Climate sceptics, who had torn apart the IPCC's last report, are still looking for ways to manipulate public opinion. They know that public perception is not based on hard science, and that it can be influenced by getting a single message out - however distorted it may be. So even before the report was released, there was a selective leak that the report had found a "pause" - or the world was not warming as fast as predicted earlier. This word was quickly circulated, the media picked up the buzz, and they hoped opinion would be formed.

Unfortunately for the sceptics, this tactic cannot work so easily any more. People across the world are beginning to experience changes in the weather pattern. They are seeing increased activity of tropical typhoons; unseasonal and extreme rain events that lead to devastating flooding; extreme heat and cold and the melting of the Arctic ice. They hardly need the IPCC to tell them about the inevitability of climate change.

The fact is that the IPCC never said that there was a "pause". A selective reading of a leaked draft report was used to spread the canard. The final report states that the rate of warming over the past 15 years (1998-2012) is less than the rate calculated since 1951 per decade. But the report qualifies this by saying that the base year (1998) was when El Nino was the strongest and the world had seen higher-than-ever temperatures.

Therefore, not only is there no evidence of a pause but, on the contrary, there is proof that past scientific models and projections have been accurate and reliable. For instance, it is now confirmed that the atmosphere and oceans have warmed; the amount of snow and ice has diminished; and that the concentration of greenhouse gases released because of human activity has increased manifold. That is what should frighten us - not that scientific observations were wrong but that they were right.

For the Indian subcontinent, there is news and it is not good. This is the first time the IPCC has included special mention of the region's true finance minister, the monsoon. Till recently, most regional models did not take into account this capricious phenomenon, which rules our lives, so there was little knowledge about how precipitation patterns would behave in an increasingly warmer world.

Now the models project the following: there is medium confidence (IPCC terminology used when models predict less-than-high certainty) that Indian summer monsoon circulation will weaken but will be compensated by increased moisture content in the atmosphere because of warming oceans, ultimately leading to more precipitation. More rain is predicted but, worryingly, in fewer days. The monsoon, the IPCC says, will probably be most impacted by extremes in India compared to elsewhere. The IPCC report also says monsoon onset is likely to happen earlier and its retreat is very likely to be delayed, leading to longer rainy seasons.

While the IPCC juggles with the degree of likelihood - according to its definition, "very likely" signifies 90-100 per cent certainty and "likely" 66-100 per cent certainty - scientific theories are being enacted in the real world. In India we are seeing right now how the monsoon has still not retreated from the subcontinent - there is devastation in Gujarat, Uttar Pradesh and eastern India because of untimely rains. When extreme rainfall happened in Uttarakhand, which took more than 6,000 lives and destroyed an entire region, it was said that rains had come too early.

Therefore, it is time science led to action. At the global level, nations have to act to reduce emissions - drastically, urgently and keeping in mind issues of equity. At the national level, our agenda must be to cope with extreme, unseasonal and variable rainfall. This means becoming obsessive about water management. The fact is that climate change is not all bad news for us because it will rain more, not less. The key is to learn to hold the water, store it and recharge groundwater. It will also mean planning better to forecast extreme rain events so that we can mitigate the damage of an Uttarakhand-type calamity. It will mean doing all we know we must do: value the raindrop. Rural Development Minister Jairam Ramesh and Gujarat Chief Minister Narendra Modi were only half right when they said India needed toilets and not temples. In an increasingly warmer world, India's only temples can be the ditches, drains, lakes and rivers that can hold the rainwater and not let it cause floods or droughts - it is the revolution we are waiting for.
