"From flight comb to farmer comb"

July went to history as the hottest month since the measurements began. In the new IPCC report, the message is unambiguous - it is not enough to phase out all fossil fuels to reach the goal of zero emissions by 2050: a challenge that currently appears insurmountable.

Several parties in Germany yesterday proposed a sharp increase in VAT on meat in Germany. German Social Democrats and the Greens support the proposal to increase from today's seven percent to 19 percent VAT on meat. The CDU government party is also positive.

Agriculture and forestry must be radically changed. We must grow food and use the forests in completely new ways. It is astonishing numbers that are emerging. Agriculture and forestry account for almost a quarter of global carbon dioxide emissions, according to the IPCC report.

The world needs more forest and fewer cows. It is not only the methane gas emissions of the cows that are a problem. The precious land that is used to grow fodder for cattle can make greater use of the climate if it is used to grow trees. It is the trees, not the cows, that are man's best friend in the fight against climate change.

In a drier and hotter world, it is the trees that bind the food soil, protect the groundwater and provide fodder, wood and medicines. Especially valuable are the coniferous forests in the Northern Hemisphere, which bind more coal per hectare than the rainforests. Therefore, the forest industry needs to rethink and allow forests to grow longer before they are harvested. The forests are to be used for timber to build climate-smart houses and not to become cardboard boxes, according to the IPCC.

But here is one of several target conflicts. The forests bind carbon dioxide. At the same time, the forest is increasingly desirable as a raw material for black liquor and other biofuels to replace the oil. Clearer political guidelines will be required for how to use the forest.

Another startling figure in the IPCC report is that 30 percent of the food produced in the world is either dried, rotten or thrown away. In many poor countries, farmers' products never reach their markets due to non-existent roads and poor access to transport and warehouses.

The challenges for the poor countries are enormous, they should avoid all mistakes rich countries with large-scale farming done, that is, better protect their wetlands and forests. At the same time, they need to increase their food production in an increasingly hot climate with more floods, forest fires and dry periods. It places demands on innovation in the aid industry. A paved road through the rainforest can be a climate-smart investment.

The aviation, motoring, coal power, cement industry and steel industry have already been secured to the climate crisis's pillar and now it is the turn of the forest and agriculture. But in many business sectors, intensive development work is also underway to find fossil-free alternatives, and this also applies to forestry and agriculture.

It is a vital nutrition for humanity, according to FAO, the world will need to increase its food production by 70 percent by 2050 to feed a growing population. With new and sustainable production methods, the green sectors can become part of the solution of the climate crisis.

The IPCC report suggests that those who protect ecosystem services should be paid, where agriculture and forestry can play a central role.

In Australia, the government has introduced the concept of "carbon farming". This means that the farmers who change their farming and forestry methods so that less CO 2 is released into the atmosphere should be rewarded. It can be about tying more organic matter into the soil, reforesting fields and protecting wetlands. For every tonne of CO 2 that remains in the soil and the forest, the farmer gets points that can be exchanged for money.

Ethiopia recently announced that they will plant four billion trees for climate reasons, just one day the government stated that 350 million tree plants were planted.

Australia and Ethiopia are constructive examples of more sustainable agriculture and forestry. But the big question is how the world's countries will have to deal with the powerful shift required.

For 12 years, the deadline for scientists has given the world's decision makers.
