The 2010 Northern Hemisphere summer heat waves included severe heat waves that impacted most of the United States, Kazakhstan, Mongolia, China, Hong Kong, North Africa and the European continent as a whole, along with parts of Canada, Russia, Indochina, South Korea and Japan during May, June, July, and August 2010. The first phase of the global heatwaves was caused by a moderate El Niño event, which lasted from June 2009 to May 2010. The first phase lasted only from April 2010 to June 2010, and caused only moderate above average temperatures in the areas affected. But it also set new record high temperatures for most of the area affected, in the Northern Hemisphere. The second phase (the main, and most devastating phase) was caused by a very strong La Niña event, which lasted from June 2010 to June 2011. According to meteorologists, the 2010–11 La Niña event was one of the strongest La Niña events ever observed. That same La Niña event also had devastating effects in the Eastern states of Australia. The second phase lasted from June 2010 to October 2010, caused severe heat waves, and multiple record-breaking temperatures. The heatwaves began in April 2010, when strong anticyclones began to develop, over most of the affected regions, in the Northern Hemisphere. The heatwaves ended in October 2010, when the powerful anticyclones over most of the affected areas dissipated. The heat wave during the summer of 2010 was at its worst in June, over the Eastern United States, Middle East, Eastern Europe and European Russia, and over Northeastern China and southeastern Russia. June 2010 marked the fourth consecutive warmest month on record globally, at 0.66 °C (1.22 °F) above average, while the period April–June was the warmest ever recorded for land areas in the Northern Hemisphere, at 1.25 °C (2.25 °F) above average. The previous record for the global average temperature in June was set in 2005 at 0.66 °C (1.19 °F), and the previous warm record for April–June over Northern Hemisphere land areas was 1.16 °C (2.09 °F), set in 2007. The strongest of the anticyclones, the one situated over Siberia, registered a maximum high pressure of 1040 millibars. The weather caused forest fires in China, where three in a team of 300 died fighting a fire that broke out in the Binchuan County of Dali, as Yunnan suffered the worst drought in 60 years by February 17. A major drought was reported across the Sahel as early as January. In August, a section of the Petermann Glacier tongue connecting northern Greenland, the Nares Strait and the Arctic Ocean broke off, the biggest ice shelf in the Arctic to detach in 48 years. By the time the heatwaves had ended in late October 2010, about $500 billion (2011 USD) of damage was done, in the Northern Hemisphere alone. The World Meteorological Organization stated that the heat waves, droughts and flooding events fit with predictions based on global warming for the 21st century, include those based on the Intergovernmental Panel on Climate Change's 2007 4th Assessment Report. Some climatologists argue that these weather events would not have happened if the atmospheric carbon dioxide was at pre-industrial levels.

The Bengal Famine of 1770 (Bengali: Chiẏāttôrer mônnôntôr, lit. The Famine of 76) was a famine that struck the Bengal region between 1769 and 1770 (1176 to 1177 in the Bengali calendar) and affected some 30 million people. It occurred during a period of dual governance in Bengal. This existed after the East India Company had been granted the diwani, or the right to collect revenue in Bengal by the Mughal emperor in Delhi, but before it had wrested the nizamat, or control of civil administration, which continued to lie with the Mughal governor, the Nawab of Bengal.Crop failure in autumn 1768 and summer 1769 and an accompanying smallpox epidemic were thought to be the manifest reasons for the famine. The Company had farmed out tax collection on account of a shortage of trained administrators, and the prevailing uncertainty may have worsened the famine's impact. Other factors adding to the pressure were: grain merchants ceased offering grain advances to peasants, but the market mechanism for exporting the merchants' grain to other regions remained in place; the Company purchased a large portion of rice for its army; and the Company's private servants and their Indian Gomasthas created local monopolies of grain. By the end of 1769 rice prices had risen two-fold, and in 1770 they rose a further three-fold. In Bihar, the continual passage of armies in the already drought-stricken countryside worsened the conditions. The Company provided little mitigation through direct relief efforts; nor did it reduce taxes, though its options to do so may have been limited.By the summer of 1770 people were dying everywhere. Although the monsoon immediately after did bring plentiful rains, it also brought diseases to which many among the enfeebled fell victim. For several years thereafter piracy increased on the Hooghly river delta. Deserted and overgrown villages were a common sight. Depopulation, however, was uneven, affecting north Bengal and Bihar severely, central Bengal moderately, and eastern only slightly. The recovery was also quicker in the well-watered Bengal delta in the east.Between seven and ten million people—or between a quarter and third of the presidency's population—were thought to have died. The loss to cultivation was estimated to be a third of the total cultivation. Some scholars consider these numbers to be exaggerated in large part because reliable demographic information had been lacking in 1770. Even so, the famine devastated traditional ways of life in the affected regions. It proved disastrous to the mulberries and cotton grown in Bengal; as a result, a large proportion of the dead were spinners and weavers who had no reserves of food. The famine hastened the end of dual governance in Bengal, the Company becoming the sole administrator soon after. Its cultural impact was felt long afterwards, becoming the subject a century later of Bankim Chandra Chatterjee's influential novel Anandamath.
