Researchers get to grips with effects of heat, drought and storms on carbon release.
Climate change has a disconcerting tendency to amplify itself through feedback effects. Melting sea ice exposes dark water, allowing the ocean to soak up more heat. Arctic warming speeds the release of carbon dioxide from permafrost. And, as researchers discussed at a meeting last week in Seefeld, Austria, climate extremes heatwaves, droughts and storms can hamper plant growth, weakening a major buffer against the rise of CO2 in the atmosphere.
Heatwaves and droughts will very likely become more frequent in a warmer climate, and ecosystems will somehow respond, says Philippe Ciais, a carbon-cycle researcher at the Laboratory of Climate and Environmental Sciences in Gif-sur-Yvette, France. More storms will add an extra dimension to the problem.
The meeting was organized by the CARBO-Extreme project, a 3.3-million (US$4.5-million) collaboration of 27 groups from 12 countries, funded by the European Union. Attendees showed off an array of tools for uncovering how extreme events affect terrestrial carbon cycles, including numerical models, CO2 flux measurements and field experiments. The challenge now, says Ciais, is to predict how the frequency of climate extremes will change, and to model the intricate physiological responses some of which are poorly understood of plants and ecosystems.
Land plants create a huge carbon sink as they suck CO2 out of the air to build leaves, wood and roots. The sink varies from year to year, but on average it soaks up one-quarter of the annual CO2 emissions from the burning of fossil fuels. And events such as droughts, wildfires and storms are likely to cause a pronounced decline in the sink, says Markus Reichstein, a carbon-cycle scientist at the Max Planck...
So far, scientists have detected no increase in extreme weather events...

Those two articles take Greenhouse Theory at face value and by the criterion set up in the theory itself finds no evidence of warming on the basis of greenhouse effect.
"Forbes reports on a peer-reviewed study that uses NASA data to show that the effects of carbon-based warming have been significantly exaggerated. In fact, much of the heat goes out into space rather than stay trapped in the atmosphere, an outcome that started long before AGW alarmists predicted:"
That article explains why no Hot Spot has been found.
Those five articles each show that Greenhouse Theory has no basis in reality due to a direct conflict with the known laws of physics. No wonder the smoking gun "hotspot" can't be found.
That article kills any thought of planetary warming from any cause. Think about it. If there is absolutely no sign of rising sea levels how could the planet be warming? The rise in sea level in the last 100 years is almost exactly the same as the average over the last 40,000 years caused by the inter-glacial period we are in.
Oops. You have spoken out of line. Off to the gulags. No soup for you.
What they’re saying is “weather causes climate change”? Okay.
I hope that these so called "Researchers" are not "Cafeteria Climatologists," cherry picking data to support their preconceived notions that climate change (a reality) is man-made.
Climate change is caused by the Sun.
There has been no comprehensive systems analysis of all the factors involved in climate change on the Earth, Venus, and Mars.
Man made climate change does NOT cause asteroids.
Calling weather extreme simply hypes the weather channel and the AWG tax collection efforts. It’s all in the marketing plan.
Whenever I hear “greenhouse” as regards the earth I laugh. Where’s the glass globe blocking space?
As Reagan would say: “There you go again”..And here we go again with them mentioning CO2 even though the percentage of CO2 is zero point zero (0.04%) which has about as much of an effect on global warming as an ant fart.
Hoax hoax hoax! It's a hoax, folks.
