Find here all of our live #CLIMAT
4:50 p.m. : This discussion is now over. Thanks to Gerhard Krinner for his answers and to you for your very interesting questions. You can find our article on the latest IPCC report here.
4:48 p.m. : At the individual level, the solutions really lie in food, the use of soft modes of transport, the consumption of goods produced locally, in season and generating low greenhouse gas emissions. One can also avoid financing, through one’s savings, the extraction of fossil resources. But the solutions are played out at all scales: the individual, the municipality, the region, the country and the international.
4:48 p.m. : Hello Sir, Thank you for what you do. If you live in a big city and you want to act for the climate, to make things happen on a daily basis, what are the professions of the future towards which to go, convert, or apply? towards which associations to go? How to have an impact? What are our solutions?
4:43 p.m. : Nuclear is mentioned in the report. The problem is that building new plants takes a long time. So to respond to the emergency, the potential is limited. Afterwards, it is true that nuclear power emits few greenhouse gases. For quick actions on energy, we can mention solar, wind, sobriety, diversification of energy sources…
4:41 p.m. : We know that photovoltaics and wind will not compensate for oil, gas and coal, there will be a lot of energy missing. The only real solution is nuclear power. Why, given the urgency, does the IPCC not pronounce on nuclear?
4:36 p.m. : All regions will be affected, with varying consequences. But everywhere, it is the most vulnerable populations who are already the most impacted. It is therefore the poorest who do not have the means to adapt and protect themselves. In developing countries, but also in rich countries.
4:35 p.m. : Hello mr krinner, which areas of the globe will be most affected by a warming of 4C° and in what ways will these areas be impacted?
4:35 p.m. : We are heading towards a stabilization of emissions, but that would not stabilize the climate. Warming would only stop when we reach net zero CO2 emissions.
4:35 p.m. : Greenhouse gas emissions continue to increase, but the rate of increase is slowing down a bit. We are therefore already seeing the effects of the measures put in place. But we are not at all on the right trajectory. If we take into account the policies currently voted, this would bring us to 2.2 to 3.5°C degrees in 2100.
4:28 p.m. : Have we observed even a slowdown in the production of greenhouse gases over the past 10 years?
4:34 p.m. : There are so-called “attribution” studies, which simulate climate change without human factors, in particular with natural factors such as volcanism or solar radiation. It is very clear that the climate would not have changed much over that century, it would have been constant.
4:22 p.m. : What would have been the evolution of the climate without the negative consequences of human actions?
4:21 p.m. : In France, almost all wastewater goes to treatment plants to be discharged into rivers or the sea, while in the United States, we drink water from toilets. So how to reuse wastewater in France at home and on a larger scale? Answer.
4:18 p.m. : Humanity “vampiric” To “broken the water cycle”endangering billions of people across the planet, denounces the Secretary General of the United Nations at the opening of the first UN conference on water for almost half a century. “We have (…) destroyed ecosystems and contaminated groundwater”launched Antonio Guterres.
4:17 p.m. : We are already observing, with this additional degree, increases everywhere in heat waves, extreme precipitation, diseases or even a retreat of glaciers, the mass of large ice caps or snow cover in the spring. Between +1.5°C and +2°C, the difference is very clearly discernible, especially for extreme events.
4:17 p.m. : We are already at +1.15°C compared to the period 1850-1900. This is a figure that will be found in the full report, which will be published shortly. We know that man is responsible for all of this warming.
4:17 p.m. : Mr krinner hello, could you just explain to people who are still climate-skeptical, what concretely changes 1 degree in their daily life? Many don’t realize the impact. Thank you and well done
4:20 p.m. : If we put in place more sustainable and less meaty diets, we can reduce the demand for agricultural land, leaving space for possible reforestation.
4:09 p.m. : Most deforestation is human-induced. It is done voluntarily. Reforestation can have beneficial effects, it can serve as a carbon sink in particular, but we must be careful not to carry out reforestation in monoculture, which is vulnerable. Or to the detriment of agricultural land, threatening food security. Above all, we must start by stopping deforestation in the tropics.
4:08 p.m. : Hello Mr Krinner, greenhouse gas emissions and rising temperatures have an impact on forest areas, which are constantly shrinking in some areas. Do you think reforestation can be a long-term solution, or is it too late?
4:09 p.m. : It was created to provide the scientific basis for international negotiations under the United Nations Framework Convention on Climate Change, which organizes the COPs. Its reports are approved sentence by sentence by the representatives of the States, so that, during the COP, we can focus on the solutions and not on the causes or the phenomenon.
4:01 p.m. : What role can the IPCC report play apart from being a whistleblower since 1990?
4:01 p.m. : Hello everyone, I am delighted to welcome in this live Gerhard Krinner, climatologist and co-author of the latest IPCC report. What are the conclusions of this new report on global warming? What are the consequences of the phenomenon on our lives? How does the IPCC work? Ask him your questions in the comment box with the keyword, he will answer them until 4:45 p.m.
4:00 p.m. : After a very dry summer and winter, the reserves are in tension and the water tables in a worrying situation, according to the Bureau of Geological and Mining Research. To fight against the lack of water, a breeder chose the “Keyline design” technique, a method from Australia to retain rainwater. Reporting.
