$100 billion a year in loss and damage funds for developing countries

Loss and Damage fund of $100 billion a year in climate finance for developing countries was approved at The 27th Conference of Parties (COP 27). The fund is for assisting developing countries that have contributed very little to the climate crisis and yet are vulnerable to the adverse effects of climate change.
The loss and damage arising from the adverse effects of climate change include related to extreme weather events but also slow onset events, such as sea level rise, increasing temperatures, ocean acidification, glacial retreat and related impacts, salinization, land and forest degradation, loss of biodiversity and desertification.
Human-induced climate change, including more frequent and intense extreme events, has caused some irreversible impacts as natural and human systems are pushed beyond their ability to adapt.
COP is the annual UN Summit on the environment and climate change, where all the world leaders come together to discuss and work towards climate change.
With around 1.2C of warming so far, the world has seen a cascade of climate-driven extremes in recent months, shining a spotlight on the plight of developing countries faced with escalating disasters, as well as an energy and food price crisis and ballooning debt. Scientists say limiting warming to 1.5C is a far safer guardrail against catastrophic climate impacts.
Concentrations of the main greenhouse gases – carbon dioxide, methane, and nitrous oxide – once again reached record levels in 2021. The annual increase in methane concentration was the highest on record.
LEARNING FROM HOME/ WITHOUT CLASSES/ BASICS
ANTHROPOGENIC CLIMATE CHANGE is a change caused by human activity.
CLIMATE CHANGE: Climate Change refers to any change in climate over time whether due to natural variability or as a result of human activity.
Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. The term is frequently used interchangeably with the term climate change, though the latter refers to both human- and naturally-produced warming and the effects it has on our planet.
Greenhouse gases allow sunlight (shortwave radiation) to pass through the atmosphere freely, where it is then partially absorbed by the surface of the Earth. Greenhouse gases are able to trap heat (longwave radiation) in the atmosphere, keeping the Earth’s surface warmer than it would be if they were not present. These gases are the fundamental cause of the greenhouse effect. Increases in the number of greenhouse gases in the atmosphere enhances the greenhouse effect which is creating global warming and consequently climate change.
So the more greenhouse gases you have in the atmosphere, the more heat stays on Earth. The principal forcing greenhouse gases are:
Carbon dioxide (CO2); Methane (CH4); Nitrous oxide (N2O); Fluorinated gases
UNFCCC
The UNFCCC entered into force on 21 March 1994. Today, it has near-universal membership. The 197 countries that have ratified the Convention are called Parties to the Convention.
The UNFCCC is a “Rio Convention”, one of three adopted at the “Rio Earth Summit” in 1992. Preventing “dangerous” human interference with the climate system is the ultimate aim of the UNFCCC. The ultimate objective of the Convention is to stabilize greenhouse gas concentrations “at a level that would prevent dangerous anthropogenic (human induced) interference with the climate system.”
PARIS AGREEMENT
The Paris Agreement is an agreement within the United Nations Framework Convention on Climate Change (UNFCCC) dealing with greenhouse gas emissions, mitigation and adaptation. The Paris agreement was signed in 2015 by 195 countries. The Paris Agreement entered into force on 4 November 2016. the Paris Agreement mandates all countries to take action to minimise the impact of climate change as per their voluntary commitments and individual capacity.
It sets a global goal of keeping global average temperatures from rising 2°C (compared to temperatures of pre-Industrial Revolution) by the end of the century.
