Climate change is often characterized as a significant alteration in average weather conditions over several decades or more, such as weather becoming wetter, warmer, or drier. Climate change is differentiated from natural weather fluctuation by its longer-term trend.

2. Is climate change a global issue?

Of course. Due to various internal and environmental causes, Climate change has become a worldwide issue. Furthermore, these climatic variations have various effects on life on Earth.

3. How will climate change affect the planet?

Climate change will affect temperature, ocean circulation, ice coverage, sea level, and frequency of extreme events. These changes will impact the structure and functioning of marine ecosystems, with feedback on global biogeochemical cycles and the climate system.

4. What are the natural causes of climate change?

The climate alteration could be caused by natural causes, such as oscillations in the solar cycle. The Earth experienced warming and cooling cycles. The sun’s intensity, the eruption of volcanos, and variations in naturally existing greenhouse gas concentrations are all forces that can contribute to climate change.

5. Does climate change vary from location?

Yes, it does vary. The form of the land is referred to as topography. The major components that cause surface temperature fluctuations are latitudes and elevation variations.

6. How does latitude affect climate shift?

Higher altitudes are farther from the equator and receive less sunshine, whereas lower latitudes receive more sunlight and are hotter than higher latitudes. Low precipitation or rainfall can also be caused by sunlight.

7. Are coastal areas warmer?

Not really! The distance from the sea and surrounding bodies of water is one of the crucial factors affecting a region’s climate. The surface temperatures of the sea impact the temperatures of the land. Coastal locations are more relaxed and wetter than interior areas as the ocean absorbs much heat from the atmosphere.

8. What is the scale of temperature rise?

The global average temperature increased by around 1.0°C from 1901 to 2016 and by 1.2o till 2021. Changes in the Earth’s average temperature of one or two degrees Celsius might produce potentially dangerous shifts in climate and weather. However, since the 1800s, human activities have been the primary cause of climate change, mainly due to fossil fuels like oil, coal, and gas.

9. Do humans cause climate change?

Aside from natural processes, humans have a significant impact on climate change. Human actions have a remarkable impact on climate change. Humans contribute to climatic change through deforestation, population growth, pollution caused by the combustion of fossil fuels, and emissions from automobiles and industry.

10. Does climate change affect other animals and plants?

Some of the known impacts of climate change on forests and biodiversity of Nepal include shifts in agro-ecological zones, prolonged dry spells, higher incidences of pests and diseases, shifting of treeline in the Himalayas, and depletion of wetlands. It also affects plant and animal life cycles. As temperatures rise, many plants, for example, begin to develop and bloom earlier in the spring and survive longer into the fall. Some animals wake up earlier from hibernation or migrating at various times.

11. What are the most severe consequences of climate change?

Rising temperatures resulting from human-caused greenhouse gas emissions have various effects on global systems. It, for example, warms the polar regions and oceans, causing ice cover at the poles to melt and sea levels to increase. Climate change impacts ocean environments by lowering oxygen levels and reducing flora.

12. What are the immediate and avoiding impacts of climate change?

Climate change directly impacts species by changing their physical environment, and it has an indirect impact on species by changing interspecific interactions like predation and competition.

13. Can we minimize climate change?

Yes. While we will not be able to stop global warming in the next few decades, we can slow the rate and limit the quantity of warming by lowering human-caused greenhouse gas emissions.

14. What are the significant steps to stop climate change?

The solution to minimizing climate change is to reduce green gas emissions as soon as possible. To put these proposals into action, international leaders joined the Paris Agreement in 2015. Some of the other significant steps to stop climate change are: to use renewable sources of energy, protect the rainforest, Green up your commute, and educate yourself and others.

15. What is the connection between climate change and health?

Climate change may affect health in various ways, including the increased frequency of extreme weather events such as heatwaves, storms, and floods, the disruption of food systems, increases in zoonoses and food-, water-, and vector-borne diseases, and mental health difficulties. Also, many of the social determinants of health, such as livelihoods, equality, access to health care, and social support networks, are under threat due to climate change.

16. How will the use of a renewable energy source help?

Changing our primary energy sources to clean and renewable energy is the most effective strategy to phase out the use of fossil fuels. Solar, wind, wave, tidal, and geothermal power are examples of such technologies. Concentrating your efforts on raising knowledge about renewable energy is the most effective method to make a positive difference in your community. You can persuade others to invest in renewable energy by informing them about how it is superior to using fossil fuels.

17. Is investing in recycling worth it?

Undoubtedly, investing in recycling would be a more environmentally friendly option. Recycling is a low-cost, environmentally beneficial method that reduces waste while emitting no greenhouse gases into the atmosphere.

18. What is the practical aspect of climate change in day-to-day life?

Millions of individuals drive to work every day. It is simply unavoidable in today’s world. The negative is that millions of cars create greenhouse gases that degrade our environment. Vehicle emissions are a close second to the leading causes of climate change. There are always other choices for making your journey to work more environmentally friendly. First, taking public transportation to work is an excellent method to reduce pollution. Riding your bike to work is also highly beneficial to the environment and a fantastic way to get some exercise.

19. How can you educate others about climate change?

Our modern society cannot stress the need to teach others about climate change. There are numerous platforms available to us that can help us convey our message. There are always methods to educate others on what climate change is happening to our planet, whether through word of mouth or social media. You may assist in safeguarding the environment by educating others about the dangers of climate change and how to combat it.

20. How does the Rainforest support planet’s well-being?

Rainforest is essential because it provides a home and sustainable livelihood to its inhabitants. It is a giant pool of biodiversity and is essential to the rest of the planet. These forests have a vital role in absorbing carbon dioxide, a greenhouse gas, and boosting local humidity, so rainforests are also known as the planet’s lungs

21. Are forests fighting climate alteration?

Forests are essential in the combat against climate modification, and their preservation is an essential climate solution. They are cutting down forests on a large scale, damaging massive trees that could absorb massive amounts of carbon. On the other hand, companies destroy forests to make space for animal farms, soya, or palm oil plantations. Governments can put a halt to it by enacting more vital legislation.

22. Does Climate change cause natural disasters?

Experts have recently established a strong link between climate change and natural disaster long-term patterns such as rising sea levels and temperatures. They’ve even demonstrated how climate changes influences and exacerbates natural disasters like floods, fires, droughts, and storms. However, a new sub-field of climate research has recently attracted interest and legitimacy in the climate science community.

23. When will our Earth end due to the climate crisis?

Is there, however, still time? Yes. It may still be feasible to reach the end of the century without exceeding the 1.5°C rise if countries worldwide pursue the “extremely low emissions” option, one of five outlined by the IPCC. The analysis revealed something exceedingly concerning: the 1.5°C limits of a reasonably “safe” temperature rise might well be achieved by the 2030s, a decade earlier than was expected just a few years ago.

24. Can you tackle climate change individually?

Yes, we can when we start conserving energy using renewable sources, which helps to keep fossil fuels in the ground. We should endeavor to reduce pollution and begin using environmentally friendly items. Also, not overuse of natural resources and plastics should be outlawed.

25. Why should you read Earth and Human blogs on climate change?

Earth and Human is a blog website operated by climate-conscious individuals of Nepal. The team of enthusiastic climate academicians from the fields of mountain ecology, zoology, forest covers, biodiversity, environment education, hydrological regime, sustainable society, and renewable energy have been continuously providing eye-opener articles for global climate welfare. The blog would trigger an essence of climate work needed for a better planet. You should go to and read one right now. 


Climate change has already begun to influence our environment more than we can imagine. Temperatures continue to rise worldwide, and precipitation patterns change in unprecedented ways. Pollution is the primary source of our planet’s disastrous impacts.

Also, Climate change is rising to the top of the political agendas in at least some countries. For example, a recent UK government report on the economic consequences of climate change stated that “now overwhelming of scientific evidence: climate change poses extremely substantial global hazards, and an urgent global response is required.
