless — and would make any regulations more costly over time.)

Yes, solar is getting cheaper. But it needs to pick up the pace.

“Okay, wait,” you might be thinking. “Isn’t solar already getting cheaper?” Yes and no.

It’s true that over the past five years, the cost of crystalline silicon photovoltaic panels — the current solar technology of choice — has fallen 80 percent, as China has ramped up manufacturing and the efficiency of cells improves incrementally. In the US, the price of installed utility-scale solar has dropped from $6 per watt in 2007 to around $3 per watt in 2014.

Severe Weather Technology

Tuesday, May 3, 2016, 3:04 PM – NASA researchers have just given severe weather forecasters a powerful new tool in the detection of hazardous storm conditions on the ground, by focusing their attention on the storms’ loftiest heights.

NASA has already been gaining new insights into storms by scanning the rain content of clouds from space, but a new line of research is showing how the tops of clouds could reveal important details about what’s going on underneath them.

Kristopher Bedka, a physical scientist at NASA’s Langley Research Center, is leading a team that has developed a new method for computers to scan thousands of square kilometres of imagery from orbiting weather satellites in under two minutes, to pick out an indicator of extreme weather known as overshooting tops.

Will a developing La Niña affect our summer as much as El Niño affected our winter?
