    Dear World Leaders,

    Extreme weather or extreme climate events include unexpected,unusual,severe or unseasonal weather and that natural disasters cause a lot of damage to all of us.

    In the many years this has taken place, us humans have learnt that extreme weather is usually caused by the climate changes and this can really have an impact on our weather. Although, we cannot personally fix these natural disasters on our own, the little things that we can do to contribute to reduce greenhouse gases and climate change can tremendously help the earth even if we don’t realise that. For example, we can use energy wisely, turning off lights after we leave a room and when we don’t necessarily need it, we can make a huge difference. Turning off the stove, unplugging computer/phone cables when we don’t use them, and using energy-efficient light bulbs are things we might do already and that is helping reduce climate change in some way.

    Scientists have been deeply involved in the global warming trend since the mid-20th century and this is when the atmosphere traps heat radiating from Earth towards space. Some human actions are contributing to the greenhouse effect; burning fossil fuels like coal and oil in factories has increased the concentration of atmospheric carbon dioxide. Clearing of agriculture, industry has also increased concentrations of greenhouse gases. Even though we know these affect the greenhouse effect. We depend on fuels to heat our homes, run our vehicles, power industry and manufacturing, and most importantly provide us with electricity.

    The changes of greenhouse gases are very hard for scientists to predict but since the earth has been formed over 4.5 billion years ago, our climate has drastically changed many times. Research from the NASA climate change and global warming findings, shows that emissions from fossil fuels grew 1.5% in 2017, 2.1% in 2018 and another 0.6% in 2019. They are still not sure about the emissions during 2020 but hopefully the emissions level doesn't increase more and more.

    ,According to NOAA, sea level rose 3.3 millimeters per year between 1993 and the present. This past decade this trend accelerated a significant amount, rising almost 2 inches overall. It said to be that during 2018, our global sea level was the highest in the satellite light record. If our earth gets warmer and warmer these conditions will lead to more evaporation and precipitation and some areas with less water will become dryer. Especially in areas that grow it’s own crops, as crops vigorously use more water.

    Here are a few specific tips to handle some of the most common extreme weather emergencies:

    Remove dead or diseased trees near building
    Stay away from windows,outside walls and door
    Thunder and lightning
    If you are outside,avoid isolated tall trees
    If you are inside,steer clear of exterior windows
    Do not walk, swim,or drive through flood waters
    Construct barriers to keep flood water from entering your home
    Cover your nose
    Call firefighters to come to help

    Extreme cold,sleet and snow
    Dress in layers to keep warm and dry
    Don’t overexert yourself
