A climate is the average weather in a given area over a period of time. The weather, on the other hand, can change drastically in a matter of hours. Changing the world takes thousands of years. It is, however, complex and has been growing at an alarming rate in recent years.
Weather refers to how the environment behaves, mostly in terms of its impacts on life and human habits. Temperature, humidity, precipitation, brightness, cloudiness, visibility, wind, and atmospheric pressure all are factors that influence the weather on a daily basis.
armer temperatures over time are changing weather patterns and disrupting the usual balance of nature. This poses many risks to human beings and all other forms of life on Earth.
Nearly all land areas are seeing more hot days and heat waves; 2020 was one of the hottest years on record. Higher temperatures increase heat-related illnesses and can make it more difficult to work and move around. Wildfires start more easily and spread more rapidly when conditions are hotter.
Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down forests and farming livestock.
This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
The main driver of climate change is the greenhouse effect. Some gases in the Earth's atmosphere act a bit like the glass in a greenhouse, trapping the sun's heat and stopping it from leaking back into space and causing global warming.
Many of these greenhouse gases occur naturally, but human activity is increasing the concentrations of some of them in the atmosphere, in particular:
CO2 produced by human activities is the largest contributor to global warming. By 2020, its concentration in the atmosphere had risen to 48% above its pre-industrial level (before 1750).
Other greenhouse gases are emitted by human activity in smaller quantities. Methane is a more powerful greenhouse gas than CO2, but has a shorter atmospheric lifetime. Nitrous oxide, like CO2, is a long-lived greenhouse gas that accumulates in the atmosphere over decades to centuries.
Natural causes, such as changes in solar radiation or volcanic activity are estimated to have contributed less than plus or minus 0.1°C to total warming between 1890 and 2010.
The World Wildlife Fund estimates over one-third of the planet's mangroves have already been cleared. They're often the victims of human encroachment and coastal development.
That was nearly the case in the United Arab Emirates. The country's meteoric rise in the late 1970s and 1980s meant that some of its mangrove forests were lost.
"The pace of development was much faster than any protection could be put on the ground, but luckily because of the commitment from our leadership, starting with Sheikh Zayed, the founding father of the UAE, mangroves were made a priority," explained Al Dhaheri. "Today, for any development to happen in Abu Dhabi, it has to go into a very rigorous permitting and licensing procedure to protect habitats."
The EAD's current priority is to protect the 140 square kilometers of mangrove forests growing along Abu Dhabi's coast. But the agency also helps rehabilitate damaged areas by planting new trees. Al Dhaheri says three million saplings have been planted in the last decade alone.
Using high-resolution satellite imagery, scientists estimate that Abu Dhabi's mangrove coverage has nearly doubled since the 1990s, but the images also revealed that a fifth of the mangroves are in moderate or deteriorating health.
A recent study says that a vast global restoration of forests of all kinds could capture two-thirds of the carbon humans have added to the atmosphere, making it one of the most sustainable and cost-efficient ways of fighting climate change.
EEG as an organisation accredited to UNEP, was invited to participate as a local partner, and launched its “Million Tree Project” in 2007 as part of UNEP’s campaign. EEG, by the end of 2007, had facilitated the pledging and planting of more than one million trees in UAE and the surrounding region.
With EEG’s active engagement with the community, it received pledges from various entities in UAE to support and plant trees under the “Million Tree Project”. By 2010, EEG had managed to exceed the target and plant 2,091,240 indigenous and well adapted trees within the UAE. This marked the culmination of the official affiliation with UNEP for the tree planting project, which went above and beyond in fulfilling its responsibility to the campaign.
