Humans Allegedly Set To Wipe An India-Sized Chunk Of Forest Off The Earth By 2050 -- or not
More prophecy based on a straight-line extrapolation. Loss of forest cover can be regrettable but we all live on land that was once forest so we can't just assume that any given loss is bad.
The article itself notes that anti-logging laws have largely mitigated any problem in the Amazon so it is mainly S.E. Asia that is losing its native forests. The forests there are being replaced by oil-palm plantations. So we are seeing a change in forest cover, not a loss of it.
If Greenies think that the change is deplorable they need to recognize that they and the food alarmists are responsible for it. Palm-oil is a profitable crop because of the various bans on dietary fats that have been put in place by food alarmists. First saturated fats were banned in food manufacturing and now trans-fats have just about been phased out. Palm oil is all that is reasonably left for manufacturers to use.
That the human race has been using saturated fats (such as dripping or tallow) in its cookery as far back as we can go does not faze the food alarmists. The flimsiest evidence that something is bad for you sends them into hysteria, eventually pushing weary legislators into giving them the bans that they want.
No doubt palm oil will also be found to be bad for you in due course so at that point the palm oil plantations will probably be replaced by pine planations. But Greenies don't like pines, either. There's no such thing as a happy Greenie
By 2050, an area of forests the size of India is set to be wiped off the planet if humans continue on their current path of deforestation, according to a new report. That’s bad news for the creatures that depend on these forest ecosystems for survival, but it’s also bad news for the climate, as the loss of these forests will release more than 100 gigatons of carbon dioxide into the atmosphere.
The report, published Monday by the Center for Global Development (CGD), found that, without new policies aimed at cutting back on deforestation, 289 million hectares (about 1,115,840 square miles) of tropical forests will be cleared away. That’s a chunk, the report states, that’s equal to one-seventh of what the Earth’s total tropical forest area was in 2000.
And, according to the report, the 169 gigatons of carbon dioxide that this deforestation will unleash is equal to one-sixth of the carbon budget that humans can emit if they want to keep warming below 2°C — the level that’s generally viewed as the maximum warming Earth can endure while still avoiding the most dangerous climate impacts (and even 2°C is seen by many experts as too high).
The study, unlike other recent studies on deforestation, projects that in a business-as-usual scenario, in which the world doesn’t make any effort to reduce deforestation, tropical deforestation will increase, rather than decrease. According to the study, tropical deforestation rates in such a scenario will likely climb steadily in the 2020s and 2030s and then speed up around 2040, “as areas of high forest cover in Latin America that are currently experiencing little deforestation come under greater threat.”
The study does point to one change in policy that would cut deforestation rates and help alleviate climate change: a price on carbon. According to the report, a price of $20 per ton of carbon would keep 41 gigatons of carbon dioxide from being emitted between 2016 and 2050, and a price of $50 per ton would keep 77 gigatons from being emitted.
“Our analysis corroborates the conclusions of previous studies that reducing tropical deforestation is a sizable and low-cost option for mitigating climate change,” the study’s authors write. “In contrast to previous studies, we project that the amount of emissions that can be avoided at low-cost by reducing tropical deforestation will increase rather than decrease in future decades.”
The study also noted that, if all tropical countries put in place anti-deforestation laws that were “as effective as those in the Brazilian Amazon post-2004,” then 60 gigatons of carbon dioxide would be kept out of the atmosphere. Brazil took action against deforestation in 2004 and 2008, and deforestation rates in the country have fallen from 27,000 square kilometers (about 10,424 square miles) in 2004 to 7,000 square kilometers (about 2,700 square miles) in 2010
