Worth reading the entire blog entry there.
Sprite Streamers: Storms' Hyper-Velocity Ball Lightning?
New high speed video of sprites above thunderstorms!
Massive high speed ball lightning? From the video it looks like the charges descend from above the storm! As ball lightning.
That is incredibly awesome.

Contrails, (Kerosene, Water Vapor, Sulfur Dioxide, Nitrous Oxide, Carbon Dioxide), Ozone and Climate
This one is so huge it defies easy description. Some info and links, more to be added. I've spent months on this, just starting to collate and make some sense of it.
Cirrus clouds are formed when water vapor freezes into ice crystals at altitudes above 8000 meters (26,000 ft).
The stratosphere is situated between about 10 km (6 miles) and 50 km (31 miles) altitude above the surface at moderate latitudes, while at the poles it starts at about 8 km (5 miles) altitude.
The Antarctic ozone hole is produced every spring over the earth's south pole because of the special conditions that are present in the stratosphere over Antarctica and the presence of completely anthropogenic chemicals spilled into the environment called chlorofluorocarbons (CFCs).
Since 1974 scientists have known that chlorine can destroy ozone, but no one thought the destruction would be very rapid. Events over the Antarctic region proved them wrong. The ozone hole story began at Halley Bay in Antarctica, where British scientists had been measuring ozone in the atmosphere since 1957. In 1976 they detected a 10% drop in ozone levels during September, October, and November—the Antarctic spring.
Since ozone concentrations over this region often vary from season to season, the researchers weren't concerned, even as the springtime declines occurred repeatedly. It wasn't until their instruments registered record low levels of ozone in 1983 that they realized something important was happening. By then, record springtime ozone declines had occurred during seven of the previous eight years.
Using satellite images of sea ice and computer models the scientists discovered that the ozone hole has strengthened surface winds around Antarctica and deepened the storms in the South Pacific area of the Southern Ocean that surrounds the continent. This resulted in greater flow of cold air over the Ross Sea (West Antarctica) leading to more ice production in this region.
Fact: There is no such thing as a "Chemtrail". Contrails are safe and are a natural phenomenon. They pose no health hazard of any kind.
Abstract. This study is devoted to the possible presence of cirrus clouds in the stratosphere.
Abstract The distribution of many chemical constituents of the atmosphere (e.g., ozone) is at least partially determined by the distribution of net radiative heating in the atmosphere. In this paper, we demonstrate the significant effect of high cirrus clouds on the net radiative heating of the tropical lower stratosphere.
Using simulations, we determine the influence of stratospheric aerosol and thin cirrus clouds on the performance of the proposed atmospheric correction algorithm for the moderate resolution imaging spectroradiometer (MODIS) data over the oceans.
Nitrous oxide is emitted from natural sources and as a byproduct of agricultural fertilization and other industrial processes. Calculating the effect on the ozone layer now and in the future, NOAA researchers found that emissions of nitrous oxide from human activities erode the ozone layer and will continue to do so for many
The recent SUCCESS measurements made right behind jet engines reveal that the sulfuric acid forms either within the engine or immediately after it is ejected, says Anderson.
What this observation means for clouds and climate remains unclear. Yet many meteorologists think that increasing jet traffic in the last several decades has altered weather in noticeable ways.
In 1981, climatologist Stanley A. Changnon of the Illinois State Water Survey in Champaign reported that the Midwest had grown significantly cloudier during the 1960s and 1970s, with the greatest changes seen in areas of high jet traffic.
He also noted a narrowing of the gap between high and low temperatures, possibly attributable to the increase in clouds.

Not science based, but sometimes you have to laugh.
How much is man made?
Different sites say different things.
Why does it rise?
There are mysteries still.
Skeptical Science has a page
How much is from volcanoes is a real mystery.
How do volcanoes effect climate?
Many interesting things are online. Some people are skeptical.
I can't blame them, I mean,
active volcano to measure CO2?
Lots of interesting information on that blog.
Monitoring CO2 elsewhere.
This entry is mostly saving links so I can look into this later.

From National Geographic no less
Emerging evidence is painting a very different scenario, one in which rising temperatures could benefit millions of Africans in the driest parts of the continent.
Scientists are now seeing signals that the Sahara desert and surrounding regions are greening due to increasing rainfall.
An explosion in plant growth has been predicted by some climate models.
For instance, in 2005 a team led by Reindert Haarsma of the Royal Netherlands Meteorological Institute in De Bilt, the Netherlands, forecast significantly more future rainfall in the Sahel.
The study in Geophysical Research Letters predicted that rainfall in the July to September wet season would rise by up to two millimeters a day by 2080.
Satellite data shows "that indeed during the last decade, the Sahel is becoming more green," Haarsma said.
Even so, climate scientists don't agree on how future climate change will affect the Sahel: Some studies simulate a decrease in rainfall.
"This issue is still rather uncertain," Haarsma said.
Max Planck's Claussen said North Africa is the area of greatest disagreement among climate change modelers.
Forecasting how global warming will affect the region is complicated by its vast size and the unpredictable influence of high-altitude winds that disperse monsoon rains, Claussen added.
"Half the models follow a wetter trend, and half a drier trend."
One reason I am skeptical of Climate Science.

... taking into account the data recorded for the level of solar radiation, the scientists made a surprising discovery: in the 1940s and in the summer of 1947 especially, the glaciers lost the most ice since measurements commenced in 1914. This is in spite of the fact that temperatures were lower than in the past two decades. "The surprising thing is that this paradox can be explained relatively easily with radiation," says Huss, who was recently appointed to the post of senior lecturer at the Department of Geosciences at the University of Fribourg in Switzerland.
On the basis of their calculations, the researchers have concluded that the high level of short-wave radiation in the summer months is responsible for the fast pace of glacier melt. In the 1940s, the level was 8% higher than the long-term average and 18 Watts per square metres above the levels of the past ten years. Calculated over the entire decade of the 1940s, this resulted in 4% more snow and ice melt compared with the past ten years.
Furthermore, the below-average melt rates at the measurement points during periods in which the glacier snouts were even advancing correlate with a phase of global dimming, between the 1950s and the 1980s.
The scientists emphasize that the rapid expansion of human activities since the industrial revolution has now generated a global geophysical force equivalent to some of the great forces of nature.
"We are entering the Anthropocene, a new geological era in which our activities are threatening the Earth’s capacity to regulate itself. We are beginning to push the planet out of its current stable Holocene state, the warm period that began about 10,000 years ago and during which agriculture and complex societies, including our own, have developed and flourished," says co-author Professor Will Steffen, Director of the ANU Climate Change Institute at The Australian National University. "The expanding human enterprise could undermine the resilience of the Holocene state, which would otherwise continue for thousands of years into the future."First assumption, the Earth regulates itself.
Second assumption, that the author of this piece knows what the future holds.
Neither are presented with evidence, theory and the peer reviewed process normally required for scientific knowledge to be accepted.

Effects were mostly concentrated in kidney and liver function, the two major diet detoxification organs, but in detail differed with each GM type. In addition, some effects on heart, adrenal, spleen and blood cells were also frequently noted. As there normally exists sex differences in liver and kidney metabolism, the highly statistically significant disturbances in the function of these organs, seen between male and female rats, cannot be dismissed as biologically insignificant as has been proposed by others..
We therefore conclude that our data strongly suggests that these GM maize varieties induce a state of hepatorenal toxicity. This can be due to the new pesticides (herbicide or insecticide) present specifically in each type of GM maize, although unintended metabolic effects due to the mutagenic properties of the GM transformation process cannot be excluded.
