Will Global Warming Save The Rain Forest? Possibly – but it definitely will help them, and biodiversity as well:
Climate change may lead to lush growth rather than catastrophic tree loss in the Amazonian forests, researchers from the US and Brazil have found. A study, in the journal Science, found that reduced rainfall had led to greener forests, possibly because sunlight levels are higher when there are fewer rainclouds.
But scientists cautioned that while the finding raises hopes for the survival of the forests, there are still serious threats. Climate models have suggested that the forests will suffer as the region becomes drier and will release huge quantities of carbon dioxide into the atmosphere.
These poor “the end of the world is here” types keep looking for the Apocolypse, and it just never shows up. Here is the problem – they models were wrong on what would happen, thus their shock at the results they are seeing:
Researchers identified the greener regions of the Amazon after analysing satelite images and comparing them to rainfall records. The 2005 drought provided them with â€œa unique opportunity to compare actual forest drought response to expectationâ€.
They said: â€œLarge-scale numerical models that simulate the interactions between changing global climate and terrestrial vegetation predict substantial carbon loss from tropical ecosystems including the drought-induced collapse of the Amazon forest and conversion to savanna.
â€œIf drought were to have the expected negative effect on canopy photosynthesis, it should have been especially observable during this period.
â€œThe observations of intact forest canopy â€˜greennessâ€™ in the drought region, however, are dominated by a sgnificant increase, not a decline.â€
To put it back into simple English are models were wrong again. I have to note some “science” for these people to ponder. Since their models are wrong, and the so called drought (actually reduced rainfall, not so much a drought) produced more greenery, then the Rain Forests are now producing MORE oxygen and consuming MORE of the atmospheric CO2. Somehow the fact more CO2 was available for the plants to thrive on (they consume CO2 like we consume O2, making plants and animals balanced compliments in Earth’s ecosystem) also seemed to be missing from these models. One of the things many have been saying is the Earth’s capacity to consume CO2 is not fixed, but it doesn’t adjust immediately. It may to take a few years for the plant biomass to adjust to the new CO2 levels, but it can adjust
So what do we know? They alarmists were wrong again. They went looking for signs of the pending disaster and found just the opposite. And while admitting they were wrong and their models were wrong, they still claim their models will be right some day. We know the increase in Rain Forest greenery will help the Rain Forests return, they will consume more CO2, and the ecosystem will blossom with more life. At least that is what we see so far.
There is global warming, but it is not man made or something new for our planet (it has happened many, many times before). It is a beautiful day here in the DC area. And the sky is not falling and the end of the world is not coming.
