Big Scientific Development

 The Sun did do it!

We do not know what actually causes the Earth’s temperature to vary.
It does vary – ice ages and little ice ages and warm periods are in the record.
Radioctive decay in our molten core radiates heat out through the surface and generates a powerful magnetic field which protects our rich atmosphere from the solar wind and radiation. There may be a cycle to this effect.
The Earth’s axis wobbles like a spining Top and the orbit varies in shape. This may effect the temperature.
Volcanos regularly erupt with a planetary effect.
Large comets and asteroids impacts also have a planetary effect.
Humans also now have a small effect with the dust and particulates from our artificial burning of fuels.
The Earth we live in, the last kilometer of the crust, is 70% water which absorbs a lot of heat while the land absorbs very little, because it does not circulate like water. If you look at the planet from outer space you will see that there is a constant, chaotic, churning equilibrium between evaporation at the warm surface and condensation at the freezing cold vacuum of space, which forms white clouds of condensation in-between.
On a short term basis this system is very stable and self-regulating. Disturbances like volcanos or impacts are quickly smoothed out and we return to normal.
So why does the planet suddenly expand its icecaps or slowly get warmer and dryer?

Cosmic Rays.
There is a statistical nexus between sunspots, solar activity, and the Earth’s temperature. This is not fully explained by the actual associated rise in heat output of the star, which is very small. So why?
Cosmic Rays are not actually “rays” like heat and light and radio rays –  they are very fast moving atomic nuclei, striking Earth from outer space.
It has been speculated that cosmic rays are the main influence on the Earth’s temperature and climate in that they “seed” cloud formation. (clouds need small impurities to form on).
Clouds formed on cosmic ray nuclei reflect heat to outer space.

This theory attributes long term variation in our planet’s climate to variations in the cosmic ray flux and short term variation in the Earth’s temperature to the emissions from solar flares because they effect this cosmic ray flux.
Recently, the effect of cosmic ray cloud seeding was demonstrated in the laboratory.
(Here –

Now this brilliant new paper establishes the actual variation in cosmic rays in our part of the galaxy and thus provides a powerful connection between the previous variations in cosmic rays and the observed historical cycles in the Earth’s temperature and climate.

Notes for editors
Prof. Henrik Svensmark leads the Center for Sun-Climate Research at the National Space Institute in the Technical University of Denmark (DTU). He has authored or co-authored 20 papers exploring the influence of cosmic rays, which come from supernova remnants, on the Earth’s cloudiness.   More information is available on the DTU Sun-Climate website
