More CO2 required…benefits are enormous, and the science is peer reviewed

NIPCC report: Rising CO2 is beneficial

For those who want science and not politics, the enormous scientific compendium known as the NIPCC reports has been updated to incorporate new results. There are hundreds of references to peer reviewed research. It is as always, thorough, professional and comprehensive.

The authors of the new NIPCC report conclude that “the net effect of continued warming and rising carbon dioxide concentrations in the atmosphere is most likely to be beneficial to humans, plants, and wildlife.”

To summarize the executive summary:

  • The models overestimate the warming, don’t include chemical and biological process that may be as important as the physical ones.
  • Plants like CO2, grow faster and the green biomass of the Earth tends to counteract the warming effects of CO2.
  • New evidence shows the Medieval Warm Period was real, global and warmer than the present, while CO2 was 28% lower.
  • The ice is not melting as much as people expected; the seas are not accelerating; there’s no change in rain or river flows that you can blame CO2 on.
  • Life on Earth likes warmth. Amphibians, birds, butterflies, other insects, lizards, mammals, and even worms do better with a bit of global warming.
  • Warmth and CO2 increases crops and global food. It’s good for hungry people. More »
  • Read it all, I have been saying this for a long time now,  as long as I have had access to the internet. Even as long as I have studied horticulture.
  •  And as long as I have been a part of the Rural and Fishing Industries.
  • City folk have got a lot of catching up to, along with a number of science graduates from the Climate Change Department. Start here. Then read this. More still.
  •  It even reduces the severity of drought, farmers know this already.

I even tried to tell a journalist, but he wasn’t listening, and did not answer the letter I sent him.

About Tom Harley

Amateur ecologist and horticulturalist and CEO of Kimberley Environmental Horticulture Inc. (Tom Harley) Kimberley Environmental Horticulture Incorporated Kimberley Environmental Horticulture (KEH) is a small group of committed individuals who promote the use of indigenous plants for the landscaping of parks and gardens. Rehabilitation of Kimberley coast, bushland and pastoral regions are also high on our agenda. This includes planting seedlings, weed control, damage from erosion or any other environmental matter that comes to our attention. We come from all walks of life, from Professionals and Trades oriented occupations, Pensioners and Students, Public Servants and the Unemployed. We have a community plant nursery where we trial many old and new species, with a view to incorporating these into our landscaping trials. Our labour force are mainly volunteers, but with considerable help from the 'work for the dole' program, Indigenous Community Development Employment Program (CDEP) groups and the Ministry of Justice, with their community work orders; in this way we manage to train many people in the horticultural skills needed for indigenous plant growing. We constantly undertake field trips that cover seed and plant collection in the Kimberley. Networking around the Kimberley region and the east Pilbara is a necessary part of promoting our activities. We consult on a range of Environmental and Landscaping matters that deal with our region. Our activities involve improving Broome's residential streetscapes by including 'waterwise' priciples in planting out nature strips. Sustainable environmental horticulture is practised by members of our group. We use existing vegetation as the backbone of any plantings, using these species to advantage when planning to develop tree forms or orchards. The Broome region is sensitive to development. Subsequently many weed species have become dominant in and around developed areas. The use and movement of heavy machinery is the biggest single cause of environmental degradation. We dont live in a 'Tropical Paradise' but on the edge of the Great Sandy Desert. The plants that survive best here, grow in well-drained pindan sand, and are found from the Dampier Peninsular southward to where average rainfall is below 600mm. When we use rainforest species, detail is important when planting, water catchment, sunlight and understorey species are all considered. The use of recycled 'grey' water is an advantage here as well as treated waste-water, although many local species do not fare well with nutrients from this source. We use waterwise planting methods which include harvesting asmuch rainwater as possible, with swales designed to hold up to 200 litres, to help recharge the local groundwater aquifer. There has been a serious decline in this aquifer over the last few years. With the fast expansion of the Broome peninsular, more and more land is being covered by concrete, iron and bitumen so that much less water is available to replenish the aquifer, allowing the salt content to become significantly higher. The small Broome Peninsular is on the south-western corner of the Dampier Peninsular (bound by Broome, Derby and Cape Leveque at the northern tip). Compaction by vehicles also inhibits water retention due to the content of our local pindan sand, hard as concrete in the dry, going to soft and sloppy mud after rain. None of us are botanists, inevitably we have got some names wrong, names changed, or have not gone to sub-species level. If you note a photo or description may be wrong, please e-mail to
