“…For the Holocene a generally good correlation of 10 Be concentration in polar ice and ⌬ 14 C is found (Beer, 1994;Finckel and Nishiizumi, 1997). We are interested primarily in the 10 Be concentration of the atmosphere, which is related to the 10 Be concentration in ice through depositional processes (Finckel and Nishiizumi, 1997).…”

“…Earth-satellite measurements in the last two decades have revealed that the total energy reaching the Earth varies by at least 0.1% over the 10-to 11-year solar cycle (12). Evidence of larger and longer term variations in solar output can be deduced from geophysical data (13)(14)(15)(16)(17).…”

T he debate on the cause and the amount of global warming and its effect on global climates and economics continues. As world population continues its exponential growth, the potential for catastrophic effects from climate change increases. One previously neglected key to understanding global climate change may be found in examining events of world history and their connection to climate fluctuations.Climate fluctuations have long been noted as being cyclical in nature, and many papers have been published on this topic (1). These fluctuations also can be quite abrupt (2) when climate displays a surprisingly fast transition from one state to another. Possible causes of the cyclic variations and abrupt transitions at different time intervals have been theorized. These theories include internal drivers such as CO 2 concentrations (3), ocean temperature and salinity properties (4), as well as volcanism and atmospheric-transmissivity variations (5). External drivers include astronomical factors such as the Milankovitch orbital parameters (6), which recently have been challenged (7), and variations in the Sun's energy output (8-10).The most direct mechanism for climate change would be a decrease or increase in the total amount of radiant energy reaching the Earth. Because only the orbital eccentricity aspect of the Milankovitch theory can account for a change in the total global energy and this change is of the order of only a maximum of 0.1% (11), one must look to the Sun as a possible source of larger energy fluctuations. Earth-satellite measurements in the last two decades have revealed that the total energy reaching the Earth varies by at least 0.1% over the 10-to 11-year solar cycle (12). Evidence of larger and longer term variations in solar output can be deduced from geophysical data (13-17).In an extensive search of the literature pertaining to geophysical and astronomical cycles ranging from seconds to millions of years, Perry (18) demonstrated that the reported cycles fell into a recognizable pattern when standardized according to fundamental harmonics. An analysis of the distribution of 256 reported cycles, when standardized by dividing the length of each cycle, in years, by 2 N (where N is a positive or negative integer) until the cycle length fell into a range of 7.5 to 15 years, showed a central tendency of 11.1 years. The average sunspot-cycle length for the period 1700 to 1969 is also 11.1 years (19). In fact, the distribution of the sunspot cycles is very nearly the same as the distribution of the fundamental cycles of other geophysical and astronomical cycles. Aperiodicity of the cycles was evident in two side modes of 9.9 and 12.2 years for the geophysical and astronomical cycles and 10.0 and 12.1 years for the sunspot cycle. The coincidence of these two patterns suggests that solar-activity cycles and their fundamental harmonics may be the underlying cause of many climatic cycles that are preserved in the geophysical record. Gauthier (20) noted a similar unified structure in Quaternary climate data...

“…Primary production of meteoric 10 Be is controlled by solar activity and magnetic field intensity [ Masarik and Beer , 2009], both of which vary over time [ Beer , 1994; Frank et al , 1997]. The subsequent distribution of primary meteoric 10 Be is controlled by atmospheric circulation, with annual precipitation being a strong predictor of total meteoric 10 Be fallout at any one location [ Heikkilä et al , 2009].…”

Using 13 samples collected from a 4.1 meter profile in a well‐dated and stable New Zealand fluvial terrace, we present the first long‐term accumulation rate for meteoric 10Be in soil (1.68 to 1.72 × 106 at/(cm2·yr)) integrated over the past ∼18 ka. Site‐specific accumulation data, such as these, are prerequisite to the application of meteoric 10Be in surface process studies. Our data begin the process of calibrating long‐term meteoric 10Be delivery rates across latitude and precipitation gradients. Our integrated rate is lower than contemporary meteoric 10Be fluxes measured in New Zealand rainfall, suggesting that long‐term average precipitation, dust flux, or both, at this site were less than modern values. With accurately calibrated long‐term delivery rates, such as this, meteoric 10Be will be a powerful tool for studying rates of landscape change in environments where other cosmogenic nuclides, such as in situ 10Be, cannot be used.
