Air pollution never so high, taking action now can still change the world

The new report was particularly awaited IPCC after the dramatic appeal to the whole world last month. It is now useless to talk about last callin some ways the point of no return has already been passed but still we can – and must – think about mitigating the impacts of anthropogenic activity by slowing down the rise in the earth’s temperature. It is a primary issue for the current and future generations, especially considering that the past decade was the one in which they registered. the highest levels of greenhouse gases in the atmosphere in history (since when the detection tools exist).

In the Sixth Assessment Report, the Intergovernmental Panel on Climate Change warns that it does deep and immediate action is neededunder penalty of failure to achieve theobjective 1.5 ° C (which means reaching a peak in 2025 and reducing emissions by 43% by 2030). There is still a faint hope, because yes, pollution has never been as high as it is now, but the growth rate is slowing and this means that something good is being done, especially from the energy point of view with policies. ad hoc on the encouragement of renewables.

Goal 1 (preferred): containment of 1.5 ° C increase in temperature by 2050. Peak emissions by 2025, reduction of 43% by 2030.

Objective 2: containment of 2 ° C increase in temperature by 2050. Peak emissions by 2025, reduction of 25% by 2030.

WE HAVE THE MEANS

The IPCC is convinced that the path taken by many countries is the right one, now it is necessary to extend it globally to obtain first results that are an incentive for innovation. “We have the know-how“, reads the document signed by 195 governments, to halve emissions between now and 2030 and reach a 70% abatement in 2050 is not a utopia. And from here it must start – or rather, continue in a more decisive way – the energy revolutionwith the abandonment of fossil fuels in favor of renewable sources.

CITIES

The zero-energy and zero-carbon buildings they represent the future and, why not, the present. There are several cities in which eco-sustainable solutions are being implemented, an essential element for reducing emissions in highly urbanized areas. The IPCC stresses the importance of building small, compact cities so that people preferably walk rather than drive. As well as electrifying transport and creating green areas in the city to capture carbon.

THE INDUSTRY

The productive sector is called a reduce its impact along the entire supply chain, from the procurement of raw materials to disposal and recovery. Improving the process means emitting fewer greenhouse gases into the atmosphere, using eco-friendly materials, reducing waste and designing goods so that they can be easily recycled.

AGRICULTURE AND LAND USE

Reducing land use means limiting GHG emissions and allowing more plants and trees to storing CO2. The role played by agriculture and forestry will increase over the next few years.

ACT NOW

Now or never“, says Jim Skea of ​​IPCC. Taking all possible measures will still lead us to exceed the limit of 1.5 ° C, but only temporarily, and then return below the critical threshold.immediate and profound reductions in emissions in all sectors“, which make it possible to reach the goal of net-zero carbon (zero emissions net of offsets) as soon as possible. Only at that moment the global average temperature it will reach its own equilibrium, stabilizing itself. If this is not the case, irreversible constant overheating will occur.

The money is there, but it is not being spent properly. We need to invest, and a lot, but the benefits will outweigh the costs considering the positive effects on the environment, society and the economy. And not only the direct ones, but also the indirect and induced ones. IPCC Priyadarshi Shukla says:

Without taking into account the economic benefits of reducing adaptation costs or avoiding climate impacts, global GDP would only be a few percentage points lower in 2050 if we took the necessary actions to limit warming to 2 ° C or lower, compared to maintaining the current policies.
