Solar Max


The most powerful flare ever observed was the first one to be observed, on September 1, 1859, and was reported by British astronomer Richard Carrington and independently by an independent observer named Richard Hodgson. The event is named the Solar storm of 1859, or the "Carrington event". The flare was visible to a naked-eye (in white light), and produced stunning auroras down to tropical latitudes such as Cuba or Hawaii. The flare left a trace in Greenland ice in the form of nitrates and beryllium-10, which allow its strength to be measured today (New Scientist, 2005). Cliver & Salvgaard (2004) reconstructed the effects of this flare and compared with other events of the last 150 years. In their words: While the 1859 event has close rivals or superiors in each of the above categories of space weather activity, it is the only documented event of the last 150 years that appears at or near the top of all of the lists.



On September 1–2, 1859, the largest recorded geomagnetic storm occurred. Aurorae were seen around the world, most notably over the Caribbean; also noteworthy were those over the Rocky Mountains that were so bright that their glow awoke gold miners, who began preparing breakfast because they thought it was morning. Telegraph systems all over Europe and North America failed in some cases even shocking telegraph operators. Telegraph pylons threw sparks and telegraph paper spontaneously caught fire. Some telegraph systems appeared to continue to send and receive messages despite having been disconnected from their power supplies.

The last solar maximum was in 2000. The next solar maximum is currently predicted to occur sometime between January and May 2013 and to be one of the weakest cycles since 1928. The unreliability of solar maxima is demonstrated in that NASA had previously predicted the solar maximum for 2010/2011 and possibly to occur as late as 2012. Previously, on March 10, 2006, NASA researchers had announced that the next solar maximum would be the strongest since the historic maximum in 1859 in which the northern lights could be seen as far south as Rome, approximately 42° north of the equator.

The next solar max could be powerful enough to knock out electric power grids around the world for months or even longer.

I wish my eyes weren't opened

because now that they are

I will have to do something

about the evil I see in the world

Today Is Earth Day: It's A Question of Survival


Earth Day is a day designed to inspire awareness and appreciation for the Earth's environment. It was founded by U.S. Senator Gaylord Nelson as an environmental teach-in in 1970 and is celebrated in many countries every year.

John McConnell first introduced the idea of a global holiday called "Earth Day" at the 1969 UNESCO Conference on the Environment. The first Earth Day proclamation was issued by San Francisco Mayor Joseph Alioto on March 21, 1970. Celebrations were held in various cities, such as San Francisco and in Davis, California with a multi-day street party. UN Secretary-General U Thant supported McConnell's global initiative to celebrate this annual event; and on February 26, 1971, he signed a proclamation to that effect, saying:

"May there be only peaceful and cheerful Earth Days to come for our beautiful Spaceship Earth as it continues to spin and circle in frigid space with its warm and fragile cargo of animate life."

John McConnell's concern for the environment grew in the late 1960s and early 1970s. He became moved when he saw the first picture of the Earth printed in Life magazine. Later that picture became the symbol on the Earth Day flag in which he designed and created. The Earth Day Flag was featured in "Whole Earth Catalogue" and was used, here and there around the world, to show support of efforts to help people and planet. The Earth Day Flag is a symbol of Earth Day and is still part of the Earth Day Ceremony each year at the United Nations.

On 22 April 1970, Earth Day marked the beginning of the modern environmental movement. Approximately 20 million Americans participated. Thousands of colleges and universities organized protests against the deterioration of the environment. Groups that had been fighting against oil spills, polluting factories and power plants, raw sewage, toxic dumps, pesticides, Freeway and expressway revolts, the loss of wilderness, and the extinction of wildlife suddenly realized they shared common values.

As Senator Nelson attests, the most impressive thing about this movement was how it had no central governing body and simply grew on its own:

"Earth Day worked because of the spontaneous response at the grassroots level. We had neither the time nor resources to organize 20 million demonstrators and the thousands of schools and local communities that participated. That was the remarkable thing about Earth Day...it organized itself." (read more)

The Malthusian Catastrophe


The Population Bomb was a best-selling book written by Paul R. Ehrlich in 1968. It warned of the mass starvation of humans in 1970s and 1980s due to overpopulation and advocated immediate action to limit population growth. The book also popularized the previously coined term, "population bomb". The book has been criticized in recent decades for its alarmist tone and unfilled predictions. Ehrlich stands by the basic ideas in the book.

Early editions of The Population Bomb began with the statement:

The battle to feed all of humanity is over. In the 1970s and 1980s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now. At this late date nothing can prevent a substantial increase in the world death rate.

The book dealt not only with food shortage, but also with other kinds of crises caused by rapid population growth. A "population bomb", as defined in the book, required only three things: a rapid rate of change, a limit of some sort, and delays in perceiving the limit.

Also worth noting is Ehrlich's introduction of the Impact formula or I PAT:

I = P × A × T (where I = Environmental Impact, P = Population, A = Affluence, T = Technology)

It states that the impact a community has on the environment, can be calculated by multiplying the community's population by its wealth and how developed it is. Ehrlich thus argued, affluent technological nations have a greater per capita impact on the limited resources of the earth than do poorer nations.

The world's population doubled from 3 billion in 1959 to 6 billion in 1999. It is currently (2010) at 6.8 billion, and is expected to reach 9 billion by around 2042.

More than 36 millions died of hunger or diseases caused by malnutrition in 2006. According to the World Health Organization, malnutrition is by far the biggest contributor to child mortality, present in half of all cases. Environmental issues with agriculture has hampered the finding of acceptable solutions to these problems.

In a 2004 Grist Magazine interview, Ehrlich acknowledged some specific predictions he had made, in the years around the time the Population Bomb was published, that had not come to pass. However, as to a number of his fundamental ideas and assertions he maintained that facts and science proved them correct.

In answer to the question: "Were your predictions in The Population Bomb right?", Ehrlich responded:

"Anne and I have always followed U.N. population projections as modified by the Population Reference Bureau -- so we never made "predictions", even though idiots think we have. When I wrote The Population Bomb in 1968, there were 3.5 billion people. Since then we've added another 2.8 billion -- many more than the total population (2 billion) when I was born in 1932. If that's not a population explosion, what is? My basic claims (and those of the many scientific colleagues who reviewed my work) were that population growth was a major problem. Fifty-eight academies of science said that same thing in 1994, as did the world scientists' warning to humanity in the same year. My view has become depressingly mainline!"

The book sold over two million copies, raised the general awareness of population and environmental issues, and influenced 1960s and 1970s public policy. (read more)
