Explanation:

A disaster related to a weather, climate or water hazard occurred every day on average over the past 50 years – killing 115 people and causing US$ 202 million in losses daily, according to a comprehensive new report from the World Meteorological Organization (WMO).

The number of disasters has increased by a factor of five over the 50-year period, driven by climate change, more extreme weather and improved reporting. But, thanks to improved early warnings and disaster management, the number of deaths decreased almost three-fold.

According to the WMO Atlas of Mortality and Economic Losses from Weather, Climate and Water Extremes (1970 – 2019), there were more than 11 000 reported disasters attributed to these hazards globally, with just over 2 million deaths and US$ 3.64 trillion in losses.

The report is the most comprehensive review of mortality and economic losses from weather, water and climate extremes to date. It assesses the entire 50-year period as well as by individual decade.

From 1970 to 2019, weather, climate and water hazards accounted for 50% of all disasters, 45% of all reported deaths and 74% of all reported economic losses.

More than 91% of these deaths occurred in developing countries (using the United Nations Country Classification).

Of the top 10 disasters, the hazards that led to the largest human losses during the period have been droughts (650 000 deaths), storms (577 232 deaths), floods (58 700 deaths) and extreme temperature (55 736 deaths).

Deaths decreased almost threefold from 1970 to 2019. Death tolls fell from over 50 000 deaths in the 1970s to less than 20 000 in the 2010s. The 1970s and 1980s reported an average of 170 related deaths per day. In the 1990s, that average fell by one third to 90 related deaths per day, then continued to fall in the 2010s to 40 related deaths per day.

With regard to economic losses, the top 10 events include storms (US$ 521 billion) and floods (US$ 115 billion).

During the 50-year period, US$ 202 million dollars in damage occurred on average every day. Economic losses have increased sevenfold from the 1970s to the 2010s. The reported losses from 2010–2019 (US$ 383 million per day on average over the decade) were seven times the amount reported from 1970–1979 (US$ 49 million). Storms were the most prevalent cause of damage, resulting in the largest economic losses around the globe. It is the sole hazard for which the attributed portion is continually increasing.

Three of the costliest 10 disasters occurred in 2017: Hurricanes Harvey (US$ 96.9 billion), Maria (US$ 69.4 billion) and Irma (US$ 58.2 billion).  These three hurricanes alone accounted for 35% of the total economic losses of the top 10 disasters around the world from 1970 to 2019.

2. From each of the following pairs of atoms, pick the atom that has
Zina [86]

Answer:

a) Na

c) Na

b) Sr

d) Ca

Explanation:

As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required.

As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.

As the size of atom increases the ionization energy from top to bottom also  decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.

Find the average speed of a person who swims 105 m in 70 s
spin [16.1K]

Answer:

v = 1.5 m/s

Explanation:

Given that,

Distance covered by a person, d = 105 m

Time taken, t = 70 s

We need to find the average speed of the person. We know that the average speed is given by :

v=\dfrac{d}{t}\\\\v=\dfrac{105\ m}{70\ s}\\\\v=1.5\ m/s

So, the average speed of the person is equal to 1.5 m/s.

Name the postulates of Dalton atomic theory​
Elis [28]

Answer:

All matter consists of indivisible particles called atoms. Atoms of the same element are similar in shape and mass, but differ from the atoms of other elements. Atoms cannot be created or destroyed. Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms.

Hope this helps have a great day
