Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that Earth’s climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks.
What are five types of evidence for global warming?
- Greenhouse Gas Emissions.
- Measurements and Observations.
- Nature of Climate Science.
- Ecosystem Changes.
- Plants and Animals.
- Melting Ice and Permafrost.
- Ocean Warming / Acidification.
What is physical evidence of climate change?
The physical impacts of climate change foremost include globally rising temperatures of the lower atmosphere, the land, and oceans . Temperature rise is not uniform, with land masses and the Arctic region warming faster than the global average.
What are the major signs of global warming?
- Arctic sea ice extent is diminishing.
- Ocean heat content is increasing.
- Air temperature over ocean is increasing.
- Sea surface temperature is increasing.
- Global sea level is rising.
- Humidity is increasing.
- Temperature of the lower atmosphere is increasing.
- Air temperature over land is increasing.
What are the 3 major types of physical evidence for climate change?
The physical and biological changes that confirm climate warming include the rate of retreat in glaciers around the world , the intensification of rainfall events, changes in the timing of the leafing out of plants and the arrival of spring migrant birds, and the shifting of the range of some species.
Where is climate change the worst?
The Arctic, Africa, small islands and Asian megadeltas and Australia are regions that are likely to be especially affected by future climate change. Africa is one of the most vulnerable continents to climate variability and change because of multiple existing stresses and low adaptive capacity.

How will climate affect us?
The impacts of climate change include warming temperatures, changes in precipitation, increases in the frequency or intensity of some extreme weather events, and rising sea levels . These impacts threaten our health by affecting the food we eat, the water we drink, the air we breathe, and the weather we experience.

- thawing permafrost.
What are the 4 main impacts of climate change?
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.
What are the 11 signs of climate change?

What is the Earth’s natural climate cycle?
The Earth’s natural climate cycle
Over the last 800,000 years, there have been natural cycles in the Earth’s climate. There have been ice ages and warmer interglacial periods. After the last ice age 20,000 years ago, average global temperature rose by about 3°C to 8°C, over a period of about 10,000 years .
