Effects that scientists had predicted in the past would result from global climate change are now occurring:
loss of sea ice, accelerated sea level rise and longer, more intense heat waves
.
What is global warming in easy words?
Global warming is
the unusually rapid increase in Earth’s average surface temperature over the past century
primarily due to the greenhouse gases released as people burn fossil fuels. … Temperatures are certain to go up further.
What are the effects of global warming?
Global warming stresses
ecosystems through temperature rises, water shortages, increased fire threats, drought, weed and pest invasions
, intense storm damage and salt invasion, just to name a few.
What is global warming what are its effects Class 9?
“Global warming is
a gradual increase in the earth’s temperature
generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
What is global warming and its causes and effects?
Modern global warming is the result of an
increase in magnitude of the so-
called greenhouse effect, a warming of Earth’s surface and lower atmosphere caused by the presence of water vapour, carbon dioxide, methane, nitrous oxides, and other greenhouse gases.
What is the main cause of global warming?
Greenhouse gases
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.
How does global warming affect humans and animals?
Impacts. Humans and wild animals face new challenges for survival because of climate change. More
frequent and intense drought, storms, heat waves, rising sea levels
, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities.
How does global warming affect us?
Extreme heat and poor air quality increase complications from
underlying heart and respiratory conditions
like asthma, renal failure, and pre-term birth, and as temperatures rise, there will be more heat-related illness and deaths in both urban and rural areas.
What is global warming and how can we reduce it?
While we cannot stop global warming overnight, or even over the next several decades, we can slow the rate and limit the amount of global warming by
reducing human emissions of heat-trapping gases and soot (“black carbon”)
. … Once this excess heat radiated out to space, Earth’s temperature would stabilize.
What are the 10 causes of global warming?

- Transportation. …
- Farming. …
- Deforestation. …
- Fertilizers. …
- Oil Drilling. …
- Natural Gas Drilling. …
- Permafrost.
How we can stop global warming?
- Speak up! …
- Power your home with renewable energy. …
- Weatherize, weatherize, weatherize. …
- Invest in energy-efficient appliances. …
- Reduce water waste. …
- Actually eat the food you buy—and make less of it meat. …
- Buy better bulbs. …
- Pull the plug(s).
What is greenhouse effect and its causes?
The greenhouse effect is a process that
occurs when gases in Earth’s atmosphere trap the Sun’s heat
. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.
What are the causes and effects of global warming essay?
Causes and Effects of Global Warming Essay:
The emissions of greenhouse gases have
caused global warming. One of the many effects of global warming is that it has led to an increase in the planet’s temperatures. The leading cause of global warming is the release of harmful and toxic gases into the atmosphere.
What are the 5 causes of global warming?
- Greenhouse Gases Are the Main Reasons for Global Warming. …
- Cause #1: Variations in the Sun’s Intensity. …
- Cause #2: Industrial Activity. …
- Cause #3: Agricultural Activity. …
- Cause #4: Deforestation. …
- Cause #5: Earth’s Own Feedback Loop.
What is the biggest cause of climate change?
Human activity
is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. … Burning fossil fuels produces carbon dioxide, a greenhouse gas. It is called a greenhouse gas because it produces a “greenhouse effect”.
What is the biggest contributor to global warming?
Electricity and Heat Production
(25% of 2010 global greenhouse gas emissions): The burning of coal, natural gas, and oil for electricity and heat is the largest single source of global greenhouse gas emissions.
