By how much does the earth`s magnetic force effect climate change,?

Question

I belive the megnetic field is becomeing weaker,

Answer 1

By how much exactly, we do not know, but there is more than ample evidence to suggest that our climate is significantly affected by the Earth's magnetic field, or rather, the interplay between the both the magnetic fields of the Sun and Earth, solar winds, and cosmic rays. In addition to the cloud formation hypothesis Jim mentioned, cosmic radiation appears to have some effect on the climate as it directly pertains to temperature. You can peruse through some of these sources, but suffice to say, the one conclusion that you can draw from this is that the debate is NOT settled, that there are many influences to global climate besides the one that alarmists want us to concentrate on.

I deliberately chose some articles because they looked at this evidence from both sides. Real science never closes debate on complex systems such as climate. It doesn't dismiss ideas as impossible when there is so obviously much we don't know about the multiple interactions combining to form the phenomena we observe.

I couldn't tell you if the Earth's magnetic field significantly affects climate - but to tell you flat out that it doesn't, is wrong.

Answer 2

Had to star you cos I've been looking into this subject for quite a long time and I agree very much with 'jim z' and with '3DM' - I disagree with 'Trevor' and 'Ivan R' who both give the conventional view.

The Earth's geomagnetic field is certainly growing weaker; this fact is well documented, and the reversal of the geomagnetic poles is anticipated within the next 1,000 years (or sooner). There are several large fluctuating anomalies in the field that are being monitored. To say that a weakening field, or zero field, or pole reversal will definitely NOT affect climate is a totally invalid claim as there's more evidence so far to show that changes in global climate did occur in the past coinciding with pole reversals that may have been due to the weak/zero field at the time of reversal.

The jury is still out r.e. whether geomagnetism is currently (or will in future) have any affect upon global climate, purely because not enough research is being done into this topic.

The best place to begin looking for an intro into all of this is Wikipedia - look up 'geomagnetism'.

Answer 3

Interestingly, this is a subject that hasn't caught on. The magnetic field protects the earth from cosmic rays. Those rays have recently been shown to cause water vapor to condense. This results in clouds. This is theoretically why the sun spot activity results in temperature swings beyond what would be expected from solar output alone. I have never heard a scientist (besides me, I am a geologist) who has suggested that the weaking field might affect the climate but I think that it might. Trevor is giving a good and mainstream view but I still think that it might affect the climate more than would be generally believed for the little understood reason provided above. You are correct that the magnetic field is weakening and therefore more cosmic rays will hit the earth. This is resulting because we apparently in the process of magnetic polar reversal which is a process taking hundreds of years. The first stages of the polar reversals based on previous studies of mid-ocean basalts indicate the poles start moving in wide circles becoming weaker and weaker and even essentially disappearing for a time. We seem to be in the stage of the poles moving. It is a coincidence, but we happen to be born in this time of reversal.

Answer 4

Without going into details (long, boring and technical) the Earth's magnetic force has very little effect on climate change.

In short - climate change is the result of changes within the atmosphere, such changes and the atmosphere per se are not magnetic.

The Earth's magnetic field is the result of the Earth's liquid centre moving over it's solid core. Magnetism is the result of subterranean activity, climate change is the result of atmospheric activity.

There will at some point in time be a reversal of polarity (we're half a million years overdue for this) but the climate will barely be affected. It's happened many times in the past with no noticeable change to climate.

Answer 5

this entire line of analyze is an attempt to coach techniques that would desire to be at artwork to reason the correlation between sunspots and earth temperatures that Svensmark and Friis Christensen have previoulsy theorized. yet you seem to have forgotten that Svenmark and Friis Christensen have admitted that their claimed correlation works in basic terms whilst the common history warming of .13 stages consistent with decaded is presented. They admitted this in a rebuttal to Lockwood and others who declare that at worst there is not any correlation and at appropriate any correlation ended 40 years in the past. the element is that whether this is shown that cosmic rays are the gadget by which photograph voltaic interest impacts earth temperatures, it does no longer address maximum folk of the warming interior the previous 40 years -- it does no longer even attempt to start explaining maximum folk of the warming of the previous 40 years. in actuality, all is shows is that warming led to by human interest will enhance up throughout the time of classes of ordinary or above ordinary photograph voltaic interest. whether Svenmark, Friis Christensen, Olaf Pepke Pedersen et al do teach to be appropriate (and there is not any such evidence yet) it is going to purely help the IPCC estimates by offering a proof for why the warming has been below the IPCC projected. It in basic terms shows that warming might have been a lot worse so some distance had we no longer been in a low-interest era, and that it could get a lot worse throughout the time of extra energetic classes. You seem to have forgotten that photograph voltaic interest has been low as earth temperatures has greater. this does not supply an option rationalization for the waming -- in basic terms an skill rationalization for cooling throughout the time of a era whilst there has been warming. like countless thoughtless denyer, you're grasping at straws quite than using scientific thinking.

Answer 6

Hello,

(ANS) That's non sense, the earths magnetic field is created deep down in the earths molten core. It is the molten magma that churns over and over miles and miles below our feet that creates the magnetic field.

YES! the earths magnetic field does fluctuate but there is NO! evidence to show the earth's magnetic field is becoming weaker.

**The solar wind or stream of particles that comes from the sun influences our magnetic field. Solar storms or solar mass ejection events can create havoc with telecommunications systems, such as mobile phone signals, TV reception,etc.

**The earths magnetic field consistency nor the solar wind affects the overall climate change or global warming. The Global warming we are now seeing is mainly influenced by human behavior & is due to the effects of :

a) pollution man made, over the last 150 years since the start of the industrial revolution and the invention of the internal combustion engine

b) our endless consumption of fossil fuels that release carbon into the stratosphere.

Answer 7

Perhaps the field is weakening or perhaps it is only changing its position within our globe.
Either way, the flow of solar particles will be affected which will affect our weather.
