Climate Change & Catastrophe

Let your hopes, not your hurts, shape your future”

Global warming, The past decade has been the warmest in recorded history. Deadly wildfires including those affecting Australia, hurricanes, extreme weather events in north-east India, and climate-influenced migration all our the world and hunger in many parts of the world are now regular occurrences. Ice caps are melting, sea levels are rising, and the very survival of island nations is being threatened. Indeed, our entire ecosystem is at risk: 1 million animal and plant species may be extinct within years, the largest-scale ecological loss humans have seen.

Not only it, let’s listen to environmental scientist what have they blame for ongoing worst-ever global pandemic:- The authors, from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), state, “There is a single species that is responsible for the Covid-19 pandemic – us. As with the climate and biodiversity crises, recent pandemics are a direct consequence of human activity.”

They warn, “Rampant deforestation, uncontrolled expansion of agriculture, intensive farming, mining and infrastructure development, as well as the exploitation of wild species, have created a ‘perfect storm’ for the spillover of diseases from wildlife to people. This often occurs in areas where communities live that are most vulnerable to infectious diseases.”

They say humanity has destroyed more than 85 per cent of wetlands and dedicates more than one-third of all land and most fresh water to crops and livestock production. “Add to this the unregulated trade in wild animals and the explosive growth of global air travel, and it becomes clear how a virus that once circulated harmlessly among a species of bats in southeast Asia has now infected almost 1o.5 million people all our world, brought untold human suffering and halted economies and societies around the world,” they write, adding: “This is the human hand in pandemic emergence.”

Now how to overcome from this catastrophe?

climatic change is solvable. We have the technologies. We have the science. We now need the leadership—and the courage to change course.

Carbon dioxide and other heat-trapping gases are the main drivers of global warming. While climate change cannot be stopped, it can be slowed.

To avoid the worst consequences of climate change, we’ll need to reach “net zero” carbon emissions by 2050 or sooner. Net zero means that, on balance, no more carbon is dumped into the atmosphere than is taken out.

To achieve net zero emissions, we need a massive transformation in how we produce and consume electricity. We need a newer, better transportation system. We need to stop deforestation. We need a climate-friendly agricultural system.  Much remains to be done—and we need to do it as quickly as possible.

Remove carbon dioxide

To reach net zero emissions, we need to do more than just reduce our emissions: we need to actively remove carbon dioxide from the atmosphere or offset its effects.

The easiest way to do this is by planting new forests (afforestation) or restoring old ones (reforestation). Other enhanced land management practices can help, as can new technologies that suck CO2 out of the air (“direct air capture”), or prevent it from leaving smokestacks  (“carbon capture and storage”).


The best policy ideas in the world aren’t worth much if we don’t have activists, experts, and everyday people fighting for change. From school groups to churches; from corporate boardrooms to mayors and local leaders: we need action.

The Union of Concerned Scientists has worked on global warming solutions for over 30 years. Our experts and activists are campaigning to cut emissions from the energy and transportation sectors; highlighting climate impacts; and fighting for accountability from major fossil fuel companies.
