Global temperature change attributable to external factors, finds new study Image credit: Shutterstock

Human activity is responsible for global temperature rise

Human-induced factors such as greenhouse gas concentrations, other occurrences such as volcanic eruptions, solar activity, and air pollution peaks are responsible for global temperature...

Converting methane into carbon dioxide could help turn the tide of climate change

Scientists at Stanford University, in a recent study, have suggested that converting methane to CO2 may help combat climate change. Doing this could help...
Carbon dioxide in the atmosphere just exceeded the highest level in human history

Carbon dioxide in the atmosphere just exceeded the highest level in human history

Carbon dioxide is the biggest contributor to climate change around the globe and stays in the atmosphere for many years after its emitted, making...
Drought. Low soil moisture posing threat in most river basins

Low soil moisture posing threat in most river basins

Factors like temperature, rainfall and soil moisture affect distribution and growth of vegetation. A study of these factors has shown that forest and croplands...
Climate vulnerability maps developed for Himalayan states

Climate vulnerability maps developed for Himalayan states

Receding apple lines, changing cropping patterns, more disasters like landslides and floods, drying springs in hills, spread of vector-borne diseases and so on. Such...

Sea ice acts as ‘pacemaker’ for abrupt climate change

The last glacial period was marked by pronounced millennial-scale variability in ocean circulation and global climate. Shifts in sea ice cover within the Nordic...

New tree rings analysis method may open insights to past climate

Accounting for both climate change and natural disturbances—which typically result in greenhouse gas emissions—is necessary to begin managing forest carbon sequestration. Gaining a complete...
Water towers of Asia contain less water than estimated

Water towers of Asia contain less water than estimated

The Himalayas are often called the water towers of Asia because of the vast amount of water locked in the form of ice in...
A new MIT study finds that over the coming decades climate change will affect the ocean’s color, intensifying its blue regions and its green ones.

Much of the surface ocean will shift in color by end of 21st century

The Earth's climate has changed throughout history. Just in the last 650,000 years, there have been seven cycles of glacial advance and retreat, with...
