The evidence that humans are causing global warming is strong, but the question of what to do about it remains controversial. Economics, sociology, and politics are all important factors in planning for the future.

Even if we stopped emitting greenhouse gases (GHGs) today, the Earth would still warm by another degree Fahrenheit or so. But what we do from today forward makes a big difference. Depending on our choices, scientists predict that the Earth could eventually warm by as little as 2.5 degrees or as much as 10 degrees Fahrenheit.

Scientists have rather major plans to keep the earth surface cool.



Finding Nemo is getting harder as Climate Change is making clownfish infertile.

The homes of the clownfish that inspired the hit movie are being destroyed by warming seas in the South Pacific.

It’s stressing the colourful creatures out and reducing their sex drive, decimating numbers of offspring by three quarters.

Closely related to corals, sea anemones are invertebrate marine creatures that live in symbiosis with algae, which provide them with food, oxygen and color.



Every morning the world looks grim without a cup of coffee. It is the most important beverage to get us out of our sleepy state. Coffee is like a necessity for us. But imagine this necessity turning into a luxury; only available on occasions. Imagine “Koffee with Karan” without “Koffee”. Now that would be cruel.

But this would soon turn into reality. Climate Change is threatening coffee crops in every major coffee producing region of the world.

Higher temperatures, long droughts punctuated by intense rainfall, more resilient pests and plant diseases—all of which are associated with climate change—have reduced coffee supplies dramatically in recent years.

Coffee is the most traded commodity in world, after oil. Despite of not being staple in many diets, coffee business is big. Over 259 countries cultivate coffee and over 25 million families make a living from this business. But there is growing consensus among experts that climate change will affect coffee crops within the next 80 years. By 2100,over 50 percent of the land used to grow coffee will no longer be arable. A combination of effects, resulting from higher temperatures and shifting rainfall patterns, will make the land where coffee is grown unsuitable for its production.

According to the National Academy of Sciences, in Latin America alone, more than 90 percent of the land used for coffee production could suffer this fate. It is estimated that Ethiopia, the sixth largest producer in the world, could lose over 60 percent of its production by 2050. This is only a generation away.

Additionally, warming has expanded the habitat and thus the range and damage of the coffee berry borer, a grazing predator of coffee plants. This pest is placing additional stresses on all coffee crops, as is coffee rust, a devastating fungus that previously did not survive the cool mountain weather. Costa Rica, India, and Colombia, three of the top fifteen coffee-producing nations in the world, have all seen a dramatic decline in yields.

Brands like Maxwell House, Yuban, and Folgers have increased the retail prices of many grinds by 25 percent or more between 2010 and 2011, in light of tight supply and higher wholesale prices.

If you’re one of those people who needs a cup of coffee to get going in the morning, your world may be changing. In fact, it already is. The dwindling supply of coffee is but one example of the many impacts to come due to climate change, and should be a wake-up call for us all.



Climate Change needs a Plan. That much is obvious.

Over years we have come across numerous amount of news that state how much damage Climate Change is causing to our oh so precious Earth. But at the end of the day that news becomes a stale story which is long forgotten by next morning. We cannot deny the fact that we are facing this grave issue that is probably going to be around us for a long time.

So instead of just chit chatting about how Climate Change is harming us, we should rather prepare ourselves for its impact.

Preparing for Climate Change — also known as Climate Change Adaptation — is about reducing the risk of climate change impacts to people, places and resources. We know that climate change is already occurring, and that additional warming is unavoidable. If we hope to limit the negative impacts of climate change, we must prepare by identifying vulnerabilities and by planning accordingly.

The science of climate change is clear. The climate is already changing, and additional changes are unavoidable. This is because greenhouse gases — carbon dioxide and methane, for example — persist for a long time in the atmosphere, which allows the gases to accumulate over time. This also means we will experience a lag between when we reduce emissions and when we actually feel the benefits of that emissions reduction. Even if we halted all climate changing emissions tomorrow, the world would continue to experience accelerating climate change for years to come.

Since we cannot stop climate change, we must embrace climate change adaptation. In fact, since we cannot stop all the impacts of climate change, sometimes the best action may be to reduce other stressors in the ecosystem. For example, we cannot prevent sea level rise from flooding coastal marshes, but we may be able to increase the resilience of those marshes by reducing water pollution or protecting nearby natural areas from development.


Leaders take responsibility. We know the futility of blaming others, however much we indulge in doing so.

We can’t change the past. We can, however, act in the present.

A leadership and business perspective can help a lot in climate change, and I don’t mean by promoting technical innovation.

Responsibility is a hot topic in climate change debates. Who is to blame for climate change? Who has the duty to do something about it? These questions are particularly relevant in discussions about climate change mitigation that is, about who should reduce their carbon emissions and by how much.

Because these arguments are entwined with the attribution of praise or blame for action or lack thereof, they can be framed as a question about moral responsibility. Climate change poses a deep moral challenge because it concerns a problem caused by those who consume most but whose consequences will be mostly felt by those who are most deprived. The question here is whether responsibility should be adjudicated on the merits of an action or on its consequences.

The attribution of moral responsibility to an action has most often been discussed in relation to individuals because it requires not only finding an agent, but also establishing the agent’s intention, capacity, freedom and knowledge to do such action. Indeed, much research on climate change has approached the problem of responsibility for emissions abatement from the point of view of individual responsibility. This can be seen, for example, in studies that examine the basis for establishing personal carbon budgets or in those that seek to explain why individuals do not perceive climate change as a moral imperative to change their actions. However, a strictly analytical take based upon individual responsibility ideas may lead to the conclusion that, since climate change is “a problem of many hands” (many people share in the actions leading to it), “nobody is (in some sense) responsible for climate change”.

Overall, we can attribute varying degrees of responsibility to different parties but the sense of collective responsibility remains. The problem of collective responsibility for climate change is not confined to the sphere of government, as it pertains to both the material economy and the broader society whose values underpin existing production and consumption patterns. However, this collective responsibility cannot simply be distributed among all individuals because there are great differences in terms of access and use of carbon sinks and capacity to act (not only between countries, but also within countries).
