user: Using examples taken from the paragraph, provide the major risks to humans with climate change in a short bulleted list

assistant: <think>
The effects of climate change are impacting humans everywhere in the world. Impacts can now be observed on all continents and ocean regions, with low-latitude, less developed areas facing the greatest risk. Continued warming has potentially “severe, pervasive and irreversible impacts” for people and ecosystems. The risks are unevenly distributed, but are generally greater for disadvantaged people in developing and developed countries.

The WHO has classified climate change as the greatest threat to global health in the 21st century. Extreme weather leads to injury and loss of life, and crop failures to undernutrition. Various infectious diseases are more easily transmitted in a warmer climate, such as dengue fever and malaria. Young children are the most vulnerable to food shortages. Both children and older people are vulnerable to extreme heat. The World Health Organization (WHO) has estimated that between 2030 and 2050, climate change would cause around 250,000 additional deaths per year. They assessed deaths from heat exposure in elderly people, increases in diarrhea, malaria, dengue, coastal flooding, and childhood undernutrition. Over 500,000 more adult deaths are projected yearly by 2050 due to reductions in food availability and quality. By 2100, 50% to 75% of the global population may face climate conditions that are life-threatening due to combined effects of extreme heat and humidity.

Climate change is affecting food security. It has caused reduction in global yields of maize, wheat, and soybeans between 1981 and 2010. Future warming could further reduce global yields of major crops. Crop production will probably be negatively affected in low-latitude countries, while effects at northern latitudes may be positive or negative. Up to an additional 183 million people worldwide, particularly those with lower incomes, are at risk of hunger as a consequence of these impacts. Climate change also impacts fish populations. Globally, less will be available to be fished. Regions dependent on glacier water, regions that are already dry, and small islands have a higher risk of water stress due to climate change.

Economic damages due to climate change may be severe and there is a chance of disastrous consequences. Climate change has likely already increased global economic inequality, and this trend is projected to continue. Most of the severe impacts are expected in sub-Saharan Africa, where most of the local inhabitants are dependent upon natural and agricultural resources and South-East Asia. The World Bank estimates that climate change could drive over 120 million people into poverty by 2030.

Current inequalities based on wealth and social status have worsened due to climate change. Major difficulties in mitigating, adapting, and recovering to climate shocks are faced by marginalized people who have less control over resources. Indigenous people, who are subsistent on their land and ecosystems, will face endangerment to their wellness and lifestyles due to climate change. An expert elicitation concluded that the role of climate change in armed conflict has been small compared to factors such as socio-economic inequality and state capabilities.

Low-lying islands and coastal communities are threatened by sea level rise, which makes flooding more common. Sometimes, land is permanently lost to the sea. This could lead to statelessness for people in island nations, such as the Maldives and Tuvalu. In some regions, the rise in temperature and humidity may be too severe for humans to adapt to. With worst-case climate change, models project that almost one-third of humanity might live in extremely hot and uninhabitable climates, similar to the current climate found in the Sahara. These factors can drive environmental migration, both within and between countries. More people are expected to be displaced because of sea level rise, extreme weather and conflict from increased competition over natural resources. Climate change may also increase vulnerability, leading to "trapped populations" who are not able to move due to a lack of resources.</think>
- Major threat to global health due to extreme weather, crop shortages, and increases in infectious diseases (more easily transmitted in warmer weather)

- Effects to food security due to crop yield reduction and impacts to fish population

- Economic damages from adverse weather events and dislocations on natural and agricultural resources

- Increases in wealth and socioeconomic inequalities as climate change impacts marginalized populations who depend on land and associated ecosystems

user: Given this reference text about the career of Charles Henry Bromedge Caldwell, name the ships he commanded after his promotion to the rank of Commander.

assistant: <think>
Charles Henry Bromedge Caldwell was born in Hingham, Massachusetts on February 24, 1823. He entered the navy as midshipman February 27, 1838, and became lieutenant September 4, 1852. He commanded the USS Vandalia in the US Navy's second Fiji expedition, an 1859 punitive expedition against Waya Island warriors who had cannibalized two American traders. In 1862, he commanded the gun-boat Itasca, of the western gulf blockading squadron, and took part in the bombardment of Forts Jackson and St. Philip. On the night of April 20, his gun-boat, with the Pinola, was sent on an expedition under the command of Fleet-Capt. Bell, to make a passage for the fleet through the chain obstructions near the forts. Lieut. Caldwell and his party boarded one of the hulks that held the chains, and succeeded in detaching the latter, in spite of the heavy fire to which they were subjected. The Itasca was then swept on shore by the current, in full sight of the forts, and it was half an hour before she was afloat again. She was unable to pass the forts with the rest of the fleet, owing to a shot that penetrated her boiler. Lieut. Caldwell was in the action at Grand Gulf, June 9, 1862, and was promoted to commander on July 16 1862.

He commanded the iron-clad Essex, of the Mississippi squadron in 1862–63, and took part in the operations at Port Hudson, from March to July 1863, in command of the Essex and the mortar flotilla.

He commanded the Glaucus of the North Atlantic blockading squadron from 1863 till 1864, and the R. R. Cuyler, of the same squadron, from 1864 till 1865. He became captain, December 12, 1867, chief of staff of the North Atlantic fleet in 1870, and commodore on June 14, 1874.

He died on November 30, 1877.</think>
