The evidence presented by the Intergovernmental Panel on Climate Change (IPCC) is a different matter. The whole climate change, let alone the low -level climate change, seems to be different and far -fetched.

The current evaluation cycle is in full swing and media res, among other things. The IPCC’s first report on climate change, released in February, confirmed the effects of climate change. This week’s pursuit of climate change will ensure that the change to net zero is ongoing, but not enough.

The claim that “we did not make a change in the climate” cannot be accepted. The report estimates that policymakers have avoided global emissions of about 1.8 gigatons per year. As a result, there are fewer of the most negative features. This is a fitting reminder for our organization, a reminder that we can work as a global community to reduce large emissions.

And there is more progress on the side. The report shows how political and technological development, higher renewable energy costs and public support for climate change, have “opened up new and significant opportunities. for deep decarbonization. “

However, these implementations are not sufficient. While global releases are rising at a rapid pace, they are still rising. Current policy implementations not only put us on the path to a slowdown in emissions by 2050. They predict global warming of 2.4 ℃ to 3.5 by 2100, which is a disastrous result.

Importantly, a flat release is a way of constant warming. If the air is swimming, this is like not turning the pipe, but leaving it as the swim continues, so that the swim is full in a stable place before climbing too much.

As the release continues, the earth’s temperature rises – just like water in a swimming pool. Essentially, the earth only consumes heat when we reach net-zero. Going back to the swimming model, which means we either completely remove the pipe or turn the pipe into a flow (hard discharges to eliminate) while releasing the same flow (removing carbon). dioxide from the air).

And if we want to return to lower echelons, we need to go further: we need to remove carbon from the atmosphere before it can be released. The higher the temperature we emit on earth, the greater the need to reduce the positive emotions that can disturb the climate.

What does this mean for Aotearoa New Zealand

In some countries, such as Aotearoa New Zealand, it is not easy to apply the standards of the IPCC report. As the IPCC itself finds, development approaches to net-zero differ from country to country, depending on “national standards and capabilities.”

However, the realities of net zero set the constraints on whether the change can take place. The decarbonization of energy cannot be discussed. In the words of the report: “Warming to 2 ° C or 1.5 ° C cannot be limited without rapid and profound reduction of the carbon dioxide energy system and global warming gas emissions. . “

In addition, the report argues that the early demolition of some fossil fuel industries (such as coal power) should meet the requirements of the Paris agreement.

Carbon dioxide emissions (CDR) can play a role in global mitigation initiatives. As the report puts it: “The proclamation of [carbon dioxide removal] It is not possible to avoid the residual emission if there is a net-zero CO₂ or green gas emission. ”

But the evidence is clear that removable carbon “cannot be a substitute for deep reduction.” With the world on track to burn off its carbon footprint by 1.5 ℃ before the end of these years, we need to use offsetting wisely, so it doesn’t interfere with reducing emissions. .

In this global context, there is a growing perception that New Zealand relies heavily on offsetting, both globally and at home, to fulfill its Paris agreements.

Fortunately, the report sheds light on how New Zealand can, if it chooses, reduce emissions quickly. Most of this we’ve heard before, but the new report shows opportunities to improve the city and housing design, decarbonize construction and industry, end demolition. in forests, sustainable agriculture and “transformational changes” in the transport and energy industry. Fortunately, there are more options in the last two districts.

The report sheds new light on the demand side: namely, avoiding high release services, moving to lower release options and improving the efficiency of existing services. He understands that non -vehicle movement is one of the main reasons for demand -driven mitigation.

To accomplish this, the report also found, with high confidence, that “it is better to move different types of policies than to have a single policy maker.” This should encourage the New Zealand government to move further towards enacting more merger policies that protect the Emissions Trading Scheme as a policy entity rather than its initial policy response.

The main defense, of course, is politics. The report recalls: “The relationship between politics, economics and power relations is crucial in explaining why public works are not always translated into fast -paced action.”

But this explanation only shows – motivated by signs of progress – where to continue.


Carbon dioxide naturally can help protect us from global warming.
