He Intergovernmental Panel on Climate Change (IPCC) presented a new report last Monday “Climate change 2023: summary reportcalling for “more ambitious” action to adapt to human-induced climate change and halve greenhouse gas (GHG) emissions by 2030.
Hoesung Lee, Chair of the Intergovernmental Panel on Climate Change (IPCC), points out the following:
The report also highlights that effective climate action taken now can lead us to a more sustainable, resilient and just world. And more ambitious measures will bring greater benefits to nature and society.hoesung lee
In 2018, the Intergovernmental Panel on Climate Change (IPCC) already warned of the enormous challenge of maintaining global warming to 1.5 ºC. Now, five years later, they point out that this challenge is even greater due to a prolonged increase in greenhouse gas (GHG) emissions.
António Guterres, Secretary General of the United Nations (UN)highlighted in a video message posted on Monday the following thoughts:
The report as a “practical guide to defusing the climate time bomb”. Developed country leaders must commit to net zero emissions as close to 2040 as possible. It can be done, some have already set the 2035 target, and countries in emerging economies must also commit to achieve net zero by 2050.Antonio Guterres
Hoesung Lee details the release of this new report as follows:
The report highlights the urgency for more ambitious action and shows that by acting now, we can still secure a sustainable and livable future for all.hoesung lee
What is Global Warming?
He climate change and global warming are concepts that we tend to confuse, since global warming is one of the aspects that includes climate change. Global warming is the increase in the average temperature of the oceans and the Earth’s atmosphere. This increase in temperatures has become increasingly alarming over the years.
The main cause that affects both climate change and global warming is the same. It is the massive emission of greenhouse gases (GHGs), which retain the heat they cause in the atmosphere and the surface of the Earth thanks to what is called the greenhouse effect. .
Climate change: burning fossil fuels
As detailed in the Intergovernmental Panel on Climate Change (IPCC) report, human activity has led to more than a century of burning fossil fuels. In addition, unsustainable energy and land use has caused global warming of 1.1°C above pre-industrial levels.
The report explains that if we are to keep temperatures 1.5ºC above pre-industrial levels, greenhouse gas (GHG) emissions will need to be reduced across all sectors during this decade. If we are to achieve this goal, we must start cutting these emissions today and nearly halve by 2030.
The consequences of these events manifest themselves on Earth in extreme weather events, which occur more frequently and with greater intensity, seriously affecting the most vulnerable populations. The Intergovernmental Panel on Climate Change (IPCC) proposes, among other solutions, the use of renewable energy, increased financing for climate investments and sustainable transport.
The report also notes that governments will play a key role in reducing greenhouse gas (GHG) emissions through public funding and clear signals to investors, expanding policy measures as necessary to achieve this goal.
Hoesung Lee speaks on this question as follows:
Transformation is more likely to succeed when there is trust, when everyone works together to prioritize risk reduction, and when benefits and burdens are shared equitably.hoesung lee

In February 2035, we will reach the 1.5°C limit
The fact that alarms all the experts dedicated to the study of climate change in the world is the increase in the rate of global warming of the planet. The Copernicus Climate Change Service (C3S) reports that the dates for reaching the 1.5°C limit have dramatically shortened the timelines.
The Copernicus Climate Change (C3S) service comments the following regarding this situation:
At the end of 2022, we calculated that this limit would be reached in 2035, while with the data for 2020 it was established for May 2045. Although the calculation changes every month, the data for the last few years still places it in the first half of the next decade.Climate Change Service (C3S)
