Growing concern about the climate and peak oil essay

Wildfires need not be disastrous This is from the NYT, no less. In California, some communities aggressively prepare residents for the eventuality of wildfire. Montecito, a community east of Santa Barbara, saw the need to address wildfire risk following the Painted Cave Fire nearby, which killed one person and consumed homes. As the name suggests, defensible space is an area where a home can be defended by firefighters.

Posted on February 26, by curryja Comments by Javier Summary: Modern Global Warming has been taking place for the past years. It is the last of several multi-century warming periods that have happened during the Neoglacial cooling of the past years. Analysis of Holocene climate cycles shows that the period AD should be a period of warming.

The evidence suggests that Modern Global Warming is within Holocene variability, but the cryosphere displays a non-cyclical retreat that appears to have undone thousands of years of Neoglacial ice advance.

The last 70 out of years of Modern Global Warming are characterized by human-caused, extremely unusual, rapidly increasing CO2 levels.

In stark contrast with this rapidly accelerating anthropogenic forcing, global temperature and sea level appear to have continued their rising trend with no perceptible evidence of added acceleration.

The evidence supports a higher sensitivity to CO2 in the cryosphere, suggesting a negative feedback by H2O, that prevents CO2 from having the same effect elsewhere.

Background

It is characterized by a preponderance of warming periods over cooling periods, resulting in the warming of the planet, expansion of tropical areas, cryosphere contraction, sea level rise, and a change in dominant weather and precipitation patterns.

Afterwards, most of the eighteen century was warmer, but was followed by an intense cold relapse inbefore the LIA finally ended around The LIA is the closest the planet has been in 12, years to returning to glacial conditions.

But for the past years, MGW has interrupted the Neoglacial cooling trend of the last five millennia. There is great concern than this and other human actions deforestation, cattle raising, and changes in land use might have an important impact over climate, precipitating an abrupt climate change.

To some authors the abrupt climate change is already taking place. Climate variability over the past years. The time series is made from three segments covered by different amounts of data, which are kept constant within that segment. Each time series is plotted relative to its mean.

Main climatic periods are indicated by background color. Multi-centennial warming periods are indicated by horizontal continuous lines and vertical dotted lines. This series of articles has reviewed how the climate has been changing for the pastyears, and with greater detail for the past 12, years.

Climate change is the norm, and climate has never been stable for long. It is within this context of past climate change that MGW must be evaluated. Modern Global Warming is consistent with Holocene climatic cycles It is often said that MGW is unusual because it contradicts a Neoglacial cooling trend that has been ongoing for several millennia.

However, this is a superficial observation. Several multi-centennial warming periods have taken place within the Neoglacial cooling trend. Models simulate global cooling without anthropogenic forcing. However, the proposition that the world should be cooling absent an anthropogenic effect, contradicts our knowledge of Holocene climate cycles.

Centennial to millennial solar cycles.Food production is fundamental to our existence, yet we are using up the world's supply of phosphorus, a critical ingredient in growing food. Today, phosphorus is mostly obtained from mined rock phosphate and is often combined in mineral fertilizers with sulphuric acid, nitrogen, and potassium.

Warmist projection again In an article under the title "The Role Harassment Plays in Climate Change Denial", Leftist organ "Mother Jones" complains about criticisms directed at Warmists, completely ignoring the torrent of criticisms and threats that Warmists pour out at climate skeptics -- not to mention the many attacks on the livelihood of skeptics.
