“We can’t take climate change and put it on the back burner. If we don’t address climate change, we won’t be around as humans" - Conrad Anker, American Rock Climber.
Climate change is the result of an imbalance between incoming and outgoing radiation in the atmosphere. It is the shift in climate patterns, mainly caused by greenhouse gas emissions from natural systems and human activities. The main driving force behind global warming is the heat generated through these emissions trapped by the earth’s atmosphere.
The report, The economics of climate change: no action not an option, published by the Swiss Re Institute, mention that the forecast about the impact of climate change is based on temperature increase The global mean temperatures may increase up to 3.2°C by 2050 and 5.4°C by 2100.
Climate change –
A threat to ecosystem, biodiversity, and health.
Is associated with alterations and modifications in the physical environment of the planet Earth.
Affects life around the globe and impact survival of the species.
Creates water and food insecurity, increased morbidity/mortality, and population movement.
Vulnerable populations (e.g., children, elderly, indigenous, and poor) are disproportionately affected.
The whole world is reeling under impact of climate change in the recent past. The climate change has pushed the world to a high risk in all aspects. The climate risk affects every country, every company and every individual.
Increase in temperatures, heavy rain fall, sea level rise and extreme weather would damage the property and critical infrastructure, impacting human health and productivity. This has also negatively affected sectors such as agriculture, forestry, fisheries and tourism.
Heatwaves, storms and floods due to Climate change also impact the health in a myriad of ways, resulting to illness and death.
5 main impacts of climate change are more frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans which can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities.
It is very much essential to mitigate that climate change risk with cooperation between the Government, public and private sectors to speed up the transition to net zero.
In order to achieve net zero, many countries are switching to renewable energy. The government is insisting the public to use energy efficient equipment which will reduce greenhouse gas effect. Conservation of energy and water is also will also help in mitigating the climate change impact. Conservation and restoration of forests will also help in mitigating the climate change impact. Reduce greenhouse gas emissions through food choices.
Mitigation efforts now employed in four main sector, viz., Energy, Industries, Transportation and buildings. In Energy / power sector, decarbonization can be achieved through the introduction of renewable energy, nuclear power, carbon capture and storage as well as supply-side fuel switch to low-carbon fuels such as natural gas and renewable fuels.
Afforestation and reforestation is one of the effective mitigation measure resulting in decarbonization.
Climate change and health.
Key facts of climate change and health as per WHO,
Between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhea and heat stress. The direct damage costs to health (i.e. excluding costs in health-determining sectors such as agriculture and water and sanitation), is estimated to be between USD 2-4 billion/year by 2030.

How Climate Change could impact the global economy.
The global economy could lose 10% of its total economic value by 2050 due to climate change, according to new research. The impact of climate change has been forecasted to be the hardest hit for Asian economies, with a 5.5% hit to GDP in the best-case scenario, and 26.5% hit in a severe scenario. Read more here.
With all the mitigation measures, with present pace of actions and cooperation between Government, Public and private sectors, can we achieve the net zero target by 2050?
