How do these events relate to Climate Change?

Scientists believe that the fluctuating weather conditions in a country suggest that the country is reeling under climatic chaos. For more than a decade now, the country has been experiencing contrasting extreme weather conditions: from heat waves to cyclones, from droughts to floods. Orissa for instance is a state, which is a classic example of climate change events. In addition to the extreme weather conditions, there have been instances such as destruction of mangroves along the coast, a fairly steep fall in agriculture and forest productivity, coral breeching etc which have been found.

From the angle of contribution to climate change, India figures among the top 10 countries of the world with the highest greenhouse gas emissions, with the total CO2 emissions from India estimated to be 1,001,352 Gg. India also emits over 250 tonnes of carbon every year.

why these are all happening , are we are the cause  ? whom to blame humans

Tropical Storm Agatha was a weak, but catastrophic tropical cyclone that brought widespread floods to much of Central America and was the deadliest tropical cyclone in the eastern Pacific since Hurricane Pauline in 1997. 

The first storm of the 2010 Pacific hurricane season, Agatha originated from the Intertropical Convergence Zone, which is a region of thunderstorms across the tropics.

It developed into a tropical depression on May 29 and tropical storm later, it was dissipated on May 30, reaching top winds of 45 mph (75 km/h) and a lowest pressure of 1000 mbar (hPa; 29.53 inHg).

It made landfall near the Guatemala–Mexico border on the evening of May 29. Agatha produced torrential rain all across Central America, which resulted in the death of one person in Nicaragua.

In Guatemala, 152 people were killed and 100 left missing by landslides. 13 deaths also occurred in El Salvador. It soon dissipated over Guatemala. As of June 15, officials in Guatemala have stated that 165 people were killed and 113 others are missing.
